2.4GHz Digital Wireless Frequency

Like the RØDE Wireless Go or the Sennheiser XSW-D series, the Comica BoomX-D series uses the 2.4 GHz wireless bandwidth, which means they work globally. The wireless digital transmission ensures stability with automatic adaptive frequency hopping technology. This means that it will find the best frequency to operate on to minimise interruption and interference. As it is optimised for shorter range operation in dense WI-FI environments, reducing signal drops and intrusion, for exceptional clarity and reliability.

Dual Transmitters 

Transmit audio of up to two transmitters in just the one receiver in real time, this can be especially useful for interviews or broadcasts where you need to record audio for more than one person, giving an easy solution under one receiver.

Easy Status Monitoring

The clear bright TFT LCD display will show the battery status of the transmitter and receiver, and audio dynamic monitoring to show the audio level in real time on the screen. As well as the pairing status and signal strength to monitor and reduce the chance of broken, quite or cut audio.

Internal and External Microphone 

The internal and external microphones help to choose the right kind of audio recording based on your needs. Whether you would like to record single audio or multiple audios, for example a room or group, it can be especially useful to have this function with the input modes to get the best mode for you.

Switchable Output Modes (mono/stereo)

To record a single or multiple audio at any one time, the switchable modes can easily be controlled and offers great flexibility when recording audio.

Real-time Audio Monitor 

Listen to your audio in real time through the 3.5mm connector. Connect your headphones to the BoomX-D system and listing to the audio recording. This can help to ensure you are recording a clear audio without interruption and make sure the microphones are working correctly without malfunction or signal problems.

Broadcasting Quality Audio

The BoomX-D system will record rich details and deliver a high-quality natural sound. With a higher sample rate at 48KHz it guarantees high-definition recreation of the original audio. As well as the 16-Bit depth which increases audio fidelity and provides more natural sound output

RF Technology, Auto Freq. Adjustment, Stable Transmission 

Perfect for using at shorter ranges in dense WI-FI environments, reducing signal drops and intrusion, for exceptional clarity and reliability. This will find the most suitable frequency and automatically adjust, ensuring a stable transmission.

Low Latency

In order to ensure clear and natural sound, that is fluent and smooth the BoomX has a very low latency of less than 20ms, this is especially useful when matching sound to video to make sure it seems natural, providing professional results.

Multi-functional Belt Clip

The compact belt clip means that you can attach this easily to your trousers or belt to ensure it is secure and out of view. This can be important to the quality of recording and not break immersion. It also means that the BoomX system is easily portable and can be forgotten about when recording.
