Mipro ACT-700H/MU-90
Aesthetically designed in special fog black color metal housing features the most comfortable handheld size and presents ultra-low handling noise and a luxurious professional appearance.
The unique metal grille of the microphone capsule module can be divided into the upper grille and the lower grille. The upper grille can be detached for cleaning; the lower grille is connected with the housing by an external thread. The robust metal grille protects the capsule against impact, rolling and pop noise, and ensures clarity of sound.
The patented power switch module integrates mute, set buttons, LCD and power switch lock hook for convenience to operate and prevents the power switch from accidental operation.
In addition to the power switch and the mute button, functions such as input sensitivity, low frequency reduction, volume limit, power output and mute mode are also programmable.
5 switchable gain levels with input sensitivity preset to equal the sensitivity of the microphone capsule at 0 dB.
The world’s first ACT™ function provides precise and rapid frequency sync to the receiver.
The patented battery compartment can be inserted with two AA-type batteries or one rechargeable Li-ion battery, charging via USB Type-C with the foolproof and safe charging circuit. The second-generation ACT-700H features charging contacts and can also be placed on an optional single-slot or dual-slot charging station for charging.
A color-coded channel identification ring is put on the end of the housing. A high efficiency wideband transmitting antenna and USB Type-C charging socket built in a patented antenna cover on the bottom of the housing.
