Lo-Z and Hi-Z Operation
The AMP-X300 is a 4-channel amplifier (up to 75 W per channel) that can be configured for various operation modes:
- 3-channel bridged operation (up to 75 W per single-ended channel and up to 150 W for the bridged channel)
- 2-channel bridged operation (up to 150 W per channel)
- 1-channel bridged operation (up to 300 W)
A choice of Lo-Z outputs to drive 4- or 8-Ω speakers, or Hi-Z outputs to drive a distributed speaker system (70V or 100V) can be used. Balanced and unbalanced inputs are provided for connection to two stereo or four mono sources through detachable terminal blocks or RCA connectors.
Solid and 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.
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. The amplifier 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. Rack and surface mount parts are included, so no additional mounting accessories or rack shelves are required.
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, paired outputs mute automatically until the fault condition is resolved. In the event of a prolonged fault, all outputs mute and the amplifier shuts down.
Energy Star® Certified
An energy-efficient design enables the AMP-X300 to meet demanding ENERGY STAR requirements. In addition to its high efficiency under operation, the amplifier draws no added inrush current during power-up, reducing AC circuit requirements and allowing multiple amplifiers 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 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 a controlled standby mode.
