DP-SP3

Digital Audio Processor

The DP-SP3 is a 1U rack mountable Digital speaker processor having 2 inputs and 6 outputs. It features digital signal processing functions such as Equalizer, Crossover, Matrix, Compressor, and Delay. Other functions include input PAD, analog output attenuator, output MUTE, EQ characteristic library for TOA speakers, and contact input terminals. When connected to a LAN, settings and operations of the DP-SP3 can be performed on a PC with the supplied DP-SP3 PC Software installed. It can be mounted in an EIA component rack (1U size).

  • Digital Speaker Processor for clear, high-quality and realistic sound, with a full sense of presence
  • Essential audio processing tools: Filters, Compressor, Parametric Equalizer, Output Delay and Mute
  • 10 filters on each input and 12 filters on each output, each filter type selectable
  • Any combinations of parametric equalizer and high/low pass, and high/low shelving filters, as well as all-pass, notch filters and CD horn equalizer are possible
  • 2 inputs & 6 outputs, processor can work with a 3-way multi-amp system
