OWNERS MANUAL
Operation & Function
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 PDLC21.
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 PDLC21 with the output
level of your source unit.
G) Power Indicator - This LED indicates when the PDLC21 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.
