Class:
Description Type: Multi-Effects Processor Form Factor: Rack-Mountable Effect/Enhancement: Graphic Equalization, High-Pass Filtering, Low-Pass Filtering, Noise Gating/Expansion Number of Channels: 4 in 8 out XLR Brand: Ashly Model: Ashly Protea 4.24C MPN: Does not apply UPC: Does not apply
Up for auction and for your consideration is a Ashly Protea 4.24C in excllent lightly used condition with Heavy Duty, Shielded Power Supply. No problems found while testing. The channel A for XLR cable has the metal release tab missing but is easy enough to get around (See Pictures). Everything works as expected. You get what is in the actual pictures of the item in this listing with the power supply cable. You can download the manual online Free from here http://ashly.com/wp-content/uploads/2015/08/protea-424c-digital-crossover-r02.pdf

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.
