HCR-30D is an ultra-small wireless microphone system designed for professional camera
positioning. At the same time, the intelligent channel diversity receiver can be divided into
single channel true diversity and dual channels antenna diversity switching. It is mainly used in
professional Video camera, with wireless handheld microphone or wireless bodypack, so that
the camera is free from the interference of microphone signal line during recording, so that the
distance and positioning of video and sound are more closely combined, so as to achieve the
recording effect of original sound reproduction, and ensure the mobile operation of the camera,
more flexible, convenient and safe use.

Key Features:
· Has a sturdy and water-resistant aluminum alloy housing to meet professional quality
requirements. The new technology OLED display can display the transmitter battery, radio
frequency and audio working status at the same time.
· Equipped with super quiet electronic touch switch, which can avoid the mechanical sound
amplification of the switch.
· Equipped with “Panasonic” and “SONY” two kinds of easy to disassemble and replace the
fixed bracket output module, easy to install in different video cameras.
· Separate SMA soft antenna and antenna connector with adjustable Angle of 1/4 wavelength
are adopted.
· Super wide frequency selection UHF 521.25MHz~ 936.85MHz, true diversity reception.

(Transmitter optional product)
(SONY adapter) (Panasonic adapter)
(Receiver)
· It has the function of [AFS] to automatically search for the cleanest and non-interference
frequency in the actual environment, enter the setup menu and select AFS function, the
receiver will auto-scan and lock the working interference-free frequency.
· With [IR] infrared automatic frequency matching function, press the [SYNC] button, the
transmitter can automatically and accurately lock the working frequency of the receiver.
· Stable PLL phase-locked oscillation circuit, with “noise detection”mute control function,
can effectively block noise RF interference in the working environment.
· The unique DSP audio expansion algorithm of Relacart is adopted to minimize the noise
caused by the wireless transmission process and restore the best sound. The audio
output of the receiver can be set to multiple mode output (two mixing, mixing 1, mixing 2,
audio separation)
· The design of hand-held microphone is simple, flexible and light, showing the soft grip
feeling of humanization.
· Precision low-consumption circuit design, so that the battery life is twice as long as the
ordinary microphone.
· The hardware circuit of the whole system is controlled by a microcomputer. Advanced
computer technology is used to calculate the frequency without interference with each
other, which makes the performance of the whole system more stable and less prone to
frequency deviation and frequency break.

The appearance of the OLED main window will change depending on the selected diversity mode:
Dual channel mode: Set the receive separation mode to dual channel mode, two audio channels
will be displayed.
Single-channel true Diversity mode: Setting the receive separation mode to single-channel true
diversity mode will display a single audio channel.
The main window displays information about antenna phase, audio level, frequency group
channel, frequency, volume level, EQ, and battery status for the receiver and associated
transmitter.
Press the “ ” menu/select button to access the menu and interface to set the receiver and search
for clear channels.
Note: When single-channel true diversity mode is selected, two receivers are combined to receive
the same transmitter, so the main window displays a single audio channel.

Various accessories are available to enable various installation options. For maximum
operating range, the antenna should be placed vertically above the camera and other equipment.
The SMA soft antenna is connected so the whip can be vertically oriented.
Do not install the receiver here, so that the antenna is close to other equipment or horizontal
position.
A cross screw holds the receiver to the adapter.
Countersunk hex screws secure the adapter to the camera body.
Note: If you are having trouble inserting the receiver into the
camera slot, try attaching the black adapter to the camera first
before inserting the receiver.
Install the rear panel adapter
The installation of the rear panel output adapter is the same for all models.
The panels are held in place by
two cross screws on either side
of the housing.
The connection between the panel and the main
circuit board is made through miniature companion
connectors.
Align the matching connectors
and slide the panel directly into
the housing until the screw hole
is aligned with the housing.

The receiver is installed so
that the antenna extends into
clear air and is vertically
oriented to provide a circular,
horizontal coverage pattern.
