TOPAZ
(Tracking Operation Pre-Amplifier Zone)
The
TOPAZ (Tracking Operation Pre-Amplifier Zone) circuitry solves
ground loop noise problems common to automotive amplifier design.
This innovative new development allows vastly improved isolation of
the input signal grounds from the power supply ground of the
amplifier. This is accomplished by allowing the source unit to control
the potential “environment” of the entire input structure or “zone” of
the amplifier. This process improves the noise rejection of the
amplifier by 30-40dB – an astounding 30-100 times better than
amplifiers without TOPAZ.
THE RESULT: Elimination of troublesome ground loop noise between
source and amplifier.

TRANS•ANA
(TRANSconductance Active Nodal Amplifier)
The
TRANS•ANA (TRANSconductance Active Nodal Amplifier) is a
circuit that allows the audio signal to pass through the amplifier at low
voltage. The signal is directly level-shifted to the fixed high voltage
rails via a pair of driver transistors. Signal linearity is assured by an
active node formed by the drive transistors at ultrasonic frequencies.
This allows amplifier performance similar to trans•
nova which is
highly stable and linear while utilizing the advantages of a non-
floating power supply.
THE RESULT: An extended frequency bandwidth accurately supplied
to the output stages of the amplifier.

Pass-Thru Output
The Pass-Thru output provides a convenient source for daisy-chain-
ing an additional amplifier without the need for extra RCA cables or
“Y” adapters. The Pass-Thru signal is derived from summing the Front
and Rear Left inputs to create a Left output, and summing the Front
and Rear Right inputs to create a Right output. When the amplifier is
used with 4-channel inputs, the Pass-Thru provides constant output
regardless of the source unit fade position. Additionally, the Pass-
Thru has an XCard that can be set for High-Pass, Low-Pass or Full Range.
THE RESULT: Constant non-faded output for adding woofer amplifiers.
