Inquiry (采购产品): PA System I'm looking for a simple PA system for an indoor, noisy paper mill environment. I envision a single microphone in the existing centralized control room, an amplifier, and up to a dozen speakers at locations as remote as 300 ft away. Would you please direct me to such equipment on your website? I found speakers, but no microphones or amplifiers. **** Hidden Message ***** Andy Mott 54304 ALB Company: Georgia-Pacific Title: Project Engineer E-mail: andy.mott@gapac.com **** Hidden Message ***** andy.mott@gapac.com
