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

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 @ 4Ω or 120W @ 8Ω, and channels 1 and 2

may be bridged together to deliver a robust 420W @ 8Ω to a single load.

The AMP-2210S and AMP-3210S are functionally identical. For simplicity within

this guide, the term “AMP2210S/3210S” is used except where noted.

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.

Setup

Installation

Ventilation

Rack Mounting

The AMP-2210S/3210S should be used in a well-ventilated area. The venting holes

should not be obstructed under any circumstances.

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-2210S/3210S can be mounted in a rack or stacked with other equipment.

Two “ears” are provided with the AMP-2210S/3210S so that the unit can be rack

mounted. These ears must be installed prior to mounting. Complete the following

procedure to attach the ears to the unit. The only tool required is a #1 or #2 Phillips

screwdriver.

WARNING: To prevent bodily injury when mounting or servicing this unit in a

rack, take special precautions to ensure that the system remains stable. The following

guidelines are provided to ensure your safety:

 When mounting this unit in a partially filled rack, load the rack from the

bottom to the top with the heaviest component at the bottom of the rack.

 If the rack is provided with stabilizing devices, install the stabilizers before

mounting or servicing the unit in the rack.

NOTE: If rack mounting is not required, rubber feet are provided for tabletop

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-2210S/3210S 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.

Ear Attachment for Rack Mounting

4. Repeat procedure (steps 1 through 3) to attach the remaining ear to the

opposite side.

Stacking

Four “feet” are provided with the AMP-2210S/3210S so that if the unit is not rack

mounted, the rubber feet can provide stability when the unit is placed on a flat

surface or stacked. These feet should be attached prior to the hookup procedure.

Refer to the following illustration for placement of the feet.

Foot Placement for the AMP-2210S/3210S

NOTE: No more than three AMP-2210S/3210S units should be stacked.

If the AMP-2210S/3210S does not power up when it is plugged into an AC outlet,

the fuse may need to be replaced. The fuse holder is located on the rear panel. To

replace the fuse:

CAUTION: Use only time lag type fuses, T6.3AH / 250 Volts. Failure to do so
may cause damage to the AMP-2210T/3210T/2210HT.

1. Disconnect power to the AMP-2210S/3210S.

2. Use a flat head screwdriver to push in the fuse holder.

3. While pushing in the fuse holder, turn screwdriver counterclockwise until

the fuse holder pops out.

Operations & Installation Guide – DOC. 7251A Commercial Power Amplifiers: AMP-2210S/3210S  11

Commercial Power Amplifiers Crestron AMP-2210S/3210S

4. Remove the fuse from the fuse holder and insert a new fuse.

5. Insert the fuse holder in the AMP-2210T/3210T/2210HT.

6. Push in the fuse holder with a flat head screwdriver. While pushing in the

fuse holder, turn the screwdriver clockwise until the fuse holder sets into
place.

7. Push in the fuse holder a little further and turn the screwdriver clockwise

until the fuse holder locks in place.

8. Connect power to the AMP-2210T/3210T/2210HT.

Bridging Inputs/Outputs

Channels 1 and 2 can be bridged to provide a more robust

To bridge channels 1 and 2, refer to the following illustrations.

NOTE: When operating in bridged mode, the CLIPPING and FAULT LEDs for

each channel continue to operate independently.

Operation

Ensure that the procedures and instructions given in “Setup” on page 9 have been

completed, and then do the following:

 Set all INPUT CH LEVEL knobs to their center detent position. These can

be adjusted as necessary to balance the sound between channels or to
accommodate different audio sources.

 Verify that the REMOTE selection switch is set appropriately:

 ON = all channels are turned on

 REMOTE = channels are activated remotely

 Check the front panel LEDs to ensure that power is applied and that a signal

is present on each appropriate channel.

 If an OUTPUT CLIP LED is on (amber), use the corresponding INPUT

CH LEVEL knob to reduce the signal level to eliminate the clipping

condition.

 If an OUTPUT FAULT LED is on (red), eliminate the cause of the fault

condition before continuing.
