6ch. volume control + attenuator for DCX2496 on the cheap

Spasticteapot · 19th October 2009, 09:16 PM

I've got a DCX2496, and I'd like to attach a six-channel volume control / attenuator box so that I can get the maximum dynamic range out of it. Instead of using the standard PGA2311 digitally-controlled volume pots, I was thinking of using three stereo 16-step make-before-break attenuators mechanically ganged together in combination with six op-amp amplifiers with the gain set to compensate for the varying sensitivity of each driver.

Is this an advisable solution?

IC way:
- no zipper noise
- fine steps
- remote control
- no extra cables
- builtin opamp is optional

rotary way:
- zip? ZAP!
- crude steps
- no RC

- waay to many cccaaaaaaableees.

indeed , pga2310 is so standard even the deqx have those ?
