Have a technics SHGE70 and trying to hook it up to a sony STR-K660P. the receiver has a red and white rcs for dvd audio in and red and whitre video audio in. thats all the rca outlets it has. i unhooked to change rooms anb cant get it to work

I see an EQ and a Receiver with NO Tape Loops or external audio sources mentioned.

Are you implying this used to be hooked up and working? Or are you asking how to integrate the EQ NOW after a move?

Normally the receiver would have a defeatable external loop for Tape recording. THAT is where the EQ or any other processor would go.

The following is mostly boilerplate for receivers WITH a tape loop. You need to understand what will and will not work even if you could attach the EQ.

--- 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? The rest 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. --

If you wanted to Equalize a single external analog source you would have to connect the EQ Line output to either of the two analog inputs ("DVD" or "Video" in your case) and connect your external source to the Playback jacks on the EQ.
