◆ 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.
◆ 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 ampli-
fier 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.
◆ Bass EQ
The Bass EQ helps correct for acoustical deficiencies in the listening
environment. A unique potentiometer that controls bass compen-
sates for the lack of low frequencies present in most car environ-
ments. Unlike a conventional tone control, the Bass EQ corrects the
specific problem of poor low bass response.
THE RESULT: Provides better low bass response.
