ASHLY 24.24 M Matrix Processor

 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?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-3 to control levels and presets from a remote location. These accessories mount in a standard wall box.
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.

Based on a two-in, six-out topology, the DC-One is designed primarily for users of small-to-medium sized sound systems in both mobile and installed applications. While the unit is an all-new development based on a powerful SHARC processor, it is 100 percent compatible with all settings from other Electro-Voice signal processors. A large part of DC-Oneʼs development was aimed at ensuring that users can easily handle its serious digital horsepower and high-end audio performance. Free. PC-Editor software is available, or the DC-One can be operated via the front panel.   A/D Conversion    24-Bit Delta-Sigma

Providing 48-bit filter algorithms, 24-bit AD/DA conversion and a dynamic range of 115 dB, the DSP 244 sets new standards for digital loudspeaker controllers and processors. The DSP 244 is an universal Digital Sound System Processor that provides 2 inputs and 4 outputs; plus internal summing of the inputs 1 and 2. Via matrix it is possible to assign the outputs to any input or to the sum of the inputs. It is further possible to establish the following configurations: Stereo or Dual 2-Way systems, 3-Way + Direct and 4-Way systems, each with Mono Subchannel, but also full range systems. High and low-pass filters are provided for the frequency crossover functions in all operation modes. The selection includes Linkwitz-Riley, Butterworth and Bessel type filters with switchable slopes between 6, 12, 18 and 24 dB/oct. A huge number of additional filters offers extremely flexible correction of the frequency response. Each input incorporates a 5-band equalizer, allowing to assign high and low-pass, high and low-shelving or parametric peak-dip filters to its individual filter sections. Next to the frequency crossover filters, four additional filters are employed in each output channel, which also can be set to work as high or low-pass, high or low-shelving filters, parametric peak-dip filters, or all-pass filters. Additional filtering is provided through 2. order high-passes for the realization of B-6 alignment, or special LPN-filters (Low-Pass Notch filters) for correcting the frequency and phase responses of optimally vented woofer cabinets. Each channel additionally provides a delay, a polarity switch, a programmable level control and a digital compressor / limiter while the master delays are located in the input channels.
