Helpful to know:
Wireless microphones are not Bluetooth microphones. The microphones communicate wirelessly with the receiver, while the receiver connects by cable to the sound system.
The MI-400 Pro is designed to make two-microphone operation easier while supporting stable wireless use and straightforward receiver maintenance.
The package includes two metallic wireless handheld microphones, allowing two singers, hosts, or presenters to use the system at the same time.

This allows both microphones to be used simultaneously for duets, co-hosting, interviews, presentations, and group entertainment.
The MI-400 Pro uses UHF wireless transmission in the 800 MHz class according to the supplied product information.
UHF operation can provide stable wireless performance, but the exact supported frequency range and permitted channels should be confirmed for the current unit and operating location.
The receiver uses PLL-based automatic channel targeting to simplify channel selection.
This function is designed to help the system locate and maintain suitable operating channels while reducing setup difficulty.
The MI-400 Pro has a listed operating range of up to 100 feet from the receiver under suitable conditions.
Actual range may be reduced by walls, people, nearby wireless devices, antenna placement, receiver location, and line of sight.
The handheld microphones have a listed operating time of approximately 8 hours when powered by suitable AA batteries.
Actual battery life varies with battery quality, microphone use, storage conditions, and transmitter settings.
Each receiver channel uses its own replaceable module that can slide out for service.
This modular design can make maintenance easier and may allow one channel module to be repaired or replaced without replacing the complete receiver.
Each microphone channel has its own dedicated receiver module.
Separating the two channels supports independent operation and helps simplify troubleshooting when one channel requires service.
The package includes one 1/4-inch to 1/4-inch microphone connection cable.
This cable can be used with compatible karaoke amplifiers, mixers, or sound systems that provide the appropriate input.
