PART 1 - GENERAL

1.1 BACKGROUND

The National Institutes of Health (NIH), a part of the U.S. Department of Health and Human Services, is the nation’s medical research agency – making important discoveries that improve health and save lives. NIH is made up of 27 Institutes and Centers, each with a specific research agenda. Among the 27 NIH Institutes and Centers, the National Institute of Allergy and Infectious Diseases (NIAID) conducts and supports basic and applied research to better understand, treat, and ultimately prevent infectious, immunologic, and allergic diseases.

The Office of Cyber Infrastructure and Computational Biology (OCICB) manages technologies supporting NIAID biomedical research programs. The office provides a spectrum of management, technologies development, applications/software engineering, bioinformatics support, and professional development. OCICB works closely with NIAID intramural, extramural, and administrative staff to provide technical support, liaison, coordination, and consultation on a wide variety of ventures. These projects and initiatives are aimed at ensuring ever-increasing interchange and dissemination of scientific information within the federal government and among the worldwide scientific network of biomedical researchers.

The NIAID has approved the upgrade and renovation of Microphones for seventeen (17) Resource Libraries for use with the audio and video teleconferencing rooms, located at 5601 Fishers Lane in Rockville, Maryland. Those rooms are as follows:

1F100 3F100 4F100 5F100 6F100 7F100 8F100 9F100 2C100 3C100 4C100 6C100 7C100 8C100 9C100 4H100 8H100

1.2 OBJECTIVE

The OCICB requires immediate assistance with the implementation of 3 ceiling mounted microphone arrays in each of the Resource Libraries as well as the associated equipment, cabling, and programming updates, which are required in order to integrate the new microphones and the control of the audio as required for them to operate in the conventional Video Conference and the PC based Lync conferencing capabilities. The existing table microphones, switches, logic boxes, and cables, will be removed and turned over to the owner. The holes were the microphones are currently located will be plugged with black grommets glued in place to minimize the chance of them being removed and lost.

6. All products are neat, clean, unmarred and securely fastened.

7. All debris has been cleaned and removed from the site.

8. All electronic devices are properly grounded.

B. System(s) Gain Adjustment:

1. Adjust each active device to have unity gain from the console output to the input of the amplifiers.

2. With all amplifiers turned off, connect a sine wave and pink noise to an input of the console. Using a RMS voltmeter, adjust the scale to an output between - 10 and 0dBu. Once level has been established, it should remain unchanged throughout the testing.

C. Amplifier Level Adjustment:

1. Adjust the gain of each amplifier to provide consistent and appropriate levels throughout the seating areas/facilities.

2. With the console and other electronic devices feeding the amplifiers adjusted as described above, adjust the output of the console to be -10dB on the output VU meter.

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

2. After initial amplifier adjustment, walk all areas utilizing the 70 volt systems and check for volume uniformity. If any changes of 3dB or more occur, adjust that specific area or speaker as required for even coverage.

E. Input Verification Test:

1. Using a microphone, portable signal generator, or CD player, send signal from every microphone input to the console. Check every connection location in the facility.

2. Verify video signal presence at each component input with test equipment and verify the proper signal and uniform strength.

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

4. In a similar manner, check any other inputs or tie lines, as appropriate.

0 dBu reading for the mixer or mixing console output. Distribute this output to all systems and subsystems.

4. Adjust the output of line level electronics and signal processors to obtain a 0 dBu output at the output terminals. For equipment with input level controls, adjust the input controls so that input levels peak at -10 dB. For equipment not capable of providing 0 dBu output, adjust to achieve as close to 0 dBu as possible.

4. Repeat this test for each mode of operation of the lighting dimmers (incandescent, neon, and fluorescent).

K. Background Noise:

1. Using a calibrated ANSI S1.4-1983 (1997) Type 1 or IEC 60651-01-1994, precision sound level meter, determine the average ambient noise level in the room. Record the level derived. The average background noise shall be 60 dBA or below during performance of the following tests. If noise level exceeds this criterion, promptly notify the Consultant before proceeding further.

2. Turn off systems except the speaker system under test.

3. Using pink noise as an input and with system equalizers set to bypass operation, determine the average frequency response of the loudspeaker system in the room using a 1/3 octave real time analyzer.

4. Record the frequency response derived.

5. Locate the analyzer microphone approximately 1 m above the floor at a point which approximates the average frequency response, within ±3 dB from 50 Hz to 16 kHz.

6. Record the frequency response at this location.

300 mm from the corresponding system microphone. Adjust the pink noise source to provide a level of 75 dBA at the microphone and set mixer levels to achieve a 0 dBu level at the mixer output.

b. For line level inputs: use system program source equipment, with pink noise playback media as a direct input to the mixer or mixing console and set mixer levels to achieve a 0 dBu level at the mixer output. Repeat for each system input individually where mixer inputs vary in input sensitivity.

Settings for equivalent sensitivity inputs may be duplicated.

c. With any input set as specified above, adjust audio distribution amplifiers to provide levels of -10 dBu at each output.
