Heilbronn/Germany, December 09, 2008 - - At the upcoming Integrated Systems Europe (ISE), taking place from February 03 – 05 in Amsterdam, Shure will present a selected product portfolio at booth no.3B120. Among products shown will be Shure’s recently launched UHF-R micro-bodypack and Microflex microphone additions, as well as, a selection of QSC products distributed exclusively by Shure Distribution in Germany and the UK including the new AcousticDesign subwoofer.
With the launch of the AcousticDesign subwoofer at the show, QSC rounds out the AcousticDesign line of surface and ceiling mount speakers which offer both modern design and impressive sound quality.
Shure’s new UR1M micro-bodypack is the recent addition to its premium UHF-R wireless system. Tailored for applications where inconspicuousness and maximum performance are a must, the UR1M offers superior wireless audio in an ultra-compact package weighing just 62 grams and approximately half the size of most standard bodypacks.
