ADL Releases Penteo 3 Pro, a New Stereo-to-5.1 Surround Plug-in, and Appoints
GC Pro As Exclusive U.S. Distributor

— GC Pro continues to serve the post-production/pro audio markets by offering clients the new groundbreaking Penteo up-mix plug-in —

WESTLAKE VILLAGE, CA, January 17, 2013 — Guitar Center Professional (GC Pro), the outside sales division of Guitar Center that focuses on the needs of professional users, has been appointed the exclusive U.S. distributor of a new plug-in from ADL, a leading developer of proprietary solutions in stereo-to-5.1 surround technology. The plug-in, called Penteo 3 Pro, discretely converts stereo to 5.1, offering very fine control over sound image placement, thereby creating the warmest and best-sounding surround experience. Designed for post-production, broadcast and DJ professionals, Penteo 3 Pro’s proprietary algorithm does not artificially manipulate the sound. The listener hears a perfect surround experience with zero sonic artifacts, and uniquely, Penteo is 100% ITU down-mix compatible to the original stereo. Featuring an intuitive visual interface modeled after vintage gear, the plug-in offers six automated preset modes as well as manual fine-tuning for discerning ears. Penteo 3 Pro will be available beginning February 2013 online at and, with demos available at multiple GC Pro locations.

Jeffrey Read, President, Penteo Surround Inc., stated, “We wanted to partner with an organization that knows all the main players in the post-production and pro audio market sectors – one partner that could give us national coverage in major markets like L.A., New York, Chicago, Atlanta and Nashville as well as the smaller regional markets. We are thrilled to be represented by a company that understands the full spectrum of post-production and pro audio worlds. GC Pro is a fantastic organization that meets all of these criteria, and we look forward to a fruitful relationship with them and the wider Guitar Center organization.”

GC Pro Vice President Rick Plushner added, “We have seen a steady increase in demand for 5.1 content, especially among our post-production customers, so it feels very appropriate for GC Pro to represent Penteo. The sound quality offered by Penteo 3 Pro is astounding. GC Pro did extensive listening and testing with our engineering, sales and management teams, and to everyone’s ears, Penteo is a superb piece of technology. There are thousands of potential uses for this plug-in, and we are excited to see it put to great use. We also look forward to offering demonstrations at our locations around the country, especially our new high-tech demo facility in Hollywood."
