No audio input from video modes

First of all, you don't identifiy the hardware.

Second, DVD 6 CH INPUT is analog so how would the device KNOW if all 6 channels are present? ONLY a device with the required 6 analog channels should be connected there. That input typically bypasses ALL internal digital processing.

Elaborate more on the digital source(s) that are failing and assure us you have looked at/exhausted what the manual says for setting them up.

You're guessing. That is exactly the wrong thing to do. Get the manual.

"[D]vd 6 channel input" is for a 6-channel analog input as the name implies. I doubt you even have a source that HAS 6 analog channel outputs.

Speakers are OUTPUTS of the amplifers' speaker posts. Any one can work ANYwhere.

And that bi-wire capability, IF the speakers have it - pretend it isn't there.

It would help to know what other electronics (receiver, maybe?) is involved.

If neither of those devices is a recorder, why do you need to connect them to the EQ when your receiver/preamp may have the facilities to connect the two playback devices directly; and the EQ in a Tape Loop?

Scenario A)

Assuming you REALLY want to have the CD and MD input through the EQ because you can't attach them any other way...

CD audio OUT to Line In; MD audio OUT to Playback;

EQ LINE OUT to whatever analog electronic inout you have in mind.

To hear and Equalize the CD set the Input Selector to Source, EQ REC button OFF; to hear the MD equalized set the Input Selector to Tape, EQ REC button OFF.

====

Scenario B:

You have a receiver with only ONE Line Level Aux input and a Tape Loop.

Insert the EQ in the Tape Loop. Attach one of the disc players to AUX and the other to the TAPE conenctions on the EQ.

====

Scenario C

You have a Home Theater System or Audio Vido Reciever.

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.

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 Monitor 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? They would NOT be processed. That logical problem also plays into the decision to defeat digital sources if the Tape Monitor 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 Out (Rec) - to the External Processor (EQ, whatever) Preamp-, Rec, Line-In;

Receiver Tape In (Play) - from the External Processor (EQ, whatever) Preamp-, Play , Line-Out.

So, to sum up, you can only use the EQ or any outboard processor for analog stereo sources. If you actually want to use an analog recording deck you could place it within the typical Equalizer

So what's connected to MD/Video In? That's an external device input. You might want to start there.

configure ur PC (both OS audio and third party sound driver) for surround sounds. control panel- sounds and audio devices - speaker settings - advanced - speker settings. so this done. make sure u select the 6 input channel - the button is on the right edge near the volume knob. near the vol button there are two buttons for selecting input type with up down arrow. from that u can select the input type this will be indicated on the top front indicator. but with the 6 input channel selected all selections are preceeded. if u select stereo mode u will have left/ right audio only.
make sure u connect the input right. connect from computer to 6 channel input. main, surround, center and sub-woofer.  connect the spekers to main (L/R), rear(surround) (L/R), center and sub woofer to terminal marked sub woofer ouput. this done select like i said before the 6 channel button. that should do it.

There's possibly some leakage internally.

Do you have a normal (Playback only) CD player on the MD/CD-R input? It's supposed to support a RECORDING device as you can see by the OUT (REC) connections. A recorder would have shielded cables there and maybe the circuitry is such that ungrounded/unshielded output to the recorder allows a leak of the FM, which is developed inside the receiver.

Since you know that FM is leaking why don't you just selct some other idle source before selecting MD/CD-R? Have you also heard, say, the DVD, if it is playing when you select MD/CD-R?

Or skip the analog route entirelzy and run digital cables from your CD player to one of the Digital Inputs, if you have a spare one. They're all functionally the same. I guarantee the FM won't get in that way.

There's good news and bad news. The bad news is that a multichannel receiver with Bose 901's attached as you have them will only sound right in STEREO on stereo analog material. For one thing, the other speakers around the room are not designed to receive its Active Equalization and for another, if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources. Tape Monitor is for analog stereo material only and on my receiver it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devises for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.

The good news. I have a setup similar to what I think you're trying to do and it works great! With one caveat - My receiver actually has 5.1 analog Outputs so I can drive up to 6 external amplifiers if I want to (I drive 4). Yours does NOT so we have to be creative in extracting the front two channels from your multi-channel receiver. The obvious place would be at one of the few OUTputs on the back, assuming you have one free to use.

I see Video 1 and MD/Tape have Audio Outputs. Use one of these to feed the Bose EQ. **

A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Sony STR-DE595 (Video 1 or MD/Tape Audio Out ***) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.

Attach the 901's to the new amp, set its volume to Max and run through your receivers speaker level setup.

*** In either case you will NOT be able to SELECT the source you use for the 901 Pre-Outs for listening, or else the 901's will not get any sound sent their way. This is what's happening to you right now when you select MD/Tape. You're disconnecting the source from the 901 EQ.

You may have to get ugly with your other input components to find them all homes on the receiver. The labeling won't necessarily match up with the device types. Mine is ugly like that and I have a lot of connectors, but I have even more input devices.

If you have CD, TV Cable box and DVD (typical) you need to assess what you have that is digital and use what you can wherever you can, then the leftover analog device(s) - PC? - can go into any available analog input that is left over.

Whichever of these connections you DO NOT use for the 901's will still be available for using some kind of conventional analog recording device or sound processor such as an EQ or dbx Expander. However, as with any digital receiver, selection of that device for monitoring will kill the sound from any DIGITAL source you have playing (or maybe it just won't allow you to monitor).

It sounds very much like your receiver needs repair by Sony.

press source button repeatedly to select "CD" or "MD" be aware that in order to connecting Ipod to a car stereo you will need to use an extension cable with 3.5 mm stereo connectors on each end to connect iPod to your car stereo system's aux input, or use a cassette adapter if your car stereo doesn't have a sound input jack. Either of these items can be purchased at stores that sell car stereo accessories. good luck!
