Tape recorder `` Dnipro-11 '' (Dnipro-11).
Tape recorders and radio tape recorders.The network reel-to-reel tape recorder "Dnipro-11" has been producing the Kiev Radio Plant since 1960. The tape recorder uses a two-track type 2 and CH tape recording system. The tape recorder has tape speeds of 19.05 and 9.53 cm / sec. Recording time 2x30 and 2x60 minutes when using reels No. 18, with a capacity of 350 m. Tape. LPM allows the use of coils No. 22 with a capacity of 500 m. Tape. The frequency range is 40 ... 12000 Hz at a higher speed, 100 ... 6000 Hz at a lower one. There are tone controls. Knock coefficient 0.5 and 0.9%. The sensitivity of the microphone recording amplifier is 0.5 mV, the pickup is 200 mV, and the linear one is 10 mV. Maximum output power 5 W. LPM control is keyboard. Power consumption 160 watts. Dimensions 55x33x33 cm.Weight 24 kg. The tape recorder differs from previous models in an indirect drive. The asynchronous engine DVA-U4 was replaced by the synchronous engine DVA-U1. Second belt speed introduced. The erasure and bias generator, as well as the LF amplifier, are made according to a push-pull scheme. The tape recorder allows you to make trick recordings. From the Dnepr-11 tape recorder, the following models became known as Dnipro with the addition of development numbers.
