Crestron AMP-X300 X-Series 4-Channel 300W Amplifier

Benefits

• ENERGY STAR-certified power amplifier
• Half-rack width form factor, gangable with other next-generation, half-rack-width form-factor products using the RMK-AMP-X mounting kit (sold separately)
• Configurable for either LoZ (4/8 ohms) or Hi-Z (70 or 100V) operation
• Low noise, low distortion, and high headroom
• Comprehensive fault and speaker protection
• Captive speaker connectors for secure and robust connectivity
• Balanced and unbalanced inputs
• Standby feature instantly turns on amplifier when input sensing circuitry detects an audio signal
• Always On feature allows constant on connection with very-low power consumption
• Remote standby feature allows for instant on/off control over amplifier outputs via a simple contact closure input
• Front-panel power/standby, fault, and signal/clip indicators

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

The AMP-X300 is a 4-channel amplifier (up to 75W per channel) which can also be configured for 3-channel bridged operation (up to 75W per single-ended channel and up to 150W for the bridged channel), or 2-channel bridged operation (up to 150W per channel), or 1-channel bridged operation (up to 300W), with a choice of "LoZ" outputs to drive 4- or 8-ohm speakers, or "Hi-Z" outputs to drive a distributed speaker system (70 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.

Solid and Efficient Peformance

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 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 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.
