DESIGN FEATURES
Uncompromising Design and Construction including mil-spec glass epoxy circuit boards and high
current, custom gold-plated, solid aluminum connections that will accept up to 1/0 gauge power/ground
wire.
Auto High Current™ (subwoofer channel only) - Soundstream’s exclusive circuit which automatically
optimizes your amplifier to its particular application - High Current, low impedance loads (multiple sub-
woofers, less than 2 ohms) or High Power, higher impedance loads (2 ohms and up).
Continuously Variable Electronic Crossover - Continuously variable 4, 3 or 2-way crossovers with
12 dB/octave high pass and bandpass filters, and a 24 dB/octave subwoofer low pass filter. The six
non-subwoofer channels of the DaVinci amplifier can be used to drive almost any conceivable system!
Rear Channel De-emphasis - In 2 or 3-way mode, Channels 3/4 of the DaVinci amplifier can be
used for rear fill, and include a de-emphasis contour filter; a circuit based on theater surround
technology in which rear fill information is rolled off at 6 dB/octave with a -3 dB point at 7,000 Hz to
provide a more realistic listening experience.
PowerGrid™ Power Supply Design - All power supply components are located near one another, for
the shortest possible current path and are connected by thick, wide PCB traces, which ensure rapid,
high current delivery.
Ultra-Low ESR Capacitance Bank - Multiple miniature “stiffening” capacitors ensure rapid power
delivery for dynamic peaks. Multiple small input power capacitors are used to provide a lower ESR
(Equivalent Series Resistance), which means more power, faster.
Proprietary Vari-quiet™ Fan Cooling - Internal Heat Sinking and thermostat controlled fan system
maintain safe operating temperatures.
Smart Thermal Rollback™ - Most amplifiers shut off when they get too hot. In the unlikely event the
DaVinci 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.
Unregulated Power Supply - 4 ohm power ratings are measured at 12 volts, which means
substantially greater output in the real world when the vehicle is running, where voltages range from
13.6 to 14.4 volts. Dynamic capability of the unregulated power supply is vastly greater than that of a
tightly regulated power supply.
Fault Monitor LED on the front panel notifies you of a blown power supply fuse.
1 Ohm Subwoofer Drive Ability - The DaVinci subwoofer channel is designed to be stable into any
impedance, down to 1 ohm.
Seven Dual Discrete Class A Drive Stages - Over six times the drive current of most amps, which
maximizes linearity into any load.
Drive Delay™ Muted Turn-on/off Circuit - A unique circuit which completely eliminates
amplifierrelated turn-on/off noises.
