Other Required Connections

• The unit requires access to a SMTP server for send-

ing error notiﬁcation emails. Do not allow email

replies to the unit.

• The unit requires access to an SNTP server for

obtaining an NTP time stamp. The unit sends its

SNTP request to “pool.ntp.org”.

• If software updates are to be performed,

the computer running the Qt PRO™ System

Monitoring and Control application requires

TFTP access to the unit.

Managing multiple control modules

• Browser “bookmarks” are a convenient tool for

managing multiple Qt PRO™ control modules.

Consider using a bookmark add-on that stores your

bookmarks on a web server for access to them from

any computer.

• Create a “Sound Masking” folder under Bookmarks.

Add a bookmark to each unit. Give them location-

based names. When you need to access a Qt PRO™

unit, open Bookmarks > Sound Masking and select

the target unit’s bookmark.

• Qt PRO™’s system overview page (big.htm) is

designed to be legible as the display page of a

thumbnail bookmark. By bookmarking each unit’s

main page using thumbnail bookmarks, the status of

the entire Qt PRO™ installation can be viewed from

a single screen.

ADJUSTING SOUND LEVELS

System volumes may be adjusted using either the front

panel controls or the software interface.

Masking Volume Adjustment

Important information about sound masking: It is es-

sential that the unit’s masking volumes be set

correctly, for each zone, to obtain the full effectiveness

of the system. If volumes are set too low, speech

privacy will be reduced and workplace distractions will

be more apparent. If volumes are set too high, the

masking sound itself may become a source of

distraction. Acoustic privacy increases as sound

masking volume increases, so the ideal level is one

that is high enough to be effective but not so high

as to be distracting.
