System commissioning with slow ramping is not possible
With traditional sound masking systems, a commission process is use that ramps up the sound masking
over several weeks' time. In the case of the Qt CRE system, because sound masking is user-initiated at
the time of using the conference room, no commissioning ramp is used. Note that commission ramp is
not possible from the Qt CRE calibration app, even though the option is resented as possible in the app
user interface.
