The DSP4x4 is the first standalone Digital Signal Processor that Stewart has ever produced. This compact DSP was design to address the multitude of problems encountered in typical installations impacting sound quality. Set and forget configuration is done through the front USB port via an intuitive windows program. This downloadable program makes setup fast and repeatable with the ability to save and copy programs to multiple units for labor savings. To help minimize setup errors, all DSP block values appear with a simple mouse over and mute or bypassed blocks are clearly tagged. The RS232 allows for preset programs to be used for applications like room combining and volume control from a wide range of devices. The inputs can be line or mic level with 24V phantom power available. Simple, versatile and powerful are all attributes of this compact DSP. You won't find a more flexible signal processor in a comparable package on the market today.
