AUTO HIGH CURRENTTM POWER SUPPLY
The REFERENCE amplifier employs an extremely efficient
power supply (patent pending). This power supply circuitry automatically
customizes your amplifier for optimum efficiency and power output into virtually
any impedance load. When other brand amplifiers are driven at low impedances
they shut down, squash dynamics and power output (called
current limiting). or waste huge amounts of power (i.e., low efficiency). All of
which reduce the "real world" power the amplifier can produce in the car.

amplifiers to be one of two types of amps: either producing maximum power at
higher impedances (perfect for satellites) or at lower impedances (usually with
multiple subwoofers). This is done by letting the amplifier's power supply
continuously monitor the impedance of the load the amplifier is driving. If the
impedance drops too low, the power supply will automatically switch into High

mode. It will stay in this mode until the amplifier is turned off. The next
time it is powered up, it will be in the High
Unlike other amplifiers, Soundstream's REFERENCE amplifiers can be
configured to drive virtually any impedance and make maximum power! The
major advantages of this power supply are:
awesome dynamic power capabilities
l
added continuous power with higher voltages
l
increased amplifier efficiency and reliability

Because of the dynamic properties of most music; all audio components should
be able to react accordingly. Thanks to their unique power supplies, the
REFERENCE amplifiers can comfortably exceed their rated power for dynamic
portions of the music.
