FEATURES (Cont.)
DESCRIPTION
n ENERGY STAR qualified amplifiers – The HPA 502 and
HPA 1001-70V are energy efficient products to help meet green
building requirements for low power consumption and reduced
operating costs.
n Highly efficient Class D amplifier design – The HPA 502 and
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.
n Patented CDRS - Class D Ripple Suppression – A patented,
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.
n Convection cooled – The HPA 502 and HPA 1001-70V are
convection cooled without the need for fans, ensuring quiet, reliable
operation.
n Plenum rated when used with optional Flexible Conduit Adapter
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.
n Compact 1U, half rack width metal enclosure – With the capability
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.
n Auto-standby with fast power-up – The HPA 502 and
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.
n Rear panel detented level controls – Provide attenuation of input
signals for setting proper audio system gain staging as well as two-
zone applications. Their location on the rear panel prevents users
from tampering with level adjustments.
n Multiple protection circuits – Activate during excessive clipping,
thermal overload, or DC faults to prevent damage to the amplifier
and speakers.
n Remote standby port – Enables the HPA 502 and HPA 1001-70V
to be remotely powered down when not in use, reducing operating
cost.
n Remote volume and mute control port – In basic installations
without third-party control systems, this port allows the HPA 502
and HPA 1001-70V to be remotely controlled using the optional
Extron VCM 100 Series volume and mute or VC 50 volume
controllers.
n Input summing - HPA 1001-70V – Actively sums incoming left and
right channel signals for mono amplification.
n High pass filter - HPA 1001-70V – This switch selectable filter
rolls off frequencies below 80 Hz to prevent saturation of speaker
transformers.
n Screw-lock, 5 mm captive screw speaker connectors – Enables
simple, secure connections with 22 to 14 AWG speaker cables.
n
Front and rear-mounted signal and protection indication LEDs –
Provide convenient indication of amplifier operation from both sides
of an equipment rack.
n Internal international power supply
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 signal-
to-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.
FEATURES
n 50 watts rms per channel into 4 or 8 ohms - HPA 502 – The
HPA 502 provides greater power output for larger rooms than
smaller amplifiers with lower power ratings.
n
100 watts rms output for 70 volt speaker systems - HPA 1001-70V –
The H
PA 1001-70V provides greater power output for larger rooms
than smaller amplifiers with lower power ratings.
n Professional grade amplifier design – The HPA 502 and
HPA 1001-70V deliver more than 100 dB signal-to-noise ratio,
unweighted and THD + Noise of less than 0.05% for ultra-low noise
performance.

Plenum Rated
In many rooms, the space above the ceiling is often used as a return
air plenum. To ensure safety from potentially harmful heat and smoke
release in the event of a fire, A/V products installed in ceilings with a
plenum airspace must comply with safety codes and be specifically
rated for use in plenum environments. The HPA 502 and
HPA 1001-70V power amplifiers are both UL 2043 rated to conform
to heat and smoke release codes for plenum environments. Installing
an amplifier above a drop ceiling offers flexibility for integrators
wanting to conserve rack space and achieve a clean, streamlined
installation free of visible cable runs. An amplifier situated above the
ceiling is also concealed from view, which prevents the possibility of
theft.
Flexible Conduit Adapter Kit
The HPA 502 and HPA 1001-70V feature a built-in power supply with
a modular power connection. In a rack installation, these amplifiers
would be powered from an AC receptacle. However, when the
amplifier is to be permanently situated above a drop ceiling, the
HPA 502 and HPA 1001-70V can be directly hard-wired for AC power
when the optional Flexible Conduit Adapter Kit, part # 70-228-02, is
used in place of a conventional power cord. With this kit, the wiring
is encased in flexible conduit, which connects directly to the amplifier
and a local junction box. This can simplify installation without the
necessity to provide an AC receptacle above the drop ceiling. As with
the HPA 502 and HPA 1001-70V, the Flexible Conduit Adapter Kit is
plenum-rated and meets UL 2043 for smoke and heat release.
