Compatibility
The KHE ACS is compatible with all types of amplifiers and load devices, such as tube amps, solid-state amps, speaker cabinets, load boxes and power attenuators, up to 150 watts per channel.

Safety Features
The ACS is 100% safe for tube amplifiers: Load resistors protect the unused amplifiers and a load detection circuit supervises the cabinet jacks for the presence of a load device. If no load is connected, the cabinet outputs are automatically locked and excluded from the switching operation. This ensures amplifiers can never be activated without a real load connected.
