Input level:
This is
NOT
a volume control. The input sensitivity should be
adjusted to give you maximum output power while minimizing distortion. To set
the input sensitivity, first turn the amp input level control fully counterclockwise.
Turn the source output level up until the signal just starts to distort, and then turn
the source back down slightly so that the distortion goes away. Now rotate the
input level control on the amp clockwise until the signal just starts to distort, then
turn the amp input level control back down slightly so that the distortion goes
away. This setup procedure allows the source and amp to reach maximum clean
output at the same time. For maximum performance/power, the input voltage to
the amplifier should not exceed 6.5 V rms.
3.
Speaker connections:
These connections are high quality 5-way binding
posts. You may connect them with banana plugs, spade connectors, pins or bare
wire. For stereo connection of the amplifier, connect the positive speaker leads to
the red posts and the negative speaker leads to the black posts. For
mono
connection of the amplifier, connect the speaker positive (
+
) to the left, red
binding post and the speaker negative (
-
) to the right, black binding post. The
amplifier is capable of being connected in mono and stereo at the same time, but
a passive crossover should be used.
The
minimum recommended
speaker load on the
LP100Z
©
IS
2-ohm stereo
or
4-ohm mono
. Unlike most car audio amplifiers, the
LP100Z
©
is designed for
maximum power output into BOTH
4-ohm
and
2-ohm stereo
loads, as well as
4-
ohm mono
. The
LP100Z
©
is
NOT 2-ohm mono
stable. If you run a
two-ohm
stereo
or
4 ohm mono
load you
MUST
change the internal power supply taps
(located near the toroid coil) to the settings marked 2. If you change the taps to
the settings marked 2 you must reset the gain adjustment. Failure to reset the
taps or reset the gain adjustment will cause failure of your amplifier and void your
warranty.

12V connection:
Connect
8 AWG or larger
power cable through an inline
fuse to the positive (+) terminal on the battery. Position the inline fuse within 18"
of the battery. The inline fuse should be the same style and rating as the fuse on
the amplifier. Be sure all connections are secure.
5.
Ground Connection:
Connect
8 AWG or larger
power cable directly to a
clean bare metal surface on the car chassis. Use as short a cable run as
possible. Be sure all connections are secure.
6.
Remote connection:
Connect
18 AWG
or larger wire to the remote turn-on
signal or power antenna signal from the source unit. If you do not have either of
these signals available, use the "ignition on" or "accessory" signal to drive a relay
that will connect the battery to the
REM
input on the amplifier when the key is in
the ignition. Be sure all connections are secure.
