The CX408P is a professional 4-input and 8-output audio processor designed for advanced sound system management, signal processing, speaker optimization, and professional audio installations. It is suitable for stages, bars, conference venues, auditoriums, hotels, entertainment spaces, commercial buildings, and other high-end sound reinforcement applications where precise control of multiple audio channels is required. The processor provides four balanced analog inputs and eight balanced line-level outputs, allowing a relatively small number of input sources to be routed and processed across multiple amplifier or speaker channels.

The CX408P incorporates a high-performance ADI SHARC 21489 450MHz DSP with 24-bit/96kHz AD/DA conversion, providing detailed digital signal processing and high-quality audio reproduction. Its processing architecture includes 15-band parametric EQ on inputs, 10-band PEQ on outputs, dynamic EQ, high-pass and low-pass filters, matrix mixing, delay, and FIR-based linear-phase processing. These functions allow installers to precisely tune loudspeaker systems, correct frequency response, manage signal levels, and optimize audio performance for different room acoustics and speaker configurations.

The processor also supports multiple professional signal formats and control methods. Each input can support AES3 signal switching, while optional 4×4 Dante network audio provides integration with compatible digital audio networks. The built-in FIR designer can automatically assist with linear magnitude and phase correction, simplifying speaker parameter configuration. USB, TCP/IP, and RS232 interfaces allow connection to a computer or third-party central control system, while MConsole software provides a convenient graphical interface for configuration and system management.
