6 These sockets should be used to connect to your loudspeaker cabinets. The Total impedance of the cabinets must not be less
than 4 Ohms. Connecting cabinets that have a lower impedance than 4 Ohms will result in the amplifier overheating. Continual
use in this manner may cause permanent damage. The best combination of cabinets to use is one RB115 and one RB410 cabinet.
