Upon loss of input audio, a timer starts. At the completion of the timing interval, the 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.
Connections are made on the rear panel. All connections are on detachable terminal blocks or connectors. The sleep mode delay timer settings are also provided on the rear panel. The tone controls,
indicators and power button are on the front panel.
The input is unbalanced bridging. If this amplifier is fed from the line output of an RDL HD-Series mixer amplifier, it presents a high impedance load to the mixer amplifier output. Up to five HD-Series
amplifiers may be connected to the line output of an HD-Series mixer amplifier. “Y” cords may be used to connect one mixer amplifier to several amplifier inputs, provided the amplifiers are located
together and operate from the same power mains. RDL modules are available to distribute and/or isolate signals in larger systems.
INPUT
Connect a mono or stereo standard unbalanced -10 dBV audio
source to the INPUT. The two input jacks provide active summing
of the left and right channels, thereby preserving the stereo
separation of the audio source.
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.

HD-PA35U
Congratulations on your selection of an RDL HD-Series Ultra-High-Efficiency commercial audio amplifier. The HD-PA35U belongs to the world’s first full-featured environmentally conscious
“green” mixer amplifier series for commercial installations. This amplifier includes equalization, remote control capability and integral analog compression coupled to a sonically pleasing analog-
filtered high efficiency Class D output stage. It is ideally suited for use as a standalone amplifier or to provide an additional amplifier zone from other RDL HD series mixer amplifiers. 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
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.
