DIGITAL AUDIO PROCESSOR

DP-K1

DESCRIPTION

The TOA DP-K1 is an easy-to-operate digital audio processor equipped with gain, equalizer, crossover, compressor, noise gate, matrix, delay and Automatic Resonance Control functions. The advanced new Automatic Resonance Control (ARC) function enables the DP-K1 to automatically measure and process the acoustic response characteristics of complex environments and provide compensatory parameter settings to improve speech intelligibility and sound quality. This latest addition to the TOA line of digital audio processors makes it easy to bring optimal sound enhancement even to acoustically challenging venues such as houses of worship, sports facilities, convention centers, airports, and many other venues. The DP-K1's modular design supports up to eight mic/line inputs and eight line outputs with flexible contact-closure remote control.

FEATURES

●

Advanced new Automatic Resonance Control (ARC) function improves system intelligibility.

• The ARC function automatically measures frequency characteristics of the broadcast area and finds resonant frequencies.

•Automatically creates a filter curve that curbs unwanted resonant frequencies for the measured room response.

•Improves speech intelligibility and sound quality in facilities with challenging acoustic environments.

• Room mode compensation

• Unlike earlier, time-consuming manual adjustment methods that required electroacoustic engineers, operation is quick and easy.

• Fully comprehensive operating capability means no dedicated device is required

●

Digital audio processor has built-in rack-mount brackets (3 RU, EIA standard 19 inch rack mount width) for commercial sound applications such as houses of worship, sports facilities, convention centers, airports, and many others.

●

Cost-effective modular design — up to 8 inputs and 8 outputs

• Users can choose from among a variety of optional modules.

●

Up to 16 different user-created combination configurations are possible.

●

Built-in gain, equalizer, crossover, compressor, noise gate, matrix and delay audio processor functions

●

Eight bus matrix allows flexible input-to-output signal routing for zoning or room combining.

●

PC software for offsite programming and settings

●

Network interface for remote programming and maintenance

●

Network ports are available on both front and rear panels.

●

8 internal memories for storage and recall of different signal routing and parameter configurations.

●

Preset knob-lock function prevents accidental errors during operation.

●

Input and output channel indicators

●

Cooling fan ensures continuous, reliable operation.
