Transducers
Figure 8 shows the three level combinations
for transducers. "Full Level" transducers are
recommended for solid or cement walls,
floors, and ceilings. "1/2 Levels" are used
for typical drywall or less dense surfaces.
"1/2 Levels" and "1/3 Levels" are suggested
for glass panes dependent on size.
Combining levels can be done, but care
should be taken to verify the correct output
volume out of each transducer.
Figure 8
Speakers
Figure 9 shows the three level combinations for the QMS-2000 speakers. "Full Level" is
recommended for large closets and large crawl spaces. "1/2 Level" is used for small crawl spaces,
closets, and ceilings with a large distance between the tile and ceiling. "1/3"Level" is suggested for
very small areas and ceilings with very little space between the tile and the top of the ceiling.
Similarly to the transducers, care should taken if the speaker levels are mixed to ensure that proper
volume is being achieved to all the speakers.
Figure 9
Note: Speakers can be added
until 8 ohms is reached. Control
of the level may become difficult
due to location of the speakers.
The user should use his or her
own judgment when connecting
speakers.
EXAMPLE
Figure 10 is an example diagram
of a typical office setting. The
target room is protected from
adjacent offices, inner building
walls, restroom/janitorial walls,
outside windows, and drop ceilings. The DNG-2300 is setup so that the wall surfaces are all on the
same channel. This allows the equalization of the noise for that particular surface material. The
windows and ceiling have been combined on one channel for simplicity. When combining different
surfaces on the same channel, walls should be kept separate from windows and ceilings.
