Set a filter and output
Proceeds as follows to set the filters of each output separately.
1. Make sure that all loudspeakers are connected to each amplifier output, set at the
correct power level, are aimed (if necessary) and are working.
2. The frequencies, gain and quality factors of each output are already set to the default
values as indicated in the previous table:
– IMPORTANT: The correct output setting depends on the environment to where the
audio output signal is routed to, and possible needs to be adjusted in the zone(s)
locally.
3. Enable (checkmark) the Active box of each filter for each output to enable it and to make
it active in the system.
4. Click the Apply button:
– Be aware that the changes are immediately applied to the audio output and could
cause unexpected high‑level audio output in the loudspeaker zone(s).
5. Click the Submit button to submit the changes.
– Notice that audio processing parameters are changed immediately when also the
Submit button is clicked. Although the changes are audible, it is important to realize
that they are not automatically saved. If the changes are not saved they will be lost
when the system controller resets. See
Save configuration, page 102
