Product Overview
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-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.
The DP-K1 is a 3U rack mountable Digital Audio Processor. It features an Automatic Resonance Control function that automatically generates an optimum filter curve to improve sound clarity after measuring the acoustic characteristics in architectural space. It permits flexible configuration of inputs and outputs, from 2-IN/4-OUT to 8-IN/8-OUT using the optional modules. Each function is set by a PC using the dedicated software. The settings can be stored in the unit's internal memory and the stored preset memories can be recalled from the unit without connecting the PC.
