QSC System for a new Mad Mex restaurant.

I've just completed a design for a sound distribution system that will be installed in a newly constructed Mad Mex restaurant in Pittsburgh, PA. The foundation is built around the QSC Acoustic Design series of loudspeakers; specifically the AD-S282H dual 8" high powered cabinets. The expectation from the owner was that the sound be consistent throughout the space and perform well at volumes louder than the typical eatery. This system should accomplish that easily.



The main dining areas will be covered by 7 QSC AD-S282H dual 8" high powered loudspeakers, hung at 18' from the beams in the open space ceiling. The coverage pattern for these speakers is 90 degrees horizontal x 60 degrees vertical. The horns will be rotated on some of the cabinets in order to provide better coverage, based on the direction they will be mounted. These mains will also cover the small mezzanine section toward the back of the restaurant.

2 AD-S28Tw subwoofers will be mounted in the ceiling directly over top of the bar area, one facing the front of the restaurant and one facing the back. The speakers will be enclosed inside the overhang and ported with black mesh across the front of each opening. The architect included bass traps inside this area to help reduce unwanted reverberations. Mounted to the ceiling of the bar area will be 3 AD-S82H single 8" loudspeakers, arranged in a U-shape for the 3 active sides of the bar. This should help to fill in any gaps from the mains being blocked from the bar overhang.

Some AD-S52 s will be mounted in some private seating areas as well as a private room. The power will be provided by several QSC PLX3102 Powerlight amplifiers. The entire system will be controlled by the QSC DSP 322ua system processor. Some features of the 322 are:



Features:

• Universal inputs – mic/line with pre-amps and phantom power
• Configurable DSP functions and signal paths
• Fixed latency DSP engine
• Ethernet controllable

• Crossovers – Linkwitz-Riley, Butterworth, Bessel-Thomson in-phase, Bessel-Thomson symmetrical, 2-way, 3-way, and 4-way general purpose adjustable
• Compressors, peak limiters, AGC's, gates, dynamics processor
• Duckers – up to 8 channels, up to 60 seconds fade in and fade out times, priority mix
• Pink noise, white noise, sine generators
• Delays
• Macros – user-definable custom blocks with password protection 

As we progress through installation, I will update with pictures. Stayed tuned.

And remember:
If it can't be heard, it can't be Good!
