section through the use of two, four or 
six differential-balanced inputs.
Input connections are via up to three pairs of 
traditional RCA-type jacks.

If you wish to send six discrete channels into the

iInput Modew switch in the i6 Ch.w position. The 
amplifier will automatically combine the left and 
SJHIUiSub Ch.” input signals to mono. If you have 
only one channel of subwoofer signal available, 
it is acceptable to only use one of the “Sub Ch.” 
inputs, but for optimal gain, we recommend using a 
Y-adaptor and feeding both “Sub Ch.” inputs.
If you prefer to use only four channels of input

will derive its subwoofer channel signal from a 
sum of all four input signals. The bass will not 
fade when the signal is faded by the head unit 
from front to rear.
You may also choose to apply only two 
channels of input to deliver signal to all five 
amplifier channels. To do this, set the

4 will operate with the Channel 2 signal. The 
amplifier will automatically combine the main 
input signals to mono for the Subwoofer Channel.
 
Input Voltage Range: 
Input Voltage Range: A wide range of signal 
input voltages can be accommodated by the 
9%WTJOQVUTFDUJPO N7o7
This wide range is split up into two sub-ranges, 
accessible via the “Input Voltage” switch: 
“Low”: for preamp level signals
“High”: for speaker level signals

The “Low” position on the “Input Voltage” 
switch selects an input sensitivity range between

that the “Input Sens.” rotary control for each 
channel section will operate within that voltage 
window. If you are using an aftermarket source 
unit, with conventional preamp-level outputs, this 
is most likely the position that you will use.
The “High” position on the “Input Voltage” 
switch selects an input sensitivity range between

signals as well as speaker-level output from source 
units and small amplifiers. To use speaker-level 
sources, splice the speaker output wires of the 
source unit or small amplifier onto a pair of RCA 
cables or plugs or use the JL Audio ECS Speaker

+12 V Remote Turn-On: This is the preferred 
method for turning the amplifier on/off. The 
amplifier will turn on when +12 V is present at 
JUTiRemotewJOQVUBOEUVSOPGGXIFO7JT
switched off. This +12V remote turn-on signal is 
typically controlled by a source unit’s remote

wire. To connect the remote turn-on wire to 
the amplifier, first back out the set screw on the 
UPQPGUIFUFSNJOBMCMPDL VTJOHUIFTVQQMJFE
mm hex wrench. Strip 1/2 inch (12mm) of wire 
and insert the bare wire into the terminal block, 
seating it firmly so that no bare wire is exposed. 
While holding the wire in the terminal, tighten 
the set screw firmly, taking care not to strip the 
head of the screw and making sure that the wire 
is firmly gripped by the set screw.
If a source unit does not have a dedicated 
remote turn-on output, consider one of the 
following alternative turn-on options:
These methods are useful when a conventional 
+12 V remote turn-on signal is not available in a 
system. These allow you to operate the amplifier 
without having to locate a remote turn-on lead at 
the source unit, which can be very useful when 
interfacing the amplifier with OEM (factory) 
audio systems that do not use conventional +12 V 
turn-on leads.

delay to turn the system off after the signal is

for high-level (speaker level) signals, not for low-
level (preamp level) signals. The circuit senses the

The sensitivity of this circuit is designed for 
high-level (speaker level) signals, not for low-level 
(preamp level) signals. The circuit is tuned to 
react to signals at mid-range frequencies. This 
prevents false switching from signals created by 
moving loudspeakers that are in parallel with the 
amplifier’s input signal.
