DESIGN FEATURES
l Uncompromising Design and Construction including glass
epoxy circuit boards and high current custom gold-plated solid brass
connections that will accept up to 4 gauge power/ground wire.
l

less than 2 ohms mono) or High Power, higher impedance loads (2
ohms mono and up).
l Coherent Mono selection for either “pure” stereo
operation or mixed mono for simultaneous stereo and mono.
l 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 in a design
called to ensure cool, efficient amplifier operation.
l
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.
. Ultra-Low ESR Capacitance Bank Multiple small input power
capacitors are used to provide lower ESR (Equivalent Series
Resistance), which means more power in and out
Smart Thermal 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
reaches 95” C.
l Fault Monitor LED on the top panel notifies you of blown power supply
fuses.

to 5.0 V.
. Differential Balanced Input Design for added immunity to noise
caused by component and vehicle electrical system interaction when
using unbalanced RCA inputs.
. True Balanced Input only) for professional-quality
performance and noise cancellation. The DIN plug carries
and signal information for left and right channels, audio ground, and
Vdc to operate the Soundstream or Balanced Line
Transmitters.
. Upgradable This feature allows RF remote control level
adjustment while the low pass filter on the amplifier’s internal crossover
is being used.
