Spread your sounds around your home or business with this Monoprice 2-Channel A/B Speaker Selector with Volume Control! This speaker selector allows you to connect two stereo source and two stereo destination zones. Each destination zone can be independently enabled or disabled and individually connected to either source. Each destination zone has its own volume control, so you won't have to suffer to excessive volume in one room or insufficient volume in the other. This selector switch supports up to 100 watts per channel with a frequency range of 20 Hz to 20 KHz. The speaker wire connectors on the back accept bare wire up to 14AWG. The selector switch maintains a constant 8 ohm load to the amplifier(s) even when both zones are assigned to the same source. Note: It is recommended to use only 8 ohm speakers with this selector and to connect no more than one pair of speakers to each zone.
