RUBITM(_Rapid-Be _Branched -Impulse)

This new proprietary power sup­ply 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 frequen­cies. Also, greater reserve gate power is stored for low voltage condi­tions that occur during extreme conditions.

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.

Dynamically Optimized Power Grid

TM.Power grid is evenly distrib-

uted between primary and secondary power supplies, providing greater
dynamics and improved RF filtering.

STACTTM (STabilized

Apex

orrent _Topology)

Reduces power supply
stress by 50%. Typical designs degrade 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 pro­duces no even-harmonic distortion itself and all preamplifier circuitry is
run completely in-phase, no even harmonic distortion phase reversal
occurs.

TridentTM

Protection Topology

provides three types of protection:

1. Output protection against short circuits or improper loads.

2. Ground fault detection: Shuts down the amplifier when a significant
voltage (> Welts) fluctuation occurs between electrical (turn-on lead)
and battery ground.

3. Thermal Protection: Puts the amplifier into thermal rollback or shuts
the amplifier down in extreme thermal conditions.

subwoofer control circuit included with the

plifiers. It is capable of removing subsonic en­ergy in program material while boosting
subwoofer frequencies. The circuit consists of
two controls. One adjusts the frequency of op­eration and the other adjusts the range of boost.
With both controls adjusted fully counter-clock-

wise, no boost is applied and the amplifier is flat

in response down to 20 Hz.

FIG. 1 BASS CONTROL

The frequency control (Hz)

adjusts
the starting point of the subsonic fil­ter. On the RUBICON502,702 and
1002, the high pass filter has two fre­quency ranges. When the bass con­trol switch is set to “SUB SONIC”,
the high pass filter frequency can be
adjusted from 13 Hz up to a maxi­mum of 30 Hz. In this setting, no
boost “Q” control is available. This
control is useful for setting the low­est frequency that your subwoofer
will see (see figure 1). When the
bass control switch is set to
“HAWKINS BASS CONTROL”, the
high pass filter frequency can be ad-

justed from 30 Hz to a maximum of

70 Hz. In this setting, there is an
available boost control of 0 to +9

Application

Subwoofer drivers in general have
excellent power handling character­istics over their operational band­width. This bandwidth is determined
by many factors, including driver de­sign, and enclosure type. It is pos­sible 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 effective­ness of the Hawkins Bass Control on woofer excursion in a vented enclo­sure. 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.

Adjustment

An easy method of optimizing your existing subwoofer enclosure with

Hawkin’s “Hz” control is as follows.

1.

Adjust frequency and boost control to full CCW position.

2.

Set the bass control switch to “HAWKINS BASS CONTROL”.

3.

While listening to music with strong bass content at a moderate level,
slowly adjust frequency control clockwise. Listen for a reduction of bass

response. Now, rotate frequency control slightly backwards. This serves

the purpose of removing the “subsonic” bass energy.

With Soundstream’s Hawkins Bass
Control, the boost and frequency con­trol can provide virtually any combina­tion of boost and cut to suit your de­signs. So, Hawkins Bass Control can
provide the “tailoring” needed for any
type of “assisted” design and any
woofer in any type of installation.
