-
High Expandability and Flexibility
The GM-243C supports daisy-chaining of up to 120 microphones and can be used with the GMC-60 audio adapter box, ensuring stable audio transmission even in large-scale conferences. Each GM-243C unit and power supply can be installed at any position in the loop, offering great flexibility in installation and expansion. This design allows the system to easily handle both large corporate meetings and academic seminars, meeting the needs of various conference scenarios.
-
Standard Network Cable Connection
The system uses standard CAT.5e/CAT.6 network cables for audio and power connections, featuring easy installation and maintenance. The lockable RJ45 jacks prevent loose connections and unauthorized changes, ensuring system stability and security. This not only reduces installation and maintenance costs but also makes the entire system configuration more flexible, suitable for various meetings, training sessions, and presentation venues.
-
Convenient Operation and Control
The chairman unit’s priority speaking button can temporarily or permanently mute delegate microphones, with the TALK light on the gooseneck microphone and buttons indicating the speaking status. In chairman priority mode, the GM-243C's indicator lights flash red, allowing only the chairman unit to speak while muting all delegate units. Additionally, if there is no speech for 5 minutes (default), the microphone automatically turns off to save power (except in priority mode for the GM-243C). This design not only saves energy but also ensures the system's stable operation during long meetings.
-
Three-Stage Telescopic Gooseneck Design
The GM-243C features a three-stage telescopic gooseneck design. The flexible gooseneck tube can be adjusted to any suitable angle, while the telescopic hard tube can be extended to the appropriate speaking distance without moving the microphone base, ensuring the best user experience and sound quality. This design is particularly suitable for scenarios requiring frequent microphone position adjustments, such as meetings, seminars, and multifunctional halls, offering great flexibility and convenience.
