Need Coax digital out on Mac Pro

Hi,
Title says it all... do not want to convert optical to coax, rather a card for the Mac Pro that has high quality coax out. Only one I found was the M-Audio Audiophile 192, however, seems to be G5 only (may be out of date spec). Anyone have experience with this card in a Mac Pro or know of another card?
Thanks!
Jim

The Audiophile 192 won't work with a Mac Pro because it's a PCI card and Mac Pro have PCI Express slots. There's few PCI Express audio cards and every one of them I know use an External breakout box anyway. You're probably better to do a search for a Firewire interface.

  • Playstation 3 Digital out to Mac Pro 3,1 Digital in and out again through Konnekt 6

    So I got a used Mac Pro 3,1 on craigslist and it's a beast.  Only problem is that the superdrive was broken.  No big deal really, but I've been thinking about how it'd be cool to be able to watch blu-ray movies on it. I Could just buy an 80 dollar drive, or I could use my Playstation.  I've got optical outputs on the PS3 and inputs on the Mac, so my question is what the easiest way to route the sound would be.  Just using audio/midi setup? Usually inputs need to be "armed" so that there isn't that constant stream of info and I imagine with digital it's the same?  Would I have to open up Logic and do some kind of soundflower bed magic?
    Thanks!

    Ok so I'm home now and continued my seach... and found this:

    I won't be able to try it until back in the studio tomorrow but it may just be what I need - will report back here. Seems that it is an OS issue though and not an Adobe one.

    do i need a antivirus for my mac pro?
    At this time, you do not need it. There are ways that your Mac can get infected, but anti-virus software will not necessarily protect you, and certainly won't protect you better than other measures you could take instead. When it comes to anti-virus software, you have to balance the benefit of an added layer of security against the liklihood of problems caused by running anti-virus software, and have to also consider the effectiveness of the anti-virus software. See my Mac Malware Guide for more details. If, after reading that, you decide that you would like to use anti-virus software as an added layer of security, use one of the programs it recommends.

  • The best way to get 5.1 sound out of Mac Pro

    Hello. I'm not sure if this is the right place to ask this, but could someone recommend me the best way to get 5.1 sound of a Mac Pro. Since I don't require hi-fi -level sound, just simple directional audio for gaming and such, I wouldn't like to pour a lot of money to this. As I see it, I'd need an external sound card, internal PCI-E soundcard or speakers that have an optical input. I would like for the cost to be in two digits, euro or dollar.
    Any suggestions about hardware?

    Once again, the issue of 5.1 w/Apple comes up.
    Here is the bottom line.
    You will only get 5.1 audio if the following conditions are true:
    - You are using the OPTICAL output on your Mac
    - You are playing a DVD with a 5.1 soundtrack
    That's it. The simple truth is, that even if you have a Z-5500 setup (like I do), you still will not get 5.1 surround in ///any/// applications other then while playing a DVD.
    There is no way to get 5.1 out of a game on a Mac Pro. No matter how much money you throw at it. The support simply is not there. It is not a software issue, it is not a driver issue. It is the game developer's issue (sort of), and it is a //lack of hardware// issue.
    The complex truth, and I will attempt to explain, isn't that simple.
    Your Mac Pro or Macbook only has a single line-out, that supports 2 channels at the maximum. Optical audio will only handle 2 channels as well- it's the same signal (in two channels) on a different medium, basically.
    All PC soundcards that support proper 5.1 (save for a select few) have //multiple// line-out jacks for Front Left/Right, Center/Sub, and Rear Left/Right (3 plugs total for 5.1). Since your Mac/Mac Pro doesn't have this, you can't hook up a 5.1 speaker set and expect true 5.1.
    You do have optical audio, however, this only works in 5.1 when a Dolby Digital signal is piped through the optical cable.
    Dolby Digital works by encoding a 5.1 signal as a data stream, sending it to a receiver, where it is decoded and played back as 5.1 stereo. DVD's have this audio pre-encoded on the disk.
    If you wanted 5.1 output from your games, they'd need to ether have the sound/audio data encoded as Dolby 5.1, or support encoding on the fly to take a 5.1 signal, encode it, and pipe it out the optical audio plug. Xbox360 does this, because they've licensed the technology from Dolby- as have the game developers.
    Unfortunately, none of the developers for Macintosh gaming have yet to include live Dolby 5.1 encoding (I think Doom 3 had a beta patch that did- I could be wrong).
    If the game doesn't support the above feature, then you only get basic 2 channel audio.
    *Do not buy a Fireface 800.*
    This is a professional audio interface (like an external soundcard). While it supports 5.1 output via 6 individual outputs, you need SPEAKERS that have +built in amplifiers+ (called a Studio Monitor). Not just one amplifier- all the speakers have it built in and take a balanced stereo input.
    You're looking at $1300 for the Fireface 800, and another $200 per speaker. This is not cheap, is not meant for gaming, and is not consumer grade equipment. It's pro audio, designed for Logic 8 and similar.
    Even if you did spend the money, trust me, I'd know... I have a 5.1 setup running through an Apogee Ensemble (a $2000 "soundcard"), and I do not get 5.1 support from Quake 4, C&C 3, or any other game. I only get 5.1 surround from my audio production in Logic 8.
    To recap, since this has been asked many times- and I don't want you wasting your money here (just trying to be helpful!)...
    *There is no simple or cost-efficient way to get 5.1 from your Mac, other then while playing a DVD movie.*
    I would highly recommend that you buy a very good pair of 2.1 speakers with a Sub woofer. Maybe even a pair that takes an optical input for audio. If you really want to spend the money to *watch a DVD in surround sound,* then you can... And it'll work wonderfully, but gaming will not give you surround sound at all.
    *Again- There are no games out that support 5.1. Just because you technically support Dolby 5.1, doesn't mean the applications are aware of it and can utilize the 5.1 surround.*
    Edit: I may have neglected to also mention that the Firewave unit will support 5.1 properly through 3 separate plugs (much like a PC soundcard does), however the only game I am aware of that supports this is Unreal Tournament 2003 for Mac (or was it 04?), with an experimental patch for 5.1 via OpenAL. Last I heard, it worked okay, but crashed occasionally.
    Most of the other games out there just don't support 5.1, period (probably due to the lack of hardware on the Mac computers from the factory).

  • Need advice on on a Mac Pro 1,1 Media Center

    I currently have a 2009 Mac Mini running as my home media center, but I recently came by a FREE Mac Pro 1,1 and have decided to repurpose it as my media center so I can migrate my Mac Mini to my bedroom TV where it will live an easy life doing nothing but run Plex Home Theater, Netflix, and EyeTV. This machine falling into my lap was also quite timely because my 4-bay Drobo is running low on available expansion and another Drobo isn't in the budget at the moment.
    This vintage mac pro is running Lion 10.7.5, has 1 old and crusty 500GB hardrive, dual x5160 processors, 4GB RAM (one stick i'm pretty sure is toast judging by the red light and the kernel panics), and the standard NVIDIA GeForce 7300 GT 256MB graphics card. It will be used primarily for the following: network storage for iphoto and itunes libraries, streaming video, Plex Media Server & Plex Home Theater, and Handbrake encoding. I also have a goal of safety of data for my movies, photos and music as this machine will supplement my current Drobo storage.
    My plans are for a 128GB SSD boot drive installed in one of the PCIe slots and then to load up all 4 of the 3.5" drive bays with WD Green hard drives. I have also ordered 4GB of replacement RAM, so upon removal of the faulty unit I will have 7GB.
    Here is where I need advice because I am not very familiar with RAID and the differences between hardware or software raid. Am I better off getting four drives of the same size and setting them up as RAID 5 (I think) using Apple's RAID utility or should I throw in three 1TB drives and then install a fourth 3TB or 4TB drive as a Time Machine backup for the other three?
    Should I upgrade the OSX to the technically unsupported latest version? Or is it not worth the trouble for this application?
    Also, is there any benefit to upgrading the graphics card to the ATI Radeon 5770? Would this yield an improved image quality? I am outputting to a Denon AV Reciever and subsequently to a 100" projection screen, if that makes a difference. I also noticed the 5770 has an HDMI port, wich would be nice, but not necessary since I can use a DVI converter and woud still need to use the optical audio out anyway.
    Much obliged for any input

    My plans are for a 128GB SSD boot drive installed in one of the PCIe slots and then to load up all 4 of the 3.5" drive bays with WD Green hard drives. I have also ordered 4GB of replacement RAM, so upon removal of the faulty unit I will have 7GB.
    PCIe cards that use or support SSD are not bootable until you get to 2008 (and that is limited too).
    Green are not suited for any form of array unless say NAS and WD RED.  Better option would be 3 x 2TB WD Blacks in a mirror, and too many people only use two drives, well 3 is much easier safer and works better. Might want to invest in www.SoftRAID.com product even.
    Best price and quality, got my 1,1 with 8 x 2GB (ideal is 4 or 8 DIMMs)
    2x2GB FBDIMM DDR2 667MHz @ $25
    http://www.amazon.com/BUFFERED-PC2-5300-FB-DIMM-APPLE-Memory/dp/B002ORUUAC/
    With price of 250GB SSD $155 I'd go with that or stick with $89 for 128GB .

  • Need help with G4 to Mac Pro Migration!

    After buying my 2.66 GHz Mac pro, i followed the instructions as to how to start up the G4 in "Target Disk Mode" for migration. Was completely useless.
    Whether clicking the button in the "Startup Disk" prefs, or holding down 'T' and restarting, i got the same results: My G4 system would restart but before anything appeared on the screen, it shut down and stayed.
    I've been searching all over these forums and doing a lot of reading and experimentation. It sound like a lot of people aren't having good luck with the migration wizard anyway.
    II did finally manage to get the Mac Pro to log onto the G4 with a cross-over cable. But i need to transfer a tremendous amount of data both from my primary account on the G4 and 3 non-boot internal drives.
    Having to go through a public folder isn't going to cut it. .MAC isn't either.
    Is there some way i can link up the two systems such that i can retrieve what i want from the G4's drives (without spending additional money).

    Efforts to make "Target Disk" mode function didn't seem to go anywhere.
    I did at last figure out how to get access to disks all disks on my G4 from my Mac Pro, however.
    For those who may need to know it required these simple steps:
    {1} I connected both systems to a hub (or DSL router in my case) via ethernet. Connecting the two machines with an ethernet crossover cable also worked, but of course my access to the internet was then unavailable.
    {2} Opened TCP/IP in Network prefs on both machines and set them up identically according to my ISP's instructions, as always, but with differing IP addresses.
    {3} Under the Services tab in Sharing preferences i checked the box to enable "Personal File Sharing"
    {4} I then chose Connect to server... {command-K} in the Finder on the Mac Pro and entered the LAN IP address of the G4.
    {5} At the login prompt i entered my G4 main account login & password information.
    {6} When the window with my G4 system's name came up and asked which disk(s) to mount, i selected all of them and clicked { Ok }.
    Presto. The G4 main drive, my 2 disk raid, my 4th disk, and my home directory all popped up on the Mac Pro Desktop.

  • Optical audio out from Mac Pro to preamp

    I want to use the optical audio out to a preamp. I am finding only very high end components. Is there anything affordable?

    Do you already own the Mac Pro and preamp? All you need is an S/PDIF cable. Easily attainable for ~$20 or so. If it's not that simple, what are you referring to as "very high end components" being all you can find?

  • Sound cutting out on Mac Pro (late 2013)

    Bit of a long one and I'm not sure if this is the right place so sorry in advance.
    For the past 2/3 weeks the sound on my new Mac Pro has been cutting out completely. It doesn't matter if headphones, external speakers or nothing is plugged into the back the sound just cuts out. It only comes back if I reboot the mac or kill 'audiocored' (as suggested by some people over on the Apple Support Forums.
    The sound would cut out when I'm using CC products and when I'm not. It would range from 3 hours of not cutting out to every 15 seconds. If it occurred when I watching a sequence or clip in Premiere it would make the playback slow to a crawl and if I was watching a video on YouTube and it would occur the video would then stop and no longer load. The cut outs are to my knowledge completely random and I'm not doing anything that I haven't done a million times before when it occurs.
    I've been contacting Apple for a while now and gone through a number of different troubleshoots (booting in safe mode, resetting the PRAM, logging in as another user) and the issue occurs on everything. The only fix I did find was if I created a new partition on the hard drive and boot into that then the sound issues don't occur.
    Which leads me to why I'm posting this... That partition didn't have any Adobe software. I then uninstalled all Adobe CC programs on the main partition and the sound issues then stopped completely. Only when it's all installed (even when they're not even open) do the sound problems occur, which leads me to believe the sound cuts are due to Adobe CC software.
    All Adobe and Apple software is up to date. I've trashed the preferences on all my Adobe software as well as clearing the cache.
    I realise this is a bit of a weird one and maybe in the wrong support forum but I'm getting to my wits end. I've got huge projects dropping very soon (with tight deadlines) that I need to work on and can't be rebooting the mac every 5 mins.
    If anyone has any suggestions on how to fix this I would be greatly appreciated.
    I'm currently toying with the idea of doing a factory reset of the computer but I worry as I know that will take some time re-downloading / installing all my software and documents.

    I have had a bit more luck it would seem.
    Turns out it wasn't and Adobe software that was causing the problem rather some faulty RAM. I took all the RAM out and then put it back in again a few seconds later (doing exactly what Apple support told me to do) and voila the sound issues were gone. Although one of the cards decided not to work any more and I was left with 12gb rather than 16gb. Have since replaced all the default RAM with a more powerful third set from a party provider and haven't had any trouble since.
    It's very strange that this problem is persisting for you even after the RAM being replaced. All I can suggest is that you keep calling Apple as their support services seem to be pretty good (for me at least).
    Sorry if this is no help at all.

  • Need advice on a new mac pro.

    Hi,
    I need to purchase a mac pro for work in final cut & after effects primarily. Apparently there is some sort of money crisis going on so "money is not an issue" doesn´t hold for me right now. I intend on getting around 16GB (+2 GB with the machine) of ram from other sources and the same with hard drives, I´ve also heard that the current standard video card ATI HD 2600 is fine as I don´t intend on using the machine for anything other than work. My question is regarding processors. For FCS & after effects, what is the real world difference in performance I´m looking at between the standard 2.8 GHz, the 3.0 & the 3.2 GHz processors? The video footage i use primarily comes off an EX1. If its a must have to get the 3.2 then I can afford it but the price hike is quite steep and I can think of other things I could use the money for (1.400€ difference). Thanks

    Hi Fran, first of all: The EX1 produces Prores-files, and editing hd video is heavy duty for any computer, considering long render times and compositing and layering. Then again, you do not need the fastest Mac pro out there to get your work done. The 2.8 with 8 GB of ram will suffice. Faster models only save you seconds in waiting for stuff to render. Start out with the standard ATi 2600. Make sure to get a couple of speedy 1TB WD Sata drives (WD10EADS), no need for expensive raids. That's a budget Mac pro that is as good as any.
    After that you just WAIT because the real progress should be in software that's yet to come: Snow Leopard and the next FCS should speed up your work noticably, considering that the current FCS isn't too multiprocessor-savvy at all. Also, FCS isn't even fully cocoa, there's a lot of old code in there (i've been told). Lastly you can always invest in a better GPU, because that's where the extra performance is shifted to.

  • Do I need antiviral software for a Mac Pro notebook

    is antiviral protection needed for a Mac Pro notebook

    WARNING: "Avast" is useless garbage that will cause you nothing but problems.
    1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
    2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
    The following caveats apply to XProtect:
    It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets (see below.)
    It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
    3. Starting with OS X 10.7.5, there has been another layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't actually been tested by Apple (unless it comes from the Mac App Store), but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. For most practical purposes, applications recognized by Gatekeeper as signed can be considered safe.
    Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
    It can easily be disabled or overridden by the user.
    A malware attacker could get control of a code-signing certificate under false pretenses, or could find some other way to evade Apple's controls.
    For more information about Gatekeeper, see this Apple Support article.
    4. Beyond XProtect and Gatekeeper, there’s no benefit, in most cases, from any other automated protection against malware. The first and best line of defense is always your own intelligence. All known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
    That means, in practice, that you never use software that comes from an untrustworthy source. How do you know whether a source is trustworthy?
    Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
    A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
    Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
    Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
    Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
    5. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was never a good idea, and Java's developers have had a lot of trouble implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style "virus" affecting OS X. Merely loading a page with malicious Java content could be harmful. Fortunately, Java on the Web is mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice.
    Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers. In Safari, this is done by unchecking the box marked Enable Java in the Security tab of the preferences dialog.
    Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a specific task, enable Java only when needed for the task and disable it immediately when done. Close all other browser windows and tabs, and don't visit any other sites while Java is active. Never enable Java on a public web page that carries third-party advertising. Use it only on well-known, password-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
    Follow these guidelines, and you’ll be practically as safe from malware as you can be.
    6. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. If you need to be able to detect Windows malware in your files, use the free software ClamXav — nothing else.
    Why shouldn't you use commercial "anti-virus" products?
    Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
    In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
    By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
    7. ClamXav doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
    ClamXav is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
    A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
    ♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
    ClamXav may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use ClamXav unless a network administrator requires you to run an anti-virus application.
    8. The greatest harm done by anti-virus software, in my opinion, is in its effect on human behavior. It does little or nothing to protect people from emerging threats, but they get a false sense of security from it, and then they may behave in ways that expose them to higher risk. Nothing can lessen the need for safe computing practices.
    9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.

  • Audio out on mac pro

    hi there, i really hope that someone can help me with this issue that i'm experiencing.
    My normal audio set up for my mac pro is to have the sound going into a denon hifi via the line out on the mack of the mac. on occasion i need to use headphones and so i plug them into the front port.
    on my previous mac, a powermac G5, the sound system prefs automatically detected the headphones and changed the output to those when they are plugged in. in the same way when i unplugged the headphones the sound reverted back to the hifi without me having to change anything.
    this is not the case with my new machine. i have to manually change the sound output in system prefs which is starting to get quite tedious. at the moment i've also got a strange situation where my sound is coming out of the hifi via line out, but the 'volume change' sound (the sort of click when you change volume on the keyboard) is coming out of the built in speaker of the mac pro.
    not sure if i'm doing something wrong or what but if anyone has any ideas i'd be really grateful.

    Apple with Audio supports Apogee, so it would be nice to looking into this, shouldn't be like this but its just the way it is, however this baby does the trick.
