OWNERS MANUAL
Operation & Function
Installation Guidelines
A)
Power Connections - These connections are for input power, chassis ground, and remote turn-on. Use a
minimum of 18 gauge wire for power and ground connections. The power wire should be fused with a
1 amp fuse.
B)
Input Gain Adjustment - This control matches the input level of your PDLC81 with the output
level of your source unit.
C)
Power Indicator - This LED indicates when the PDLC81 is powered on.
D)
Maximum Indicator - This LED indicates when the signal is at its maximum level before distortion occurs.
When the input “Gain” adjustment is set correctly and the source unit is at its maximum volume this LED
should flicker intermittently.
E)
Summing Indicators - These LED’s indicate when a channel is being summed with the main channel.
F)
RCA Outputs - These RCA output jacks provide a full range signal to your amplifier. Channel 4
has one additional feature. When there is no signal present on Channel 4, Channel 3’s
input will automatically be sent out Channel 4.
G)
AUX Input - This RCA input jack allows you to connect an additional source to the PDLC81 such as an iPod
H)
Remote Control - This port is for the dual function remote control (Included). The first
function is source selection. Pushing the control knob in will toggle the PDLC81’s input between
the AUX and Main channels. The second function allows the user to control the level of Channel 4’s
output up to the maximum adjustment level set on the PDLC81. This control does not add any additional
gain, it only attenuates the level at which the PDLC81 was set.
I)
High Level Inputs - This terminal block allows for a high level left and right channel signal input from
the source unit. Use this if your source unit does not have RCA outputs.
A)
Power Connections - These connections are for input power, chassis ground, and remote turn-on. Use a
minimum of 18 gauge wire for power and ground connections. The power wire should be fused with a
1 amp fuse.
B)
RCA Outputs - These RCA ouput jacks provide signal to your amplifer.
C)
Low Level Inputs - These RCA input jacks allow for a low level left and right channel signal input
from the source unit.
D)
Input Switch Selector - This switch is used to select the input of the PDLC81.
There are two possible inputs, the RCA position selects the low level RCA input (0-4V) and the Speaker
position selects the high level input.
E)
High Level Inputs - This terminal block allows for a high level left and right channel signal input from
the source unit. Use this if your source unit does not have RCA outputs.
F)
Input Gain Adjustment - This control matches the input level of your PDLC81 with the output
level of your source unit.
G)
Power Indicator - This LED indicates when the PDLC81 is powered on.
H)
Maximum Indicator - This LED indicates when the signal is at its maximum level before distortion occurs.
When the input “Gain” adjustment is set correctly and the source unit is at its maximum volume this LED
should flicker intermittently.
INSTALLATION PRECAUTIONS
• Always mount the unit in a fashion so that it can be easily accessible for making adjustments.
• Avoid mounting the unit to subwoofer enclosures or high vibration areas.
• Do not cover the unit with carpet or any other material.
• Do not mount the unit in the engine compartment or anywhere that it will be subject to high temperatures,
(ie, direct sunlight or heater) moisture, dust or dirt.
• Use rubber or plastic grommets to protect wires when routing them through metal.
• Always keep signal wires away from high current power wires.
• The ground connection should always be the first connection made.
