The Ashly Protea System II 4.24 GS is a dedicated digital signal processor configured as a graphic equalizer system, operating as a slave unit within the comprehensive Ashly Protea System II networked audio ecosystem. This unit is engineered for large-scale, fixed-installation sound reinforcement where precise, multi-zone equalization and system control are paramount. The designation "4.24 GS" indicates its core configuration: 4 input channels, 24 output channels, and a processing focus on Graphic Equalization. Its primary function is to provide detailed, 1/3-octave graphic EQ control on each of its 24 outputs, allowing audio system designers and technicians to meticulously tune each speaker zone or output path in complex venues like performing arts centers, stadiums, houses of worship, and corporate auditoriums to correct for room acoustics and achieve a flat, uniform frequency response.

As a slave processor, the 4.24 GS does not operate in isolation. It must be connected to an Ashly Protea System II Master Controller unit via a proprietary high-speed data network. All programming, real-time adjustments, and system control are executed from the master controller using Ashly's Protea Software on a connected computer. This master/slave architecture allows multiple slave units (like additional 4.24 GS or other processors) to be combined, creating a massively scalable processing system with centralized control. Once programmed, the slave unit can operate independently, but any configuration changes require communication through the master. The unit provides full DSP capabilities beyond graphic EQ, including parametric EQ, dynamics processing (compressors, limiters), delay, and crossover functions, all assignable per channel via the software. Housed in a single rack-unit, robust chassis, it is built for 24/7 reliability in professional installed sound applications.
