Yup. Ganun naman talaga ang acoustic treatment. A little at a time. Gradual.
Filled up the hall with a lot of people Chief (over 2200+)...temporarily used our current system made up of 6 dual 15" speakers ( 2 on the left and right side walls and 1 each on the front L and front R of the stage), 2 W-Box Subs, Single 15 inchers for outside mix and 2 as stage monitors.
As expected, the ceiling helped. But we know that the hall is far from ideal.
I just played with the gain settings for each amp starting with the fronts at the highest level 3 o'clock, then the mid section around 12 o'clock and the closest speaker to the main mixer at the back, 10 o'clock.
Reverberation is still high but we were surprised to hear intelligible speech...will most likely start installation of rockwool panels within the next 2 weeks.
Happy Easter everyone!
