The Maihak Reportofon MMK3 magnetic tape recorder was a self-powered machine designed for simple operation completely independent of mains power. It was enclosed in an elegant leather case which could be carried by handle or shoulder strap. A single five-position switch, located below the handle, controlled both the tape transport and the amplifier. The machine was driven by a powerful double wound governed spring motor, and the three midget valve amplifier by dry batteries.
The recording level was controlled by three fixed settings – (1) maximum gain, full frequency (2) gain attenuated by 9dB, full frequency (3) gain attenuated by 9dB with 400Hz HP filter. HT and LT batteries could be checked by a voltmeter mounted on the front panel which also had output terminals for reproduction.
