Protēa™ SP-series dsp loudspeaker processors

With active front panel controls and extremely intuitive user interface, Protēa loudspeaker processors thrive in a dynamic live sound environment. The front panel is hands-on and allows quick access to all control parameters by offering dedicated function buttons, eliminating the need for hidden sub-menus.
A backlit 2 x 20-character LCD displays channel and function settings. Dedicated front panel controls access all audio functions and system tools. There is a rear panel RS- 232 port in addition to the USB ports. Advantages of using the software include greater preset capacity, and a very intuitive visual representation of the audio routing and control process.

Our Protea™ System Processors (SPs) with DSP deliver premium sonic performance with an intuitive and user-friendly software platform.

The 3.6SP (3-in x 6-out) and 4.8SP (4-in x 8-out) are a great choice for both live sound and use in fixed installations like worship facilities, schools and performance spaces. Use the full Protea™ DSP Suite—crossover, equalization, compressor/limiter and delay—with up to 682ms on the input and the output, SPs serve as a front-end processor for delay stacks. The three inputs on the 3.6SP give you added flexibility, particularly when most other processors only offer two inputs.

SPs have front panel controls for immediate access to the settings during a dynamic, live performance. The front and rear panel USB ports allow you to program the processors via Ashly’s Protea™ Software—and set a password-secured security system to prevent unauthorized tampering.
