TEAC AT-100
New
Multiplex Channel Separation Circuitry
New low
level multiplex sensitivity provides clean clear stereo operation with only a
10 µV input. The all new multiplex amplifier provides complete channel
separation (40 dB at 1 kHz, 100% modulation) even where stations are closely
located in frequency and physical proximity to each other.
Sharply
Selective-Stable IF circuitry
The FM IF
stages of the AT-100 incorporate 6 element ceramic filters for precise exact
bandpass shaping. Sharply selective, unaffected by humidity or aging, they
provide many years of trouble free operation.
Noise Free
FM Receprion
A total of
10 limiting stages are employed in the AT-100 (4 diode limiter stages, 6 transistor limiter stages) to provide complete freedom from pulse noise reception
from auto ignition systems, electrical appliances and atmospheric disturbances.
Advanced
Solid State Front End
A dual gate
MOS type field effect transistor and a junction type FET are used in the FM RF
section to provide maximum gain and sensitivity, high selectivity and the
maximum in interference rejection.
Precision
Tuning System
The AT-100
tuner employs a 4 gang, linear graduation tuning condenser coupled to a
weighted tuning system. The dial features a linear tuning display across the
entire tuning band. Independent signal strength and channel center tuning
meters make precision tuning remarkably simple.
Interstation
Noise Muting
An extremely
sensitive muting circuit completely eliminates interstation (white) noise when
tuning between stations. Switch controlled from the front panel, the muting
circuit can be disabled for tuning extremely weak (fringe area) stations.
Dual Output
Facility
The AT-100
is provided with both fixed and variable output level jakc thus is compatible
with any currently available amplifying system.
Remarkable
Performance Specifications - Moderate Cost.
The overall
sensitivity and selectivity of this superb tuner provide clear distortion free
FM stereo reception even if fringe areas at a surprisingly moderate cost.
Regulated
Stable Power Supply
A completely
solid state, closely regulated power supply contributes to the stability of
operation of the At-100. prevents station drift even in areas where line
voltage is not constant.
