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.

Another example of TEAC dedication to delivering the finest possible quality in these amplifiers is the fact that each unit is individually calibrated for optimum performance.
In the A-X series amplifiers, the output stage idling current is determined by a precision trimmer rather than the usual fixed resistor. This is adjusted to provide optimum idling current - and therefore an absolute minimum of crossover distortion - during the final testing and inspection stage. You can rest assured that the amplifier you receive is fine-tuned to deliver super sound quality.
All-Mechanical Short-Path Signal Switching
Many modern amplifiers use semiconductor switches to control signal routing. These like any other electronic part, can degrade signal quality. TEAC has used only top-quality mechanical switches ensuring reliable, distortion-free signal routing. Furthermore, switches handling low level signals are positioned as close as possible to the corresponding rear-panel terminals to minimize the signal path length and are remotely controlled via the panel knobs. This means that noise and interference pickup is minimized for extra signal purity.
 Source Direct Switch
When you want an extra margin of signal purity, the Source Direct switch can be engaged to bypass the tone, balance, loudness controls, muting and subsonic filter controls, giving you the shortest, most direct signal path possible for all input sources.
Versatile Input and recording Capability
Independent input and Rec selectors let you monitor one source while simultaneously recording another. The Rec selector also offers tape-to-tape recording capability. The A-X5030 accept of 6 base input sources like; phono, tuner, CD, tape 1/DAT, tape 2, AUX, and additionally features Adapter/Tape 3 terminals that can be used to connect a third tape deck or an external adapter such as a graphic equalizer or surround processor. The A-X5030 also features a high-performance internal MC phono cartridge head amplifier and an MM/MC phono selector switch.
Heavy-Duty Binding-Post Speaker Terminals
Since speaker cables can have a significant effect on the sound, the TEAC amplifiers are equipped with heavy-duty binding-post terminals that will easily accept high-quality speaker cables while providing solid reliable contact.
