        MP-AMP40-70V

        Media Presentation Audio Amplifier, 70 Volt

        Discontinued

        This product has been discontinued. Please contact Crestron True Blue Support at 1-888-CRESTRON for a replacement solution or more information.

        Provides an ENERGY STAR® qualified 70V or 100V power amplifier that can be installed virtually anywhere, even above a suspended ceiling.

        The Crestron® MP-AMP40 series offers a choice of 70V or 100V audio amplifiers, each designed to provide a convenient, low-cost amplifier solution for a variety of applications. These amplifiers are ENERGY STAR® qualified to enable organizations to fulfill their green initiatives without compromising on audio performance.[1] Each model is equipped for shelf or surface-mounting to enable installation virtually anywhere without requiring an equipment rack. Each model meets the requirements of UL 2043 for installation in an environmental air-handling (plenum) space, such as above a suspended ceiling[2].

        Two models are offered. The MP-AMP40-70V has a 70 Volt output, and the MP-AMP40-100V has a 100 Volt output. High-efficiency Class D circuitry delivers 40 Watts to drive a distributed speaker system in a meeting room, classroom, or any other space. The output is transformer isolated to handle long and complex wire runs.

        Refined, reliable operation is ensured thanks to pop-free turn-on circuitry and electronic short-circuit and overload protection. An energy-saving design achieves optimum efficiency under load, and the amplifier powers down automatically when no input signal is detected for more than 5 minutes, reducing overall power consumption and heat as part of a green system design. The amplifier quickly powers back on the instant an input signal is detected. Its extruded aluminum housing is both attractive and effective at dissipating heat, affording a silent running design without cooling fans.

        Installation and setup is simple. A detachable output connector facilitates the termination of speaker wiring up to 12 gauge. Balanced and unbalanced inputs accommodate either a mono or stereo line-level source[3], allowing for direct connection to the output of a video projector or display, audio processor, mixer, or AV switcher. Rotary controls provide for adjusting the overall output volume, as well as bass and treble.

        1. The MP-AMP40-70V and MP-AMP40-100V are ENERGY STAR qualified only when using the included power pack. Power pack meets ENERGY STAR Version 2.0 Efficiency Level V standards in compliance with EISA Section 301 (US), CECP Tier 2 (China), MEPS Tier 2 (Australia), and CoC (EU).
        2. The MP-AMP40-70V and MP-AMP40-100V are tested by an NRTL (Nationally Recognized Testing Laboratory) and comply to ANSI/UL2043 (Fire Test For Products Installed in Air-Handling Spaces). Full compliance requires plenum rated cables such as Crestron CBL-KAUDIO-RCAM2-L-P-50 audio cable, CBL-SPK-P-35 speaker cable, and CBL-PWR-EXT24V-P-6 DC power extension cable. Please note that the included power pack is not ANSI/UL2043 compliant, and thus cannot be installed in an air-handling space unless enclosed in a suitable plenum-rated enclosure.
        3. Stereo input is internally summed to mono.
