17. POWERLINES.
(APPLIESTOTUNERANDRECEIVERSONLY)
Anoutdoor antenna should be located away Irom pow~rIiMIi.
18. OUTDOORANTENNAGROUNDING
(APPLIESTOTUNERANDRECEIVERSONLY)
If an outside antenna is connected to the receiver, be sure the
antenna system is grounded sO as to provide some protection
against voltage surges and builtup static charges.
Section 810 ofthe NationalElectricalCode, ANSI/NFPANo.70-1984,
provides information with respect to proper grounding of the mast
and supporting structure, grounding ofthe lead-inwireto an antenna
discharge unit, size of grounding conductors, location of
antenna-discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode. See Figure.
a) Use No. 10 AWG (5.3 mm~ copper, No. 8 AWG (8.4mm1
aluminum, No. 17 AWG(1.Omm~ copper-clad steel or bronze
wire,or larger, as a ground wire.
b) Secure antenna lead-in and ground wiresto house withstand-off
insulators spaced from 4-6 feet (1.22-1.83 m) apart.
c) Mountantenna discharge unitas close as possible to where lead-in
enters house.
d) Usejumper wirenot smaller than No.6 AWG(13.3mm2)copper,
or the equivalent, when a separate antenna-grounding electrode
isused. SeeNECSection810-210). .

REAR PANEL CONNECTIONS
1.ACLINECORD
PlugtheAC linecordinto a nearby wall outlet that
provides the correct AC power line voltage, or into
an unswitched convenience outlet on any AMC
product.
2.INPUTLEVELCONTROLS
5ach channel of the 2100 has its own independent
level control. Before turning on the 2100 for the
first time. make sure that all level controls are set to
their fully clockwise position. These controls can be
used for various 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.
3. LINE OUTPUTS
Each input has an accompanying line output which
will pass the signal onto another amplifier input or
other line-level device.
4. LINE INPUTS
There are three (one for the BRIDGING mode)
RCA phono connectors on the back panel that
connect to the inputs of each of the power
amplifiers. Connections to these inputs are made
with reference to the MODE SWITCH settings
described above;-
6RIDGING MODE: Connection the input into the
RCAjack of LINE INPUT below "BRIDGING" at the
rear panel.
2CH MODE: In this mode, the 2100 operates as a
2 channel amplifier. Connections to the inputs of
these amplifiers are made the RCA jacks of Land
R
5. LOUDSPEAKER TERMINALS
The 2100 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 wire of 16 gauge or thicker is
recommended specially if low impedance
loudspeakers are used.
The following describes the connections for
BRIDGING and 2 channel operation;-
BRIDGING MODE: When the MODE SWITCH is
set to BRIDGING operation, only the red
terminals on the 2100 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
2100 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 terminal on each loudspeaker is connected
to the corresponding red terminal on the amplifier
and likewise for the black terminals.
6. BRIDGING/2CH "MODE" SWITCH
This switch allows the 2100 to operate in several
modes depending on the number of
loudspeakers to be connected. This mode of
operation is defined as follows;-
BRIDGING MODE: With this switch in the
BRIDGING position, the 2100 becomes a one
channel amplifier capable of driving one 8 ohm
loudspeaker at 200 watts. In this mode. the 2100
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 2100 becomes a two channel (stereo)
amplifier capable of driving, two 8 ohm
loudspeakers at greater than 100 watts per
channel.

1. POWER SWITCH
The press button switch marked power- can be
used to switch the 2100 on or off. When the 2100
is switched on, the small indicator above the
power switch will glow green.
