1.6.2 Locating and arranging the 7000 test system
Locate the 7000 test system in a moderately quiet area, such as a private office
or laboratory. In order for test results to reliably conform to specifications, the
ambient noise, mechanical vibrations, electrical or magnetic fields must not
affect test results by more than 0.5 dB (ANSI S3.22). Low-noise acoustic condi-
tions, as found in sound treated rooms and booths, are recommended but not
necessary.
Locate the main module near the sound chamber. The video monitor may be
placed on top of the main module.
If your 7000 has the Real-ear Option, further consideration needs to be given
to the placement of the sound field speaker. The speaker should be placed in
a manner in which the sound will not reflect off walls, chairs, tables, or other
objects. Such sound reflections could negatively affect test results.
1.6.3 Connecting the Main Module & Components
Connect the main module to the system components as follows (see Figure
1.6.3):
1. Connect the video monitor to the jack marked “Monitor” on the back of the
main module. Tighten the screws on the connector to secure the connection.
2. Plug the M1950E microphone into the connector marked “Microphone”
located on the back of the main module.
3. Connect the sound chamber cable into the plug marked “sound chamber” on
the back of the main module. Plug the other end of the cable into the sound
chamber. This cable provides all the connections necessary for operating the
internal loudspeaker, telecoil, and battery voltage supply of the 7020 test
chamber. Tighten the screws of the plug at each end of the cable to secure
the connection.
4. Plug the power cord into the three-pronged jack on the rear panel of the
main module. Plug the power cords of both the main module and the video
monitor into an AC outlet. We recommend using a switchable multiple out-
let power strip. Any voltage between 100 and 240 VAC is acceptable, 50 or
60 Hz line frequency.
