Grund Audio Design Debuts DP-26C Loudspeaker Processor Grund Audio Design, a manufacturer of loudspeaker and signal processing products for the audio professional, announces the new DP-26C loudspeaker processor. Featuring a wealth of DSP (digital signal processing) capability, including true 96 kHz resolution, versatile two- in / six-out functionality, operation from an external personal computer or via front panel access, and a wealth of additional processing choices, the new 1RU, rack mountable DP-26C is the ideal tool for a wide range of loudspeaker management tasks-for both live sound and fixed installation applications, the company says. Among the DP-26C's most notable features is its ability to manage phase response. It 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. Unique among the current field of loudspeaker processors, the DP-26C's ability to optimize the loudspeaker system for both SPL (sound pressure level) and phase provides today's audio engineer the ability to ensure maximum performance from the sound reinforcement system, reports the company. Another key aspect of the DP-26C is its versatile user interface. With the ability to define system parameters via an external Windows PC, the operator is able to quickly see and adjust a multitude of settings while maintaining a "global" visual perspective of the system. The computer requires minimal processing capability as the actual audio processing is handled onboard the DP-26C. The DP-26C's software interface runs on Windows XP, Vista, and 7. Macintosh software is coming soon. 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. For remote control purposes, the DP-26C can be accessed via USB or, for longer cable deployments, a USB to RS485 converter / adapter can be used. With a USB to RS485 adapter, for example, the DP-26C can reside on stage while adjustments to the processor are made from the FOH (front of house) mix position-a thoughtful feature for the live sound professional. Frank Grund, president of Grund Audio Design, says, "The DP-26C brings a wealth of features and functionality that make it a terrific choice for both live sound and fixed installations. The processor's ability to impact phase response is quite unique and, with the software front end, system control is quite intuitive. Similarly, the unit's 6 fully independent outputs enable audio engineers to take full advantage of the processors strengths. The processor offers a rich feature set at a highly competitive price, all of which translates to excellent return on investment. I'm confident prospective customers will find the DP-26C a compelling value."
