DP-K1 CU
Digital Audio Processor
DP-K1
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.
- Digital signal processor with max. 8 inputs and outputs
- Antiresonance function for 8 channels
- A variety of filters, dynamic (noise gate, compressor), delay, crossover, matrix
- Modular inputs and outputs for easy adjustment of the system
- Different input and output modules available
- Adjustment by PC via LAN possible
- Easy to use and many automatic functions
- Rack-mountable

Modular digital signal processor with anti-response function for up to 8 audio inputs and 8 outputs. Through the feedback function is achieved depending on the acoustic environment a much clearer sound and thus increases the intelligibility. Automatic measurement of the room up to 8 measurement locations with analysis of the critical room resonances. Up to 8 zones can be individually adjusted.
Each signal path has 18 filter, of which 12 are free configurable and programmable from the following types: parametric EQ, high, low and all pass filter, notch filters, shelving filters for bass and treble, CD Horn equalization.
