The 3.6SP (3-in x 6-out) is 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.<br>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.
