ZG-3-01 Hands-Free Audio Module

  • Support for two acoustic signal sources (inputs X1 and X2, 0.7 V)
  • Wide range of output power (volume) adjustment
  • Transparent transmission of PTT signals
  • Frequency response: 400 Hz – 4 kHz
  • Compatible with various headsets and telephone systems from different manufacturers
  • Compliance with military standards for environmental resistance, mechanical durability, and electromagnetic compatibility 
G-3-01 functions as a speakerphone unit installed between a telephone handset and the operator’s headset. The device supports two independent acoustic signal sources with a standard input level of 0.7 V. This allows the operator to monitor or switch between different audio channels depending on operational requirements. 
 
A wide range of output power (volume) adjustment enables the audio level to be adapted to working conditions, particularly in environments with elevated noise levels. Transparent transmission of PTT signals ensures full system compatibility, regardless of the manufacturer of the interconnected devices. 
 
The ZG-3-01 is designed for continuous operation in demanding environments. It complies with military standards for mechanical and climatic resistance (NO-06-A101 to NO-06-A108) as well as electromagnetic compatibility (NO-06-A200). Its robust construction and standard audio and power connectors enable easy integration with both legacy and modern communication systems.
