The P4800 System Processor is a 4-input, 8-output digital audio processor. It performs all the necessary functions between the mixers and the power amplifiers in small to medium sized sound systems. Using the P4800's drag-and-drop Graphical User Interface, processors can be placed anywhere in the signal path. The 4-by-8 matrix mixer allows any or all inputs to be routed to any or all outputs with additional controls for levels and polarity. The P4800 can store up to 128 configurations that can be recalled using simple contact closures, MIDI, or RS232 commands.

Features:

• Processor blocks to handle post-mix and loudspeaker processing
  • Shure's acclaimed DFR (digital feedback reduction) algorithm
  • Parametric and Graphic EQ
  • 20 seconds of Delay
  • Mono and Stereo Compressors and Limiters
  • Gate / Downward Expander
  • Ducker
  • Automatic Gain Control
• 2 to 5-way Crossovers
  • A full 4x8 matrix mixer
  • Route any of the 4 inputs to any of the 8 outputs in any combination that you want
• Adjust signal levels at the crosspoints
  • 128 presets
  • Any preset can be as different or as similar to any other preset as you want
• Set up a series of optimized configurations in multi-purpose systems
  • External control options
  • DRS-10 - the easiest way to set up preset control
  • An accessory from Shure, the DRS-10 provides a 10-position rotary encoder and wall plate for selecting up to 10 presets
  • Control inputs
  • Use contact closures and potentiometers as preset, gain and mute controls
  • Logic outputs
  • Provide indication of preset changes and mutes
  • RS-232 control
  • Fully compatible with AMX and Crestron systems
