Russound A21 00 Installation Manual

PRODUCT OVERVIEW

Introduction

The A21 00 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 Y2-rack design allows for quick installation and gives flexibility of mixing and matching with other

V2-rack products to save valuable equipment rack space.

The powerful 1 00-watt class 0 amplifier in the A21 00 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 A21 00 the perfect choice for even the most space-conscious system designs

1 OOw per channel- A powerful1 00 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 A21 00 can be activated by a 12VDC trigger signal, and can activate additional devices at the same time

Multiple Turn-on modes:

Always On - The A21 00 is always active and ready for use

Signal-sensing -The A21 00 is in a standby mode when no audio signal is present and will turn on when an audio signal is detected

12v Trigg~r - 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:

• 80- optimized mode for 8-ohm stereo output

• 40- optimized mode for 4-ohm stereo output

• Bridge- allows the use of the A21 00 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.

Russound A21 00 Installation Manual

(j) Power Button: Power the front panel switch will manually switch the power on or off.

~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.

@

Line In: Analog stereo audio input for a single input source. When in Bridge Mode, use the .. L .. audio input for the input signal.

@Line Out: A buffered line out is available to extend the audio signal to additional amplifiers as needed.

@Volume: Use this gain switch to attenuate the volume level to meet the room's needs.

@Output: The output switch has three positions, Bridge

(mono), 80 (stereo), 40 (stereo). The default setting is 80.

(])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

@

12VDC Trigger: Turns on the A21 00 when set to Trigger mode and a 12VDC signal is received. The Trigger Out provides 1 OOmA 12VDC max to drive other 12V triggered devices. When using Trigger mode, the front panel power switch must be ON.

®Speaker Out: Connect your loudspeaker(s) here. Up to

12ga AWG wire may be used.

(@ AC Input: Use a 3-prong grounded IEC cord. The locking connector may be engaged to prevent cords from accidentaly dislodging in an equipment rack.

The A21 00 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

A21 00 in a 1 U space or two units in a 1 U 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.

INSTALLATION OPTIONS

Rack Mounting

.

To install one amplifier in a rack space, use the long ear and one of the wallmount 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.

UNIT SETUP AND BRIDGED OPERATION

The A21 00 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 A21 00 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 A21 00 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 A21 00 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.
