CONTROL & FUNCTIONS
1. Link-IN : Connect this RCA to Link-Out of MASTER Amplifier
Link-OUT : Connect this RCA to Link-IN of secondary (slave) Amplifier.
2. RCA Line Outputs: These RCA connections are used when connecting additional
amplifiers.
3. Low Level RCA Inputs: These inputs are for signal cables from a source unit.
Always use high quality shielded RCA cables.
4. Input Sensitivity Adjustment:
This control adjusts the amplifier's input sensitivity. Input sensitivity is variable from
300 Millivolts to 8 Volts. Turn the control clockwise to increase sensitivity. Turning the
control counter-clockwise will decrease sensitivity. This control is not a volume control
for the amplifier. The amplifier can be driven to full power with a wide range of signal
levels. A low level signal will require increased sensitivity for full power. A high level
signal will require decreased sensitivity.
5. Sub-Sonic Filter: For Sub-Sonic Frequency Adjustment from 20Hz - 55Hz.
6. Variable Low-Pass Filter : Set the crossover switch to LP when a
subwoofer is connected. Ensure the crossover frequency is set at 100Hz or below,
this feature is designed to filter out all mid to high frequencies that only.
- CD2800.1LX/4800.1LX : 40Hz - 300Hz
- CD80.5LX Sub Channel : 40Hz - 120Hz
7. Variable Bass Boost : This control adjusts the Bass Boost Gain for the amplifier's
speaker output.
- CD2800.1LX/4800.1LX : 0 to +12dB
- CD80.5LX: 0 to +18dB
8. Bass Frequency : This is vaviable control from 30Hz to 65Hz for Bass Boost.
9. Phase Switch: Master AMP must be set "0 " position. Slave Amp (secondary) must
be set "180 " position.
NOTE : When you try to link, you must set correct plase switch position :
MASTER AMP : Set to "0 "
Slave AMP : Set to "180 "
10. Config (MASTER/SLAVE) Select Switch
You must select this swtich according to Amplifier Role.
In case of MASTER AMP : Set to MASTER position.
In case of Slave (Secondary) : Set to Slave position.
11. LPL Remote Switch
Use the switch to activate or de-activate the (optional) bass controller.
12. LPL Remote Port
This port allows connection th the (optional) bass control.

CONTROL & FUNCTIONS
13. Input-selector switch : The sub outputs signal is a sum of the Ch1+2(Front) and
ch3+4(Rear) outputs. All three inputs will accept signal for use with a head unit with
three preamp outputs.
- When set to "1+2Ch" position, the front Inputs (Ch1+2) will provide signal for the
entire Amplifier.
- When set to "1+2Ch, 3+4Ch" position, both the front and rear inputs will accept
signal allowing the use of head unit fader.
- When set to "1+2Ch, 3+4Ch, SUB" all three inputs wil accept signal seperately for
use with a headunit with thre preamp outputs.
14. Band-Pass Filter(Only CD80.5LX)
To match the characteristics of the installed speaker
system, you can adjust the unwanted high and low
frequency sinals entering the speaker systems. By
setting the Band-pass control to select the cut-off
frequency (see the diagram), the speaker willoutput
only bandwitdth signals so you can get a clearer
sound image.
- BPF(LPF): Low pass filter-only (50Hz-4KHz)
- BPF(HPF): High pass filter-only (50Hz-4KHz)

15. Crossover: Adjust the crossover for your chosen installation method.(Only CD80.5LX)
- LPF: Low pass filter-only (50Hz-4KHz) / Sub Channel(40Hz - 120Hz)
- FULL: No filtering for speakers. Use with full-range speakers.
- HPF: High pass filter (50Hz-4KHz)
- BPF: Band pass filter
16. Power Indicator LED: This Blue LED will illuminate when the amplifier is turned "ON
Protection Indicator LED: This LED turns on if excessive current is detected in the
output stages.
This can be caused by any of the following:
- Any speaker cable shorted to the vehicles chassis (ground).
- Any pair of speaker cables shorted together (zero impedance).
- Shorted speaker voice coil(zero impedance).
- Combined speaker impedance is too low.
- Turns on due to excessive heat sink temperatures.
17. B- Terminal (Chassis ground): To avoid unwanted ignition noise caused by ground loops,
it is essential that the amplifier be grounded to a clean, bare metal surface of the
vehicles chassis.
18. B+ Terminal (Battery positive) : Due to the power requirements of the Amplifier, this
connection should be made directly to the positive (+)terminal of the battery.
For safety measure, install an in-line fuse Holder (not included) as close to the battery
positive (+) terminal as possible with an ampere rating not to exceed total value of
fuses on the amplifier.
19. Remote Turn-On Input : To remote turn-on wire of head unit. The amplifier is turned
"ON" remotely when the vehicle's head unit is turned "ON".
