The AMP-X500 is a high performance, compact, energy efficient, professional grade amplifier. Supporting Lo-Z and Hi-Z operation, this multichannel amplifier is suitable for both residential and commercial configurations.

Lo-Z (4/8 Ω) and Hi-Z (70V or 100V) Operation
The AMP-X500 is a 2-channel amplifier with up to 500 W of total available output power. Each amplifier channel can be configured for Lo-Z output to drive 4 or 8 Ω speakers or Hi-Z output to drive a 70V or 100V distributed speaker system. A stereo BUS line input and output are available, allowing an audio signal to be distributed to multiple amplifiers from one source. Alternatively, dedicated balanced and unbalanced inputs are provided for connection to a stereo source or up to two mono sources.

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

Solid and Efficient Performance
The AMP-X500 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.

Stackable Design
The AMP-X500 is housed in a compact 1 RU form factor. The efficient design ensures cool running operation and long term reliability. The amplifier is high-density stackable with other Crestron amps, allowing multiple units to be installed vertically in an equipment rack without needing extra ventilation space. Rack mount parts are included, so no additional mounting accessories or rack shelves are required.

Fully Protected
The AMP-X500 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, affected outputs mute automatically until the fault condition is resolved.

Energy Efficient
In addition to its high efficiency under operation, the amplifier draws no added inrush current during power‑up, thereby reducing AC circuit requirements and allowing multiple amplifiers to be connected to a single switched circuit. To reduce energy usage further, the AMP-X500 can be configured to enter a low-power standby state if no input signal is detected on any channel for 25 minutes. Signal detection sensitivity has been optimized to improve response time when triggering the amplifier to the on state, allowing it to return to full operation within a half-second. The REMOTE input can be connected to a contact closure to place the amplifier outputs in controlled standby mode.
