. POWER switch – ON/OFF AC power.
3 Power LED – Solid blue LED indicates the unit is ON. Blinking blue LED indicates the unit is in standby mode.
$ INPUT SIGNAL LED – LED is green from –39 dBV to 9 dBV, LED goes red over 9 dBV.
/ OUTPUT LIMIT LED – LED is green from –46 dBFS to –2 dBFS, LED goes red over –2 dBFS, approximately
80 W/channel.
1 AUX INPUT Connector – 1/8” (3.5 mm) stereo line-level input connector. Connection mutes INPUT A and INPUT B for
priority override.
4 INPUT A/B Switch – Allows selection of rear line-input channels A or B.
2 TREBLE/BASS Controls – Provides ±6 dB adjustment at 7 kHz and 100 Hz. One set of controls allows tonal
adjustments of both outputs simultaneously.
( MASTER LEVEL Control* – Controls the overall system volume for both the loudspeakers and the AUX OUTPUT when
the AUX OUTPUT is set to VARIABLE. If the AUX OUTPUT is set to FIXED, then the AUX OUTPUT goes to maximum
level and changes in the MASTER LEVEL do not affect the AUX OUTPUT level.
*When using a REMOTE volume connection the front panel MASTER LEVEL control becomes disabled. When using a REMOTE
volume connection with A/B source selection, either the REMOTE or the front panel can be the MASTER SOURCE control for A/B
select, selectable via a DIP switch. The MASTER LEVEL control will always be from the REMOTE and the front panel MASTER LEVEL
control becomes disabled.

. INPUT A/B – Balanced and unbalance input connectors.
3 INPUT GAIN – Allows for –20 dB to +20 dB of adjustment to each INPUT A/B.
$ PAGE INPUT – Euroblock mic/line input with trigger contact closure for use with push-to-talk microphones.
/ MUTE – Contact closure connection that upon trigger (short) will mute all outputs (including AUX OUTPUT).
1 PAGE INPUT GAIN – Allows for 0 dB to +50 dB of gain control of PAGE INPUT signal.
4 EQ – Provides loudspeaker equalization presets: Flat, DS 16, DS 40, DS 100 and RMU105.
2 PAGE INPUT THRESHOLD – Adjusts the level at which the PAGE INPUT signal causes other inputs to be lowered.
( DIP Switches – A bank of switches to set the amplifier configuration.
, AUX OUTPUT – Variable or fixed line-level output signal for use with ZA zone amplifiers or for routing the signal to
additional audio equipment.
" REMOTE – Input connector for the Bose
®
Volume Control with A/B Switch (PC 041967).
0 OUTPUT 1/OUTPUT 2 TRIM – Allows for up to 40 dB attenuation of the individual loudspeaker outputs relative to the
master level.
# OUTPUT – Two inverted touch-proof 2-pin Euroblock connectors for loudspeaker connections.
% AC Mains receptacle – AC line voltage input.
