The Audio Ltd. miniTX Transmitter (542 to 572MHz) and CX2/S Receiver Set (512 to 572MHz) includes two transmitters, a receiver for Sony Slot equipped cameras, a 15-pin D-Sub connector, two VT500 omni-directional lavalier microphones, wire clips, neoprene miniTX pouch, SwitchiR, antennas and a standard 24" (609.6mm) auxiliary output cable. 

The miniTX Ultra-Mini transmitter is a compact and lightweight professional UHF transmitter that can be easily hidden in a tiny pouch. Devoid of any switches or menu screens, this slim transmitter can be easily mounted on professionals such as artists, costumiers, and sound recordists. This transmitter does not feature switches or menu screens. 

The IR menu can be navigated by pointing the included SwitchiR key-fob controller on the top of the miniTX Transmitter to adjust all its parameters. The microphone input via a LEMO 3-pin locking connector provides powering that is compatible with most electret lavalier microphones. Powered by 2 AAA-type batteries (sold separately), the transmitter provides up to 5 to 7 hours of transmission and can be turned off simply by removing the batteries. 

The CX2/S 2-Ch Slot-Mount Camera Receiver for Sony Camera is a professional UHF receiver for field production sound. The receiver offers excellent RF range and up to 80MHz switching bandwidth. A stylish design with front-end digitally controlled tracking filters delivers True Diversity performance. 

The CX2/S receiver is compatible with Sony cameras with integrated receiver slots. The intuitive menu uses a blue Organic Light Emitting Diode (OLED) display that is clear and yet consumes very little power. All parameters can be set by three buttons on the top of each unit. 

The receiver channel 1 output and external DC are via the 15-pin D-Sub connector on the bottom of the unit. The Aux channel 1 and 2 outputs via the Binder 7-pin connector on top.

Note: LEMO wiring of Lavalier microphones is same as for Sennheiser.
The CX2/S cannot be powered through the Binder 7-pin connector.
