ZRX500.2 / ZRX1200.2 2-CHANNEL AMPLIFIER APPLICATIONS
4. Line Level:
This is the most basic application for the ZRX Series 2 channel amplifiers.
Refer to the section
“Setting up systems after installation for best performance”
1. Interconnect cable checklist:
Connect the
LINE INPUTS
to the Radio/CD with good quality RCA cables.
NOTE: Minimum final loudspeaker impedances:
2. Crossover Switch:
4 & 2 Ohms stereo mode or 4-Ohms mono mode
The
X-OVER
switch must be in the

position.
This amplifier will not do 1 Ohm stereo or 2/1 Ohm mono operation.
3. Crossover frequency control checklist:

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

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 -.
