DESIGN FEATURES
l
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 (8 gauge on the REF200).
l
High Power/High 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 Power, higher impedance loads (2 ohms mono and up).
l
Coherent
Stereo%illxed
Mono
selection for either “pure” stereo operation
or mixed mono for simultaneous stereo and mono.
l
Chassisink” Darlington Power Array - Soundstream’s “overbuilding” of the
output section incorporates multiple output transistors instead of a few for
faster, stronger power delivery. The transistors are sandwiched between the
circuit board and the
heatsink
in a design called
ChassisinkM
to ensure cool,
efficient amplifier operation.
l PowerGrid Power Supply Design
-
All power supply components are 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 it, guaranteeing minimal
noise.
l 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 out faster.
l Smart Thermal Rollback
-
Most amplifiers shut off when they get too hot.
In
the unlikely event the REFERENCE amplifier reaches 85” C, it will gradually
roll back its average power (without affecting the dynamics). Once the
amplifier has cooled off, it returns to full power output. If overheating should
continue, a second thermal sensing protection circuit will shut off the amplifier
if the heatsink reaches 95” C.
l Unregulated Power Supply - 4 ohm power ratings are measured at 12 volts,
meaning substantially greater output in the real world when the vehicle is
running, where voltages range from 13.2 to 14.4 volts.
l Fault Monitor LED on the front panel notifies you of blown power supply
fuses.
l
112
ohm Drive Ability - The REFERENCE amplifiers are designed to drive
virtually any load-all the way down to
l/2
ohm stereo (1 ohm mono).
l Dual Discrete Class A Drive Stages
-
Over six times the drive current of most
amps, which maintains performance into low impedance loads.
l Drive
DelayTM
Muted Turn-on/off Circuit - A unique circuit which completely
eliminates any amplifier-related turn-on/off noises.
l Flexible Input Sensitivity accepts voltages from 100
mV
to 2.5 V, permitting
maximum output from the amplifier with virtually any source unit.
l Balanced Input Design for added immunity to noise caused by component
and vehicle electrical system interaction.
l LSE.Q
(REFERENCESOO)
fully adjustable subwoofer equalization circuit
providing frequency and
leve/“Q”
adjustment for optimum subwoofer
performance. An adjustable subsonic filter protects woofers from damaging
low frequency information and maximizes output in a usable range.
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.

zapable
of driving
a,complete

configuration.
However, for lowest distortion, maximum output, and best sound
quality, we recommend that you use an electronic crossover and multiple
:hannels
