The Protea 24.24M is now AMX NetLinx and ACCENT3 compatible.

The Protea 24.24M Matrix Processor uses modular expansion cards to provide up to twenty-four channels of audio matrixing and processing. The base unit offers a four-input/four-output configuration. Each input and output expansion card has an individual DSP processor allowing you to expand the base unit's total inputs or outputs four channels at a time. These cards are easily installed in the field without the need to reprogram the device. Matrixing allows you to route any input to any output and control individual levels once they have been assigned. Fixed path architecture and extensive processing power per channel will reduce the amount of time it takes to set up your system.

All programming is accomplished using Ashly's Protea System Software on a PC platform. No front panel controls and multi-level software security assures you a tamperproof audio system. Whether you are designing or installing a system for corporate boardrooms, restaurants, courtrooms, houses of worship, left/center/right theatres, auditoriums or conference centers, the Protea 24.24M will more than satisfy your requirements for any zoned system requiring input/output matrixing with signal processing. The 24.24M Matrix Processor's firmware is supported by flash making the device capable of field upgrades using Ashly Audio&339;s Protea System Software. Reprogramming is simple and takes only minutes.

Input channel processing blocks include Mic Preamp with Phantom Power, Gain, Delay, fifteen EQ Filters, Gate, Autoleveler and Ducker. Inputs may be configured as either mic or line level.

Output channel processing blocks consist of a Cross Point Mixer, HPF/LPF, Delay, fifteen EQ Filters, Gain and Limiter. The cross point mixer in the output section allows you to route any input to any output at any level and mute any input at any output without affecting the true input configuration. The HPF/LPF block offers Bessel, Butterworth and Linkwitz-Riley filters with 12, 18, 24 and 48dB/ octave slopes.

You may use the WR-1, WR-2 and WR-5 to control levels and presets from a remote location. These accessories mount in a standard wall box. (You may also use the WR-3 and WR-4 even though they are discontinued accessories).

Euroblock connectors for audio, preset recall, dc remote level control and data in/out connections are on the rear panel. Standard 9-pin RS-232 data connectors are located on the front and rear panel to allow all functions to be controlled either by a PC or a dedicated control system.

Thirty-five presets are available to set and store your own system requirements. When using Protea System Software, full system setup and control is quick and easy with the capability of storing multiple system configurations as backups or for future reference.
