Product Detail

Detailed

Comply with IEC60914, GBT15381-94 international standards
Patented appearance design, overall high-grade and solemn, in line with modern aesthetic standards
The unit is a passive device, powered by the system host, the input voltage is 24V, which is a safe range.
8-core line interface unit using T-type 8-core line, the wire using the whole line of aluminium foil, waterline shielding, greatly reducing the interference of strong electromagnetic waves on the wire
Network cable interface unit using ultra-six category network cable, ‘hand in hand’ line connection mode
Professional high-fidelity capacitor microphone core, sensitive pickup, clear voice, bandwidth up to 20Hz ~ 20KHz
★ The use of spiral aviation plug carillon, more effective in preventing poor contact and caused by blasting sound.
Built-in high-fidelity/anti-mobile phone signal interference capacitive head.
★Anti-interference circuit design, can prevent mobile phones and other electronic products interference
★Light ring is always on red when the unit is speaking.
★Microphone switch without mechanical key sound, long life.
★Sensitive touch switch, press the pattern is always bright light red
★ microphone unit interface, using a closed-loop Ethernet link mode, but also ‘hand in hand’ connection, support for hot-swappable for easy installation and maintenance, optional 8-core line interface / DATA network interface
★The chairman unit is not limited by the number of speakers.
★Optional, 8-core cable interface / network interface
