The Koch LB-120 Load Box is a passive load box designed to safely operate tube amplifiers without the need for a connected speaker cabinet. Rated for amplifiers up to 120 watts RMS, it provides a reliable load that allows players to use their amplifier for silent recording, direct recording, or signal routing while protecting the amplifier's output stage.
The LB-120 features a balanced XLR direct output with speaker simulation, delivering a cabinet-emulated signal suitable for mixing consoles, audio interfaces, and recording equipment. A ground lift switch helps eliminate unwanted hum, while the parallel speaker output allows a speaker cabinet to remain connected when desired. The unit is available in dedicated impedance versions, making it important to match the load box to the output impedance of the connected amplifier.
Built in a rugged metal enclosure, the Koch LB-120 is well suited for studio use, live performance, and situations where authentic tube amplifier tone is required at controlled or silent volume levels.
