Now you can hear your HI-FI in another room with a second pair of speakers using this simple and neat controller. Designed to switch two pairs of loudspeakers, the BT12’s "1+2" mode allows you to hear both pairs of speakers or separately. Ideal for the kitchen, bedroom or study. This high quality in-wall volume control is easy to install and you can conveniently locate it anywhere for locally controlling remote-sited speakers. Suitable for all standard 2-gang electrical boxes that are 47mm deep. The use of MK or other good quality metal boxes is recomended. Rubber grommets must be used in the ’knock-out’ holes to prevent speaker cable chafing. • Listen to either pair of speakers separately or together. • Strong connection by spring terminals. • Accepts cable up to 79 strand (2.5mm). • Suitable for speakers from 4 ohms to 16 ohms. • 150 watts RMS per channel rating.
