dB Technologies used this year's PLASA Show to launch the DVA (Digital Vertical Array) active, compact line array system. Designed for small- to medium-sized venues, the DVA comprises two boxes, the DVA T4 mid/high and the DVA S20 sub. Both boxes are self-powered with Class T digital amplification and provides 15° of horizontal dispersion. dB also announced the PU850 UHF wireless microphone system which provides options for handheld, lavalier, guitar and headset microphones.
