Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of or more of the following measures: reorient or relocate the receiving antenna; increase the separation between the equipment and receiver; connect the equipment into an outlet on a circuit different from that to which the receiver is connected, or consult the dealer or an experienced radio/TV technician for help.

The A2100 is a 2-channel digital amplifier designed to be used to boost audio amplification where needed, either as a standalone amplifier, or as an addition to a whole-house distributed audio system in order to provide extra amplifier power in larger rooms or spaces. Its space-saving 12 -rack design allows for quick installation and gives flexibility of mixing and matching with other 12 -rack products to save valuable equipment rack space.

The powerful 100-watt class D amplifier in the A2100 is combined with features such as 12v trigger control, audio sensing, volume gain adjustment, and a buffered line output that enables even more amplification of the same audio signal when needed.

Product Features

Class D amplifier - The cool running, low-profile, high efficiency design makes the A2100 the perfect choice for even the most space-conscious system designs

100w per channel – A powerful 100 watts per channel are available to provide ample power to even the largest of spaces

Loop Output - A buffered loop output is available for the audio signal, allowing additional amplifiers to be easily driven from the same signal

Trigger in/out – The A2100 can be activated by a 12VDC trigger signal, and can activate additional devices at the same time

Multiple Turn-on modes:

Always On - The A2100 is always active and ready for use

Signal-sensing - The A2100 is in a standby mode when no audio signal is present and will turn on when an audio signal is detected

12v Trigger - Using the 12v trigger allows precise turn on/off when the amplifier is needed, keeping the unit in a power saving standby mode when not in use

Multiple Output modes:

• 8Ω - optimized mode for 8-ohm stereo output
• 4Ω - optimized mode for 4-ohm stereo output
• Bridge – allows the use of the A2100 as a powerful, 8-ohm mono amplifier

Removable speaker connectors – allow for quick, secure installation and accommodate cables of up to 12 ga AWG

Cord Lock - Flip-down cord lock keeps the IEC power cord in its place, preventing accidental disconnection when moving gear in a stack or when pivoting a rack for service

Thermal Protection

All Russound amplifiers are designed with special circuitry to safeguard the amplifier under a thermal overload condition. Thermal protection mode can only engage when the unit has been run at high volume for extended periods of time without adequate ventilation and/or when speaker impedances are below the minimum levels for the amplifier. If this fault occurs, turn off the amplifier, and check that the speaker impedance rating is above the minimum rating. Also check for adequate ventilation around the amplifier and make adjustments if necessary. Once the unit has cooled to safe operating temperatures, the amplifier may be powered back on.

Protection Circuitry

All Russound amplifiers are designed with special circuitry to safeguard the amplifier under a short-circuit condition. A faulty speaker can also cause a short circuit condition. The front panel LED illuminates orange when the amplifier is in short circuit protection. If this fault condition occurs, turn off the amplifier and check speakers for short circuit conditions when appropriate.

① Power Button: Power - the front panel switch will manually switch the power on or off.
② Power/Standby LED: On start-up, the first LED lights red to show power on. When the amplifier goes into standby, the LED will light amber. The LED will light green during normal operation.
③ Line In: Analog stereo audio input for a single input source. When in Bridge Mode, use the "L" audio input for the input signal.
④ Line Out: A buffered line out is available to extend the audio signal to additional amplifiers as needed.
⑤ Volume: Use this gain switch to attenuate the volume level to meet the room's needs.
⑥ Output: The output switch has three positions, Bridge (mono), 8Ω (stereo), 4Ω (stereo). The default setting is 8Ω.
⑦ Turn-On: There are three turn on-modes: always-on (On), audio sensing (Auto) and activated by the 12v Trigger (Trigger). The default setting is On
⑧ 12VDC Trigger: Turns on the A2100 when set to Trigger mode and a 12VDC signal is received. The Trigger Out provides 100mA 12VDC max to drive other 12V triggered devices. When using Trigger mode, the front panel power switch must be ON.
⑨ Speaker Out: Connect your loudspeaker(s) here. Up to 12ga AWG wire may be used.
⑩ AC Input: Use a 3-prong grounded IEC cord. The locking connector may be engaged to prevent cords from accidentally dislodging in an equipment rack.

The A2100 amplifier can be set on a tabletop or wall-mounted with screws or hook and loop tape. Rack-mounting ears are included to install either one A2100 in a 1U space or two units in a 1U space.

Wall Mounting

The amplifier comes with two wall mounting brackets and attachment screws. There are two attachment locations on each side of the amplifier for more mounting options. Hook and loop tape can be used as well.

Rack Mounting

The rack mounting ears support either one or two amps in a single rack space.

To install one amplifier in a rack space, use the long ear and one of the wall-mount brackets. The unit can be mounted either to the left or right side of the rack space.

Single unit rack mounting option

For two units in one rack space, use the flat plate to support and connect them, and use one wall-mount bracket on each outer side of the units.

When using the two-unit mounting option, the small side ventilation slots on the amps will be next to one another in the middle of the rack space. To avoid overheating situations, make sure the copious top panel ventilation holes are not blocked.

Dual unit rack mounting option

UNIT SETUP AND BRIDGED OPERATION

The A2100 can be used in a side-by-side configuration using the optional rack mounting kit. This feature makes it easy to add amplification to two controllers or two zones (e.g., on the MCA-88 controller).

Another popular application is to use 2 A2100 amplifiers in Bridged Mode, each using one channel of a stereo signal, for a powerful 225 watts per channel @8 ohms.

The example shown shows three A2100 units being used to add amplification

to a Russound MCA-88 controller. One unit is connected in normal 8 ohm stereo mode for an additional room and two A2100 units are shown connected in Bridge mode to add a very powerful outdoor stereo zone.

For the Bridge Mode, connect the negative lead (-) of the speaker cable to the R+ terminal. Connect the positive lead (+) of the speaker cable to the L+ terminal. Set the output switch to Bridge, connect the Line In feed from a source to the Left Line In connection only and restore power to the amplifier.
