INSTALLATION AND OPERATION
INTRODUCTION
INPUT WIRING
PRIORITY PAGING INPUTS 3 & 4
INPUT 1 INPUT 2
CONNECTIONS
Four inputs may be connected. Each input is available on the primary Zone 1 front-panel mixer and on the Zone 2 rear-panel mixer. If used, the paging source is usually connected to Input 1.
The front-end preamplifier stages for Inputs 1 and 2 are each equipped with a gain trimmer. The dual-LED VU meter displays the signal level for Inputs 1 and 2 following the preamplifiers. This
allows each input gain trimmer to be set properly for the optimum signal-to-noise ratio, avoiding the possibility of input clipping common to mixers with unmetered input stages.
Connections are made on the rear panel. All connections are on detachable terminal blocks or connectors. The Zone 2 mixer, Inputs 1 and 2 gain trimmers and VU-meter, ducking controls and
assignments, phantom voltage selectors and sleep mode delay timer settings are also provided on the rear panel. The Zone 1 mixer, tone controls, indicators and power button are on the front panel.
Balanced MIC or LINE source connected
using a single-pair shielded audio cable
Unbalanced MIC or LINE source connected using
a single-conductor shielded audio cable
Balanced LINE signal from phone
PBX or audio transformer
INPUT 1
Connect a MIC or LINE source. This is normally a paging mic or the line-level paging output from a phone PBX. The line-level
input is transformer balanced (providing galvanic isolation) and may be connected balanced or unbalanced.
INPUT 2
Connect a MIC or LINE source. The line-level input is
active balanced and may be connected balanced or
unbalanced.
INPUTS 3 & 4
Connect a mono or stereo standard unbalanced -10 dBV audio
source to INPUTs 3 and/or 4. The two input jacks associated with
each input provide active summing of the left and right channels,
thereby preserving the stereo separation of the audio source.
MIC or LINE Gain
Set the Input Gain to MIC or LINE/TEL according to the input
signal connected.
MIC or LINE Gain
Set the Input Gain to MIC or LINE
according to the input signal connected.
GAIN TRIM
Feed a normal signal level into INPUT 1 and adjust the GAIN
TRIM for maximum brightness of the NORM green LED with
occasional flashing of the red PEAK LED. (Disconnect INPUT 2
during this adjustment.)
GAIN TRIM
Feed a normal signal level into
INPUT 2 and adjust the GAIN TRIM
for maximum brightness of the NORM
green LED with occasional flashing
of the red PEAK LED. (Disconnect
INPUT 1 during this adjustment.)
VOX (VOICE-ACTIVATED PRIORITY)
If a paging signal is to automatically “duck” (fade down) other
audio inputs, feed a normal paging signal into INPUT 1 and adjust
the SENSITIVITY trimmer until the LED flashes regularly. Set the
SENSITIVITY trimmer fully CCW to disable the VOX function.
MANUAL PRIORITY
If a swich (such as a paging mic push-to-talk switch) should “duck” (fade down) other audio inputs, connect the switch to the DUCK and Ground terminals.
INPUT DUCKING SELECTOR
Select any or all inputs (2, 3 and/or 4) to be ducked when a paging priority is detected (VOX activated by audio signal on INPUT 1, or
MANUAL activation by an external switch. Selected inputs are ducked only in Zone 1 (the primary amplified output). Set the switch
ON (switch up) to duck the input in Zone 1; set the switch OFF to prevent ducking. Inputs are not ducked in Zone 2.
FADE-UP DELAY
Adjust the FADE-UP DELAY trimmer to delay the start of the
audio fade-up following the release of an external manual priority
switch and/or VOX priority detection.
PHANTOM VOLTAGE
If a condenser mic may be connected to INPUT 1, set the
phantom voltage ON (switch up).
INPUT 1 BYPASS EQUALIZATION
If the INPUT 1 (paging) signal equalization is to be adjusted by the front-panel tone controls, set the switch OFF (down). If the
tone controls are
not intended to adjust the frequency response of INPUT 1, set the switch ON (up).
PHANTOM VOLTAGE
If a condenser mic may be connected
to INPUT 2, set the phantom voltage
ON (switch up).

HD-RA35U
Congratulations on your selection of an RDL HD-Series Ultra-High-Efficiency commercial mixer amplifier. The HD-RA35U is part of the world’s first full-featured environmentally conscious
“green” mixer amplifier series for commercial installations. This product includes studio quality microphone input stages, line-level transformer isolation, equalization, remote control capability
and integral analog compression coupled to sonically pleasing analog-filtered high efficiency Class D output stages. An internal low-power-consumption processor monitors usage demands
to completely shut down internal circuitry for maximum power conservation and extremely low long-term operating cost. The HD-Series mixer amplifiers are designed and manufactured in the
U.S.A. using the most advanced automated manufacturing and testing processes for years of reliable high performance and cost savings.

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.
REMOTE MIXING CONTROL
Connect this RJ45 jack directly to an RDL
remote control. (Examples: D/DS-RC3 or
D/DS-RC3M) The RJ45 wiring may be
“broken out” for connection to external

potentiometers.

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
Note: Remote control labels for
INPUTs 1, 2 and 3 correspond to
mixer-amplifier inputs 2, 3 and 4
respectively.
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 The green LED glows when audio is present at INPUT 1. The indication is not affected by the setting of the mixer level control.
MIXER LEVEL 1
Adjust the level control for the desired output level. INPUT 1 is usually the paging signal. The level for this source is
set on the front panel and is unaffected by the remote control. Inputs 2, 3 and 4 are adjusted using the level controls
on the remote control. Note: Multiple compatible RDL remote controls are available separately.
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 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.
