The Ashly Protea ne24.24MT Matrix Digital Signal Processor with a 12x4 I/O and GPO Logic Card configuration is a specialized digital audio hub designed for environments that combine extensive audio source management with external system control. This model provides twelve balanced analog inputs, capable of handling a large number of microphones and line-level sources, and four independent analog outputs. The inclusion of a General Purpose Output (GPO) Logic Card significantly expands its functionality, enabling the processor to trigger external devices—such as relays, lighting, or motorized screens—based on audio activity or preset changes. This makes it ideal for complex, integrated installations in courtrooms, legislative chambers, broadcast studios, and performance venues where audio events need to automate other room systems.

At its audio core, the unit leverages the full power of the Protea System DSP, offering comprehensive processing on every input and output channel. Input channels can be configured with gain, parametric EQ, dynamics, and Acoustic Echo Cancellation (AEC) for clear voice reinforcement. The four output channels each provide detailed parametric EQ, precise delay, compressor/limiters, and crossover filters. The substantial 12x4 matrix allows for flexible routing of the many inputs to the key output destinations, such as main speaker zones, record feeds, or broadcast mixes. The "MT" firmware supports multiple, recallable presets for different room configurations or event types.

The GPO Logic Card adds a vital layer of system integration by providing configurable contact closure outputs. These relays can be programmed within the Protea software to activate based on specific triggers, such as a particular microphone being unmuted, an audio level threshold being exceeded, or a preset being recalled. This transforms the audio processor into a central command point for basic room automation. Housed in a 1U rack chassis with dual Ethernet ports for network control, this version of the ne24.24MT is a powerful tool for integrators designing highly responsive and automated AV environments that require both sophisticated audio management and physical control outputs.
