Introduction

Commercial Power Amplifiers, 4/8Ω or 70/100V: AMP-2210T/3210T/2210HT

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 amplifiers are available in three models:

Models

Two independent channels with each channel rated for 210W @ 4Ω, or 120 Ω@ 8Ω, 70V or 100V| AMP-2210T
Three independent channels with each channel rated for 210Ω @ 4Ω, or 120Ω @ 8Ω, 70V or 100V| AMP-3210T
Two independent channels with each channel rated for 210Ω @ 70V or 4Ω, or 120 Ω @ 8WΩ*| AMP-2210HT

In addition, channels 1 and 2 may be bridged together to deliver a robust 420W @ 8Ω to a single load. The 70/100V outputs are transformer isolated to handle long and complex wire runs.

The AMP-2210T, AMP-3210T, and AMP-2210HT are functionally identical. For simplicity within this guide, the term “AMP-2210T/3210T/2210HT” is used except where noted.

2-or 3-Channel Universal Design

The AMP-2210T and AMP-2210HT provide two independent channels of amplification–the AMP-3210T provides three–with configurable outputs to suit a range of system designs. Each channel is configurable via a simple selector switch to handle either low-Z or constant voltage speaker systems. Each channel is rated for 210W @ 4Ω (or 70V with the AMP-2210HT), or 120W @ 8Ω, 70V, or100V2. Additionally, channels 1 and 2 may be bridged together to deliver a robust 420W @ 8Ω to a single load. On the AMP-2210T and AMP-3210T, the 70/100V outputs are transformer isolated to handle long and complex wire runs.

ENERGY STAR® Qualified

Its ultra-efficient design allows the AMP-2210T/3210T/2210HT 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-2210T/3210T/2210HT draws no added inrush current during power up, reducing AC circuit requirements and potentially eliminating the need for extra power sequencing equipment.

1. The 70V constant voltage output of the AMP-2210HT is not transformer isolated.
2. 100V operation not available on AMP-2210HT.

Professional System Integration

The AMP-2210T/3210T/2210HT includes 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-2210T/3210T/2210HT 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 15 inches (381 mm) deep, they are 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-2210T/3210T/2210HT 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.
