REFERENCE POWER SUPPLY DESIGN
The REFERENCE amplifiers employ an extremely efficient unregulated

voltage available when the vehicle is running. The two major advantages of the
unregulated power supply are:

added continuous power with higher voltages (see chart below)
Because of the dynamic properties of most music, all audiocomponents should
be able to react accordingly. Thanks to their unregulated power supplies, the
REFERENCE amplifiers can comfortably exceed their rated power for dynamic
portions of the music.

PASSIVE AND ELECTRONIC CROSSOVERS
Your REFERENCE amplifier is unique in its ability to switch between Coherent
Bridged Mono, and Mixed Mono output mode. The REFERENCE
are capable of driving a complete
and satellite system in
the Mixed Mono
However,
lowest distortion, maximum
output, and best sound quality, we recommend that you
an electronic
crossover and multiple channels of
If a single REFERENCE amplifier is to drive a
and satellite system,
passive high and low pass crossovers will be necessary. Use the charts on
pages 7 and to determine the values of the crossover components.
