Toshiba's System 15 microcomponents were introduced in 1978. Aurex was Toshiba's brand name for the japanese market but these micro components were sold with both Toshiba or Aurex logo worldwide. With less than half the size of usual components they set new performance level, in the meantime being elegant in appearance. The components of the Micro System 15 are:
SC-M15 - power amplifier (DC) incorporating a large toroidal power transformer, 40 W/ch (20 to 20,000Hz, 8 ohms), THD: less than 0.02%, Frequency response: 0Hc (DC) to 70,000Hz, BTL use is possible
SY-C15 - preamplifier: Dual FET DC equalizer amp and DC tone amp, THD: less than 0.01%, Frequency response: 10Hz to 100,000Hz
ST-F15 - FM tuner: Digital frequency synthesizer with auto/manual tuning and 10 station presets, Synthesizer accuracy: 0.0025%
PC-D15 - two motor cassette deck with IC logic control, two heads, direct loading and Dual Capstan Drive, Wow & Flutter: less than 0.04%, Frequency response: 20Hz to 18,000Hz
All components are 257 mm wide with a one piece diecast aluminium chassis for the power amplifier while the other components feature one piece front and top panel with additional aluminum panel at the back (instead of steel) and sides. All components were available in silver or in a more rare black version. This basic setup could be expanded with the following components:
ST-S20 - FM, AM, LW and SW Digital Quartz Synthesizer tuner
AD-15 - adres adapter. Toshiba's own noise reduction system in a separate box as an alternative to the Dolby circuit of the cassette deck
AT-12 - programmable Digital Timer
RM-15 - wired remote (5 m) for the cassette deck
AR-15HU - mini rack
AR-15VU - large rack on casters that could accomodate a SR-F45 turntable
SS-S12 - mini loudspeakers
SS-930S - large loudspeakers
