Amplified output (MLS 304SA, MLS 406SA only) — Cable speakers to this
5-position screw terminal for either stereo or dual mono amplified audio
output. The switcher’s default setting is stereo output. Dual mono (the same
signal output on both channels) can be selected via software.
C
Do not short the terminals to ground or the amplifier will be damaged.
Do not connect anything to the middle position of the 5-position screw
terminal; it is not connected to ground.
C Do not bridge mono outputs. Bridging could damage the amplifier.
The SA models’ amplifier power-up delay is 8 seconds for either 4 ohm or
8 ohm output
