Product Description
HCR-30D is a wireless microphone system specially designed for professional cameras. At the same time, the intelligent channel diversity receiver can be divided into single channel true diversity and dual channels antenna diversity switching. Mainly used in professional video cameras, with wireless handheld microphones or wireless bodypacks, the camera can avoid the ties of the microphone signal line during recording, make the distance between the audio and video more closely combined, achieve the recording effect of the original sound reproduction, and ensure the camera's sound quality. Motorized operation, more flexible, convenient and safe to use.
Functional Features
Multi-function Output Module
It is equipped with three kinds of output modules, "D-Sub 15P " and " D-Sub 25P" and MinI XLR , which are easy to remove and replace the fixed bracket, for easy installation on different video recorders.
True Diversity Reception
Ultra-wideband UHF 522MHz~936MHz, true diversity reception.
[AFS] Automatic Frequency Search
It has the function of [AFS] to automatically search for the cleanest and freest frequency in the actual environment.
PLL Phase Locked Oscillation Circuit
Stable PLL phase-locked oscillator circuit,combined with the "noise detection" mute control function, can effectively block the noise and radio frequency interference in the working environment.
DSP Audio Expansion Algorithm
The unique DSP audio expansion algorithm is adopted to minimize the noise caused by wireless transmission and restore the best sound. The audio output of the receiver can be set to multiple modes (mixing, mixing 1, mixing 2, audio separation).
[IR]Infrared Automatic Frequency Adjustment
With [IR] infrared automatic frequency matching function.
