FULL RANGE STEREO
This is the most basic application for the XXV Series 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:
N/A for full range operation.

STEREO LINE INPUT
FULL RANGE MONO
This application illustrates the basic mono bridging method for all HiFonics
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 standalone, or built into a head
Important:
unit or equalizer.
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 -.

Switch setting checklist:
The AMPLIFIER X-OVER switch must be in the FULL position.
Crossover frequency control setting checklist:
N/A for full range operation.
TIP:
If you are using the mono sub bass output of an active crossover, there is
nothing wrong with switching in the low pass filter in these amplifiers for a
steeper low pass roll-off.
Caution: This amplifier is not capable of 1 Ohms stereo or 2 Ohms bridged.
