        AMP-225

        Dual-Channel Modular Power Amplifier, 25 W/Ch., 4/8 Ω

        Provides a professional amplifier solution for commercial applications that saves energy, space, and money. Unique modular design is super easy to configure and ships with everything required to enable surface mounting, rack mounting, and ganging multiple units together.

        The Crestron AMP-225 is a space saving, energy efficient, commercial grade amplifier solution that’s totally configurable yet remarkably straightforward. Crestron® modular amps are simple to specify and install in any configuration.

        All‑Inclusive Modular Design
        The AMP-225 is a Lo‑Z modular amplifier housed in a quarter-width rack-mountable form factor that can be installed individually or ganged together in a single rack space. The AMP-225 ships with all the hardware required for installation of the unit by itself or in combination with any other unit(s). Rack and surface mount kits are included, so there are no other mounting accessories or rack shelves to purchase.

        4/8 Ω Output
        The AMP-225 is a dual channel amplifier, conservatively rated at 25 W per channel, with Lo‑Z outputs to drive 4 or 8 Ohm speakers. Output wiring is facilitated using detachable terminal blocks. Balanced and unbalanced inputs are provided for connection to one stereo or two mono source(s) via a detachable terminal block or RCA connectors.

        Solid & Efficient Performance
        The AMP-225 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 with power factor correction ensures consistent performance at varying line voltages.

        Convection Cooled
        The ultra‑efficient design of the AMP-225 ensures cool running operation without the use of internal fans. This means there’s no fan noise and no moving parts to break down. Cool operation also helps to ensure long term reliability. The AMP-225 is high‑density stackable with other Crestron modular amps, allowing multiple amplifiers to be installed vertically in an equipment rack without extra ventilation space in between.

        Fully Protected
        The AMP-225 features comprehensive protection against overheating, shorted or overloaded speaker lines, excessive input signals, and other faults. Built‑in clip limiting prevents extreme output signals and distortion that can damage the speakers or amplifier. 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
        Its energy‑efficient design enables the AMP-225 to meet demanding ENERGY STAR requirements. Crestron modular amps, like the AMP-225, allow organizations to fulfill their green initiatives without compromising on audio performance. In addition to its high efficiency under operation, the AMP-225 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.
