A smart looking receiver of incredibly compact dimensions, the AX-S50 puts out a lively 20 Watts per channel; its main appeal however is in its many sophisticated features, some so advanced they are just beginning to make their appearance in current full-sized receiver models.
For fully electronic one-touch tuning capability, the tuner section incorporates a quartz PLL synthesizer which selects the station either automatically or manually. Up to 10 stations may be programmed into the tuner's "memory" and selected at random, irrespective of band. An A/B switch (A=1-5/B=6-10) serves to reduce the number of switches for a cleaner control arrangement.
As in other Aiwa mini units, capable phono equalizer design promises high signal/noise ratio (80 dB) and ample overload capability (180 Mv at 1 kHz). The RC-R300 wireless remote control system (optional) can also be added to give the AX-S50 even more versatility; wireless remote functions include manual station tuning selection of preset radio channels and listening modes, up/down volume adjustment and operation of the SD-L60 cassette deck.
