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.

How is this different from a preamp with a sub out? You control the frequency and volume at your sub. I'm obviously missing something...

 

@thecarpathian i haven’t seen too many preamps with full bass management including separately adjustable high- and low-pass filter frequencies and slopes. Much more basic sub outputs and non-adjustable crossovers, yes, but even those there aren’t a whole lot of.

I use 2 Mcintosh C50 preamps. 1 to control my main speakers and 1 for my 3 subwoofers. Bass output of the extremely diverse music I enjoy varies greatly and this ended up being the best way to remedy the problem. After time I pretty much know where each volume goes in relationship to one another. I looked for a preamp with 2 separate volume control for 2 separate outputs for years and had no luck, so I sympathize with Ed's conundrum.

The market is crying for a preamp with proper bass management. Straight through, HP out, Variable LP output, variable frequency and at least a couple HP/LP slopes. both balanced and unbalanced. Inputs and outputs. Throw in source switching, stereo/mono/l/r switching and a balance control, use some quality parts, and you're done. It's not that tough.
