Hey, I just purchased two XTI's and have a problem getting different mixes with the monitors.I ran two signals from the amp from AUX 1 and 2 in the board. However I cannot get a separate mix for the two channels. The Amp output ch1 and ch2 want to respond like bass and tweeter and I cannot separate the channels. I have made sure the internal crossover is switched off in the setting I am using. However continues to split the Lo and Hi end. Any suggestions would be great.
