The black PE-604BU Pendant Speaker 60W from Toa Electronics is a pendant speaker designed for the installations suspended from a ceiling. A directly-attached 16.4' (5.0 m) hanging wire allows the speaker to be suspended from high ceilings. The PE-604BU is driven on both high-impedance (100 V, 70 V and 25 V) and low-impedance (8 ohms) lines. The input power (impedance) can be easily changed at the upper side of the speaker. The Pendant Speaker is certified to UL 1480 UUMW and ULC-S541 standards. Using the supplied Gripple hangers will facilitate the speaker mounting height adjustment.
