Rear Panel Overview
1 AC POWER INLET AND SWITCH
Connect the included AC power
cord to this standard 15A, IEC
type inlet. Supported mains
voltage range is 100-240V~.
AC power switch disconnects amplifier
completely from AC mains.
2 BRIDGE/MONO
MODE
Set the switch to the UP position per
zone to enable Bridge/Mono Mode.
When Bridge/Mono is enabled for a
zone, the Left and Right inputs are
summed to mono.
In Bridge/Mono mode, outputs can be
used in either Bridge outputs or single
channel pairs.
3 LINK TO GLOBAL INPUT
Set the switch to the UP position to link a
zone to the ZONE 1 INPUT/ GLOBAL
INPUT
4 POWER
MODE
ON: Always On
12V: Controlled by 12VDC trigger.
AUTO: Turn on when an audio signal is
sensed on the audio input
5 12V
TRIGGER
IN/OUT
The Trigger In and Out connections
provide 1/8” (3.5mm) mono mini-plug
connectors.
Use the Trigger In for making
connections to external control devices
that will activate and deactivate the DA
amplifier standby mode. The Trigger Out
can be used for making Trigger In daisy-
chain connections to additional DA
series amplifiers or other components
that need to mimic the amplifier’s power
state.
6 GLOBAL
OUT
Provides a line-level RCA connector
loop/pass thru output for connecting
multiple DA amplifiers in a
system utilizing a single Global input
signal.
7
ZONE 1 INPUT / GLOBAL IN
Provides a line-level RCA connector
input to feed the corresponding speaker-
level output channel.
Additionally, this input can also feed
any/all speaker output channels by
utilizing the LINK TO GLOBAL INPUT
switches.
8 OUTPUT LEVEL CONTROLS AND
CLIP INDICATOR
Provides output level attenuation per
Zone pair.
The output level controls function as
attenuators for each zone and can be
used to level-match zones in an
installation.
The CLIP indicator LED is located below
the GAIN control. If clipping is present
while playing an input source, the CLIP
LED will flash red.
9 LOCAL
INPUTS
/ ZONE INPUTS
Provides a line-level RCA connector
input to feed a corresponding speaker-
level output channel.
When used as a multi-zone amplifier,
each channel can be provided with a
dedicated input signal. The signals from
this input will only be available on the
corresponding speaker-level output.
Local inputs are grouped and identified
both by Zone, and channel numbers 1-8
on the rear panel.
10 OUTPUT TERMINAL (PHOENIX
BLOCK) CONNECTORS
Two four-pole, touch-proof
terminal strip per channel pair.
Accepts up to 12 AWG wire or
terminal forks.
