Input Level Controls; Line Outputs; Line Inputs; Loudspeaker Terminals - AMC 2100MKII Instructions For Installation And Operation Manual

1. INPUT LEVEL CONTROLS

Each channel of the 2100MKII has its
own independent level control. Before
turning on the 2100MKII for the first time,
make sure that all level controls are set to
their fully clockwise position. These
c o n t r o l s c a n b e u s e d f o r v a r i o u s
functions. For example, they can be used
to match the levels of loudspeakers in a
multi-room installation, or to lower the
sensitivity of the power amplifier, so that
the volume control on pre-amplifier is at a
more convenient and usable position.
They can also be used to optimize the
balance in a stereo system.

2. LINE OUTPUTS

Each input has an accompanying line
output which will pass the signal onto
another amplifier input or other line-level
device.

3. LINE INPUTS

There are three (one for the BRIDGING
mode) RCA phono connectors on the
back panel that connect to the inputs of
e a c h o f t h e p o w e r a m p l i f i e r s .
Connections to these inputs are made
with reference to the MODE SWITCH
settings described above;-
BRIDGING MODE
into the RCA jack of LINE INPUT below
"BRIDGING" at the rear panel.
2CH MODE : In this mode, the 2100MKII
operates as a 2 channel amplifier.
Connections to the inputs of these
amplifiers are made the RCA jacks of L
and R.

4. LOUDSPEAKER TERMINALS

The 2100MKII is equipped with binding
post type speaker terminals that are
designed to handle the extremely high
peak currents that this amplifier is
capable of giving. Connections from
these terminals to the loudspeakers
should be of heavy-duty wire. Standard
w i r e o f 1 6 g a u g e o r t h i c k e r i s
: Connection the input
r e c o m m e n d e d
impedance loudspeakers are used.
The following describes the connections
for BRIDGING and 2 channel operation;-
BRIDGING MODE
SWITCH is set to BRIDGING operation,
only the red terminals on the 2100MKII
are used. For this mode of operation,
connect the red terminal of the speaker to
the red terminal of R CH and the black
speaker terminal to the red terminal of L
CH.
2 CH MODE : When the MODE SWITCH
of the 2100MKII is set to 2 channel
operation, simply connect the wires from
the right speaker to the terminals (marked
+ and -) of R CH, the left speaker to L CH
and so on. Make sure that the red
t e r m i n a l o n e a c h l o u d s p e a k e r i s
connected to the corresponding red
terminal on the amplifier and likewise for
the black terminals.
5. BRIDGING/2 CH "MODE" SWITCH
This switch allows the 2100MKII to
operate in several modes depending on
the number
connected. This mode of operation is
defined as follows;-
BRIDGING MODE
BRIDGING position, the 2100MKII
becomes a one channel amplifier capable
of driving one 8 ohm loudspeaker at 200
watts. In this mode, the 2100MKII can be
used as a high power, audiophile quality
power amplifier.
CAUTION
: In the BRIDGING mode, the
speaker terminals should be directly
wired to the loudspeaker and not to any
accessory device like headphones'
adapters etc. That may share a common
ground with other channels.
2CH MODE : With this switch in the 2CH
position, the 2100MKII becomes a two
channel (stereo) amplifier capable of
driving two 8 ohm loudspeakers at
greater than 100 watts per channel or.
