AKG The WMS 40 mini2 vocal and instrument systems both have top-notch sound quality and incredibly easy operation (plug and play; turn on and you're on) at a price/performance that's completely out of competition.
AKG The SR 40 mini receiver has three status LED lights; one for on/off, one for signal reception OK, and finally one for signal strength/peak/overload. The volume control controls the output level at ¼? jack on the rear.
AKG The PT 40 mini beltpack (in the instrument system) is probably the smallest and lightest yet. A mini XLR connector takes both instrument cable, but can also be used with AKG headset and clip-on microphones (optional). The compact pocket transmitter has mini-XLR in, and as well as instrument cable included.
It's also worth mentioning that the transmitters have 30 hours of life on a single AA battery!
