The mini TX Transmitter
The
miniTX wireless microphone transmitter is designed for modern stage,
studio, and location sound recording. Comfortable and easily hidden even
in tight costumes, it is a favorite of the artists and costumers as well
as the professional sound recordist.
The miniTX is small, robust
and moisture resistant against sweat when worn close the body. Measuring
82mm high by 48mm wide by 16.5mm deep (3 ¼ x 1 7/8 x 5/8 inches), it
weighs only 90 grams (3.2oz) -- including batteries.
It can be switched On/Off, frequencies checked and changed, microphone
gain adjusted and battery status monitored with the included SwitchIR
infrared controller or with a Palm Pilot using free software. It can
also be switched On/Off through clothing with the Control-X. The miniTX
has up to 32 pre-programmed frequencies, with a switching bandwidth of
up to 24MHz (the equivalent of 4 US TV channels). The miniTX runs for up
to 5 hours on 2xAAA 1.5v alkaline batteries or up to 10 hours with
lithium batteries.
All Audio Ltd. transmitters are designed to work with
the microphone of your choice. Our technical department is available to
