The flagship FREE THE TONE routing controller model ARC-3 has been reborn as the ARC-4. To accommodate increasingly complex systems, significant functionality has been added. It is now possible to name each bank and preset. A setlist mode has been added, which allows banks to be linked to setlists and freely combined. MIDI CLOCK support and a bank select function have also been added, making it easy to synchronize with external sequence software. In addition, it is packed with practical features that can be used in concerts, recording studios, etc., such as stereo loop, boost function, and phase inversion function. Please come and experience the quality of the ARC-4, the flagship model of the evolved ARC series. [Commitment to sound quality] FREE THE TONE has always been committed to "sound." At the heart of this is the Holistic Tonal Solution "HTS Circuit." The HTS Circuit, incorporated into the signal input and output of the ARC-4, allows the amplifier to always receive signals with a consistent impedance, regardless of the combination of connected effects units. This ensures that the effected sound and bypassed sound always maintain the same sound quality, fundamentally solving a problem that has plagued players for years. [Durability] We have conducted repeated usage tests in the harsh environments of concert venues, and based on feedback from a variety of locations, we have achieved durability that can withstand professional use. [Data Management] You can now assign names to presets, banks, and MIDI channels. By assigning names to presets using tone names and banks using song titles, and MIDI channels using the names of connected devices, data management becomes easier. We've also added a setlist mode that lets you freely rearrange banks and manage them as setlists. This feature significantly improves ease of use on concert tours. [MIDI function] Number of simultaneous MIDI program change number transmissions: 16 Number of MIDI control change numbers transmitted simultaneously: 8 ●Supports sending and receiving MIDI clock. *Reception is supported as hardware through. ■Reliability●To prevent sweat and other moisture from directly penetrating the internal circuit boards of the device, a lens is used for the LED above the foot switch, and a felt sheet is attached to the back of the encoder section. High-strength molded plastic phone jacks are used, ensuring peace of mind even during long-term use. [Easy to operate] ●Two dedicated displays are provided for presets and settings. By minimizing the number of levels in the edit menu, operability has been dramatically improved. You no longer need to spend a lot of time editing.
