Signature 12 stereo out
Hello all. Quick question about my Signature 12 mixer. I plug a mic into the XLR, set gain, volume, eq, pan hard left, route it via the MST button to the Master Stereo outputs, and run a cable from the Master left XLR output to my Bose L1 PA system, which is mono. I bring up the Master volume, yet I get no sound. The only way I get sound is when I route the signal via the GRP button to the Group busses, and then cable from the Group output to the Bose. Any thoughts or suggestion? Your help is much appreciated.
