abstractnoiseI too found some channels to be noisy on the IDR32/48-based systems I used, and tracked it down mostly to a pad being used on an input channel with gain up past 30dB. Reducing the gain and poking the PAD button to turn it off soon sorted it.
Also I found that swapping the IDR system in for our previous Soundcraft Live8, I’ve had to increase the system gain at the amp processors by 10dB to get the same sound levels out for the relative levels displayed on the board. This resulted in more headroom across the whole mix, and less background noise in the mix as I was needing a lot less gain at the mic pre’s. I always did prefer to run my analogue desks pretty hot in live mix situations, which is a habit that doesn’t translate well to digital systems.
