EXAMPLE (SEE THE ‘EXAMPLE’ FIGURE)
The first zone button (A ZONE) of all BM 3003 paging microphones is assigned to the
MASTER A output only.
The second zone button (B ZONE) of all BM 3003 paging microphones is assigned to the
MASTER B output only.
The third zone button (C ZONE) of all BM 3003 paging microphones is assigned to the
MASTER C, D and SLAVE A outputs.
AUTOMATIC LEVEL CONTROL (ALC)
This function automatically adjusts the level of one or more audio outputs according to
the detected ambient noise.
If ALC is enabled, the audio input no.8 is reserved for the microphone used as noise
detector and its red ALC indication lights up (below the signal level bar).
Note: set the input 8 to MIC and adjust its sensitivity according to the microphone type.
When the ambient noise (detected by the microphone linked to the input 8) is above the
threshold, all audio outputs keep their current level.
When the ambient noise is below the threshold, (only) audio outputs with ALC enabled
are processed (their level is attenuated).
Click ALC in the main window.
THRESHOLD : adjusts the level below which the ALC operates.
MIN GAIN : sets the minimum guaranteed level of audio outputs (with ALC
enabled) when the input no.8 microphone detects a noise level below the
threshold.
Attack
: adjusts the ALC attack time.
Release
: adjusts the ALC release time.
Ratio : signal slope in the range between MIN GAIN and THRESHOLD.
Enable : toggles the ALC (keep it on when using).
