Wealth if features from Grund Audio Design DP-26C processor
Grund Audio Design’s new DP-26C loudspeaker processor is a 1RU, rack mountable product, described to be an ‘ideal tool’ for live sound and fixed installation applications.
Featuring a ‘wealth’ of DSP capability, including 96kHz resolution and two in/six out functionality, the manufacturer states that one of the processor’s most notable features is its ability to manage phase response. The DP-26C offers provisions for defining a flat amplitude response with a 90-degree phase rotation at the selected frequency, as well as a flat amplitude response with a 180-degree phase rotation at the selected frequency.
Another key aspect of the new model is its ‘versatile’ user interface. With the ability to define system parameters via an external Windows PC, the user is able to quickly see and adjust settings while maintaining a ‘global’ visual perspective of the system. Audio processing is handled onboard the DP-26C, and its software interface runs on Windows XP, Vista, and 7. While the software interface is the preferred method for interacting with the DP-26C, full functionality is accessible via the unit’s front panel controls.
Featuring the ability to program each of the unit’s six outputs independently, the DP-26C provides the user with the ability to custom-tailor the device to the application environment. Input and output channels have delays up to 850ms, with steps of 22 microseconds. The processor also offers compression and brickwall limiting on each channel output, facilitating the ability to create multiband compression. The RMS compressor and peak limiter’s THR can range up to-30dBu.
For remote control purposes, the DP-26C can be accessed via USB or, for longer cable deployments, via a USB to RS485 converter/adapter. With a USB to RS485 adapter, the DP-26C can reside on stage while adjustments to the processor are made from the FOH mix position.
