BBS premium receivers adopt a professional AC constant-power design for stable 24/7 commercial operation, making them suitable for KTV rooms, stages, banquet halls, and other commercial environments.

The handheld microphones do not require customized lithium batteries. They support globally available 1.2V–1.5V standard AA dry batteries, providing worldwide compatibility, low maintenance costs, and convenient daily operation.

Batteries are not included unless otherwise stated in the product package information.

BBS flagship wireless microphone systems use commercial UHF frequency bands designed to reduce interference from Wi-Fi, Bluetooth, 5G, and other common wireless signals.

The AX-4000 PLUS is equipped with 200 professional channels and an automatic infrared frequency-pairing system, providing more available frequencies and greater flexibility than ordinary 2.4 GHz microphone systems.

Multiple systems can operate together in bars, multi-room KTV venues, banquet halls, and other high-density commercial environments when the frequencies are properly configured.

The stated transmission distances are based on professional testing in open and unobstructed environments.

BBS premium microphone systems use enhanced signal-transmission technology designed for environments containing walls, crowds, metal structures, and other obstacles.

Actual operating distance may vary depending on the installation, interference level, venue structure, antenna position, and surrounding equipment. Correct system placement and frequency configuration are recommended for the most stable performance.

This is not a malfunction. It is an intelligent commercial feature available on BBS premium microphone systems.

The AX-4000 PLUS, EX-2, and CS-6 include an intelligent sleep system that detects when a microphone is not being used. The system can turn off the display, reduce power consumption, and mute idle background noise.

This helps extend battery life and maintain a cleaner sound environment. The microphone automatically wakes up when it is picked up again.

The three BBS flagship models use professional noise-reduction technology and intelligent anti-howling processing designed for commercial audio environments.

The systems help reduce wind noise, ambient noise, electrical static, and high-frequency feedback during vocal use.

They are suitable for enclosed KTV rooms, conference spaces, banquet venues, and outdoor performance stages where clear and natural vocal reproduction is required.

The complete BBS one-receiver, two-microphone system is a professional vocal signal source designed for KTV rooms, wedding stages, conferences, live performances, and commercial events.

It performs five main functions: vocal capture, intelligent noise reduction, professional frequency locking, vocal optimization, and stable wireless signal transmission.

The system does not include a built-in loudspeaker. It must be connected to a compatible mixer, amplifier, active speaker, or other audio system before sound can be produced.

BBS premium microphones do not use artificial electronic pitch correction or software-style auto-tune effects.

The systems use hardware-level vocal optimization and commercial frequency-response tuning designed to enrich vocal midrange, smooth harsh treble, reduce distortion, and soften excessive sibilance.

The purpose is to improve clarity, fullness, and listening comfort while preserving the natural tone and expression of the original voice.
