STEREO LINE INPUT
MONO
This application illustrates the basic mono bridging method for all Crunch 2 channel
amplifiers.
Interconnect cable checklist:
A MONO signal source is required, such as would be available from the mono sub bass
output of an active crossover, whether stand alone, or built into a head unit or equalizer.
Important: Do not be tempted to connect the hot, or positive outputs, from any source
together to obtain a mono signal, as this could very well damage the output stage of that
source.
It is necessary to feed the SAME signal to both left and right inputs via a Y-adapter RCA
cable. Connect the mono speaker positive terminal to the LEFT +, and its negative
terminal to RIGHT -.

FROM MONO SOURCE
The HIGH LEVEL inputs are used when the radio/CD player does not have RCA cable outputs. You can connect the radio/CD player speaker wires directly
to the amplifier via the high Level Inputs.
3. Crossover frequency control checklist:
N/A for full range operation.
4. Line Level:
Refer to the section "Setting up systems after installation for best performance".
NOTE: Minimum final loudspeaker impedances:
4 &-2-Ohms stereo mode or 4-Ohms mono mode
