Portable recorder "Reporter-2" (M-30) in the autumn of 1957 produced the Gorky plant named after GI Petrovsky. The tape recorder was developed in 1956 and is intended for reporter recording of speech or speech with music and is battery operated. Recording is carried out from the microphone MD-35. A separate playback amplifier allows you to control recording directly from a magnetic tape. The recording control is carried out by the indicator or headset. The tape recorder allows for dubbing from the output to the studio tape recorders. The device is placed in a case, in the upper part of which there is a pocket for 2 spare cassettes. Carrying is done with a shoulder strap. Recording can be made without removing the tape from the case. LSM is assembled on one engine DKS-8. Recording and playback amplifiers are made on seven types of 0.6P2B and 2P1P types of radio tubes. The recorder can work in any position and on the go. With the lid closed, the coils with magnetic tape can be observed through a special window. Management of the device is carried out by one handle. Rotating motion turns on the power of the amplifiers and adjusts the recording level (and there is no playback level adjustment). The forward movement of the handle turns the LSM on and off for the working stroke. The inclusion of the recording and playback is carried out by a separate pen, located under the lid of the box. There is a lock on the inclusion of a record with an additional button. It is possible to rewind the tape. A device for deleting entries in the model is not provided.
