Teac AT-100

 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.
