Rio1608-D

High-performance remote I/O for CL series and other digital mixing consoles.

• Sonic performance that brings out the best in any system

• Dante network protocol contributes to greater system scalability and flexibility

• Support for CL series consoles as well as other Dante based systems

• Automatic digital-stage compensation for analog gain changes (CL series only)

• Four models flexibly accommodate any system requirements
