Relacart HCR-30D Dual-channel ENG wireless microphone receiver

Model: RELA-HCR-30D
Part Number: HCR-30D
Brand: Relacart

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.

Product Features

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).

True Diversity Reception

Ultra-wideband UHF 522MHz~936MHz, true diversity reception.

Electronic Touch Switch

Equipped with ultra-quiet electronic touch switch, which can avoid the mechanical sound amplification of the switch.

Multi-function Output Module

It is equipped with two kinds of output modules, "Panasonic" and "Sony", which are easy to remove and replace the fixed bracket, for easy installation on different video recorders.

[AFS] Automatic Frequency Search

It has the function of [AFS] to automatically search for the cleanest and freest frequency in the actual environment.

[IR]Infrared Automatic Frequency Adjustment

With [IR] infrared automatic frequency matching function.
