Select Line Level to use the signal as it comes to the controller and

adjust volume from the zone window. Use Boost to add 10 dB to

the signal and then continue the adjustment of volume in the zone

window.

Time of Day Masking

QtPro allows the specication of a max time masking volume and

a min time masking volume for each zone. This allows complete

exibility to when the masking level needs to be high or low. Use the

pull down menus to specify each start time and the ramping interval

- the period of time allotted to accomplish the full, linear (in 0.5 dB

increments) transition. QtPro also allows you to specify Saturday

and Sunday operation. You can chose weekday operation (max/min)

or min operation where the min volume is in effect for the entire

(weekend) day.

QtPro obtains the time-of-day from either an Internet-based NTP time

server (pool.ntp.org) using the SNTP protocol or from its onboard real

time clock. QtPro requires the user to dene the time zone in which

the box is operating and the daylight savings time rules for that time

zone. If you are unfamiliar with your time zone, or daylight savings

time rules, a quick search on the Internet should help you nd this

information. Go to “Administration: Time Zone” to specify the control

module’s time zone and daylight savings time rules.

NOTE: NTP timer servers do not provide time zone or daylight

savings time rules and therefore these values MUST be specied by

the administrator.
