Connect a sound source to INPUT 1.
When INPUT 2 is used in the setting step below, also connect a sound source to INPUT 2.
3-1. Set the GATE LEVEL while monitoring the INPUT LEVEL
indicator.
Both the INPUT 1 and INPUT 2 are set to the same level.
When the input level is below the GATE LEVEL, the ALC level
is kept unchanged.
When it is above the GATE LEVEL, the ALC function works to
change the controlled variable.
3-2. Set the input sensitivity to +4, –8, or –20 dB depending on the
input level.
Both the INPUT 1 and INPUT 2 are set to the same level.
3-3. Adjust the BGM broadcast level.
Perform this step when the INPUT 1 is used for announcement
and the INPUT 2 is for BGM, and when BGM is desired to be
broadcast in smaller volume than announcement.
The BGM LEVEL to be set here is the attenuation level to the
announcement level.
For example, when BGM is broadcast 6 dB smaller than
announcement in volume, set the BGM LEVEL to –6 dB.
