The Cab-Link is a completely passive audio merger that allows you to connect a single amp head with two speaker cabinets. It has a maximum power rating of 400 Watts, and can be operated in series or parallel configuration depending on the impedance ratings of the amplifier and cabinets. 14 gauge steel construction and high quality components ensure the Cab-Link will last for years, and a ¼” line output with variable level control provides additional flexibility for signal routing.
