Marketing Information |
The DP-K1 DIGITAL SIGNAL 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-K1's modular design supports up to
eight mic/line 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. |
