Wireless system Mipro ACT 707D HH BP

Radio system Mipro ACT 707D

The dual radio system can be equipped with:

Two handheld condenser microphones

One handheld microphone and one belt transmitter.

Two belt transmitters

Handheld radio microphone with a condenser capsule and supercardioid polar pattern, possessing impeccable reproduction accuracy, wide dynamic range, fast transient response, minimal feedback, and precise sound image, fully embodies this principle.

Features:

Metal housing (handheld microphone), plastic housing (belt transmitter).
Power switch on the body under a protective cover
LCD screen displays group, channel, battery level, debug code
Unique MIPRO style embodied in the refined ergonomic design of the radio microphone
Supercardioid condenser capsule is ideal for vocals, providing high intelligibility, wide frequency range, deep dynamic range, fast response, minimal feedback, clarity, and accuracy of sound image, forming the best sound quality in the modern digital age
Patented modular capsule design provides extremely low body noise levels, with few competitors
Unique dual microphone grid design made of steel eliminates pop noise and wind noise while not degrading high-frequency transmission and polar pattern characteristics
Optional interchangeable microphone capsules – condenser or dynamic to suit the performer’s individual taste
For the first time in the world, the ACT function (automatic channel positioning) is implemented, allowing instant and automatic transfer of radio channel parameters from the receiver to the transmitter
High fidelity modulator circuit can handle high input levels with minimal distortion coefficients
Improved effective low power consumption circuit ensures uninterrupted operation of the radio microphone from one set of batteries 2-3 times longer than competitors
Professional quality and shock resistance

High sound pressure levels without distortion

The unique high-precision high fidelity modulation circuit ACT-7H freely handles sound pressure levels (SPL) up to 142 dB across the entire spectrum of sound frequencies from 50 Hz to 15 kHz (+1~-3 dB). At the same time, the coefficient of nonlinear distortion (THD) does not exceed 0.9%. Moreover, since the sensitivity of the modulator circuit is set in exact accordance with the sensitivity of the capsule, there is no need to adjust the microphone level to achieve optimal loudness and dynamic range. This technology provides clear and powerful reproduction of high frequencies, eliminating the need to reduce volume to avoid distortion. These capabilities are not easily found among the offerings of other manufacturers.

Innovative ACT function replacing traditional manual tuning
ACT-7H uses UHF carrier frequency synthesis based on phase-locked loop (PLL) principles. The carrier frequency of a conventional radio microphone is set manually. This tuning method is further complicated by the potential for error. To avoid such problems, MIPRO developed, patented, and first used the ACT function (automatic channel positioning) in its radio systems instead of conventional manual tuning. By pressing just one SCAN button on the receiver, these convenient and user-friendly radio systems automatically and quickly tune the operating frequency of the radio channel. Such instant and precise tuning helps avoid mistakes that are often made when manually tuning radio systems.

High-efficiency circuitry and excellent electronic execution

Inside the ACT-7H operates a high-efficiency circuit with low interference, economical power consumption, which provides an impressive operating time of 18 hours from 2 AA batteries.
