What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Teac AE-200

 The Teac model AE-200 incorporates for amplification a "differential circuit" widely used in computers and instrumentation data recorders which are also manufactured at the Computer Products Division of Teac. The result is an extremely wide dynamic range and virtually flat response extending well into the low frequency range.

For ultimate performance of the differential amplifier, a dual power supply system is employed in the Teac model AE-200 (+40 volt, -0 volt, -40 volt). This permits elimination of condensers from the output circuit, to provide automatic compensation of delicate current balance and virtually flat response. This is particularly evident in the low frequency range.
In addition to an ordinary protective circuit, a special thermo-breaker is provided in the Teac AE-200 for complete protection from accidental damage to the amplifier by short circuits in the speaker wiring. Should the breaker be tripped by a short circuit, the cause should be eliminated and the reset buttons depressed to restore operation of the amplifier.
 The Teac model AE-200 gives you 50 clean watts per channel at 8 ohms, and 60 watts per channel at 4 ohms. This is the amplifier's full rated power (continuous sine wave) with a total harmonic distortion of an amazing 0,5% within 0,5 dB. Teac has no need to rely on misleading, inflated so-called "music power" specifications. The virtually undistored power AE-200 delivers is more than enough to drive any speaker system.

Unique concealed Panel Control. Drop the panel lid and Presto. A complete stereo control is revealed with every relinement to please the most discriminating audiophile. Shut the panel and your Model AE-200 is a masterpiece of modern design. Controls in frequent use are always visible and easily accessible. Infrequently used controls are concealed behind the beautiful Eurasian wood panel.

Phase reverse switch. A very convenient  combination switch for phase checking of multichannel speaker systems by reversing polarity or electrically interchanging the left and right speakers. Also, either channel speaker can be individually switched on.

Balans Check. A very unique circuit utilizing the differential amplifier characteristic. When the balance in output of both L and R channels is perfect, they will be canceled and no sound will be heard from the speaker. A signal source applied in parallel to the input is most convenient at making this check.
