3. Crossover frequency control checklist:
This is the most basic application for the GTR Series 2 channel amplifiers.
N/A for full range operation.
1. Interconnect cable checklist: 4. Line Level:
Connect the LINE INPUTS to the Radio/CD with good quality RCA cables.
Refer to the section “Setting up systems after installation for best performance”.
2. Crossover Switch:
The X-OVER switch must be in the FULL position.
NOTE: Minimum final loudspeaker impedances:
The MODE switch must be in the STEREO position.
4 &-2-Ohms stereo mode or 4-Ohms mono mode
This amplifier will not do 1-Ohm stereo or 2/1-Ohm mono operation.

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 RIGHT +, and its negative
terminal to LEFT -.
