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 100-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 bya
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. Ifthis fault condition occurs, turn
off
the
amplifier and check speakers for short circuit conditions when appropriate.

Wall mounting option
INSTALLATION OPTIONS
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 connectthem,
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
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
astereo signal, for a powerful
225
watts per channel
@8
ohms.
The example shown shows three
A21
00
units being used
to
add amplification
RCA
Cable
to
a Russound MCA-88 controller. One unit
is
connected in normal 8
ohm
stereo modefor
an
additional room and
two
A21
00
units are shown connected
in Bridge mode
to
add avery 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.
