Question about DBX 1231 Home Equalizer
I need help how a dbx1231 works, or a home page where I can get some assistant of information

Thanks for the reply. I have sorted it out. The left hand connections are input, and the right hand connections are output. All the rest of the labels appear to be obfuscation. DBX appear to have had some great engineers who lack literacy,or someone with a sick sense of humour.cheers, kingdog

Do you mean you are just going to play back dbx-encode tapes that have already been recorded? Or both playback and record new material? Please explain.

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-, Amp-, Rec-In;
Receiver Tape In (Play) - from the External Processor (EQ, whatever) Preamp-, Amp-, Play-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's own Tape Monitor loop(s). Many have two to facilitate equalized dubbing between decks.
[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.]
