Gtr1100.2 2-Channel Amplifier Applications - Crunch GTR1100.2 Manual

GTR1100.2 2 CHANNEL AMPLIFIER APPLICATIONS
FULL RANGE STEREO
This is the most basic application for the GTR 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.
The MODE switch must be in the STEREO position.
FULL RANGE
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 RIGHT +, and its negative
terminal to LEFT -.

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
This amplifier will not do 1-Ohm stereo or 2/1-Ohm mono operation.
Switch setting checklist:
- The X-OVER switch must be in the LPF position.
Crossover frequency control setting checklist:
LPF: 80Hz (11 o'clock)
Minimum final loudspeaker impedance:
- 4-Ohms mono.
