Design Features - Soundstream REFERENCE 300SX Owner's Manual And Installation Manual

CONGRATULATIONS!
You now own the REFERENCE Amplifier, the product of an
uncompromising design and engineering philosophy. Your SoLndstream
REFERENCE amplifier will outperform any other amplifier in the world.
To madmize the pedorrnance of your system, we recommend that you
thoroughly acquaint yourself with its capabilities and features. Please retain
this manual and your sales and installation receipts for future reference.
Soundstream amplifiers are the result 01 American craftsmanship and the
highest quality control standards, and when properly installed will provide
you with many years of listening pleasure. Should your amplifier ever need
service or replacement due to theft, please record the following information,
which will help protect your investment.

DESIGN FEATURES

. Uncompromising Design and Construction - including mil-spec glass
epoxy circuit boards and high current custom gold-plated solid brass
connections that will accept up to 4 gauge power/ground wire.
. Hlgh PowerRligh Current CapabIlity - Soundstream's exclusive circuit
which permits customization of your amplifier to its particular
application-high current, low impedance loads (multiple subwoofers, less
than 2 ohms mono) or High Paver, higher impedance loads (2 ohms mono
and up).
. Coherent StereoTYIMlxed Mono - selection for either "pure" stereo
operation or mixed mono for simultaneous stereo and mono.

for faster, stronger power delivery. The transistors are sandwiched
between the circuit board and the heatsink in a design called Chassisir&TM
to ensure cool. efficient amplifier operation.
located near one another. connected by thick. wide PCB traces. which
ensures rapid, high current delivery. The entire power supply is isolated on
one side of the circuit board while the audio stage is located opposite if,
guaranteeing minimal noise
Ultra-Low ESR Capacitance Bank-Multiple small input power capacitors
are used to provide a lower ESR (Equivalent Series Resistance), which
means more power
in and auf faster.
Thermal Rollback - Most amplifiers shut off when they get too hot.
In the unlikely event the REFERENCE300sx amplifier reaches 85" C, it will
gradually roil back its average power (without affecting the dynamics).
Once the amplifier has cooled off, it returns to full power oulput. If
overheating should continue, a second thermal sensing protection circuit
will shut off the amplifier if the heatsink reaches 95" C.
Unregulated Power Supply 4 ohm power ratings are measured at 12
volts, meaning substantially greater oulpui in the real world when the
vehicle is funning, where voltages range from 13.2 to 14.4 volts.
