Bridge 8Ω terminals, the 8Ω/4Ω-70V/100V switch (6) MUST be in the OUT
position and the Stereo-Bridged switch (11) MUST be in the IN (Bridged) position.
4/8Ω: Use the indicated terminals (2 and 3, 4 and 5) to connect a pair of 4-ohm
or 8-ohm speakers (30W@8Ω or 50W@4Ω). WARNING! When using the 4/8Ω
terminals, the 8Ω/4Ω-70V/100V switch (6) MUST be in the OUT position and the
Stereo-Bridged switch (11) MUST also be in the OUT (Stereo) position.
70/100V: Use the indicated terminals (1 and 3, 4 and 6) to connect a pair of
constant voltage speakers (30W@70V/100V). WARNING! When using the
70/100V terminals, the 8Ω/4Ω-70V/100V switch (6) MUST be in the IN position,
the Stereo-Bridged switch (11) MUST also be in the OUT (Stereo) position, and
the 70V/100V HIGH VOLTAGE SPEAKER OUTPUT switch (1) must be set to the
proper voltage.

8Ω/4Ω-70V/100V: Push button switch to select passive (8Ω/4Ω) or constant
voltage (70V/100V) operation. 8Ω/4Ω operation is selected when the switch is in
the OUT position and 70V/100V operation is selected when the switch is in the IN
position.
7.
IR IN/MUTE/STATUS: Connect the included IR transmitter to the IR IN and GND
terminals to allow for zone IR control using the included IR remote control. Connect
a +3 ~ +30 VDC@1mA control voltage to the MUTE and GND terminals to mute the
local zone. Connect a trigger enabled device to the STATUS and GND terminals to
provide a +12 VDC@1mA Status OUT signal to trigger the zone specific device.
8.
LINE/BUS TRIGGER IN: 3.5mm jack for connecting a +3 ~ +30 VDC@1mA control
voltage to determine the zone's audio source. When there is no voltage present, the
zone uses its LINE IN RCA jacks (10) for the audio source. When a +3 ~ +30
VDC@1mA signal is present, the zone uses BUS AUDIO (2 or 3) for the audio source.
9.
LIMITER: Push button switch to determine whether the built-in -20dB Audio Limiter
is used on not. The Audio Limiter is ON when the switch in the IN position and is
OFF when the switch is in the OUT position.
10.
LINE IN: Two RCA jacks for connecting a line level stereo audio source.
11.
STEREO/BRIDGED: Push button switch to determine whether the zone is set for
Bridged or Stereo operation. The zone is set for Stereo operation when the switch is
