Power Amplifiers
HPA 502 
100 Watt Two Channel Half Rack Power Amplifier
Unique Features
• 50 watts rms per channel into 4 or 8 ohms
•Two channel output for stereo or dual zone applications
•Independent level control for each channel
HPA 1001-70V 
70 Volt 100 Watt Mono Half Rack Power Amplifier
Unique Features
• 100 watts rms output for 70 volt speaker systems
•Input summing — Actively sums incoming left and right channel signals for mono amplification.
•High pass filter — This switch selectable filter rolls off frequencies below 80 Hz to prevent saturation of speaker transformers.
Common Features
•Inputs: Balanced or unbalanced stereo on a captive screw connector
•Speaker Outputs: Screw-lock, 5 mm captive screw connector
•Professional grade amplifier design:
-Less than 0.05% Total Harmonic Distortion plus Noise
-Better than 100 dB Signal-to-Noise
•ENERGY STAR® qualified amplifier — 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.
•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.
•Extron Patented CDRS™ - Class D Ripple Suppression — A patented, exclusive technology from Extron that 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 — The HPA 502 and HPA 1001-70V are convection cooled without the need for fans, ensuring quiet, reliable operation.
•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.
•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.
•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.
•Rear panel detented level controls — Provide attenuation of input signals for setting proper audio system gain staging. They are located on the rear panel to prevent users from tampering with level adjustments.
•Multiple protection circuits — Activate during excessive clipping, thermal overload, or DC faults to prevent damage to the amplifier and speakers.
•Remote standby port — Enables the HPA 502 and HPA 1001-70V to be remotely powered down when not in use, reducing operating cost.
•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.
•Screw-lock, 5 mm captive screw speaker connectors — Enables simple, secure connections with 22 to 14 AWG speaker cables.
•Front and rear-mounted signal and protection indication LEDs — Provide convenient indication of amplifier operation from both sides of an equipment rack.
•Internal international power supply — The 100-240VAC, 50/60 Hz, universal power supply provides worldwide power compatibility.
