This is the Artsound SVC6, a simple multiroom controller designed to deliver stereo sound into up to six zones from a single amplifier. It's designed for residential or commercial installations, and is yours for just £150 from UK distributor Unique Solutions Distribution.
The SVC6 has separate volume and on/off buttons for each zone, and is designed for use with speakers of 4-16ohm impedance. It's designed to prevent the amplifier feeding it from being presented with a potentially damaging low impedance, and can be used with amps of up to 180W per channel.
A smaller version, the four-zone SVC4, is available for around £120, and as you may have gathered from the picture, the units come in black or silver-grey.
