3.3.2. Changing the input sensitivity and output volume by way of the control input or internal timer
Both the input sensitivity and output volume level can be changed between –21 dB and 0 dB.
Their increment or decrement level can be selected from 3, 6, 9, 12, 15, 18, or 21 dB.
Note
Both changes of the input sensitivity and output volume level are relative to the initially set levels.
The changed levels will not exceed the range from –21 dB to 0 dB.
[Change by means of the control inputs]
The input sensitivity or output volume level is continuously changed while the corresponding control input is
activated.
[Change by means of the internal timer]
The input sensitivity or output volume level is continuously changed during the duration from the start time to
the end time set by the internal timer.
[Setting example]
from 10:00 to 15:00, BGm is broadcast in the lobby at the volume higher than the initially set level.
The output level increment can be set for 3, 6, 9, 12, 15, 18, and 21 dB on a Pc.
