Ashly Audio

A powerful tool for live sound control.

The Ashly Protea 4.24C is a 4-input, 8-output speaker processor coupled with a user interface that is so easy you won't even need the manual to set up your system. The Protea System II 4.24C Digital Crossover/System Processor has all the audio processing tools needed for precise crossover and sound control. Each input allows you to control gain, delay and six parametric, low or high shelf filters. In addition to setting crossover frequencies, each output may be assigned to any one or a combination of inputs, allows you to program four parametric, low or high shelf filters, delay for time delay adjustments, output gain, reverse polarity and a compressor/limiter for speaker protection. All this in a one rack space with XLR input and output connections. You may also program and control the 4.24C with Ashly's Protea System Software (Windows 95, 98, 2000, XP and NT platforms), AMX NetLinx, MIDI or SIA-Smaart software. In all, the Protea 4.24C is a powerful tool for use in fixed installation and live sound applications.
