signal the auto turn-on feature is active. With the auto turn-on active, the
REM becomes an output to turn on/off up to two additional amplifiers or
other accessories.
Pass Thru
The pass-thru RCAs are passive, including full input signal range and auto
turn-on functionality when active. When utilizing Pass Thru jacks, up to
two additional amplifiers can be connected together.
Infrasonic Filter
The 28Hz 12dB/octave infrasonic filter limits the amount
of low frequency information going to the woofer.
NOTE: We recommend using the infrasonic filter when using vented en-
closures with this amplifier.
Punch EQ
This works along with the crossover switch on the amplifier. When set to
Low-Pass (LP) operation, this is a variable Bass Boost. When set to High-
Pass (HP) operation, this is a variable Mid-Bass and Treble Boost. When
set to All-Pass (AP) operation, both the Bass and Treble frequencies are
boosted. Set this to your personal preference while listening to the system.
Over excursion and subsequent damage may
occur at high levels of boost.
Remote Punch Level Control
(Option)
NOTE: Previous (prior to 2013) PEQ, Punch Bass and Para-Punch
remotes will not work with these amplifiers.
Quick Install:
1. Using the screws supplied, install the mounting clip.
2. Slip the remote onto the mounting clip until it snaps into place.
3. Route and connect the cable to the remote and amplifier.
Operation:
4. When connected, the “Level Control” is linked and allows you to
remotely control the output level of the amplifier from the dash or
center console.
NOTE: Use the instructions that came with the remote for a variety of
Adjusting Crossover Frequency
Do the following individually for each
channel.
Placing the crossover switch in the HP
position sets the amplifier to the High
Pass mode, enabling frequencies above the cut-off point to pass, adjust-
able between 50-250Hz.
Placing the crossover switch in the AP position sets the amplifier to the All
Pass mode, preventing any crossover adjustment, allowing all frequencies
to pass.
Placing the crossover switch in the LP position sets the amplifier to the
Low Pass mode, enabling frequencies below the cut-off point to pass,
adjustable between 50-250Hz.
Turn the crossover adjustment knob all the way down. With the system
playing, turn the crossover adjustment knob up slowly until the desired
crossover point is achieved.
2/4 Channel Switch
Setting this switch to the 2CH. position, switches
the inputs to a 2-channel mode, allowing con-
nection to only the front inputs with a 4-channel
output.
Output controls function the same as if the amplifier was in 4-channel
mode.
All “ACTIVE” inputs must have RCA jacks connected.
Switch in 2CH. position,“ACTIVE” - Front channel inputs only.
Switch in 4CH. position,“ACTIVE” - All Front and Rear channel inputs.
NOTE: When connecting to the 4-Channel inputs, be sure to route both
front and rear RCA cables tightly together.
Subwoofer Input Switch (P1000X5)
Setting this switch to the Off position, utilizes the front
inputs, allowing connection to only the front inputs with
a subwoofer output. Setting this switch to the On position
uses sub input.
Output controls function the same as if the amplifier was in 5-channel
mode.
All “ACTIVE” inputs must have RCA jacks connected.
Switch in FRONT. position,“ACTIVE” - Front channel inputs only for sub
output. Switch in SUB position,“ACTIVE” - Sub inputs for sub output.
NOTE: When connecting to the 5-Channel inputs, be sure to route front,
rear and sub RCA cables tightly together.
High Level Input
Connect from source signal by plugging into the RCA input jacks at the
amplifier. The input sensitivity ranges from 150mV-12V to accommodate
signal from high-level(speaker) input. When utilizing high-level for input
