Crestron AMP-2210S/3210S Commercial Power Amplifiers
Commercial Power Amplifiers,
4/8: AMP-2210S/3210S
Introduction
Crestron®AMP-series Commercial Power Amplifiers provide a perfect combination
of high output and efficiency for all types of professional audio applications. 100%
Crestron engineered and built, these amplifiers are ENERGY STAR®qualified to
enable organizations to fulfill their green initiatives without compromising audio
performance. Advanced design features include a high efficiency amp topology with
active power factor corrected power supply, delivering a generous amount of power
in a space saving 1U rack-mountable chassis.
The AMP-2210S provides two channels of amplification (the AMP-3210S provides
three). Each channel is rated for 210W @ 4Ωor 120W @ 8Ω, and channels 1 and 2
may be bridged together to deliver a robust 420W @ 8Ωto a single load.
The AMP-2210S and AMP-3210S are functionally identical. For simplicity within

Commercial Power Amplifiers Crestron AMP-2210S/3210S
ENERGY STAR®Qualified
Their ultra-efficient design allows the AMP-2210S/3210S to meet demanding
ENERGY STAR qualification requirements, affording a cost reducing solution for
boardrooms, auditoriums, and other commercial systems. Auto power down places
the amplifier into a low power standby state if no input signal is detected for 30
minutes. The amplifier quickly powers back on the instant an input signal is detected.
In addition, each amp channel can be independently enabled or disabled via jumpers
or remote contacts, reducing power consumption by shutting down individual
channels when they are not needed. Whether switched remotely or through an AC
power controller, the AMP-2210S/3210S draw no added inrush current during power
up, reducing AC circuit requirements and potentially eliminating the need for extra
power sequencing equipment.
Professional System Integration
The AMP-2210S/3210S include professional balanced inputs with rear-panel ±10 dB
input level adjustments to assure compatibility with a wide range of audio sources.
Remote power control is enabled for each channel using external contact closures,
switches, or control system relays. All input, output, and remote control connections
are facilitated via detachable screw terminal connectors to simplify installation and
servicing.
Cool and Compact
The AMP-2210S/3210S features a durable, lightweight chassis that may be placed
on a shelf, or rack-mounted using the rack ears provided. At only one rack space
high and under 11 inches (280 mm) deep, it is ideal for installations requiring a lot of
power in a limited space. Their efficient, cool running design gives off substantially
less heat than comparably rated amplifiers. Convection cooling means there are no
noisy fans, allowing the AMP-2210S/3210S to be installed in a boardroom lectern or
credenza without affecting noise levels.
Rugged and Dependable
All AMP-series amplifiers are designed for ultimate dependability in a wide range of
commercial environments. Built-in over current and DC offset protection on each
channel helps prevent damage to the amplifier and speakers due to external or
internal faults. Discrete thermal protection is also provided on each channel and the
power supply. Front panel indicators are provided for each channel to show signal
presence, clipping, and fault conditions.
