The Extron HPA 502 and HPA 1001-70Vare 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
n50 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.
n100 watts rms output for 70 volt speaker systems - HPA 1001-70V – The HPA 1001-70V provides greater power output for larger rooms than smaller amplifiers with lower power ratings.
nProfessional 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.
nENERGY 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.
nHighly 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.
nPatented 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.
nConvection cooled – The HPA 502 and HPA 1001-70V are convection cooled without the need for fans, ensuring quiet, reliable operation.
nPlenum 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.
nCompact 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.
nAuto-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.
nRear 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.
nMultiple protection circuits – Activate during excessive clipping, thermal overload, or DC faults to prevent damage to the amplifier and speakers.
nRemote standby port – Enables the HPA 502 and HPA 1001-70V to be remotely powered down when not in use, reducing operating cost.
nRemote 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.
nInput summing - HPA 1001-70V – Actively sums incoming left and right channel signals for mono amplification.
nHigh pass filter - HPA 1001-70V – This switch selectable filter rolls off frequencies below 80 Hz to prevent saturation of speaker transformers.
nScrew-lock, 5 mm captive screw speaker connectors – Enables simple, secure connections with 22 to 14 AWG speaker cables.
nFront and rear-mounted signal and protection indication LEDs – Provide convenient indication of amplifier operation from both sides of an equipment rack.
nInternal international power supply
