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.

Aiwa SA-A60 amplifier

Amplifier, tuner and cassette deck; all identically styled, all withexciting performance.

The SA-A60 integrated amplifier typifies a new breed of space-saving mini component designed for powerful, low distortion sound.

 

Dynamic Super Loudness for improved bass reproduction

Mere tone adjustment or use of conventional loudness compensation can only enhance bass signals at the expense of affecting listening quality in midrange frequencies as well. The new DSL circuit in the SA-A60 puts back electronically what the speaker itself is unable to do strucurally, DSL performs at its best at quiet listening levels; its effect is automatically attenuated in response to output volume, keeping tone quality natural whether at low, medium or high volumes. Whether with bookshelf size or larger floor standing speakers, every type of music stands to benefit from this exciting new achievement.

 

Built-in MC cartridge head amp

Just press in the front panel switch and you can enjoy the distinctive tone quality of Moving Coil phono cartridges on the SA-A60 without the need for expensive outboard head amplifier units. MM cartridge performance is outstanding as well; the precision phono equalizer boasts a superb 85 dB Signal-to-Noise Ratio and RIAA deviation within ±0,2 dB from 20 to 20,000 Hz

Stabilized power supply

For full power performance with extra stability, the 30 watt per channel power stage incorporates a heavy-duty toroidal core transformer. Power ICs are protected by a new type of temperature sensitive circuit designed to guard against overheating.

 


Plus Features:

Wireless remote control terminal

7-step peak power output display

-20 dB muting switch

Low cut filter

LED mode setting indicators
