The Crestron® AMP-X75 is a high performance, space saving, energy efficient amplifier that' totally configurable, yet simple to use. Whether you need a stereo amplifier that mounts on a wall or under a table, or a high impedance speaker run fed from a rack mounted unit, the AMP-X75 is simple to specify and install in any configuration.

LoZ (4/8 ohms) and Hi-Z (70V or 100V) Output

The AMP-X75 is a 2-channel amplifier (up to 35 W per single-ended, low impedance channel) which can also be configured for a single channel of bridged operation (up to 75 W for the bridged channel), or for a single channel of high impedance operation (up to 75 W) to drive a distributed speaker system (70V or 100V). Balanced and unbalanced inputs are available for connection to a single stereo or two mono source(s) via detachable terminal blocks or a 3.5 mm TRS connector. Balanced and unbalanced inputs are summed for simultaneous use.

Solid and Efficient Performance

The AMP-X75 is engineered to deliver exceptional performance and reliability with low distortion, low noise, and high power headroom. Advanced Class D technology maximizes efficiency to reduce power consumption and heat dissipation. An internal universal power supply ensures consistent performance at varying line voltages.

Convection Cooling

The efficient design ensures cool running operation and long-term reliability. The AMP-X75 is high-density stackable with other Crestron modular amplifiers, allowing multiple units to be installed vertically in an equipment rack without needing extra ventilation space.
