erminals
This unit is pr
ovided with gold-plated RCA input
jacks. Using RCA-RCA type patch cor
ds, connect
these inputs to the RCA outputs fr
om your head
unit. Low Level Input (High Impedance) This unit is pr
ovided with gold-plated RCA Output jacks.
Using RCA-RCA type patch cor
ds, connect these Outputs
to the RCA Inputs for your anyther amplifier
.
Low Level Output (High Impedance) Pr
otection LED Indicator
The pr
otection cir
cuitry in the amp will disable it if it
senses an input overload, speaker short cir
cuit, or
thermal overload conditions. Should this occur
, the
PROTECT LED will be illuminated. At that time, it is important that you check to determine what has caused the pr
otection cir
cuitry to become activated.
If the amp shut of
f because of a thermal overload,
allow it to cool down befor
