Aiwa ST-R10 tuner

AM/FM Stereo Tuner

In addition to its wide frequency response, high selectivity and beautifully defined FM stereo channel separation, the St=R10 features two newly developed features designed to bring out the unit's full potential whether indoors or out. First, a special Input Noise Blanking System effectively suppresses interference from auto ignition systems. And second, the ST-R10 incorporates a unique new Auto Blend Circuit which automatically adjust the FM MPX stage as required to prevent deterioration of channel separation.

Tuning has also been facilitated; Aiwa has replaced the usual dial pointer with a center tuning indicator composed of two red and one green LED, which wink to indicate tuning to the strongest reception point.

Features:

PLL MPX circuitry for stable FM stereo reception

FM muting/AFC switch

75/300 ohms antenna terminals

FM stereo LED indicator

Auto muting level adjustor built-in
