SOURCE: Onkyo TX-DS939 optical selection problem help!

That coaxial, opt-1 and opt-2 are available only if they are not selected to some other channel. So you have to check if opt-2 is selected to Video-1,2,3,4,5,6,7,CD or DAT. Change that to Analog and then opt-2 is free to another device.

SOURCE: listening modes not working??

I am a little hesitant to tell you what this is because sometimes people give bad ratings to an expert when they do not get the answer they want to hear. I will take a chance here and assume you are a reasonable person and tell you what the most likely cause is. I have been reparing these type of receivers for as long as they have been making them, and every time I see this particular problem it is always something on the digital board. This is the board the the optical and coax inputs go into on the back. They also run all the audio thru this board, and when you only get the audio that you have, a problem is going to be found there. There is some good news and some bad news that goes with this, first the good news. Many times (about half), the digital board only needs to have some of the solder reflowed on a few of the IC's and it will return to normal operation. If this is the problem your repair should only cost from $90 to $150 depending on the rates of the shop. Now the bad news, if the board has a couple of bad compnents on it, it will need to be replaced. The reason that is bad news, is because those boards are very expensive, usually over $250 just for the board, if the board is even available. Many of these receivers you can not get the digital board for them. Most all of audio equipment is component level repair and there are not many technicians who can troubleshoot these boards, they are a very difficult task.

I hope this free information was helpful, and if so a "FixYa!" would be the appropriate rating. You do not need to have your receiver fixed in order to give a good rating, only that you are given the correct information.

Let me know if I can be of any more help to you, good luck with your Onkyo.

SOURCE: Source always PCM, can't get Dolby-D

PCM is standard when using HDMI cables, you are passing an already decoded audio signal to the receiver and it outputs the sound and does nothing more. The reciever calls this PCM, your PS3, when pressing select should show that it is decoding the dolby digital HD. There is no quality difference in the two. PCM is the same because it is un compressed audio. So when using HDMI, no matter the signal that the movie or music is playing, wether it be dolby or DTS, you will see PCM when using HDMI.

SOURCE: I have an Onkyo 606 Receiver which is now about 6

q-tip and RUBBING ALCOHOL (anything else will damage the connection) very carefully clean out the input. then use a vaccum on low setting and place it over the input and pull out whatever debris is left. repeat if need be. In the future if you want to protect any connection on the avr or any component you may have place a piece of tape over the input to keep dirt or dust out. the q-tip and rubbing will clean up the tape when you go to use that particular connection.Home theater has been my hobby since 1993,the above is what I know to work.hope this helps you.

Wire Kenwood GE 7030 equilizer to onkyo tx sr504 receiver


The manuals explain it.

http://www.retrevo.com/support/Kenwood-GE-7030-manual/id/479dj189/t/2/

http://www.retrevo.com/support/Onkyo-TX-SR504-Receivers-manual/id/365ag215/t/2/

For all practical purposes an EQ or any analog audio processor connects exactly like a Tape Deck - into any RCA pairing that has both an OUT and an IN and can be selected to be in or out of the audio path.

However, on this and just about any modern digital-capable AV Receiver, activation of any external loop that would connect a processor or tape deck would automatically DISable any digital audio sources. The effects of the processor, therefore, can only be used with analog stereo sources. It WILL affect the sound going to all speakers if you use the various Digital Sound Porcessing modes as the extra channels are derived from the stereo channels anyway.

Tx-sr575 7.1 - is there any use in connecting and old power amp and equalizer to this receiver? If so, how?


Ya mean like to hook up Bose 901's? Nevermind.

Utility is in the imagination of the dreamer.

http://www.retrevo.com/support/Onkyo-TX-SR575-Receivers-manual/id/2526bh749/t/2/

Any analog processor can occupy the Tape Out/In loop. However, it will only affect stereo analog sources and, once engaged to monitor, it will disable any digital audio source.

An external amp COULD be slaved off the tape Out (or the anticipated EQ Out, but it won't be volume-controlled by the Onkyo. You would need an AVR with at least Front L/R pre-outs.

[TX-DS595] My Video 1 stopped working, no audio, (Right before the super bowl!) yet I get audio on DVD & Tuner. What could be the problem? Thanks, Ira S. Cohen


Well, what's on Video 1 and is IT okay?

You don't say if you're using the analog audio associated with Vid 1 or if you have digital audio coming in and assigned to Vid 1. Check the cables. If using the optical, make sure it has no small-radius bends.

If analog audio, try another input - video 2 or 3.

If you have Cable/SAT TV as the source, what's going on with ITS audio settings?

http://www.retrevo.com/support/Onkyo-TX-DS595-Receivers-manual/id/365dj195/t/2/

You can always run that RCA cable pair from the source to theTV as a test for audio, too.

I have an onkyo tx sr608 7.1 receiver and I want to hook up my yahama eq. I dont have a tape/monitor loop, how do I do it?


Actually the VCR/DVR is a Tape Loop that would support the EQ or any other audio processor..

http://www.retrevo.com/support/Onkyo-TX-SR608-Receivers-manual/id/23653ag916/t/2/


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; Receiver Tape- or VCR In from the External Processor (EQ, whatever) Preamp-, Amp-, Tape- or Rec-Out.

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.

I have a tx-sv454 reciever and i need to know how to hookup my pioneer dynamic expander ex-9000 and a pioneer dynamic processor rg-60 and my cd player all together


I can't find an image of the rear panel but I have a low-rez manual for the TX-SV434, which should be pretty close. I can't make out the labeling on the RCA connections.

Let's simplify this. The CD just goes into the CD input.

You can either use the two (if present) Tape or Video In/Out loops for the individual processors, or you can run them in series with each other on one Tape Loop.

I don't imagine you really want to use both Dynaic Range processors together, so each one's Bypass function would take it out of the path if so desired.

The following is some boilerplate I made up that should explain some usage limitations.

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

[Or you could obtain a dbx Program Route Selector (check eBay, I highly recommend the 400x, of which I have two) and it would, while only using one receiver Tape Loop, allow for three discrete attachment paths for processors and three for tape decks with the added flexibility of front-panel selection of any and all, with the processors being before, after or between the source or tape decks. Plus it has a dedicated facility for an inline dbx Noise Reduction Processor that can also be juggled around via pushbuttons. Pretty neat.]

I have a Onkyo TX-SR604 Receiver. I get no sound


Hello Fixya customer,

Thank you for your question.

A point to keep in mind here is that Zone II will only feed through an analog source. Since the Video 1 input is using the digital (coax, optical) input that that is your most likely issue.

Thank you for using Fixya, and please let me know if I can firther assist.

Harmon/Karden AVR 230 Surround Sound Receiver


Use your remote to get into the Menu. Look for something called audio, or audio properties. In there you can choose your inputs (sources) and output choices.

On the remote itself, there should be a button called input, or source. That would be for things input to the TV.....such as dvd, vcr.

No sound using digital coaxial connections


Couple of possibilities:
Press Audio Select on front of unit until "Analog" changes to "coax/opt"

or

When you select the component connected to the MULTI CH INPUT jacks as the input source (see page 38), this unit automatically
turns off the digital sound field processor, and you cannot select sound field programs.
