I have lost my digital audio signal, can only get analog sound. Advice?

I'm looking for advice as to the best Bose input for SACD (contains 5.1 information) captured to FLAC and played back by computer (Analog Line out currently but considering adding digital out): 1. Bose Aux in 2. Bose Digital in Regarding option 1. The Bose manual states the following which makes me think that Aux is the right decision: Setting up a digital sound source Connect a DTV or DVD player's digital signal directly to the female RCA jack on the audio input cable. Connect the DVD player's analog signal output to the AUX inputs. If your Lifestyle® system receives a valid digital signal (including PCM or Dolby Digital bitstreams), this digital sound is used. If no valid digital signal is received, then your system selects the analog signal being sent to AUX, which is then processed by the Videostage® decoder for excellent home theater sound. If your digital audio source has an optical connector, you will need an adapter with an RCA (coaxial) connector. Consult your dealer or contact Bose® Regarding option 2. I've read the following (not in Bose manual): A coaxial digital audio connection is used to send S/PDIF digital audio signals between devices. It supports uncompressed PCM stereo audio as well as DTS and Dolby Digital 5.1/7.1 surround sound signals. It does not support DVD-A, SACD or high-definition audio such as DTS-HD Master Audio and Dolby TrueHD. So in summary: The Aux in is analog but processed by the Videostage® decoder. The Digital in supports 5.1 and should be cleaner/quieter being digital I expect. I'd be interested in onions from other that know for sure what's better or have done this. thanks

Digital audio refers to technology that records, stores, and reproduces sound by encoding an audio signal in digital form instead of analog form. Sound is passed through an analog-to-digital converter (ADC), and pulse-code modulation is typically used to encode it as adigital signal. A digital-to-analog converter performs the reverse process, and converts the digital signal back into an audible sound. Digital audio systems may include compression, storage, processing and transmission components. Conversion to a digital format allows convenient manipulation, storage, transmission and retrieval of an audio signal.

Be advised that the engagement of any device in a Tape Monitor loop will effectively tie the receiver down to stereo-only analog sound reproduction. I'll explain.

The connections themselves are fairly simple but it pays to understand what happens in the loop.

In general, any Line-Level external processor (EQ, dynamic range expander, etc) will go into a Tape Monitor loop on a receiver. A Tape Monitor, when engaged, sends the stereo analog signal Out to the Processor, massages it and returns it to the receiver via the Tape Monitor IN connectors to be passed on to the receiver's internal processes (volume, tone, whatever).

Old school analog stereo-only receivers consistently work this way. Newer digital and audio/video receivers introduce a couple of problems: 1) digital sound processing to simulate a variety of soundfields; 2) multiple output channels, either discrete or digitally-generated.

The latter requires that whatever signal is being processed experiences a maximum of one analog-digital-analog conversion.

EVERYTHING analog coming into the modern digital receiver is automatically converted to a digital signal for internal processing unless you choose a STEREO-only or STEREO-Direct setting. Consequently, no further external analog-digital conversions would be allowed if, say, a Tape Monitor circuit was activated, and a possible feedback loop could otherwise be created in a digital-sourced selection (output to its own input), so the unit is wired to treat the Tape Mon as the first analog step in the process and defeats any pure digital sources.

In a multichannel unit, what would happen to the other channels if you sent ONLY the Front Left & Right out for processing? That logical problem also plays into the decision to defeat digital sources if the Tape Mon is activated. I don't totally agree with the engineers but that's the way it is. Nature of the digital beast.

Okay, back to the hook-up: Receiver Tape- or VCR Out to the External Processor (EQ, whatever) Preamp-, Amp-, Tape- or Rec-In jacks; Receiver Tape- or VCR In from the External Processor (EQ, whatever) Preamp-, Amp-, Tape- or Rec-Out jacks.

If you actually want to use an analog recording deck you could place it within the typical Equalizer's own Tape Monitor loop(s). Many have two to facilitate equalized dubbing between decks.

Your audio source needs to match the signal you are receiving. On the menu go to audio and then setup My source is set to HDMI (like my video). Within that selection you have the choice of analog, digital or auto. Auto should work for all signals. Analog will not give you sound if you have a digital signal (I found out by accident).

S video connector is used only for video, you need to connect the audio separately via the RCA audio connectors or via digital coaxial or optical connector.

You can read more on S video standard here:
http://en.wikipedia.org/wiki/S-Video

Also see the related topics on audio, maybe you should consult the user manuals for your dvd unit and the amplifier that you use to get more info, but normally the sound can be connected via these connectors on the rear panel of dvd units:

- main left and right analog signal out RCA connectors (2 channel stereo signal - amplifier set to analog signal)

- main left and right, sub, center, surround left and right analog signal out connectors (multichannel surround signal - amplifier set to analog signal)

- coaxial digital signal out RCA connector (a single cable that takes the stereo or surround signal to the amplifier in a coded digital form - you need to set the amplifier to the digital signal mode to enable this kind of signal)

- optical digital signal out connector (same as the coaxial digital output, the difference is that the signal is in the form of light pulses instead of electrical pulses - the amplifier should be set to the digital signal mode as well)

Hope this helps somehow - if it doesn't, post me some feedback, perhaps a brief description of the units that you want to interconnect...

It only passes the signal it see's. Digital for Digital and Analog for Analog. Try running a Standard analog RCA from your Cable box to the receiver then try and record. Hope this helps. If you still have an issue, post a comment and I can help you further.

What do you mean by "sound programming"? -- I guess it's the ability to change the sound processing, such as from Stereo to Dolby Digital, or to Dolby Pro Logic or Virtual Surround, etc.? Maybe there's a "Direct" or "Pure" or "Tone Control Defeat" button that was pushed, which often (or always!) bypasses all the sound-processing circuits? Check the front panel and/or your remote for such a button and try that.
If it's a DVD player, it may be that the audio connections were accidently pulled or changed. Assuming it's the latter (more likely): Either the digital/analog output setting of the DVD player or the setup of the receiver could have been changed. Next, this is a guess, but most likely, it is the receiver that was tweaked -- in order to listen to some other source (such as the tuner), and it is no longer set up to process the digital signal, but stays in analog mode -- AND there's no analog audio connection from the DVD player (or it was not set-up to output analog to the receiver, since the preferred signal is digital surround). Am I getting warm?

In audio 12 bit selection, you can add audio (audio dub) without deleting or damaging original sound track. Like narrating some introduction in your voice and keeping background / original sound as well. 4 bit difference is used to add additional sound in same sound file without deleting previous audio data.
16 bit audio selection will not give you this option and audio-dub option will be disabled. If you want to add more audio, you have to over write complete sound track in movie file.
I'm not sure that I conveyed it to you correctly. Need further info, let me know.

Hi - Please check the setup of the digital inputs as per pages 11, 20. 21 & 37 in the manual.

Most important:



Are you using coax or optical connections? Even if you have not moved them you should check they are securely fitted as they can work themselves out in time.

Let me know how you get on.

Best regards,
Informatica.

That output only works with digital signals (digital tv channels and digital audio from the hdmi in jack).
The HDLCD2600 has no analog out. Sorry.
