The Crestron AMP-X50MP is a low-cost audio amplifier solution that is suitable for a variety of applications. It features a compact, surface‑mountable design that installs virtually anywhere without requiring an equipment rack.

LoZ (4/8 Ω) and Hi-Z (70 V or 100 V) Output
High-efficiency Class D circuitry delivers 25 W per channel to drive one pair of 4 or 8 Ohm speakers, making it ideal to support stereo speakers at the front of a room or mono speakers in the ceiling. The amplifier can also be used with Hi-Z (70/100 V) speakers, delivering 50 W.

Convection Cooling
The efficient design provides cool running operation to ensure long term reliability. The AMP-X50MP is high-density stackable with other Crestron X Series and Modular Amplifiers, allowing multiple units to be installed vertically in an equipment rack without needing extra ventilation space.

Easy Installation
Installation and setup of the AMP-X50MP is simple. Detachable connectors facilitate the termination of wiring. Balanced and unbalanced inputs can connect directly to the line output of a video projector or display, audio processor, mixer, or AV switcher. Independent controls for volume, bass, and treble allow a custom sound in any location.

Fully Protected
The AMP-X50MP features protection against overheating, shorted or overloaded speaker lines, excessive input signals, and other faults. In the case of a shorted speaker line, both outputs mute automatically until the fault condition is resolved.

ENERGY STAR® Certified
An energy-efficient design enables the AMP-X50MP to meet demanding ENERGY STAR requirements. In addition to its high efficiency operation, the AMP-X50MP powers down automatically when no input signal is detected for more than 25 minutes, reducing overall power consumption and heat as part of an Energy Star® compliant system design. The amplifier quickly powers back on the instant an input signal is detected. A remote input can connect to a contact closure to place the amplifier in standby mode.

NOTE: The amplifier is tested by an NRTL (Nationally Recognized Testing Laboratory) and complies 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.
