Connect the sleeve to ground. Connecting the sleeve to a negative (-)
terminal will damage the audio output circuits.
Mono output is selected via RS-232 or the front panel. If mono output is
selected, a mono audio signal is output on both channels (left and right).
If an output connector is wired for balanced output, the level will be 6 dB
higher than if the connector is wired for unbalanced output.
Amplified output (for models with an integrated audio amplifier only) —
The switcher's internal, 40-watt (20 watts per channel into a 4 or 8 ohm
load) audio amplifier outputs stereo (default) or dual mono signals on a
four-position screw terminal connected to nonpowered speakers. Cable
speakers to this screw terminal for a 20 watts (rms) per channel amplified
audio output.
1. Use the appropriate wiring for the load as shown in the following
illustrations.

2. Using the front panel, RS-232, or IP control, set the switcher for either
mono or stereo audio output. That setting affects the amplified output
and the Preamp output.
Do not short the terminals to ground or the amplifier will be damaged.
Do not bridge the outputs. Bridging could damage the amplifier.
