AKG WMS40 Mini Instrumental Set ISM3
The SR 40 Mini receiver provides three status LEDs indicating ON/OFF status, received signal strength (RF OK), and audio clipping (AF CLIP). The VOLUME control sets the level at the ¼" output jack. The PT 40 Mini bodypack is probably the smallest and lightest transmitter in its class. A reliable mini XLR output allows you to connect every compatible AKG miniature microphone. Battery life of the transmitter is the same legendary "30 hours off a single AA battery" as for the WMS 40 models, reducing the need to replace batteries and thus saving real money in the long run. The system includes a MKG L instrument cable, a universal power supply with US/UK/EU adapter, and one AA size dry battery.
The ISM3 sets operate at 864.850 MHz.
