DESCRIPTION

FEATURES (Cont.)

The Extron HPA 502 and HPA 1001-70V are compact power
amplifiers designed for installation in racks and lecterns. These
ENERGY STAR qualified amplifiers feature a highly efficient Class D
amplifier design with patented CDRS - Class D Ripple Suppression
technology from Extron that nearly eliminates EMI emissions and
interference with wireless A/V equipment. This high efficiency allows
the amplifiers to be convection cooled without the need for fans
and operate in environments with little or no ventilation. These
professional grade amplifiers deliver more than 100 dB signal­to-noise ratio, unweighted and THD + Noise of less than 0.05%.
With a compact, plenum-rated 1U, half rack width enclosure, the
HPA 502 and HPA 1001-70V deliver ample power output for speaker
systems in classrooms, meeting rooms, boardrooms, and commercial
environments.

The HPA 502 and HPA 1001-70V are ENERGY STAR
qualified amplifiers and energy efficient products
to help meet green building requirements. They
consume just 8 watts when idle and less than
one watt in standby mode. The HPA 502 and

HPA 1001-70V enter into standby after one hour of
inactivity, or when the standby port is triggered. Additionally, both
amplifiers are plenum-rated, allowing for a concealed installation
above a drop ceiling to prevent theft while providing convenient
placement of A/V equipment.

HPA 502

The HPA 502 two channel amplifier delivers 50 watts rms per channel
into 4 or 8 ohms for amplification of voice or program audio content
to stereo program speakers, or two sets of distributed ceiling speakers
in a dual zone application.

HPA 1001-70V

The HPA 1001-70V delivers 100 watts rms for 70 volt constant voltage
speaker distribution systems for voice reinforcement and PA - public
address applications.

The HPA 502 and HPA 1001-70V accept balanced and unbalanced
input signals and include detented level controls located on the rear
panel to prevent tampering. These controls allow for proper audio
system gain structure, or setting individual levels for each zone.
Remote control capability is available for volume adjustment and
muting. Additionally, both amplifiers include multiple protection
circuits that activate when an abnormal condition, such as excessive
clipping or overheating, is detected.

HPA 1001-70V are energy efficient products to help meet green
building requirements for low power consumption and reduced
operating costs.

HPA 1001-70V generate substantially less heat than conventional
amplifier designs, making them ideal for installation in equipment
racks and lecterns with very limited ventilation. They consume
8 watts when idle and less than 1 watt in standby mode.

exclusive technology from Extron that nearly eliminates the high
frequency switching ripple and EMI emissions found in typical

Class D amplifiers. CDRS enables Extron power amplifiers to be
situated near wireless A/V devices without RF interference.

convection cooled without the need for fans, ensuring quiet, reliable
operation.

Kit, part # 70-228-02 – The HPA 502 and HPA 1001-70V meet UL
2043 for smoke and heat release for installation within a plenum
airspace above a drop ceiling. Above-the-ceiling placement conceals
the amplifier to prevent theft, and is convenient for installing
equipment when space inside the room is limited.

to deliver full-sized amplifier power in half the size of many
conventional amplifiers, the HPA 502 and HPA 1001-70V reduce rack
space requirements for many installations.

HPA 1001-70V automatically enter into a standby mode after one
hour of inactivity, dramatically reducing power consumption. They
quickly return to full power status upon signal detection.
