END PANEL LAYOUTS
PA D4000.4 Line Level Inputs/Controls
1. Status LEDs (on top of amplifier): Power and Protection— Power will illuminate to indicate
the amplifier is on and operating normally; protection will illuminate if the amplifier shuts down
due to short circuit, DC offset, or overheating detected by onboard protection circuitry.
Rear Controls
2. Rear Line Level Inputs—
accepts line level input from the rear channels of a head unit.
3. Rear Level Control —Adjusts the gain of the rear channels to match the output voltage
from your head unit.
4. (a) Rear High-Pass Frequency Button— When FREQ x 10 is engaged, the crossover’s
range increases to 200Hz - 4kHz.
(b) Rear HPF Control— Adjusts the high pass filter frequency to attenuate frequencies
below the setting on the control.
5. (a) Rear Low-Pass Frequency Button— When FREQ x 10 is engaged, the crossover’s
range increases to 500Hz - 5kHz.
(b) Rear LPF Control— Adjusts the low pass filter frequency to attenuate frequencies
above the setting on the control.
6. Rear BPF, FULL, HPF Switch— Selects full range, high pass filter, or band-pass filter. The BPF setting
allows you to use both the high pass filter and low pass filter, and it is for use with mid-range drivers.
The FULL setting does not attenuate any frequencies and is for full range speaker systems. The HPF
setting attenuates low frequencies and is used with mid-range speakers and tweeters.
7. Channel Mode Switch (ST/4Ch)— Set the switch to 4CH if you are using four channel outputs from your head
unit to the FL, FR, RL, RR inputs on the amplifier. Set the switch to ST (stereo) mode if you are using two channel
outputs from your head unit. In the ST position, the amplifier will take the signal input to the FL and FR inputs
and send the same signals also to the RL and RR amplifier channels.
8. Front BPF, FULL, HPF Switch— Selects full range, high pass filter, or band-pass filter. The BPF
setting allows you to use both the high pass filter and low pass filter, and it is for use with mid-range
drivers. The FULL setting does not attenuate any frequencies and is for full range speaker systems.
The HPF setting attenuates low frequencies and is used with mid-range speakers and tweeters.

PA D4000.4 Power Inputs/Speaker Outputs
1.
GND (Ground)— Connect this terminal directly to the metal chassis of the vehicle, using the shortest

wire. The chassis connection point should be scraped free of paint and dirt. Use only quality crimped and/or
soldered connectors at both ends of this wire. DO NOT connect this terminal directly to the vehicle battery
ground terminal or any other factory ground points.

Connect it to the remote turn on lead of the head unit.
3. +12V Power— Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal
of the vehicle battery or the positive terminal of an isolated audio system battery.
WARNING: Always protect this power wire by installing a fuse or circuit breaker of the appropriate

4. Fuse— These fuses (40A & 35A) protect the amplifier against internal electrical damage and are meant
to protect only the amplifier. All other power connections should be fused at the power source.
5. Speaker Output— Connect the speakers here
6. Terminal Adaptor —The adaptor enables the use of cable up to 0000AWG
