balanced. Then, follow the instructions and illustrations below to connect either
unbalanced audio or balanced audio.
CAUTION Wiring the audio incorrectly can damage the audio output circuits.
Pay special attention to the right channel wiring. The + and – layout
differs from most other Extron products.
