2 SYSTEM DESCRIPTION

1 The following is intended to provide an overview of the design concepts and is not an exhaustive description of the Systems. Generally, ceiling or surface speakers are specified depending on the ceiling type, room finish and reproduction quality requirements. Typically, provide surface mounted loudspeakers in rooms with no ceiling and recessed loudspeaker assemblies in areas with a finished ceiling.

2 Each reinforcement system is designed to provide high level, full range speech and music to all seats in the area. The system is designed to equal or exceed the sound quality of other contemporary similar facilities.

3 The speaker system should provide sound levels of at least 105 dBA (continuous) with a seat to seat variation in coverage of +/- 2.5 dBA or less.

4 The general loudspeaker configuration for each large open area is to have main full range and low frequency loudspeakers (also referred to as the MAIN loudspeaker system) supplemented with “fill” or “delay” speakers.

5 Power amplifiers and speaker signal processors will be centrally monitored in the Control Booth.

6 The Control Booth is located where floor microphone inlet and tielines terminate. Wireless microphone, local program sources, patch frames and a primary mixing console will be housed here. The amplifier and DSP control computer will also be located here. The control booth will distribute audio to each sound reinforced room in the facility as selected by hard patching or DSP control for those rooms. Input panels are located throughout the facility to permit connection of microphones, monitor speakers, intercom and other audio cables as required. These panels will also permit the use of microphones “snakes” with multiple outlets for special events.

7 All house mic lines will be routed in copper cabling to the Control Booth, where they terminate onto a patch frames.

8 Dedicated AV network switches and support equipment are supplied to assure reliable audio transmission. For longer transmission runs between audio devices, dedicated optical fibers are used to carry the digital audio. Shorter distances are managed by copper category rated cable.

9 As an aid to the emergency system, the loudspeakers will receive warning signals and announcements from the main fire command center. Tie lines to interface these systems will be the responsibility of the Contractor. During an emergency with the fire alarm, all systems other than those that cover the main bowl shall mute. A flashing indicator should warn the control booth operator that the Emergency system has taken control of the sound system.

10 Interview/Multi-purpose Room: A ceiling-mounted projector displays sources onto a large recessed ceiling-mounted screen. Sources available for display are: Bluray/DVD playback or sources connected to the rack-mounted input plate. The input plate contains connectivity for a laptop computer, or auxiliary video source with stereo audio. A wall-mounted control panel provides the touch screen interface for control of the in-room system components. The control system provides control of: transport controls of the Bluray/DVD player, Screen Up/Down, Video Projector On/Off, source selection and volume.

11 Conference Room: Conference rooms can be operated separately or if separated by a removable divider they can be operated together. In-room input plates are routed through a collective matrix switcher which allows the viewing of any input plate source onto any or all of the video projectors. Each conference room contains a BluRay/DVD playback unit. Either Blueray/DVD player can be viewed on any or all of the video projectors. Transport controls for the Bluray/DVD player will be via in-room control panel. Each Conference Room also contains a wall-mounted control panel. The control panel will contain a password protected page for the combining and uncombining of the rooms. The password protected page will prevent unauthorized or accidental sending of sources to adjacent rooms. The in-room control panel will also allow source section as well as microphone and program volume control. The control processor will control the DSP processor via the LAN.

5 Contractor commissioning

1 Prior to energizing or testing the system, ensure the following:

1 All product is installed in a proper and safe manner per the manufacturer's instructions.

2 Insulation and shrink tubing are present where required.

3 Dust, debris, solder splatter, etc. is removed.

4 Cable is dressed, routed, and labeled; connections are consistent with regard to polarity.

5 All labeling has been provided.

6 Temporary facilities and utilities have been properly disconnected, removed and disposed off-site.

7 All products are neat, clean and unmarred and parts securely attached.

8 All broken work, including glass, raised flooring and supports, ceiling tiles and supports, walls, doors, etc. have been replaced or properly repaired, and debris cleaned up and discarded.

9 Electronic devices are properly grounded.

2 Prior to energizing the system, perform the following tests in compliance with applicable EIA standards. Record the results of each test in the Project Record Manual.

1 Test each AC power receptacle with a circuit checker for proper hot, neutral and ground connections.

2 Measure and record the DC resistance between the technical ground in any equipment rack or console and the main building ground. Resistance should be 0.15 ohms or less.

3 Temporarily lift the technical ground from the main electrical ground, measure and record the DC resistance between them. Resistance should be 1000 ohms or greater.

4 Measure the impedance of each Loudspeaker line leaving the equipment racks. For full range devices, use a frequency of 1000 Hz and 1OOHz, for band limited devices, use a frequency appropriate for the operating range of the transducer. When documenting the results of these tests, include the calculated impedances based on number of units on a line and the size and distance of the run. Correct any field readings that differ more than 20% from the calculated impedances.

3 Loudspeaker Circuit Verification Test

1 Provide a low level, band limited test signal to each amplifier input.

2 Turn on one channel of Amplifier #1 and verify that the correct Loudspeaker or group of Loudspeaker is operating. Correct any wiring or other problems found.

3 In a similar manner, check each channel of all remaining amplifiers and their respective Loudspeaker circuits.

4 Include the results of the tests in the Project Record Manual. D. Constant Voltage Loudspeaker Test

1 Play music, pink noise or other distinctive audio signal through each group of constant voltage Loudspeaker. Only one amplifier channel should be on at a time.

2 Walk the area covered by the Loudspeaker.

3 Verify that each Loudspeaker is operating and that there are no significant changes in volume level from one Loudspeaker to the next.

4 Verify that the extent of coverage is consistent with the areas indicated on the drawings.

4 Loudspeaker Polarity Verification Test

1 Use an electronic polarity checker, TEF-20, SYSID, SIM II, or other similar device to test each reinforcement Loudspeaker. All Loudspeaker should have the same relative polarity.

2 Follow manufacturer's recommendations in conducting the tests.

3 In a similar manner, check all distributed Loudspeaker to ensure they have the same polarity.

4 Include the results of the tests in the Project Record Manual.

5 System Gain Adjustment

1 Adjust each active device for proper gain from the console output to the input of the amplifier.

2 Record the output levels of each device in the Project Record Manual.

6 Signal Delay Adjustment

1 Adjust the delay to each subsystem to ensure proper synchronization between the main Loudspeaker and delayed Loudspeaker.

2 Using a TEF 20, SYSID, Smaart, SIM II, or other acceptable time based measurement system, measure the arrival time of the distant signal and then measure the arrival of the local signal.

3 Based on the arrival times measured, adjust the delay applied to the local Loudspeaker to synchronize them with the distant Loudspeaker. Repeat the test to verify the delay has been set to within 1 ms of the arrival of the distant signal.

4 Continue to test and adjust each separate subsystem with a dedicated delay channel.

5 Provide hard-copy printout of each delay adjustment showing first the arrival times with no delay set and then the result after the delay has been adjusted. Record the settings of each delay in the Project Record Manual.

7 Level Adjustment- Main Reinforcement System

1 Adjust the gain of each amplifier to provide a consistent and appropriate volume level throughout the facility.

2 Begin by connecting a pink noise source to one input of the mixing console. Adjust the console output to -10 dB on the VU meter.

3 Adjust the appropriate amplifiers to achieve 85 dBA in the area covered by one section Loudspeaker. Use a calibrated sound level meter to make the measurement.

4 If the test group of Loudspeaker employs an active crossover, use a live IE-30, TEF 20, SYSID, Smart or SIM II to balance the spectrum by adjusting the amplifier for each band.

5 Once the initial Loudspeaker have been properly adjusted, begin adding the Loudspeaker in each adjacent areas and repeating the same adjustments.

6 When a given area or seating level has been completed, move to the next lower area and repeat the tests and adjustments for that area.

7 Amplifier settings for Loudspeaker covering similar seating areas should have the same gain settings. Investigate and correct any occurrences where an amplifier deviates more than 2 dB from the average.

8 Amplifiers should be set to provide an average of 85 dBA ±1.5 dB throughout each seating section.

9 Record the setting of each amplifier in the Project Record Manual and keep backup copies of the data file on disk.

8 Amplifier Level Adjustment- 70 Volt Systems

1 Adjust the level of 70 volt systems to achieve a volume level appropriate for their location and intended use.

2 After setting the amplifier level for each system, play a pink noise signal over the Loudspeaker and walk through each area. Using a sound level meter, identify any areas where the SPL changes by more than 3 dB. Identify the cause of the change and where it is due to mounting height or architectural differences, adjust the transformer taps of the affected Loudspeaker to bring the sound level within range. Include any changes on the Record Documents.

9 Headroom Verification Test

1 Once the preceding tests and adjustments have been completed, play a variety of musical programs through the system. Amplifiers should be off for this test.

2 Adjust the console gain to achieve peak output levels of +6 VU on the console meters.

3 Observe if any of the components indicate clipping or less than 3 dB of headroom.

4 Replace the musical program with a steady 1000Hz sine wave. Connect an oscilloscope or similar device to selected amplifiers in each portion of the reinforcement system.

5 Increase the output level of the console until the signal displayed on the oscilloscope begins to show distortion. Record the dB level of the signal from the console and which component in the chain is creating the distortion in the Project Record Manual.

10 Remote Input Verification Test

1 Using a microphone or portable signal generator, connect to each microphone receptacle throughout the facility.

2 Verify that the receptacle under test appears at the correct position on the patch bay and is operating properly.

3 In a similar manner, check all remote tielines and media related lines for correct wiring and labeling.
