First up we look at the new Wireless systems from AT - the System 8 is a VHF fixed frequency wireless system for handeld mic at $99.
System 9 has 4-channels to choose from for less chance of interference
System 10 - is a 2.4gHz wireless system - which handles one or two channel operation and offers a true diversity (it finds the best channel to work on). Comes in two flavours - single channel and dual channel.
ATH M50WH Studio headphones get a new colour - well white actually. These headphones are considered to be great audio quality at around $170
Also they have a limited edition line of 50th Anniversary products with special design tweaks, fancy cases and blue/grey colour schemes. When they're gone they're gone...
