About Ashly ne4400

Under the umbrella of advanced audio processing solutions, the ne4400 Network Enabled Protea DSP Audio System Processor stands out as a sophisticated, high-quality, and professional choice. This innovative system is designed to streamline the process of connecting and controlling an audio processor for networked systems.

The ne4400 is not just a digital signal processor; it's a comprehensive audio management tool. It offers easy setup and control using standard 10/100 Ethernet protocol and Protea ne Software, eliminating the need for special outboard control units. This processor is designed with four AES3 inputs and a CNM-2 CobraNet option card, making it capable of handling multiple audio sources simultaneously.

The ne4400 is more than just a processor; it's a library of DSP signal processing capabilities. It utilizes multiple SHARC 32-Bit processors with sample rates of either 48kHz or 96kHz. The processing blocks include a matrix mixer, a full array of graphic, parametric and all pass equalization, and crossover filters. This includes 8th-order Butterworth, Bessel, Linkwitz-Riley, and notched Linkwitz-Riley filters.

The Protea Software Suite, included with the ne4400, offers an advanced automatic feedback suppressor, FIR filter capability, gain sharing automatic microphone mixing, ambient noise sensing and level adjustment, autolevelers, compressors, matrix duckers, limiters, frequency-keyed noise gates, and signal delay up to 1,365ms on every channel. It also includes your choice of sinewave, pink or white noise generators.

The ne4400 is designed for hot-plug software control, allowing you to plug any function into any channel block even when running live audio, with no recompiling necessary. It features automatic DHCP network IP configuration, reducing network setup time. The multi-level software security with password access ensures a tamper-proof audio system.

This professional-grade audio system processor is ideal for use in live sound reinforcement, recording studios, and installed sound systems. It's designed to be integrated into a networked audio system, providing remote control and monitoring capabilities. The ne4400 is the perfect choice for audio professionals who need to manage and control multiple audio devices in a networked environment.

The ne4400 Network Enabled Protea DSP Audio System Processor is more than just a tool; it's a solution for advanced, professional audio processing.
