Description
Quality theater audio for the desktop has arrived. Using an internal Dolby® Digital surround processor, the Digital BA7500 delivers 5.1 movie audio from your PC’s DVD-ROM without the need f or a separate receiver or decoder . Four Boston SST™ (Slimline Speaker Technology™) satellites, an amplified subwoofer and the processor’ s “virtualized” center create six distinct cinema sound fields . With a 4­channel sound card, it brings multi-channel PC gaming to a new level of realism. As a stereo music system, the BA7500 has maintained the highest level of fidelity, equal in performance to some shelf monitors.
Building on Boston’s prov en 6½" bandpass subwoofer , the technological highlight of the Digital BA7500 is the four SST satellites. Boston sets the standard: The technology f ound in the SST’s allows us to deliver the same high-fidelity audio found in Boston’ s larger home theater products and still maintain a sleek, attractive profile. Front pedestal stands, rear tower stands, a desktop audio control pod and e xtra-long surround cables make f or easy 3D positioning and operation. Desktop controls include Master Volume, Surround Volume, Surround Balance and Subwoofer Lev el. Each satellite is protected by magnetic shielding to prevent video interference .
