AMP-X75

The Crestron® AMP-X75 is a high performance, space saving, energy efficient amplifier that’s 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 Ω) 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.

NOTE: Each configuration can output up to its respective power rating.

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.

Modular Design

The AMP-X75 is housed in a quarter-width rack-mountable form factor that can be installed individually or ganged together with other units in a single rack space. The amplifier ships complete with all the hardware required for installation. Rack and surface mount parts are included, so there are no other mounting accessories or rack shelves to purchase. Whether mounting in a rack, attaching to a flat surface, or placing on a shelf, it’s easy to combine multiple amplifiers into a single assembly.

Fully Protected

The AMP-X75 features protection against overheating, shorted or overloaded speaker lines, excessive input signals, and other faults. In the case of a shorted speaker line or overheating condition, outputs mute automatically until the fault condition is resolved. In the event of a prolonged fault, such as an internal component failure, the outputs mute instantly and the amplifier shuts down.

Energy Efficient

In addition to its high efficiency operation, the AMP-X75 powers down automatically when no input signal is detected for more than 25 minutes, reducing overall power consumption and heat. 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.
