Universal tape recorder "MAG-2A" was produced from III-q 1948. VNIIZ, together with the experimental plant of the All-Union Radio Committee, based on the tape recorder '' MAG-2 '' developed the tape recorder '' MAG-2A '', in which, by refusing to rewind the film, the LSM was simplified. The tape recorder '' MAG-2A '' is intended for recording phonograms onto a standard ferromagnetic tape, mainly speech programs and playing them through a remote speaker. The signal can be simultaneously fed to a line for later reproduction via the broadcast path. The tape recorder allows you to record from a dynamic microphone, line, radio and adapter. The device is adapted for work in stationary and on-site conditions. Power supply through a separate power supply. The demagnetization of the magnetic tape and the bias for the recording head are carried out by high frequency current. The operating frequency band is 70 ... 7000 Hz, with deviations of ± 2.5 dB. Distortion factor (400 Hz) 4%. The noise level in relation to the nominal voltage on the LV -38 dB. The speed of the tape is 45.6 cm / sec. Recording time 12 min.
