1/6
The SL Headmic 1 is very sleek, robust and wheighs only
7g without the cable. The black and silver design almost
disappears in the environment while still offering the best
sound perfomance.
All sets also come with rechargeable accupacks with up to
15 hrs of operating time. The accupack is also USB rechargeable, the cable is in the box, the USB socket is presumably just a step away from you.
The two types of sets are either Rackmount Sets (-R version), which come with everything needed for rack mounting, or Case Sets (-C version), in a transport case – without rackmounts, if you do not want to install the receiver.
