(Rapid-Use Branched Impulse) Our new

power supply 

 

 during-low frequency re-

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.

 (Stabilized Apex Current Topology) Reduces power

supply stress by 

 

 channels usually de-

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.

Three types of protection for 

amplifiers;

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 elec-
trical (turn on lead) and battery ground.
Thermal protection. Will put the amplifier into thermal rollback or
shut the amplifier down in extreme thermal conditions.

Provides focused subwoofer boost and

routes wasted subsonic power to the audible bandwidth. The

   302 have the variable version of Hawkins Bass

Control which allows you to boost bass from 0 to 

 at 45Hz. A

built-in subsonic filter at 45Hz helps protect the speakers. The

 contains the fixed Hawkins Bass Control which

allows you to boost bass 6dB at 45Hz. A built-in subsonic filter
at 45Hz helps protect the speakers.

 The 2nd and 3rd order harmonic

peaks are critically aligned 

to fundamental peaks at 

low frequen-

cies. This produces tighter, more accurate bass reproduction.

 Amplifier section now powers up 2   3

seconds after power supply eliminating turn on pops. Turn off
process is reversed. Amplifier section turns off first, followed by

power supply.

 Power grid is now evenly

distributed between primary and secondary power supplies, pro-
viding greater dynamics and improved RF filtering.

 Allows 

user to

match the amplifier to the load being driven allowing greater sys-

tem flexibility and greater output.

 All transistors are sandwiched between the cir-

cuit board and the 

 to provide cool efficient amplifier

operation in a smaller package.

Eliminates ground loops

related noise in the audio.

Built-in 

way electronic crossover is designed to send either high or low
pass information to the amplifier. 

 

 and

(202   302 only): 300mV to

5V input sensitivity. Separate left and right level controls allows

user to optimize 

system 

level control.

A 

adjusts for linear performance in low impedance loads.

Allows for stealth installation of RCA,

Balanced Line, Speaker and Power wiring.
