Output Clipping Indicators indicate clipping on the output stage of
the amplifier. Monitoring the clipping indicators allows the user to achieve
maximum Sound Pressure Level without clipping the amplifier.
This new proprietary power sup-
ply topology eliminates “power sags” during low frequency reproduction
by rapidly increasing the duty cycle, stabilizing the power supply and
allowing it to deliver the power required when reproducing low frequen-
cies. Also, greater reserve gate power is stored for low voltage condi-
tions that occur during extreme conditions.

stress by 50%. Typical designs degrade the stereo image due to phase
reversal of even-order harmonic distortion that occurs between the in-
verted 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 preamplifier circuitry is
run completely in-phase, no even harmonic distortion phase reversal
occurs.

Subwoofer drivers in general have
excellent power handling character-
istics over their operational band-
width. This bandwidth is determined
by many factors, including driver de-
sign, and enclosure type. It is pos-
sible to overdrive any subwoofer
driver by sending powerful signals
outside of its operational bandwidth. These potentially damaging signals
can be removed by adding a subsonic filter. Figure 5 shows the effective-
ness of the Hawkins Bass Control on woofer excursion in a vented enclo-
sure. The woofer travels 7.5 mm at 10 Hz. With Hawkins Bass Control
properly adjusted, this excursion can be reduced to less than 1 mm. This is
of great benefit to lowering woofer distortion and increasing output.
