Bộ xử lý tín hiệu audio kỹ thuật số TOA 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.
