BG-24

Digital Wireless Microphone Receiver

Product Description

BG-24 is a newly launched 2.4G digital wireless microphone system from the Relacart MIPASSPORT series. The appearance is simple and elegant, made of strong and durable alloy; the high-brightness OLED display can clearly display the working status of the device. Optional handheld microphone wireless charging base makes charging management more convenient; it uses ISM's global unrestricted 2.4GH frequency band for transmission and can be used in any area. Relacart independently develops digital audio algorithms, allowing the host to have ultra-low latency transmission; it is fully suitable for small and medium-sized performances, business negotiation venues, conference rooms, schools, home entertainment and other occasions.


Functional Features

Independently developed low-latency compression algorithm

Relacart independently develops digital audio algorithm with compression and decompression latency less than 3 ms, significantly ahead of other 2.4G digital wireless microphones on the market and provides an excellent solution for the overall digital audio system. Additionally, the frequency occupied bandwidth is less than 1MHz, greatly reducing the external and intermodulation interference.

Stable wireless transmission

Relacart's innovative wireless audio system circuit provides it with a stable wireless transmission. • It has antenna diversity reception mode to ensure safe wireless signal reception. • Frequency diversity provides backup frequencies and automatic hopping functions, allowing it to flexibly avoid complex wireless frequency interference. • Time diversity technology works by transmitting the same signal at different times. The receiver can receive multiple independently fading copies

2.4G unlimited frequency band

Adopting the globally unrestricted 2.4G transmission frequency band, it can be used freely in any region without frequency restrictions. The effective transmission distance is up to 50 meters in open environments.

Optional dual-bay chargers

Optional contact-type dual bay changer, simply place the microphone into it for charging. Utilizing rechargeable NiMH batteries, it offers a longer lifespan compared to alkaline batteries, ensuring enhanced safety, durability, and environmental friendliness. This convenient charging method is suitable for various scenarios requiring frequent charging.

High fidelity sound reproduction

The BG-24 digital wireless microphone system provides users with an extremely flat frequency response curve. It has a frequency response range of 20-20kHz and a distortion of <0.1%, giving the most fidelity sound for speech reproduction.
