The result is a self-regulating, distortion reducing process. Unfortunately, if the amount of feedback employed is too great, the input stage becomes saturated and produces transient intermodulation distortion (TIM). TIM is audible as a harshness similar to that produced by crossover distortion. The Citation 16 reduced TIM to very low levels. The Citation 16 (series A) diminishes it still further. Feedback is reduced and is set at a level which achieves extraordinarily low distortion simultaneously avoiding input stage saturation. TIM is dramatically reduced. 9p u! lanai awl% 0 -- 00 -- 70 11( 5,000 Hz 10,0001 1z •equency in i lertz 15,000 Hz

One

the
major
developments
in

fidelity
design
was
the
discovery
of
the
beneficial
effects
of
applying
negative
feedback
to
amplifier
circuits.
The
result
is
a
self-regulating,
distortion
reducing
process.
Un-
fortunately,
if
the
amount
of
feed-
back
employed
is
too
great,
the
input
stage
becomes
saturated
and
produces
transient
intermodulation
distortion
(TIM).
TIM
is
audible
as
a
harshness
similar
to
that
produced
by
crossover
distortion.
The
Citation
16
reduced
TIM
to
very
low
levels.
The
Citation
16
(series
A)
diminishes
it
still
further.
Feedback
is
reduced
and
is
set
at
a
level
which
achieves
extraordinarily
low
distortion
simultaneously
avoiding
input
stage
saturation.
TIM
is
dramatically
reduced.
