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.

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.

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.

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.

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.

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.
