MIPRO's ACT-20T - a compact, miniature transmitter - becomes a complete freedom of mobility when connected with a headworn microphone with no bodypack and no cable. This true wireless solution offers a hands-free operation without cable entanglement and poor connection problems.

The ACT-20T utilizes PLL synthesized technology for increased RF stability and packed in a lightweight, miniature housing so the transmitter can rest comfortably and secure behind the head of the performer for an unobtrusive view.

Featuring built-in rechargeable lithium battery with a quick charger for extended battery hours and patented ACT sync enables fast and easy transmitter setup from any MIPRO receivers. ACT-20T can be connected to a MU-23d or MU-210d headworn microphone with detachable (screw-lock type) microphone boom for a truly wireless audio transmission solution.

ACT-20T is easy to use and ideal for education, theater, aerobics/fitness and houses of worship applications.
