The 442 signal chain consists of two 2x2x1 switchers (2 amps, 2 FX loops, 1 cabinet). If the stereo mode is active these two switchers operate completely independent from each other. If the stereo mode is inactive the 442 works like a 4x4x2 switcher by interconnecting both switcher’s FX loop bus and speaker bus.
The main part of the screen shows information about the connection status of the devices. Devices are amplifiers, cabinets, effect pedals or effect rigs. The device status area consists of a schematic representation of the analog path through the 442, starting from the input jacks on the left, followed by rigs, amplifiers and cabinets.

Stereo Mode In the stereo mode the 442 is internally configured to work like a dual 2 amps, 2 fx loops, 1 cabinet switcher. Therefore two amplifiers and two cabinets can be selected at the same time. Amplifier 1 and 2 can be routed to cabinet 1, while amplifier 3 and 4 can be routed to cabinet 2.
Submenue “Presets” The Presets menu gives you an overview over all presets saved in the 442. You can recall a preset directly from here. It is arranged in 10 banks with 10 presets each.
Presets The 442 has a non-volatile memory to store up to 99 presets. Coming from the factory all presets are empty. Selecting an empty preset will not change the current status of the 442. You can see the status of each preset in the Presets Menu.
