[QUOTE="Timo Ulkuniemi, post: 66498, member: 1978"] Hissing channels - nothing connected.. Hello Many microphone preams hiss more, when there is no termination - so open input may be louder than input with microphone connected. i am not at my desk untill monday. But an easy way to test this is : - set up two channels so that they provie equal amount hiss, when turned up one at a time. - turn faders down and plug a XLR-connector with a 200-600 ohm resistor connected between pins 2 & 3 - but only in one channel. - turn faders back up one at a time and observe, if there is any difference. - let us know, what you get.
