lConfigurable for either Lo-Z (4/8 Ω) or Hi-Z (70V or 100V) operation
lBUS line input and output for sending the same signal to multiple amps
lLow noise, low distortion, high headroom
lComprehensive fault and speaker protection
lCaptive speaker connectors for secure and robust connectivity
lBalanced and unbalanced inputs
lStandby feature instantly turns on amplifier when input sensing circuitry detects an audio
signal
lAlways On feature allows constant on connection with minimal power consumption
lInternal universal 100-240V power supply
Lo-Z (4/8 Ω) and Hi-Z (70V or 100V) Operation
The AMP-X500 is a 2-channel amplifier with a BUSline input and output. Using the BUS line, a
signal can be passed through to multiple amps with a single RCAconnection from the source. A
choice of Lo-Z output settings to drive 4- or 8-Ω speakers, or Hi-Z output settings to drive a
distributed speaker system (70V or 100V) can be used. Balanced/Unbalanced inputs are
provided for connection to stereo or two mono sources through detachable terminal blocks or
RCAconnectors.
NOTE: Each configuration can output up to its respective power rating.
Solid andEfficient Performance
The AMP-X500 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.

7 • AMP-X500, AMP-X750, and AMP-X1000 Product Manual — Doc. 9328A
Stackable Design
The AMP-X500 is housed in a compact 1 RU form factor. The efficient design ensures cool
running operation and long term reliability. The amplifier is high-density stackable with other
Crestron amps, allowing multiple units to be installed vertically in an equipment rack without
needing extra ventilation space. Rack mount parts are included, so no additional mounting
accessories or rack shelves are required.
Fully Protected
The AMP-X500 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-X500 to meet demanding ENERGY STAR
requirements. In addition to its high efficiency under operation, the amplifier draws no added
inrush current during power-up, thereby reducing AC circuit requirements and allowing multiple
amplifiers to be connected to a single switched circuit. To reduce energy usage further, the AMP-
X500 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 controlled standby mode.

Lo-Z (4/8 Ω) and Hi-Z (70V or 100V) Operation
The AMP-X750 is a 3-channel amplifier with a BUSline input and output. Using the BUS line, a
signal can be passed through to multiple amps with a single RCAconnection from the source. A
choice of Lo-Z output settings to drive 4- or 8-Ω speakers, or Hi-Z output settings to drive a
distributed speaker system (70V or 100V) can be used. Balanced/Unbalanced inputs are
provided for connection to two stereo or three mono sources through detachable terminal blocks
or RCAconnectors.
NOTE: Each configuration can output up to its respective power rating.
