5. Audio frequency response: +/—1 dB 50 Hz to 15 kHz control equalizer set flat and room equalizers switched out—microphone input to amplifier output. Measure with RTA.
6. Polarity: All microphones and source equipment must be wired in absolute polarity with the loudspeaker systems. Measure with a polarity checker.
7. Synchronize delay and fill systems to within 15 milliseconds of the primary loudspeaker system's first arrival as measured on Smaart or TEF measurement systems.
8. Acoustic coverage: Maximum +/- 3 dB SPL variance front to rear / side-to-side in the audience area through the 4 kHz full octave band. Measure with octave band Sound Level
Meter.
9. Acoustic amplitude response: With the room and equalizers switched in +/—3 dB, the maximum deviation from the following curve averaged from three test positions in the audience area flat at 60 Hz to 2 kHz, 10 dB at 50 Hz, and 12 kHz. Measure with RTA.
10. Electroacoustic gain: No less than 15 dB from 500 Hz to 4 kHz with one microphone and
12-inch source to microphone distance. Gain is to be measured 50 feet from the source.

2.11 SYSTEM ACCEPTANCE TESTS
A. System acceptance tests shall not be performed until the AV Systems Contractor Checkout has been completed and the test results have been reviewed. The System Acceptance Test will be supervised by the consultant and will consist of the following:
1. A physical inventory of all equipment on-site will be taken and compared to the equipment list in the contract documents.
2. The operation of all system equipment shall be demonstrated by the AV Systems
Contractor.
3. The AV Systems Contractor shall provide the necessary equipment for the Consultant to perform the AV tests.
4. The AV System Contractor shall have the latest as-built drawings, equipment inventory list, and manuals on-site and available. One set of these documents must have been sent to the
Consultant prior to the Acceptance Test.
B. Additional work by Consultant:
1. In the event of defective equipment or other adjustments that need to be made, the test may be postponed or continued later at the consultant's option.
2. However, if there is a return trip necessary by the consultant and/or a member of the consultant’s team as a result of improper installation or a failed system for performance standards, the consultant may charge the AV System Contractor directly or be deducted directly from payments (or the final payment) to the contractor. Hourly rates for the
Consultant and various team members are as follows:
a. Consultant $125
b. Project Engineer $95
c. Programmer $110
d. Network Engineer $125
3. Additional travel expenses, such as a rental car or mileage, will be charged as a cost plus a
