These inputs can be configured in a matrix fashion to be directed to any processor output zone with individual level
control per zone at 1 db steps.
Note. Each zone on the QtPro control modules contains two physical runs. These runs are internally the same
zone and cannot be sent separate sources.
Contact Closures
The QtPro 300 and 600 series control modules have two contact closures. Contact closure A is a global mute and will
mute the sound masking signals during an emergency. Contact closure B mutes input B.
Input A is primarily the Paging Input and is not muted upon receipt of a contact closure, so paging signal important
messages are allowed to continue. Input B is generally the Music input and is muted by the contact closure B. The
sound masking signals are muted using on contact closure A during emergencies.
