The ARC USB is a wired, USB 1.1 advanced remote control that provides direct access to the most-frequently used actions and commands in TotalMix FX. It is compatible with all RME devices supported by TotalMix FX, via a Windows or Mac computer. The unit can also be connected directly to a Fireface UFX+ or Fireface UFX II, when operating these interfaces in standalone mode.
The ARC USB features a flexible Key Command Settings menu that lets you assign more than 36 different functions to any of the 15 keys. The behavior of each individual key/button can be changed between push, toggle, enable, and disable, depending on the base function. Available commands include Global Mute, Solo, Mute Group, Fader Group, Speaker B, DIM, Mute FX, Mono, Talkback, Snapshot 1-8, Mic Gain, and more.
A large rotary encoder wheel lets you change the value of parameters, and is also programmable in TotalMix FX. A set of stickers with all currently available commands is included and can be used to label the keys to reflect the current user configuration.
