Functional characteristics
1. Metal panel design, overall high-grade solemn, in line with modern aesthetic standards
2. The unit is a passive device, powered by the system host, and the input voltage is 24V, which belongs to the safe range
3.8 The unit of core wire interface adopts T-type 8-core connection, and the wire adopts all-wire aluminum foil and waterline shielding, which greatly reduces the interference of strong electromagnetic wave on the wire
4. The unit of the network cable interface adopts the Class 6 network cable, which is connected by the "handle" cable, with two RJ45 ports and a jacket to prevent loosening
5. Professional high-fidelity capacitor core, sensitive pickup, clear speech, bandwidth up to 20Hz~20KHz
6. The anti-interference circuit design can prevent the interference of mobile phones and other electronic products
7. The microphone head is equipped with a two-color speaking light ring, which is steady red when the unit speaks and steady green when the unit applies to speak
8. Sensitive touch switch, if the standby is not on time, the pattern will light up green, and the pattern will light up red after pressing
9.2.4 inch high brightness IPS TFT display, the display content is clear, can display unit parameters, date and time, speaking volume, monitoring volume, etc., clearly understand the current use
10.★ Microphone with speech timing function
