Digital vs Analog audio meters

hi,
so i'm dumping from final cut to a digital betacam tape and wanted to know if anyone has a rule of thumb when setting your sound levels on the deck compared to the bars and tone's level in final cut.
thanks.

Is this a trick question?
Digital Betacam format supports four channels of 20-bit/48kHz digital audio.
If on the other hand you want to know about outputting digital audio to analog then there are digital levels used to correspond to 0 dB on an analog meter:
1. –12 dBFS: This level is often used for 16-bit audio such as DV audio, and for projects
with compressed dynamic ranges, such as those for television or radio.
2. –18 or –20 dBFS: This level is more common on projects with higher dynamic range,
such as professional post-production workflows using 20- or 24-bit audio.

Optical digital and analog audio out

I just purchased a Pavilion 500-214 with IDT High Def Audio CODEC / DTS Sound+
Is it possible to get both opitcal digital audio out and analog (speakers/headphones) out at same time? Stereo amp needs access to both for multizone/source function. I can manually pick one or the other before playback - it is clunky in that when switching audio out devices the active will turn off but one switching to does not always turn on. But i really need both simultaneously active for amp to work properly. I have also found rear speaker jack to be more stubborn during switching than front headphone jack.
This question was solved.

Hi zombi1,
Welcome to the HP Forums!
I have done some research on whether or not one can utilize both digital or analogue audio out at the same time, and unfortunately this is not possible.
Thank you for posting, and Happy Earth Day!

Apple TV great on older DVI TV w/ simple digital to analog audio converter

I bought a Digital to Analog Converter (DAC) for $59.95 to convert optical audio (via Toslink) to RCA analog stereo jacks.
Device I purchased was a DAC-2016 S/PDIF to Analog RCA cnvt.
Very compact!
Also, bought a Belkin Toslink cable for $19.95 at the local Apple Store.
Works perfectly with my HDTV that only has DVI and Component inputs (plus coax, component, etc.)
I just bought it last month.
Googled it a minute ago. Price seems to have gone back up to $89.95. (List price is $99.95.) Not available right now. Maybe Apple TV caused it to sell out.
Let me know if any of you can find this item in stock anywhere or have another solution. I have a friend who has an older HDTV with DVI inputs.
Thanks,
Alan

Finally realized that it was the Gefen box not working!?!?!? I went to the store and asked them to try it out and they had trouble too. Another Gefen was tried and it worked. They all said they had never seen a defective one before. Thanks anyway for your help. It was appreciated!

Monoprice TOS digital to analog audio converter...

does NOT work with a split optical signal. Signal is too weak for the converter to do the job. (Previous posting about this in pre-release forum is no longer available).
Best bet is to use a TOS optical switch instead of a splitter to ensure that the optical signal is not attenuated:

Even better, for those who need to connect ATV2 to receiver via both analog and digital audio input to enable multi zone support (Denon receivers) here is the best solution that does not require a splitter or a switch:
http://www.ambery.com/aldiaufoco.html
This device will pass-through the TOSlink optical signal while simultaneously converting and sending analog decoded audio signal. A bit pricey, but this seems to be the best no-hassle single-box elegant solution.

32" Toshiba Regza - can i used digital to analog optical audio converter?

32AV700A - 32" Toshiba Regza
Can I use digital to analog optical audio converter?
My objective is not to use LCD TV internal speakers as it's really bad since the the speakers are on the back. If i use the digital optical cable and plug in to the converter, can all my DVD and other devices connected to the LCD TV play to 1 external audio source instead internal speakers?

Thanks for the suggestion.
I got a bit more noise but still no coherent sound.
What next?

Analog Audio Output Jack for Digital Speakers with same jack configuration

I just purchased my first Mac, a Mac Pro. I can't get sound to my speakers using the analog out jack. With my old PC, there was a setting for "digital output" even though the digital speakers were attached via to the same style jack as the Mac's analog out jack. I've tried going to preferences but don't see a like setting for digital output. Is there a setting to do so and if not, is there an adapter to convert the Mac's digital audio out to the analog jack style?

Do you want digital or analog? Your question seems to imply that you have speakers that accept a digital signal but you also say you want analog...??
Anyway, my Mac Pro (2006 model) has separate analog and optical digital outputs on the back. The pictures on the apple website still show the same thing on the Mac Pro so I'm guessing it's the same. I think only the Mac laptops have the analog/optical digital combo jacks...
The optical digital outputs are the little white squarish ports beneath the rear firewire ports.
The MacPro does not have a SPDIF RCA style output. Maybe that is what you are thinking of from the windoze pc...
You should be able to enable the rear analog line output or the digital outputs from the System Preferences > Sound > Output screen. The front headphone outputs kind of act weird in that they disable the rear line output (if I remember correctly, I never use the front port...).

Apple TV2 missing analog audio output for multi-zone system

Found out the hard way that most receivers can't support digital audio in multiple zones (i.e., Zone 2). Since Apple TV2 (ATV2) dispensed with any analog output, if you have a whole-house system that depends on mult-zone to distribute audio to various speakers, you won't be able to use ATV2 to stream music to anything other than Zone 1. The only outputs are HDMI and optical (both digital audio). I think I found a work around (which, of course costs more money) which is a "de-embedding" device from Atlona that takes HDMI in and splits out the audio to analog and passes the HDMI through to the receiver. The analog audio output then lets me connect to the analog in on the receiver so it can stream to all zones. I figure Apple just didn't have enough real estate on the new product to make room for analog, but it's a pain. Hope this helps someone. If anyone knows a better work-around, I'd love to hear it.

I have the same issue with a MacMini I use for music. My solution was to use an inexpensive optical splitter - one feed to the optical input of my receiver and the second to a DAC. Then run standard RCA audio cables from the DAC to the analog Zone 2 inputs.
Here is a link for a DAC
http://www.monoprice.com/products/product.asp?cid=104&cp_id=10423&cs_id=1042302&pid=6884&seq=1&format=2
They should have the splitter as well.

AppleTV audio out to old amp with only analog audio

I'm thinking about getting the Apple TV for both video and for playing my music on my home stereo system. I currently have an old amp with only analog audio capabilities, but the new ATV looks like it only supports digital optical out, and the digital to analog converters I've looked for seem pretty expensive. How can I get the audio from my music collection (iTunes) to play wirelessly through ATV through my amp?
I currently also have an Airport Express which I use for audio, but I was thinking of selling that and just using the ATV since the ATV can essentially do the same thing as the AX with added video benefit. I've seen some threads on streaming audio from the ATV to the AX, but do I really need both? Seems like there should be another way.
I was thinking of connecting the ATV to my TV via HDMI cable for audio, and then using an analog audio out from the TV to my amp. But, if I'm correct, that would only provide me with sound coming from the TV. It wouldn't give sound out from iTunes, for example. Is that right?
Are there any other options?

Followings are my observations in audio streaming with Apple TV 3 and Airport Express through AirPlay protocol:
-- Apple TV 3 come with only digital audio outputs through HDMI and optical SPDIF outputs. If you connect optical link from the optical output to optical input of any DAC and HDMI cable from the HDMI output to HDMI input on TV set, audio output will be transmitted through both digital outputs. Thus is is not necessary to turn on TV set unless visual feedback is required. There is no audio analog line output for Apple TV 3.
-- AirportExpress come with single combo mini jack (digital + analog) for audio output regardless of old/new models. You can connect either digital optical link (with Mini/Toslink adaptor) to digital input of DAC or analog line cable (inferior) to analog line input of amplifier. When analog line is used, digital-to-analog conversion is done by DAC built into AirportExpress for which do not expect quality is as good as most external DAC models. What do you expect from a single-chip DAC implementation vs standalone DAC models cost few thousand dollars ? Moreover analog line is susceptible to interference more than digital line.
So the decision to use Apple TV or AirportExpress, analog or digital transmission for audio streaming depends on whether you need WiFi base station features of AirportExpress to establish wireless network and quality of your audio system to justify all-digital audio transmission. Followings are what I use in audio streaming from iMac/iPad mini /iPhone 5 to audio system in living room. Quality of audio output is comparable with Sonos Zone Player as audio source.

Optical Audio - Analog Audio Adapter?

I have been thinking for a while about buying an Apple TV.
One of the main reasons I want an Apple TV is for streaming music through the Apple TV into my stereo system WITHOUT having the TV turned on.
So this means I need to use the Optical Audio port to go straight into the stereo.
I have a Kenwood XD-551 stereo system which is reasonably old and only has Analog Audio input. That means I can't connect an Apple TV to the stereo using an optical audio cable. Is there an adapter I can buy that connects Optical Audio to Analog Audio?
I know I can stream music to the speakers through an AirPort Express (I have a 3.5mm to Analog cable), but I want an Apple TV also to stream HD Movies and TV Shows from iTunes, as well as AirPlay Mirroring from my iPod Touch.
My current set up:
TV --- 3.5mm jack to Analog Audio Input --- Stereo
My intended setup:
Apple TV --- HDMI --- TV
Apple TV --- Optical Audio to Analog Audio Input --- Stereo
I REALLY NEED A SOLUTION TO THIS OR ELSE I MAY NOT END UP BUYING AN APPLE TV

I am also looking for a exactly a similar setup.
streaming music through the Apple TV into my stereo system WITHOUT having the TV turned on
@alexei Ok, so this solution works with you. just to understand the setup,
you connected the apple tv's 'optical digital-audio port' to a DAC using which kind of cable ? links from amazon or other websites will be very useful.
Output from this DAC, you connected to the speaker via 3.5mm jack, correct? again a cable name (both ends) will be extreemly helpful.
With this when you airplayed music on 'apple tv' via itunes just the audio played on your speaker, correct? assuming your TV turned off during the music play.
And when you airplayed video/movies on 'apple tv' it automatically played on your TV.
Just wanted to know, you see only one airplay configured on your iphone/ipad correct ?
If this exact setup works with you..then bingo..I can go ahead buy all those stuff. If you have a different set-up with which you play music and video sepeartely using apple tv then please do share..
Your answers to these quesions will help me to decide if I need to buy Apple TV for music(which is equally important) and watching movies. And the invetsment dosent stop there..therz DAC and cables.
Thanks!
PS: I know I can stream music to the speakers through an AirPort Express, but want to go for apple tv.

Connecting 5700 with laptops' only digital AND analog output

Hi everyone!
Although I'm an experienced creative user this is the first time I'm posting. I looked trough the forums but I couldn't find any answer to my question and I hope this is not the "n"th time it is asked...
I have Inspire 5700 Digital speakers and I recently bought a Sony VAIO VGN-FES laptop, with an Intel 945PM Express chipset, which features Intel HD audio. In the sound setup utility of Sigmatel HD audio, there is even an option to enable digital SPDIF output, which I enabled. But when I connect the digital din cable to my laptops only output jack (headphones...) I have no sound at all...
I thought that it may be due to the fact that the jack is not digital only. But I still want to have real digital 5.1 audio. So could anyone tell me how I can do that?
Thanks beforehand!

Addlclove,
in the sony forums the answer I recieved was that the headphone jack was normally 2.1 analog, but I didn't receive a fulfilling answer to my query about the reason to the spdif setting in the setup utility and the chipsets features. That's why I came here The only output I have on the computer is the one for the headpohes. But there is a docking station that I could buy, having an optical out.
And Jason-CL,
You're right, I used to have an Audigy, and I understand that you're saying that I can't do it through the headphone jack, right?

How to get audio meters in capture in Premiere CC?

I need to capture in Premiere CC from an old tape machine that outputs in S-Video. Audio comes in through a Matrox I/O.
Picture comes in fine but I do not see capture audio meters to adjust the sound. In Adobe CS6 I do get the audio metering.
Is there a way to get the audio meter in CC?

You dont modulate on capture. (digitising) eg analogue to digital.
You do that once in the system if need be.

How do I get analog audio from my apple TV 2nd generation?

I am trying to find a solution to getting an analog (RCA stereo) audio output from my 2nd gen AppleTV to my Onkyo receiver so that I can listen to audio from it on my "B" (outdoor zone 2) speakers. Unfortunately the receiver only accepts anaLog input for the zone 2 speakers. The 2nd generation AppleTV only outputs digital audio. Kind of a pickle. The only solution I've found so far is a pricey digital to analog converter that costs more than the ATV! I have no idea if this will even work, or still output sound through the HDMI cable at the same time.
Anyone out there have any advice or suggestions? Any and all help would be most appreciated as Apple tech support can be very unhelpful without paying for the support plan.
Thanks,
Brian

Thanks so much for the quick responses! I've just ordered a DAC from B&H made by Gefen that should do the job. I opted not to get the one that decodes Dolby Digital as I only intend to listen to music on my Zone 2 speakers that are located outside on the back porch. However they do make one that would be great for those needing DD decoding, and I am told they corrected the popping sound when changes sources or channels.
I could have bought a much more expensive receiver, but I feel that a have a stellar system that is up to date with almost all of the new technology. This will all change in 5 years I am sure! At least for now I am all hooked up with HDMI and am receiving the best in picture and sound, with the exception of my "B" speakers being analog. No biggie.
I'm pretty happy with my Apple TV2 with except for the occasional wi-fi glitch and the lack of Pandora.
Thanks again for the replies!

Stereo line-level analog audio input?

The analog audio input on my machine seems to be mono only. If I put in a stereo line-level signal it just duplicates the left channel on the right. Is there any way to input a stereo line-level signal through this jack?
ALFRED GUZZETTI

The input source is a DV tape deck. At the head of finished tapes I record bars and tone. The first segment of the tone is on both channels. It is followed by tone on the left channel only, then the right channel only. When I monitor what the computer is getting either through headphones or direct the input to Soundtrack Pro, where the meters display left and right, I hear and see sound on both channels from both the stereo input and the left-channel input (which shows up on both channels in the computer). The right channel only input is not audible or visible on the meter. The computer has always been this way. I assumed, maybe wrongly, that the input uses a stereo jack since these are pretty universal, but that in effect, the input is mono.

Analog Audio into Macbook Pro Audio Port

I'm trying to pass an analog audio music signal from an external recorder thru my mac pro.
Preferences settings are:
Input- audio port
Output-internal speakers
Signal is hitting the computer and registering on the input level indicator as being received but it is not being delivered by the internal speakers.
The signal from the external recorder has been verified by myself via the use of a set of headphones.
Apple Care expert technicians insist that a driver should be provided by the external device (which to me is rediculous) however I called them the device mfr.to check which resulted in nothing being available, as I expected.
Is the mac manual correct that a line level mic. (which I interpret as being an alalog signal) should work with my Mac??

I don't know what the Apple manual you're referring to says on the subject, but I doubt that LineIn is performing an analog-to-digital conversion, since the speakers need an analog signal.
And I don't think LineIn provides any amplification, either. It just enables a software path from the audio input to the speakers that isn't there otherwise. If your speaker volume is acceptable, then the signal you're inputting is already preamplified (= line-level).
But I'm no audio professional, and I could be wrong about any of this. All I really knew was that LineIn would serve your needs if your incoming signal was suitable, as it apparently was.
