The CX-C6688 is a professional 8×8 audio matrix processor designed for advanced audio routing, signal processing, multi-zone sound distribution, and professional sound reinforcement systems. It provides 8 analog audio inputs and 8 analog audio outputs, allowing multiple microphones, line-level audio sources, amplifiers, and speaker systems to be connected and managed through a flexible digital processing platform. This type of matrix architecture is particularly useful in installations where different audio sources need to be routed to different output zones or speaker systems.

The processor combines high-quality 24-bit/48kHz AD/DA conversion with a 40-bit floating-point DSP operating at 400MHz, providing detailed and flexible digital audio processing. Its comprehensive matrix mixing architecture includes input and output gain control, equalization, noise gate, compressor, limiter, AGC, crossover, and delay functions. These processing tools allow installers to independently optimize different input sources and output channels according to the acoustic characteristics and requirements of each installation.

The CX-C6688 also provides extensive control and configuration capabilities. TCP/IP, RS232, and RS485 interfaces allow the processor to be connected to computers, central control systems, and other compatible AV equipment. Its GPIO interface supports 8-channel scene switching, while up to 60 scene presets can be stored for quick recall of different system configurations. Output channel delay can be adjusted up to 1500ms, providing additional flexibility for speaker alignment and room optimization.
