The spotlight is on

Small, robust and splash proofed against sweat ingress when worn close the body the miniTX has been designed to meet the demands of modern studio and sound sound recording. Measuring only 82mm high by 48mm wide by 16.5mm thin, it weighs a tiny 90gms including batteries. Comfortable and easily hidden, even in tight costumes, it is as much a favourite of the artist’s and costumier’s as the professional sound recordist.

Stay in control

It’s not just the size and weight that makes this transmitter popular with artists and costumiers. The miniTX can be switched On/Off, frequencies checked and changed, and battery status monitored using the SwitchIR. It can also be switched On/Off through clothing with the Control-X, which removes the need to adjust costumes during filming.

Up to 24MHz switchable bandwidth

The miniTX has up to 32 pre-programmed frequencies, with a switching bandwidth of up to 24MHz (the equivalent of 3 European or 4 U.S. TV channels).

Powered by 2xAAA batteries

The miniTX can run for up to 5 hours on 2xAAA 1.5v batteries or up to 10 hours with Lithium batteries.
