Somebody Please Make This Already...

Imagine an interesting new product: Two sets of analog inputs (when I say sets, I mean each set has single-ended and also balanced), one volume attenuator that controls output synchronously BY WAY OF TWO SETS OF SYNCHRONIZED RESISTOR LADDERS (analog-domain attenuation, not digital) between the two sets of inputs, and then matched sets of outputs (again, both, single-ended and balanced). The entire device should be active, so that if you use single-ended input, it can still output a balanced, differential signal after the volume control, and on the output end there should be an option to combine L/R signals into a single signal (like an LFE output).

Even better yet, we should allow adjustable high-pass filter on the first set of in/outputs and an adjustable low-pass filter on the second set of in/outputs. Slope and frequency should both be adjustable. And of course both filters can be separately bypassed.

The unit should also have a single 12V trigger input and three 12V trigger outputs, and it should have a remote control that can control volume, filter slopes and filter frequencies.

Why do you need two synchronized volume controls?

I assume you have 2 amps, one SE and on XLR. you want them to go up and down at the same rate but how are you going to set them at the same level to begin with? so you have to ask for an adjustable offset between the 2 outputs.

This is already available for AV--any AV receiver allows you to set the levels of each speaker or even automatically does it for you with a microphone.

If you are looking for something for your 2 channel system biamped, I think you’re looking for a custom piece.

I didn't suggest using an AV receiver for 2 channel sound.  I just was addressing if you want to use it for AV.

Now I know you're looking for subwoofer volume control. I don't use subs but I know that many subs have a high level input so the sub and speaker are driven off the same wire.  I know a lot of sub users have solved this and now that they know what you're asking, maybe they will have some suggestions.
