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 (70V or 100V) 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 (70/100V) 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. A knob cover
is included with the product to protect against accidental
changes to the front panel settings.
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.
