Equalizer for 7.1?

You really only need EQ it for the subwoofer.

EQ is only effective for minimum phase relationships above the Schroeder frequency(region) where modal behavior ends and specular behavior begins.

EQ is NOT appropriate to address non-minimum phase behavior above the low frequencies.

Use signal alignment and treatment above that point and control the interaction of early and later arriving high gain reflections to minimize the destructive comb filtering/coloration and errant locational cues.

There are products to do this but they are very expensive.

Here is what I was thinking you meant:

But it needs to be inserted between a preamp and an amp. Your best bet might just be a bunch of 2-channel EQs.

You would need to set up either a single channnel EQ for each channel, or three dual channel and a single channel, and then a parametric for the Sub. Only reason that I can see using a EQ over the software of the avrs, is if you are like me, and want more control of how the sound is tweaked vs. just going with the standards that the manufacturer has set up.

Also, you would need a separate amp for each channel, a pre-amp vs avrs with amp, a compressor/limiter with delay, so you are talking a few thousand dollars for a decent setup. If the software that your AVRS has for tweaking the sound is doing its job, stick with it for 7.1. If wanting better sound for 2 channel, for music, and that is all you are listening to, go with a decent eq or parametric.

Keep in mind, that a lot confuse the use of a equalizer, whether non-parametric or parametric, with only being used with a sub-woofer, or in live settings. I use a parametric, so that I have better control over how my music sounds, along with tv programming, since all I use is a 2 channel set up, and can get better control than with a non-parametric 31 band graphic.

As mentioned, if you use is not to correct for speaker-room response issues, they can be used essentially as tone controls to modify the direct signal. In which case you would insert a dedicated EQ in-line with each channel that you want to modify.

But if such is the case, I might suggest alternative options such as reexamining your choice of speakers...

Best of luck...

You can't do what you are trying to do by attaching to the outputs from an amplifier (the speaker outs). If your receiver has preamplifier outputs for all the channels (i.e. L/C/R/SR/SL/Sub etc.) then you can get the equalizer and insert it between the receiver and a separate power amplifier (i.e. a 5ch amplifier).

There will be plenty options for used amplifiers and/or equalizers if you want to keep the cost down.

Correct. Your receiver does not have pre-outs. You can get any 7.1 receiver that has pre-outs--it will most likely be less costly than a separate preamp. Look for one that has pre-out/main-in shorting pins. Some NAD and Denon products did although they are probably others as well. I would still recommend the EQ I suggested. You will just need to wire the pre-out from the receiver into the EQ and back in the main-in on the receiver. This would allow you to get away with two pieces.

The other option is what someone else suggested and that is to find an AVR with a manual EQ function (built-in) for all the speakers. I don't know all the models out these days, but my guess is that will be much more difficult to find as most products have auto EQ to do room correction and other types of correction that you are not interested in and won't serve your needs.

Are you gaming with an HTPC or console? If it is with an HTPC you can use JRiver Media Center. You can route all sound through it from any program on the computer. You can then use its advanced bass management, parametric EQ, limiting, and much more signal processing. You can apply processing to any or all channels. I'm using it for gaming on the HTPC and it works great.

Leaving aside the questionable wisdom of this, another option (once pre-outs are available and assuming you have power amps/pre-ins) is to pick up a miniDSP or similar unit and EQ using your PC.

Those modern receivers that I'm familiar with which include Audyssey audio processing also include manual EQ settings (which disable the Audyssey processing if they're used). However, they're not nearly so satisfying or as easy to use as external graphical equalizers: you can't see their settings without selecting appropriate on-screen menus. On the other hand, manual EQing usually can't do as good a job of correcting for room and speaker deficiencies as the more sophisticated automated processing that's available.

Don't forget that you'll want to get a spectrum analyzer, too, so you can see exactly what changes actually have been made in your audio environment. Human hearing is notoriously unreliable. Dedicated devices as well as computer software packages are readily available.

Some SPL meters have a line-level signal output so they can be used as a microphone for doing measurements. If yours has one, it could be used with any of the free spectrum analyzer programs. Many more hours of fun!

Yamaha receivers have parametric EQ for all channels. This would do what you are after.

The RS SPL meter output should go into the line in, not mic in, of your PC.
