How to install mixer devices
I'm going to assume you mean an audio mixer and maybe an AV receiver.
The connections themselves are fairly simple but it pays to understand what happens in the loop. And since you don't name the EQ I'll make some broad generalizations that you should be able to adapt to your equipment. They're all pretty much the same for hook-up anyway.
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 selected 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 some form of 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.
Okay, back to the hook-up:
It's should be clearly marked on the back of the Mixer where everything goes.
The Line IN and Line Out would go to any available Tape Loop on the receiver. Something that has Out's and In's. Obviously, Out's on one device go to In's on the next.
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 or anothere processor you could place it within the typical Equalizer's own Tape Monitor loop(s). Many have two to facilitate equalized dubbing between decks and those loops can be engaged or bypassed via controls on the EQ or Processor.
