INPUT SECTION
The M400/4-24V’s input section allows you
to send signals to the amplifier section through
the use of two or four differential inputs.
Input connections are made via one or two
pairs of traditional RCA-type jacks.

If you wish to send eight discrete channels
into the M800/8-24V, simply use all eight
inputs and set the “Input Mode” switch in the
“8 Ch.” position.
If you wish to feed all eight channels by using
only four channels of input, set the “Input Mode”
switch to “4 Ch.” and use only the inputs to
channels 1, 2, 5 and 6. In this mode, input 1 will
feed channels 1 and 3, input 2 will feed channels
3 and 4, input 5 will feed channels 5 and 7 and
input 6 will feed channels 6 and 8.
If you wish to use only two channels of input
to deliver signal to all eight amplifier channels,
set the “Input Mode” switch to “2 Ch.” and
use only the inputs to channels 1 and 2. In this
mode, input 1 will feed all the odd-numbered
channels (1, 3, 5 and 7) and input 2 will feed all
the even-numbered channels (2, 4, 6 and 8).

Marine 8 Channel Amplifier
NOT FOR USE IN 12V SYSTEMS!
-24V
Input Voltage Range:
The M800/8-24V’s input sections are designed
to accept signal voltages from 100mV – 4V. This
will accommodate all preamp level signals and
many speaker level signals.
To use speaker-level sources, simply splice the
speaker output wires of the source unit onto a
pair of RCA plugs for each input pair. (or use JL
Audio part XD-CLRAIC2-SW) No “line output
converter” is needed in most cases.
If you find that the output cannot be reduced
sufficiently with a direct speaker level signal
applied to the amplifier, you may use a “line
output converter” to reduce the signal level.
INPUT SENSITIVITY CONTROLS
The controls labeled “Input Sens.” located in
each channel section can be used to match the
source unit’s output voltage to the input stage of
each pair of amplifier channels for maximum
clean output. Rotating the control clockwise will
result in higher sensitivity (louder for a given
input voltage). Rotating the control counter-
clockwise will result in lower sensitivity (quieter
for a given input voltage.)

To properly set the amplifier for maximum
clean output, please refer to Appendix A (page
14) in this manual. After using this procedure,
you can then adjust any or all “Input Sens.”
levels downward if this is required to achieve the
desired system balance.
Do not increase any “Input Sens.” setting for
any channel(s) of any amplifier in the system
beyond the maximum level established during
the procedure outlined in Appendix A (page 14).
Doing so will result in audible distortion and
possible speaker damage.
