I have a question: I was approached by the band instructor at my son's middle school. At the school they have an auditorium which seats maybe 8oo total with a balcony. Plaster & wood construction. Anyway, the school wants to replace the old sound re-enforcement console with something new. He asked me to look into the particulars. They have concerts (small & large ensambles), choir groups, school plays & assemblies. I have no expertise in choosing FOH boards & thought I could get some guidance from our group. Are there virtual units available that could be operated from a laptop? Do I need to look at regular boards? Is 16 channels appropriate? I'm starting from scratch & probably they are working on a limited budget. They will keep the current power amps & speakers.
