2. Cables dressed, routed, and labeled, connected with proper polarity.
3. Insulation and shrink tubing in place
4. Dust, debris, solder splatter, etc. removed
5. Proper frequency settings (or modules) at crossovers and controllers.
6. All equalizer bands and tone controls set for flat frequency response.
7. Test Instruments - Perform measurements using professional quality test equipment.
Acoustical measurement equipment shall be ANSI Standard Type 1 or IEC Precision Sound
Level Meter set for "slow" meter damping and flat response (unless otherwise indicated).
Light measuring equipment shall meet ANSI standards for measuring foot-candles.
C. Test Instruments - Perform measurements using professional quality test equipment. Acoustical
measurement equipment shall be ANSI Standard Type 1 or IEC Precision Sound Level Meter set
for "slow" meter damping and flat response (unless otherwise indicated). Light measuring
equipment shall meet ANSI standards for measuring foot-candles.
D. System Grounding Tests — While all sound/AV system power panel circuit breakers are turned off,
coordinate with Electrical Contractor to temporarily lift incoming main ground conductor from
ground bus in sound/AV system power panel. Measure and record DC resistance between the
power panel ground bus (now floating) and the disconnected feed from main ground. Resistance
should be greater than 1000 ohms. If less than 1000 ohms, determine the electrical paths between
system ground and power panel ground causing such readings, and report findings.
E. Color Bar Adjustments — Adjust color of all projectors, monitors, and plasma displays for
consistent color representation using color bar displays generated from projector and/or display
internal generators or contractor-provided portable generator. Adjust under ambient lighting
conditions anticipated for user of room.
F. Electrical Power Quality - While all sound and audio visual system components are unplugged from
electrical power outlets, turn on power to outlets, and confirm proper voltages at each outlet across
the following pairs of terminals: hot and neutral, hot and ground, and neutral and ground (zero volts
across neutral and ground). Document measurements.
G. General Function Tests - Test each piece of equipment to ensure that it performs its intended
function. Include all portable equipment in tests. Intent of initial tests is to verify complete,
functioning system before Final Tests and Adjustments. Correct problems found during initial
testing before beginning Final
Tests and Adjustments. Document whether all pieces performed intended functions; note any
unresolved malfunctions.
H. Initial Tests and Adjustments Data - Submit written report of Initial Tests and Adjustments data
upon completion of initial tests. Include printed name(s) of technician(s) performing tests, date(s)
and time(s) of tests, model and serial numbers of test equipment, results of each initial test,
descriptions of problems encountered and their solutions, and statement that system is ready for
Final Tests and Adjustments. Initial Tests and Adjustments Data to include signatures of
technician(s) performing tests.
I. Timetable
1. Submit report of Initial Tests and Adjustments data within 2 days of completion of initial tests.
2. Allow minimum of 3 days for review. If resubmittal is required, Owner shall be reimbursed by
Contractor for expenses incurred.
3.3 FINAL TESTS AND ADJUSTMENTS
A. Purpose — These tests are to be witnessed by Acoustical Consultant to determine if system is
complete and functioning as designed. Also, Acoustical Consultant will perform listening and
viewing tests and witness adjustments of all images for optimum clarity.
B. Timetable - Coordinate with Owner, General Contractor, and Acoustical Consultant to schedule
Final Tests and Adjustments after submittal of Initial Tests and Adjustments data.
C. System and Site Conditions — Acoustical Consultant (as Owner's representative) will witness
Final Tests and Adjustments. Have systems fully functional and ready for inspection and testing
