If installation occurs before the ofce is occupied, turn the system to

the desired level and leave it at that level. If the system is installed

after the ofce is occupied, turn the system to the correct level when

the space is unoccupied and employ auto ramping, only supported

through the MCS, to provide for a period of acclimatization.

To set the masking level for a zone, use the arrow keys on the front

panel to move to the right until the zone of interest is shown (Z1 is

zone 1 which matches the rst column of ports on the back). Then use

the up and down arrows to change the value.

After setting the value for one zone, arrow to the right or left to

set the value for zone of interest. Repeat for all zones. If a portion

of a zone is louder than the rest of the zone due to a difference in

acoustics, it should either be a different zone of the volume lowered

using the adjustment on the back of the emitters. The volume will still

change based on the value of the controller, but the output can be

turned down 3,6 or 9 dB from the value set at the controller.

IMPORTANT:

For full system effectiveness, it is essential to set the volumes

correctly for each zone.

If the volume is set too low, speech privacy is reduced and workplace

distractions are more apparent.

If too high, the masking sound can become a distraction. Since,

in general, acoustic privacy improves as sound masking volume

increases, the general strategy is to set the masking volumes as high

as possible without being distracting.

NOTE: If making adjustments from the front panel, do not disconnect

power for 10 minutes after setting values, or data may be lost. If

adjustments are being made via the web interface, there is no need

to wait.
