3 Primary System Design Constraints Generic fan-shaped auditorium with seating for 6000 (approx main floor, st balcony, nd balcony) Minimum SPL of 105 db at back row of (main floor) seating No more than ±5 db variation in SPL over the entire seating space for the 500 Hz, 1 KHz, 2 KHz, 4 KHz, and 8 KHz frequency bands Frequency response of 40 16,000 Hz ± 5 db %ALCONS no greater than 10% over entire seating space Minimum 48-channel mixing console Minimum of 4 separate monitor mixes (and corresponding monitor loudspeaker systems) Support for 20 compatible wireless microphone channels Good assortment of general-purpose wired and wireless microphone systems Digital media recording/playback capability All equipment mounted in rack cabinet(s) Budget of $500,000

4 Venue Illustration Seat ing Main Floor: st Balcony: nd Balcony: 1074 Total: 8256 Dimensions Stage Width: 100 ft Back Wall Width: 200 ft Length: 225 ft Height: 80 ft Surfaces Carpet with Padding on Floor Plaster, Smoothing Finish on Walls Drapes Fabric, Heavy weight on back wall

5 System Design Constraints Minimum SPL of 105 db at back row of (main floor) seating No more than ±5 db variation in SPL over the entire seating space for the 500 Hz, 1 KHz, 2 KHz, 4 KHz, and 8 KHz frequency bands Well aimed main arrays Fronts used to compensate front rows Delays used to compensate back rows Proper amplification to all speakers/parts of arrays $500,000 budget With a large budget like this, we can focus our attention on high end equipment

6 Loudspeaker Selection/ Placement/ Rigging

7 Info about Meyer Sound products for EASE

8 EASE Simulation Results 500 Hz Freq: 500 Hz Max SPL: = db Min SPL: = db

9 Freq: 1 khz Max SPL: = db Min SPL: =112.1 db EASE Simulation Results 1 khz

10 Freq: 2 khz Max SPL: = db Min SPL: =108.2 db EASE Simulation Results 2kHz

11 Freq: 4 khz Max SPL: = db Min SPL: = db EASE Simulation Results 4 khz

12 Freq: 8 khz Max SPL: = db Min SPL: = db EASE Simulation Results 8kHz

13 %ALCONS Max: 3.04% Min: 2.41% Ease Simulation Results %ALCONS

14 Loudspeaker Selection, Main x 40 We chose the Meyer Sound Milo for our mains and Main delays. this was chosen over the JBL VRX 932LAP because they have a better response, more powerful and have a wider coverage ($3,000) Acoustics Amplifier:

15 Loudspeaker Selection, Front Fills x 5 Meyer Sound UPM-1P ($1,300) Acoustics Amplifier

16 Loudspeaker Selection, Delays for Balconies/Under Balcony x 18 Meyer Sound UPA-1P ($2,000) Acoustics Amplifier

17 Rack Requirements and Design 3 Mid Atlantic MFR GE For FOH, Stage Left and Stage Right. T 1 Mid Atlantic MFR 2027 KM

18 Rack Requirements and Design - Power Distribution Power Distribution Speakers and Equipment - One for Stage Left and One for Stage Right - -Motion Lab Amp Three Phase l6-20 Distro

19 Power Amplifier Requirements and Selection/Signal Processing Requirements and Selection All Speakers are active and have a built in amplifier Meyer UPA-1P (Delay/Balcony Speakers) X 18 = 9,900 Watts 550 Watt Total for Output Power Two Channel complementary MOSFET output stages (Class AB/bridged) Max Peak Current, V AC/ V AC Meyer UPM-1P (Front Fills) X 5 = 1,750 Watts 350 Watt total for output power Complementary power MOSFET output stages (class AB/H) Maximum Peak Current, 1.3 V AC/ 0.65 V AC Milo (Mains) 3935 Watt Total for Output Power Complementary power MOSFET output stages (class AB/H) Maximum Peak Current, V AC / V AC

20 Mixing Console Looked at Digico D5, Avid S6l, and Midas ProX. We Chose this board because of its price an It also can be used for a variety of different shows with easy setup. YAMAHA CL5 W/ 2 Rio and 1 Rio 1608 Rack Digital Console with Automated Faders 72 Mono Inputs 24 Monitor Mixes Playback and Recording Capabilities through Dante Wireless Mixing from Ipad or Computer Capability of Storing 300 Scenes Dante Rio Racks for Easy Setup

21 Processing Galileo 616 Processor MEYER GALILEO 616 Processor 6 inputs, analog or Digital 16 analog Outputs Full 6 x 16 Summing matrix 24-bit resolution, 96 khz sample rate Input Processing - Gain,Delay, Trushping eq, 5-band parametric filtering, 31 - Band graphic eq Output Processing -Gain, Delay, Polarity Reversal, tru Shaping Equalization, 10 -Band parametric filtering, atmospheric correction, M Series array correction, Low - and High - pass Filters

22 Microphone Requirements and Selection Vocal Microphones Compared Shure KSM8 and Sennheiser e965 Both dual diaphragm condenser microphones Purchased 20 of the Sennheiser microphones due to better high frequency response and flexibility of cardioid / super-cardioid pickup pattern switch 20 SKP 2000 plug on transmitters with EM300 G3 rack mounted receivers.

23 Microphone Requirements and Selection Instrument Microphones 20 phantom powered Shure SM 137 instrument microphones good for drums and acoustic instruments In ear monitor system: 8 Shure PSM 900 systems Shure P9RA Wireless bodypack receiver Shure P9T wireless transmitter Drama / presentations Considered Shure Countryman B2D and Sennheiser EM 122 G3 system (includes bodypack, receiver, and lapel mic) Decided to buy 20 of the Sennheiser systems
