REFERENCE POWER SUPPLY DESIGN
The REFERENCE amplifiers employ an extremely efficient unregulated
pulse-
width modulated power supply. REFERENCE amplifiers from Soundstream are
rated at 12 volts but are designed to take advantage of the additional voltage
available when the vehicle is running.
The two major advantages of the
unregulated power supply are:
l
awesome dynamic power capabilities
l
added continuous power with higher voltages (see chart below)
Because of the dynamic properties of most music, all audio components 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.

amplifier is unique in its ability to switch between Coherent

and mixed mono output mode. The REFERENCE amplifiers are
zapable
of driving
a,complete

Mixed.Mono
configuration.
However, for lowest distortion, maximum output, and best sound
quality, we recommend that you use an electronic crossover and multiple
:hannels
of
amplificbtion.
f a single REFERENCE amplifier is to driie a subwoofer and satellite system,
Dassive
high and low pass crossovers will be necessary.
