BOLTAR / COLOSSUS PRO 2-CHANNEL AMPLIFIER APPLICATIONS
FULL RANGE STEREO
This is the most basic application for the BOLTAR & COLOSSUS PRO
2 channel amplifiers.
1. Interconnect cable checklist:
Connect the LINE INPUTS to the Radio/CD with good quality RCA cables.
2. Crossover Switch:
The X-OVER switch must be in the FULL position.
3. Crossover frequency control checklist:
FULL RANGE
STEREO LINE INPUT
MONO
This application illustrates the basic mono bridging method for all Hifonics
amplifiers.
Interconnect cable checklist:
A MONO signal source is suggested, 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 not necessary, but recommended, 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
RIGHT +, and its negative terminal to LEFT -.
