First, I'd like to explain what I understand so as to better elucidate where I might be confused and help you to help me remedy my misconceptions. Let's assume for now that I want to hang on to my AVR (Denon 3312ci) and yet I would like the option of being able to manually EQ beyond what the AVR's firmware already lets me do.
Where my questions lie is in the placement of signal processing units within the physical topology.
What is the correct placement of a signal processing unit? Between the AVR preout and the amplifier?
If I am not using a dedicated preamp and I am not using the EQ functions of the AVR, would I need a separate DSP for each amplified channel/pair?
Having asked that, of course, if I needed a separate EQ for each pair of speakers, I would just get a pre/pro instead.
Now, if I was using a dedicated pre/pro would there still be any value in having a standalone EQ for each speaker pair, beyond what the pre/pro is capable of? Do people do this?
Now for the issue about which I am most confused: When a product says it is a "31-band parametric stereo EQ" does that mean it equalizes only a LR pair (or SL SR, SBL SBR) of speakers?
If so, are there DEQs that can process signals for all 5 or 7 channels in a 5.1 / 7.1 system? Or am I basically just describing the ultimate function of the pre/pro?
Lastly, just so I can see the big picture, assuming cost was no object, what would the ultimate phyisical topology look like? Please include the total quantities of EQs/FB destroyers/Crossovers necessary to cover all the bases.
As an aside, here is my current system:
PS3 (BD player)
5.0 system, building an enclosure for an LMS-R 15
For the LMS-R 15 I currently have an EP4000 and a CX2310.
Immediately, I am most concerned with knowing what options the CX2310 gives me. Does having such a crossover mean I should ideally use a FL and FR without passive crossovers built into them?
