If you use those plastic insulation troughs and overlap the top one of the lower ones even if rain should sneak up past the shingles, past the builders felt it will fall on the plastic trough and be carried out past the building envelope.. 1  Reply. 2  Reply to Original. 3  Print this page. 4  Email this Message.
Double-sideband suppressed-carrier transmission. Double-sideband suppressed-carrier transmission (DSB-SC) is transmission in which frequencies produced by amplitude modulation (AM) are symmetrically spaced above and below the carrier frequency and the carrier level is reduced to the lowest practical level, ideally being completely suppressed.
Servo & DSP-technology. Servo technology utilizes patented (U.S. Patent No. 8,300,872) Direct Position Feedback sensors built inside the loudspeaker. Direct position feedback scheme enables the usage os Active Suspension Compliance Management (ASCM) which is a revolutionary technology in small loudspeakers. With ASCM, the cumulative spectral decay is ultrafast (free of resonances) and the speaker can reproduce several octaves lower than conventional closed or bass-reflex systems without bass-lag.
