Audio (3) System Performance <br />1) Predicted broadband variance is +/- 2.5 dbA across the audience area (exceeds 3.0 db maximum variance)2) The above graph shows maximum system output level, with the quietest area still capable of 104 dbA, 360’from the stage, exceeding the 100 dbA minimum. This assumes little or no wind, but can be extended usingdelay towers as-needed <br />1) Predicted tonal response is very similar from front to back in the audience area.2) Difference in the low-mid range (63hz - 500hz) will be mitigated using beam steering, by implementing a seriesof all-pass filter in each speaker, to steer more low energy toward the back of the audience.3) Difference in mid/high frequency information, 1.5khz - 20khz, to be mitigated using FIR filters applied to eachindividual speakers in the array. Each FIR filter has a decibel range of 26db available, which is more than thegreatest variance in the high frequency range4) RD Net control will monitor amplifier usage, speaker angles, and temperature at all times5) SMAART will be used for testing, measuring, and monitoring for eventa. SPL log report will be available to ensure safety of listeners and adherence to local ordinance6) System power requirements are relatively lowa. Mains PA fits into 6 x 20A/120V circuits with headroomb. Subwoofers on the ground will also fit into 6 x 20A/120V circuitsc. Control systems and stage power will fit into 3 x 20/120V circuits with headroomd. Audio system at maximum usage will be less than 100A peak poweri. Real-world power draw in show not likely to exceed 50A / leg of 3 phase ‘y’ system, and easilyfits on a 45 KVA generator, where system peak inrush current will not exceed rated constantdraw of 116A, or mains breaker of 125A7) This PA system is easily trucked, deployed, and managed by a crew of 3 people
