Hi Howie Thanks for the reply. Nope, all in the middle. The headphone test is whats getting me. The sound into the mixer from the turntables when monitoring with headphones is perfect, but I can only hear out of one channel on the speakers at the same time. If I then jack the headphones into the amp headphone port I can only hear one headphone speaker, and one external speaker. Im deducing something is happening the signal @ the amp to give only mono. The input (AUX) is fine as I ten jacked in a Chromecast audio into the AUX input ont he amp and both headphones and speakers are perfect. The amp doesn't seam to like the signal from the mixer and is only allowing mono as far as I can see - what could cause this??
