The Ashly Protea ne24.24MT Matrix Digital Signal Processor with 16x4 I/O and GPO Logic Card is a specialized configuration of Ashly's versatile matrix processor, tailored for applications requiring both sophisticated audio routing and integration with external control systems. This variant provides a substantial 16-input by 4-output analog audio matrix, offering extensive connectivity for sources while dedicating outputs to key zones or processing busses. The inclusion of a General Purpose Output (GPO) Logic Card significantly expands its functionality beyond audio, enabling the processor to trigger external events based on audio activity or preset changes, such as turning on lights, lowering projector screens, or muting other devices in response to a microphone being activated.

At its core, the unit delivers the full power of the Protea System DSP, with comprehensive processing available on every input and output channel. This includes microphone-specific features like gating and AEC (Acoustic Echo Cancellation) on inputs, and detailed EQ, compression, limiting, and crossover filters on outputs. The large 16x4 matrix allows for incredibly flexible routing, making it suitable for complex installations like courtrooms, large conference centers, or broadcast facilities where numerous microphones, program sources, and recording feeds must be managed and directed to various destinations. The software-based design allows for the creation and recall of multiple presets, enabling the space to transition seamlessly between different operational modes.

The GPO Logic Card adds a layer of system automation by providing configurable relay or contact closure outputs. These can be programmed within the Protea software to activate based on virtually any condition, such as a specific input channel exceeding a threshold (e.g., a gooseneck mic being used) or when a particular preset is loaded. This transforms the audio processor into a central command point for basic room automation, enhancing the user experience and system efficiency. Housed in a 1U rack chassis with dual Ethernet ports for control, this version of the ne24.24MT is a powerful tool for integrators designing highly integrated, automated AV environments.
