We use a Yamaha EMX5014C Powered Mixer 500watts 2 Nady 402 Group 4 VHF Lavalier Wireless Microphone Systems hs auditorium [60x90x14’ceiling height] [raked seating] [20x40 stage] [10ft wings] 12 ft stage ceiling painted cinderblock sidewalls, front and back walls decorative wood The pit is on floor level in front in between the stage and front row. Bose 802 speakers [20yrs old], 8 ft in from the corners of the stage, 10 feet off the floor, flanking the proscenium. I need more volume for the actors. The orchestra plays beautifully but loudly. Because of the type of ceiling we have, I cannot move the 802’s over the pit. I can center them over the proscenium. Where can I add extra speakers? I’m on a tight budget. [important fact I missed the stage is 30 inches above the auditorium floor] I have extra power amps and various shure hanging and floor mics.
