The faceted cut-glass enclosures are a fi rst in desktop audio systems, and will integrate beautifully with home and offi ce dcor. Digital power and DSP The GLA-55 system delivers with a pow

9、erfully tuned digital audio path. The clean and compact digital amplifi cation, coupled with DSP (digital signal processing) equalization, effi ciently provides GLA-55 transducers with cool-running power. Subwoofer output The GLA-55 systems packs a powerful punch on its own but, for added bass respo

10、nse, the subwoofer output allows connection to most stand-alone subwoofer systems. Advanced technology GLA-55 speakers feature many proprietary technologies to provide the highest quality sound, including astonishing bass and clear, accurate sound in any location. AtlasTM AL and CMMD Transducers The

11、 CMMD drivers provide accurate high frequencies but are also capable of low-frequency extension to four octaves; the Atlas AL drivers are capable of nearly 1 peak-to-peak travel for tight, accurate bass reproduction. Their pairing provides a full, rich frequency response from the lowest bass to the

12、highest highs. Slipstream Port Design The GLA-55 port minimizes boundary layer separation, providing high-output bass with low distortion. COE (Computer-Optimized Equalization) The GLA-55 system equalization is computer-optimized to provide a rich, complete sound- stage over a wide range of listenin

13、g positions. OCT (Optimized Compression Topology) GLA-55 speakers utilize a proprietary compression technology, which ensures clean, accurate sound at high output levels.
