Tested and working. Allows one amplifier or receiver to power and independently control volume for up to four pairs of speakers. Features selectable impedance matching to help protect the connected amplifier when multiple speaker pairs are in use.
Includes all removable speaker wire connectors and the spare room/speaker labels.
Features:
• Independent volume control for each of four zones
• Selectable impedance matching
• Supports up to four pairs of speakers
• Handles up to 100 watts per channel
• Heavy-duty metal chassis
Good used condition overall. There is a small dent/scratch on the left edge of the chassis, as shown in the photos. Otherwise, the unit presents well for its age.
Great for whole-home audio, in-ceiling speakers, outdoor speakers, or other multi-room stereo setups.
