L-pad? calibration
« on: September 27, 2008, 08:30:17 pm »

Bob katz mentioned here that if converters don't have a calibratible trim on them to use an L-pad. Where could one find these? And, would they be difficult to DIY?

Sure, but depending on how much you need to attenuate you could degrade signal to noise at the output of the mixer.

well what I did was, trimmed to -10dbv mode on converters outputs to the mixer which is at +4dbu, then inputs back on the converter is +4. Since -10 was too much i made up for it with mixers faders, but still within optimal gain structure range as indicated on the mixer itself.
