1. Audio Output (XLR): Use a standard XLR cable to connect this balanced output to your
mixer, PA system, etc.
2. Audio Output (1/4" / 6.35 mm): Use a standard 1/4" (6.35 mm) cable to connect this
unbalanced output to your guitar amplifier, mixer, PA system, etc.

low-impedance active instrument input. Set this switch to Mic if you are connecting it to
an instrument amplifier's high-impedance instrument-level input.
