Feature
- * Adopt a microphone with super cardioid polar pattern, which supports 48Khz sampling rate to ensure high-quality sound;
- * Based on 3-layer network transmission technology, compatible with standard network protocols, support 48Khz/16-bit across-network audio transmission;
- * Support paging broadcast, support scheduling through system management software, support broadcasting calling to designated zones;
- * Support full duplex two-way intercom function to realize hands-free call;
- * Built-in echo cancellation function, and network echo suppression;
- * Adopt independently developed data transmission technology, support extremely low end-to-end transmission delay, and realize zero-delay experience;
- * Built-in 2W monitoring speaker, with clear and powerful sound.
- * Support the power supply mode of 12V DC power adapter;
- * Support remote firmware upgrades through the LAN without disassembling the machine, which reduces the work intensity of maintenance personnel.
