Features Rack-mount digital mixer processor for installed sound applications such as houses of worship, sports facilities, convention centers, airports and others. Automatic Resonance Control ARC Advanced new measurement and processing algorithm improves speech intelligibility and sound quality in facilities with challenging acoustic environments. Automatically identifies room mode frequencies and applies an inverse response curve to compensate for the measured room response. Modular design allows versatile configurations up to 8 inputs and 8 outputs modules not included. Description Product Description The DP-K1 DIGITAL MIXER PROCESSOR is the ideal solution for a wide variety of installed sound applications including houses of worship, sports facilities, convention centers, airports and many others. The DP-K1s modular design supports up to eight micline inputs and eight line outputs with flexible contact-closure remote control. The advanced new Automatic Resonance Control ARC measurement and processing algorithm from TOA, improves speech intelligibility and sound quality in facilities with challenging acoustic environments. ARC automatically identifies room mode frequencies and applies an inverse response curve to compensate for the measured room response. Additional audio processing tools include multi-band parametric filters, compressors, limiters, noise gates, crossovers, delays and more. Full input-to-output matrixing allows users to store and recall any input to output combination for multi-zone or room-combining applications. The unit is programmed via PC control software and includes a built-in network interface for remote access. The DP-K1 is covered with a five year product warranty.
