VA-6504 BD1 Intercom Panel PA System


  • * Embedded rectangular design, simple appearance, exquisite craft, and durable structure.
  • * Based on 3-layer network transmission technology, compatible with standard network protocols, support 48Khz/16-bit across-network audio transmission;
  • * Support one-key help, support calling the intercom microphone of the duty room to realize quick connection, with convenient operation.
  • * Adopt a microphone with super cardioid polar pattern, which supports 48Khz sampling rate to ensure high-quality sound;
  • * Support hands-free calls and receiving broadcasts.
  • * Two installation methods: embedded installation and surface-mounted installation.
  • * Support full duplex two-way intercom function; adopt built-in network echo cancellation modules; realize two-way intercom between IP terminals, extremely low end-to-end transmission delay(5ms), and complete network echo howling suppression.
