AMP-X300

The Crestron® AMP-X300 is a high performance, space saving, energy efficient, professional grade amplifier solution that is totally configurable, yet simple to use. Whether you need a stereo amp that mounts on a wall or under a table, or a multichannel rack mount amp with multiple output types and power levels, the AMP-X300 is simple to specify and install in any configuration.

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

The AMP-X300 is a 4-channel amplifier (up to 75 W per channel) which can also be configured for 3-channel bridged operation (up to 75 W per single ended channel and up to 150 W for the bridged channel), or 2-channel bridged operation (up to 150 W per channel), or 1 channel bridged operation (up to 300 W), with a choice of “LoZ” outputs to drive 4- or 8‑Ω speakers, or “Hi-Z” outputs to drive a distributed speaker system (70V or 100V). Balanced and unbalanced inputs are provided for connection to two stereo or four mono source(s) via detachable terminal blocks or RCA connectors.

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

Solid & Efficient Performance

The AMP-X300 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-X300 is high-density stackable with other Crestron modular amps, allowing multiple units to be installed vertically in an equipment rack without needing extra ventilation space.

Modular Design

The AMP-X300 is housed in a half-width rack-mountable form factor that can be installed individually or ganged together in a single rack space. An optional rack-mounting kit (RMK-AMP-X, sold separately) is available to gang the amplifier together with another half-width model or two quarter-width models. Whether mounting in a rack, attaching to a flat surface, or placing on a shelf, it is easy to combine two amplifiers into a single assembly.

Fully Protected

The AMP-X300 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, both 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 under operation, the AMP-X300 draws no added inrush current during power‑up, thereby reducing AC circuit requirements and allowing multiple units to be connected to a single switched circuit. To reduce energy usage further, the AMP-X300 can be configured to enter a low‑power standby state if no input signal is detected on either channel for 25 minutes. Signal detection has been optimized for sensitivity to improve response time when triggering the amplifier to the "on" state, allowing it to return to full operation within a half‑second the instant an input signal is detected. A remote input can be connected to a contact closure to place the amplifier outputs in controlled standby mode.
