The 4.8SP (4-in x 8-out) is a great choice for both live sound and use in fixed installations like worship facilities, schools and performance spaces. The SP Series has 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 DSP via Ashly's Protea software-and set a password-secured security system to prevent unauthorized tampering.
