4-CHANNEL MULTI-CONFIGURATION AMPLIFIERS
INTRODUCTION
The 4503IQ is a multi-channel amplifier providing both power and flexibility. The
4503IQ is rated at 50 watts per channel into both 2 and 4-ohm loads. The amp
has an unregulated driven power supply for greater dynamic headroom. Each of
the four channels in this amplifier has its own dedicated 12dB/octave crossover.
The mode of operation for the amplifier is user selectable, for one of three
possible configurations - full range, bi-amp, or satellite. In the full range mode,
all four channels cover the entire music spectrum. The bi-amp mode dedicates
the front channels for a high pass output and the rear channels become the
subwoofer output, electronically crossed over at 80Hz. In the satellite mode,
both front and rear outputs are high pass outputs with the low pass RCA outputs
active providing subwoofer information for a separate amplifier. These are also
crossed over at 80Hz in the 4503IQ. The outputs of this amplifier have inverted
right channel outputs allowing the user to bridge the speaker outputs. Using a
mixed stereo/mono configuration on both front and rear outputs offers a
possibility of six-channel operation with this amplifier.
INSTALLATION
WIRING: Disconnect battery ground cable before making any power
connections.
RED WIRE: +12 volts - Connect directly to battery positive terminal and should
be fused within 18 inches of battery and another fuse where the connection to
the amplifier is made. Remember to use the proper size fuses. Do not install
power fuse until installation of amplifier is complete.
WARNING: USE OF OVERSIZED FUSES IS DANGEROUS AND WILL
DAMAGE YOUR AMPLIFIER.
