DP-SP3

DP-SP3 Digital Speaker Processor

DP-SP3 CU

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).
