Radio and electrical constructors, sets.Audio AmplifiersThe radio designer "Start 7239" (Loudspeaker protection device) has been producing the Kamenets-Podolsk plant "Electropribor" since 1988. The radio designer allows you to assemble an AC protection device designed to turn off the power of the PA with bipolar power when a constant voltage appears at the output of one amplifier channel due to the failure of the output transistors, blocks the power supply in the absence of voltage of one of the polarities, in addition, removes clicks in the AC at the moment of switching on nutrition. The device is powered by the power amplifier power supply. Supply voltage ± 25 ... 30 V. Dimensions of the device - 167x92x45 mm. Its weight is 200 grams.
