The Telefunken Mini-HiFi M1 system was introduced in 1980 and the same year it received the "Deutschen HiFi-Preis 1980" for design excellence. The heart of this system is the MA1 stereo integrated amplifier that can deliver 50 W/ch (4 ohm) with a THD of less than 0,1% at 1 kHz (45W/4 ohm). The all DIN plug systems allows connections of a tuner, two tape, auxiliary and phono source. The amplifier can be used with two pairs of loudspeakers, one set is for DIN speaker plugs while the other is of a push terminal type. All switches have red LED feedback while for power output there are two 12 segment LED power meters with meter range switch. The MT1 tuner is a Quartz Synthesizer model with digital display and 10 memory presets. This is a FM stereo - AM - LW tuner with manual tuning or direct frequency input model. Again, each button has red LED feed back. Next there is the MC1 cassette deck recorder. This is a two motor - two Sendust head, logic controlled model. It can handle all cassette types: normal, chrome, Fe-Cr and Metal (30-18000 Hz) The primary noise reduction system of this model is the High-Com system (74 dB chrome tape) invented by Telefunken. For further compatibility the deck features also a playback only Dolby system (hence the half Dolby logo) For manual tape recording there is a 12 segment/ch LED peak level indicator, and again all controls have red LED feedback. A detailed description of the similar HC 750 M model (introduced in 1982 as replacement for the MC1) can be seen in the 1001 Hi-Fi Collection. The recommended loudspeaker for this system was the Telefunken TLX 11 Professional.
