  • Introduction
  • Specification

This device is two channels UHF wireless microphone system. Compared with the traditional host, D2402 is less disturbed and more reliable in transmission by using UHF ultra-high frequency band.
With two channels, it can be connected with two microphones. The power input is DC12V, and there are channel LCD display, channel antenna, channel balanced output, mixed output and mixed balanced output in the panels. Besides, it is often applied in such occasions as exhibitions, meetings, classrooms, stores, etc.
