Hi!
I've mentioned this unit before when we were discussing the B&W MM1 computer speaker system.
I didn't know at the time but the B&W A7 can also be used as a speaker set with your computer.
The A7 has a USB connection on the back along with some others which I'll get to in a moment. The purpose of the USB connection is to enable the link between the A7 and your computer.
Once the A7 is connected it appears in Windows or on a Mac as another sound device so "Go Your hardest!"
The other connections on the back of the B&W A7 are the Ethernet port for connection of the device to the Network for AirPlay use - you can of course use the old 2.4GHZ Wi-Fi if you prefer - and a line-in jack which also takes a Toslink mini connector for digital sources.
The A7 is a real party animal and should fill most rooms with decent quality sound no matter where its put.
We're talking 100 watts RMS of solid power here, 25 watts each per channel to drive the mid range and tweets and a 50 watts built-in sub-woofer to help things along - and I thought the smaller Brother in the B&W A5 had enough bass. without the woofer.
