Lightweight Noise-Free Headset GBSH-1A for Reliable Communication

Lightweight headset GBSh-1A with "ear hook" fastening is designed for operation as part of communication equipment at ambient air temperature from +5 ºC to +40 ºC and atmospheric pressure from 84 to 107 kPa (from 630 to 800 mm Hg). Perfect for conditions where you need to quickly remove/wear the headset or at the same time, while working with communication, monitor external sounds. The GBSh-1A modification is produced with a four-pin connector (at the customer's request, headsets can be produced with another type of connector or with free pins). The headsets provide the possibility of adjusting the output voltage within the range of 400-1600 mV during operation by means of a variable resistor installed on the amplifier board. Transparent sound guide with a medium-sized ear piece.
