Subscriber loudspeaker "Angara".

Subscriber loudspeakers.DomesticSince 1951, the subscriber loudspeaker "Angara" has been producing the Lviv Telegraph Equipment Plant. The Angara subscriber loudspeaker (type 0.2GD-IV-2) completely repeats the design of the Tula AG in 1949, with the exception of the calculated voltage of the radio transmission network, here it is 30 volts, while the base model was also produced at 15 and 30 volts. The main difference between Angara and other subscriber receivers of this type, as in AG Tula, is the loudspeaker itself, all its mechanical and electrical parts are inside the diffuser. Angara reproduces an audio frequency band from 150 to 4500 Hz with an input of 200 mW of electrical power and develops a sound pressure of 3 bar. Maximum distortion rate 7%. AG weight 1.1 kg.
