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 ST-R50 tuner


 Quartz Synthesizer Tuner

You won't find a tuning knob on the ST-R50, because there's no more tuning capacitor to be rotated. All tuning is performed automatically and electronically by means of an voltage-sensitive varactor diode that employs a PLL quartz synthesizer for extra accuracy. Up to 10 MW, FM and LW stations may be programmed at random into the memory circuit and recalled instantly at the touch of a button. Manual tuning is also possible by holding in the up or down control until the desired station frequency is displayed. For optimum sound quality, a quadrature detector circuit with 6-element ceramic filters having flat group delay characteristics achieves a high sensitivity.

A newly developed IC in the limiter and detector reliability. A PLL IC in the MPX demodulation stage provides stable FM stereo switching unaffected by temperature, humidity or aging. The ST-R50 can also be combined with a couple of Aiwa optionals that make it perhaps the most convenient all-around versatile tuner available. When connected to the optional MT-50 timer unit, two On/Off cycles can be programmed at any time desired, and if the power remains on, preset stations may be changed automatically up to 6 times in a 24 hour period. The RC-R300 wireless remote transmitter/receiver unit (also optional) is capable of performing manual Up/Down tuning or selection of preset stations from up to six meters (20 feet ) away.

Features:

Adjustable synthesizer sensitivity control

3 or 4 digit tuned frequency display

FM muting and Hi-blend switches

5-point LED signal strength indicator
