DESIGN FEATURES

RUBI

Power Supply (Rapid-Use Branched Impulse) Our new

power supply eliminates”power
production by rapidly increasing the duty cycle, stabilizing the
power supply and allowing it to deliver the power required when
reproducing low frequencies. Also, greater reserve gate power
is now stored for low voltage conditions that occur during ex-

treme conditions.

STACTTM

supply stress by
grades the stereo image due to phase reversal of even order
harmonic distortion that occurs between the inverted channels.

In the STACT design inversion is done at the power amplifier

drive stage. Since the fully symmetrical power amplifier pro-
duces no even harmonic distortion itself and all preamp circuitry

(which does produce even harmonics) is run completely in phase,
no even harmonic distortion phase reversal occurs.

1.

Output protection against short circuits or improper loads.

2. Ground fault detection. Shuts down the amplifier when a
cant (5 volt or greater) voltage fluctuation occurs between elec­trical (turn on lead) and battery ground.
Thermal protection. Will put the amplifier into thermal rollback or

shut the amplifier down in extreme thermal conditions.
