• If an error has been detected, the Error screen is
displayed. Click on + to acknowledge the error.
• If the unit has been configured for time-of-day
operation or if auto-ramping is on (in “Networked
Mode”) the masking volumes displayed are the
current volumes and the control panel warns the
user that time sensitive operations have been
configured. If this warning is presented, it is best
to change Qt PRO™’s masking volumes from a
browser. Changing any masking volume from the
control panel sets all zones to operate at their
“day” masking volumes, 24:7, overriding the
time-of-day function.
• Each volume parameter contributes from 1 to x
screens, where x equals the number of zones.
• Z1 means Zone 1, etc.
• Volume parameters set from the control panel are
operational 24/7. To configure time-of-day volume
features, the unit must be connected to a network
and accessed from a browser.
NETWORKED MODE - Recommended
(BROWSER-BASED CONTROL)
As a networked system, Qt PRO™ is controlled from
a browser (Mozilla 2.0+, I.E. 6.0+). The software
used to operate Qt PRO™, the “Qt PRO™ System
Monitoring and Control” application, ships pre-in-
stalled on the unit. Operating Qt PRO™ as a net-
worked system is as easy as attaching it to a LAN (10
Base T, IEEE 802.3 Ethernet), powering it on, and ad-
dressing it from a browser. For EMI suppression, attach
snap-on ferrite to LAN cable at point inside of box.
Several features are accessible only when Qt PRO™ is
accessed from a browser. These include auto ramping
of masking volumes, time-of-day masking volume con-
trol, email notification of system errors, and access to
Qt PRO™’s equalizers. Equalizers may be used by an
acoustics professional to obtain a preferred masking
spectrum, although the recommended spectrum ships
pre-installed on the unit. Equalizers are also provided
for paging and music. A special password is required
to modify Qt PRO™’s equalizers. If you are an acous-
tics professional, contact Cambridge Sound Manage-
ment for your unit’s “professional password.” You will
need to identify your unit to CSM via its MAC Address.
• Comprehensive operating instructions for net-
worked mode are embedded in the application
under “HELP”.
