TOPIC: 2x4 post analog attenuator

2x4 post analog attenuator 1 year 4 months ago #40499

I'd like to add a 2x4 Balanced to my system but I'm concerned about possible problems running low signals into the unit. It would need to be placed after a source-switcher that also has my main volume attenuator (analog, as the switcher has a number of analog-only sources connected to it), which means I'd be hitting the 2x4's ADC at relatively low levels, and I imagine the result will be a high noise floor and plenty of truncation distortion.

Curious to hear of any possible ways to minimize those issues short of just always running the attenuator at 100% and placing a second one post DSP.

unfortunatelyh there isn't any magic here... No matter if it's a miniDSP 2x4 balanced or any other analog audio device for that mater of fact... :-) Gain structure will always matter. :-)

Make sure that you set your sources to hit the right level. Hopefully you'll have control over them ? Set the 2x4 balanced to the high sensitivity input jumper (0.9V). Else I guess that you would need some autogain sort of device here to automatically adjust the analog gain...
