Transistor network electrophone '' Phoenix-001-stereo ''.
Electric record players and electrophones on semiconductorsDomesticSince 1975, the "Phoenix-001-stereo" transistor network electrophone has been produced by the Lviv Telegraph Equipment Plant. Designed for high-quality reproduction of recordings from stereo and monophonic phonograph records and for amplification of signals from external sources of sound programs. The EF consists of a top-class EPU OEPU-2S with electronic control, a two-channel amplifier with a six-band tone control and two loudspeakers 20AS-2, each of which contains two LF heads 10GD-30 and two HF ZGD-31. The EPU uses a GZM-105 magnetoelectric head with a diamond needle. The control of the pickup when starting with a smooth lowering onto the plate, lifting and returning to its original position at the end of playing is automatic. The EPU has a hitchhiking, disk speed adjustment and a device to compensate for the rolling force. The nominal output power of the stereo microphone amplifier is 2x15 W with a THD of 1.5%. The range of working SPs for sound pressure is 40 ... 18000 Hz. The detonation coefficient of the EPU is 0.15%, the level of interference from vibrations is -60 dB. The microphone is powered from an alternating current voltage of 127 or 220 V, power consumption is 150 W. The dimensions of the microphone are 630x420x210 mm, the speaker is 350x680x230 mm. Weight, respectively, 60 and 15 kg.
