The network reel tape recorder "MAG-8" since 1950 produced the Moscow plant "Gosteasvet". Semi-studio reel tape recorder "MAG-8" is based on the serial tape recorder "MAG-3". The tape recorder '' MAG-8 '' has three speeds of pulling the magnetic tape; 76, 38 and 19 cm / s. It is designed to record and play already pre-recorded one-track sound programs. The magnetic tape is applied like "1", wound on special cores. Full core contains 500 meters of tape. Recording or playback times respectively; 10, 21 and 42 minutes. The tape recorder uses separate recording and playback amplifiers, which allows you to control the quality of phonograms directly during recording.

The working range of the recorded or reproducible frequencies at higher speeds is 40 ... 12000 Hz at medium speed - 50 ... 7000 Hz and at lower speed - 60 ... 4000 Hz. The amplifier of the tape recorder has a rated output power of 3 watts, maximum 7 watts. The nonlinear distortion factor of the recording path is 3%, the reproduction path at a nominal output power of 5%. The tape drive mechanism uses 3 asynchronous capacitor electric motors. Power tape is supplied from the mains. Power consumption when recording 250 watts, while playing 280 watts. The case of the tape recorder is made of wood with imitation of valuable species, polished.
