Upon loss of audio at all inputs, a timer starts. At the completion of the timing interval, the mixer amplifier enters the standby mode. All circuits not needed to detect audio presence are shut
off. When audio is detected, all circuits turn on and wait for a loss of audio to restart the timing interval. The timer may be disabled if required by system specifications.
The Zone 2 mixer operates from the same 4 inputs as the front-panel Zone 1 mixer. Ducking assignments do not affect the signals in Zone 2. Each input source should be adjusted to the
desired output level. Turn down unused inputs to remove them from the mix. Three Zone 2 outputs are provided. The LINE OUTPUT is balanced and may be used to feed the input of an other
power amplifier. The 600 Ohm output is transformer isolated (providing galvanic isolation) to drive a phone PBX paging input. The 8 Ohm output drives an 8 Ohm speaker with up to 4 W RMS.
MASTER VCA REMOTE CTRL
Connect this RJ45 jack directly to an RDL
remote control. (Examples: RLC10KM or
RLC10KMS) The RJ45 wiring may be
“broken out” for connection to external
OEM 0 to 10 Vdc control, RDL remote
controls (see RLC10K) or 10k Ohm pot.

EFFECTS LOOP CONNECT SWITCH
This switch is normally left in the ON (up)
position when the effects loop is not used.
The switch connects the preamp output from
the Zone 1 mixer directly to the input of the
Zone power amp stage. Set this switch OFF
(down) to insert external processing.
MODULE MOUNTING AREA
This area is reserved for mounting RDL STICK-ON
or TX-Series modules. This example shows a
high-pass filter to protect horn loudspeakers from
bass overload. Other effects possibilities include
equalizers, mixers, crossovers or processors.
MODULE POWER
24 Vdc, 100 mA is available to power external modules.
Balanced LINE signal feeds phone PBX
Connect an 8 Ohm speaker or multiple
speakers configured to present an 8 Ohm
load to the amplifier.
EQUALIZATION
Set the switch to
EQUALIZED (in) if the
front-panel tone controls
should affect the line
output; Set to FLAT (out)
if the tone controls should
not affect the line output.
SIGNAL PRESENT 1 - 4
The green LED glows when audio is present at the input. The indication is not affected by the setting of the mixer level control.
MIXER LEVEL 1 - 4
Adjust each level control for the desired output level. If a master remote control is connected, it will adjust the final
mixer output level. (Note: If the INPUT 1 VCA Bypass is enabled (See INPUT 1 Settings), a connected remote control
will NOT adjust the paging signal on INPUT 1. It will be controlled only by the front panel INPUT 1 level control.)
POWER INDICATOR
Glows dimly when unit is powered in
standby (sleep) mode; glows bright when
amplifier is on; flashes during power-up.
POWER BUTTON
Momentary pushbutton toggles the
amplifier between ON and STANDBY.
TONE CONTROLS
Adjust BASS and TREBLE as desired.
COMPRESSION INDICATOR
LED flashes when audio compressor is
acting on the amplified audio.
ADDITIONAL ZONE AMPLIFIERS
Connect the LINE OUTPUT to the line input of one or
multiple additional RDL amplifiers to permit the Zone
1 mixer to feed other zones. The LINE OUTPUT is not
controlled by the master VCA remote control so each
additional zone may have its own master level control.
The LINE OUTPUT may be set to provide “flat” audio or
to allow equalization by the front-panel tone controls.
The LINE OUTPUT may also be used to feed recording
equipment or an audio distribution amplifier.

ZONE 1 OUTPUT CONNECTIONS
Unplug the power supply and remove the output terminal security cover. Connect constant voltage speakers to a single output voltage tap. Do not connect speakers with dissimilar voltages to multiple
output taps. Total connected load must not exceed 35 W. Upon completion of the output terminal block wiring, re-install the cover over the terminal block prior to plugging in the power supply.
