Is MBP optical input stereo?

Hello. I'm a newb when it comes to digital/optical audio and TOSLINK cables. I've got a digital recording interface that has an optical TOSLINK output. The device has two separate preamps/channels and I would like to record them simultaneously into my MBP, yet record each of them to independent tracks in Logic Pro.
My question is, is the optical signal MONO or STEREO? The device I'm using is a Korg TP-2, and I can't seem to find any info on if its a stereo output signal.
I have used a mixing board and the audio input on my mac(s) in the past to record two separate channels by panning the channels (1) LEFT and (2) RIGHT.
I would love it if I could do something similar with this device. If its just a blended MONO signal, I couldn't see investing in a TOSLINK cable and suitable adapter.
THANKS

Ok, I understand what you were saying about the two rings ON the connector. I wont be dealing with RCA cables anyway.
So one Toslink cable and a MiniJack adapter is all I need. And am I correct to assume then, that the MiniJack connector need not be "stereo" because it is a digital transfer and all the needed info will be transmitted? It will appear to resemble a mono Mini jack end?

HT2646 Is it possible to plug apple tv into my stereo sound system which does not have digital optical input

I have recently bought Apple tv. It works fine but I would like to run it through my sound system which is an older stereo system and does not have an optical digital input. Is there any other way of running apple tv through these older sound systems which do not have an optical input?

The easiest way is to connect your television's analog audio output to your stereo; since the television is now doing the digital-to-analog audio conversion, audio/video synchronization is preserved. Note that you may have to enable the analog audio output somewhere in your televsion's setup menus; this varies by TV model.

Powered Speakers with Digital Optical Input

Looking for a stereo pair of powered speakers with optical input for use with the MBP. I am not interested in a sub/satellite or 5.1 set-up, just a stereo pair for now. Anyone find any ?

Well, Google found I think what you were mentioning:

Optical Input Problem

I checked system preferences, and it looks like it is recognizing the input as "Optical digital-in port." When I unplug the mini-toslink cable, it goes away. I am also getting the red light, so I am getting information through the cable. When I plug the cable into my receiver, I can get audio through my stereo. So the audio source is working.
However, I cannot get the optical input to work on my Macbook Pro. Can't get digital audio through Garageband OR Audio Hijack Pro. Am I missing something here? Keep in mind I am new to the Mac, so please feel free to make fun of a newbie like me.

I am also going to try the optical out to see if my receiver can receive info from my Macbook Pro...

Optical Input on Creative Labs Sound Blaster X-Fi Xtreme Audio PCI-E with Logitech z-5

So i plugged in my Optical cord into my new sound card the Creative Labs Sound Blaster X-Fi Xtreme Audio PCI-E and it worked only in the Front right, Front left, Front centre, and the subwoofer. Now i hear i need a external decoder... but then again that my sound card should decode it as well... the place i bought my card recemended a optical cord for my card?with the?speakers i have?(the?Logitech Z-5500) How much are decoders? What should i do next? Creative seams to have limited support especialy on optical inputs.

I must have answered something like that in another thread sometime ago, but here goes:
A single SPDIF connection, optical or coaxial, will only transfer stereo in analog form; no rear or centre channels!
There are two ways you can get all speakers playing via such a connection:
() Get your speakers to upmix the audio source to play on all fi've of them
(2) Output a Dolby Digital (AC3) or DTS signal. These contain the multichannel information encoded in the stereo signal. A suitable decoder (such as the one contained in the Z-5500) will be able to analyze the signal. Unfortunately, this is something you can mostly find in movies.
So, to sum it up, no natural everyday multichannel sound over one SPDIF (e.g. no EAX, directsound3d etc.)

Digital Audio Optical Input S/PDIF on Mac Mini 10.9.2

For years prior, with my MMP 15", etc. and since the fall the Mac Mini (fall '13), the setup worked flawlessly ... until recently -- since around the time updating to 10.9.2 I have had intermittant issues with the digital I/O with my Apogee Rosetta 200 until it stopped all together last week.
I have replaced or swapped out the cables first off, to no improvement -- I called Apogee and we were able to prove the input to Apogee with an Eventide Esclipse's S/PDIF output.
I called Apple and the tech and I rebooted in safemode and saw the Audio Devices pane of Audio Midi Setup and Sound neither showed the digital input/output as being active. I sent the unit in and the logic board was replaced in view of the circumstances.
I just setup the repaired unit and now the S/PDIF out (from the Mini to the Rosetta) works -- the Sound pane shows that shows the functioning digital input however, and conspicuosly, the Audio/Midi does not (and used to).
Further, the S/PDIF in (from the Apogee to the Mac) is neither functioning nor the two panes, Audio devices and Sound, register the digial input.
Is there an issue with 10.9.2 or is it possible the one of the 1/8" analog/light pipe inputs of the Mac Mini is also not working and not determined/checked duri -- other ideas?
I have a backgorund as a Mac tech and a member of Apple Solutions Expert since back in the 90's ...

The optical digital audio input is a good way to get basic digital audio data into the Mac - assuming you have the audio in that format. Most vinyl digitizing folks do not.
The most common hardware configuration is to use your old vinyl turntable, connected to the proper phono input of a stereo (most modern stereos do not have this and you have to buy an outboard phono preamp). Then the recording (tape) output of the stereo goes to an audio interface that connects to the Mac with Firewire or USB, and not using the Mac optical input at all. There are dozens of famous makers of interfaces from a hundred dollars to thousands. For the casual user, I'd say $250 is a nice spot. You can get a stereo interface that takes analog input from your stereo, digitizes it, and send it to the Mac. It will also accept microphones, should you want. You'll need software to record and edit the audio (Audacity is free and works) and you can use iTunes to make CDs (although cumbersome).
There are interfaces that do have optical outputs that you could connect to the Mac. But since optical interfaces are rare on computers, and have many limitations, this isn't so common.
There are many tutorials on the net about digitizing LPs on computers.

Airport Express connected to optical input on receiver, but no audio

I have a Rotel RSX-1055 receiver. I recently bought a toslink cable to connect my Apple Airport Express to the optical input. The receiver seems to be getting a signal - 44.1 khz scrolls across the display when I play music - but I'm getting no audio.
I'm streaming VBR MP3 files converted from CDs using LAME on a high quality setting. I can't seem to find any reason why this isn't working.
Any advice would be greatly appreciated.

Hello rjpwp001. Welcome to the Apple Discussions!
I suggest trying the following:
o Connect a pair of stereo headphones to the AX's audio port. Does the audio stream play thru the headphones properly? If it does, this should verify the analog audio circuitry is functioning.
o Try a different audio source, like iTunes. While connected to the receiver with the TOSlink cable, try different audio selections from iTunes. Are you getting sound at the receiver now?
o Try a different TOSlink cable. How about now?

Digital Audio Optical Input S/PDIF cable recommendation

I have a 2010 iMac. I am beginning to research a project for my mom that involves converting old recordings a group my dad was in years ago to digital from vinyl. I have a couple of input options available but I'm seeing reference to optical input on the iMacs. It appears that this would give me the best audio quality. So, my question is this: To go from a pre-amp output, what cables, converters, et cetera would I need to in order to make use of the optical input for audio? I have looked through the forums and see some mention of the subject, but nothing that seems directly to address the specifics of this.
Thank you.

SB X-Fi Titanium and SPDIF Optical input: no input sound

I'm attempting to use my SPDIF Optical input for the first time on my Windows 7 PC. Audio input works fine. No sound appears to be coming in through the optical input. Sound Properties in Control Panel shows everything is OK.
I am using a Converter box to convert a Coax optical output of my Boss GT-6 Guitar efx unit into a Toslink cable input. Everything is plugged in correctly. So assuming that the converter box and cable are doing their job, what subtle issue should I be looking for regarding input sound on the SB card? Everything looks OK, but still no sound.
I do get a low-level hum from my speakers when I turn on my GT-6 and it goes away when the GT-6 is powered off. At least something is being detected. I'm unclear how to proceed troubleshooting this
Thanks for any assistance...Mark

I've been going through the same headaches with my extreme gamer. I wanted the quality of an optical connection and was impressed with the improved clarity and gain, but as frustrated that no 5. seemed possible on anything other then dvd's.
A extreme GAMER card should have GAME support one would think. Then I read about the Dolby Digital Li've Pack, avalible here at the web site, For a fee of course ^&%$&(.
It convert ALL sound from your card, even stereo if you use the CMSS-3D settings, to Dolby so any reciever can now decode them via an optical cable.
The only issue I'm having is that with Dolby Digital Li've enabled I'm getting a few millisecond delay that is slightly throwing off the lip syncing while playing video, I can't seem to find out why, with the DDL unticked the delay is gone, but so is the 5..
I'm not sure if it is because the DDL works in real-time and that causes the slight delay, or not. It isn't a huge problem just a annoying one.
It seems that Creative sucks at digital, lol. Or just doesn't care very much about it.

I would like to connect my Apple TV to my receiver using an HDMI cable and pass thru dolby digital. I do not have optical inputs on my receiver.

I want to connect my Apple TV to my receiver using an HDMI cable. This should allow me to pass thru high definition video and simultaneously decode Dolby Digital material with an HDMI connection from my receiver to my TV without the use of an optical cable (my receiver does not have an optical input). I am unable to decode 5.1 material and don't understand why this is not working. In the audio setting I have Dolby Digital output turned on.

Welcome to the Apple Community.
Are you sure the content you are playing has Dolby Digital.

How do I use optical input for recording in Garageband 9?

Hi,
I'm trying to use the Optical Line Input on my G5 for recording in Garageband, using a MOTU 828. I have the 828 optical output connected to the optical audio input on the G5, and I have Digital In (Optical digital-in port) selected in system preferences/sound. But in Garageband preferences, optical or digital input is not among my choices. If I select system setting or built-in audio 2, I get no signal. If I select MOTU 828, it defaults to the analog master outputs on the 828.
I am a Logic 8 user, and I'm able to select the optical input in Logic with no problem. I have my MOTU audio setup set so that the optical output is the default output, but Garageband still seems to use the analog output. I can tell by the record level, which is considerably louder for analog than for optical.
Any suggestions?
Thanks!

Optical inputs on Audigy 2 ZS Platinum

I'm considering purchasing the Audigy 2 ZS Platinum Pro and I have a question about the optical input functions on the external control box. I read that it can be used to capture music(i.e. from a guitar, etc) however I would be interested in using the optical input coming in from a stand alone DVD player or PlayStation 2. By doing this, would my speakers play the audio? In other words, will the optical inputs take the signal from an external device and process it into surround sound, AC3. I read that some other models will not, so thats why I'm asking.
Thanks in advance for any help!

I run my xbox and xbox 360 to the optical in with good results so im sure the out would give similar results.
So im gonna say yes, but im not sure.

How can I input stereo audio to a iMac late 2012?

I can't wee where I can input stereo audio to my iMac (lat 2012) so that I can save the digitized audio to the music library.

I have one of these (iMic)... Sometimes I need to get a song off of a cassette and this does the job.
USB Audio Interface: iMic lets Mac and PC users add stereo input and output to USB computers — even computers that lack audio-in or -out ports.

Can't get optical input to w

I have my XBox hooked up through my Audigy 2 Platinum Pro, and I was wanting to route the sound signal to my speaker system. I have the optical cord plugged into the Xbox output and into the Platinum Pro input, I have set the XBox up through the bios to output Dolby Digital and DTS and such. And I checked to make sure that the optical input wasn't muted or anything, and it isn't... but I don't get any sound from the XBox from this setup, and I don't know why. What do I need to do? (I have a 7. Speaker System also)

Does anyone know of a mini sterio with surround sound and optical input in Mac Mini form factor?

Does anyone know of a mini sterio with surround sound and optical input in Mac Mini form factor?
I use a Mini as the family media center and would like to have 5.1 or 7.1 sound for films but don't want a huge piece of eletronic equipment (I have one of those, but it isn't hooked up because it doesn't fit on the bookshelf). Years ago I used a PC and still use the Creative Audigy speaker system (Jimmy rigged to the Mini) that I ran from the PC. The Audigy PCI sound card obviously doesn't work on the Mini, so I just have two chanel plus sub. That has been fine since I switched to the Mini in 2007, but am updating to a new Mini in the summer and would like to upgrade my sound as well.
I also wouldn't be opposed to a USB soundcard that can drive the speakers. In fact, my wife would prefer smaller and less visible, ergo USB card hidden in the back.
Suggestions?

Hello John, I figured it was a signal issue. All the speakers fire and the sound is great. I was running the speakers thru a Dell PC with a Creative X-Fi Elite Pro, THX Certified, 7.1 soundcard using a fiber optic from the Mac Pro to the Z906's, it worked great until the Dell died!!! When I bought the soundcard from Creative I also bought the GigaWorks S750, THX Certified, 700 watt, 7.1 speaker system, used the speakers for 11 years and then the woofer/amp said "I QUIT" Creative quit making the speaker system and the sound card. The satellite speakers from the Creative GigaWorks speaker system still sound great (rated at 78 watt each) and are a little better speaker than the one's that came with the Z906 and the wattage from the 906 is sufficient to drive the satellites without any distortion. Thank you for addressing my issue, you confirmed what I suspected all along, just needed to hear it from someone with the same setup.
One last question, I purchased a Diamond Multimedia USB Soundcard, can't use the fiber optic(not supported by Mac) but the green, tan and black RCA's plug in and produces adequetly. When you plug your 906's into the Mac Pro using the fiber optic how do you set your speaker configuration? When I plug into the mac pro with fiber optic the 'Audio Midi Setup' does not seem to see the 5.1 configuration. Any thoughts there?
