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 @ 4 (or 70V with the AMP-2210HT), or 120W @ 8Ω, 70V, or100V
2
.
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.

To prevent overheating, do not operate this product in an area that exceeds the
environmental temperature range listed in the table of specifications. Consider using
forced air ventilation and/or incrementing the spacing between units to reduce
overheating. Consideration must be given if installed in a closed or multi-unit rack
assembly since the operating ambient temperature of the environment may be greater
than the room ambient temperature. Contact with thermal insulating materials should
be avoided on all sides of the unit.
The AMP-2210T/3210T/2210HT can be mounted in a rack or stacked with other

mounting or stacking. Apply the feet near the corner edges on the underside of the
unit.
NOTE: Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).
To install the ears:
1. There are screws that secure each side of the AMP-2210T/3210T/2210HT
top cover. Using a #1 or #2 Phillips screwdriver, remove the three screws
closest to the front panel from one side of the unit. Refer to the diagram
following step 3 for a detailed view.
2. Position a rack ear so that its mounting holes align with the holes vacated
by the screws in step 1.
3. Secure the ear to the unit with three screws from step 1, as shown in the
following diagram.
