Zero Feedback

Feed forward
driver design

Thermic
Servo Loop

The Zero Feedback design
of 3026A greatly Increases
the signal capamty of the
active stages.

Usually feedback is applied
to reduce overall distortion
and linearity errors.

Our unique design offers

all the advantages of zero
feedback Without any
sacrifice in linearity or raised
distortion levels.

The feed forward circuitry
eliminates the on-resrstance
in the output transistors.

This results in extremely
low output impedance -

all through the audio hand
up to several hundred kHz
- assuring full control over

all elements in the speakers.

This results in highly detailed
and accurate midrange and
high-end 7 hardly matched
by other amplifier desrgns.

To control DC stability
servo loops are required.
Usually this is done
electronically With a lowpass
filter and a negative feedback
loop injecting Its control

signals into the audio path.
This Will degrade sound
quality.

The Tandberg Thermic
Servo Loop controls, in a

unique way, by means of
temperature to achieve
0 DC - With absolute no
interference to the audio
signal.
