12. Configuring Informer15 and Informer100 PA (VoIP) Settings
The Informer15 and Informer100 devices have PA (VoIP) settings for sound power during
public address announcements. The power attenuation allows the sound output to be
attenuated up to 20 dB for PA. For example, if set to -10 dB the sound output of the
speaker will be lowered from the maximum by 10 dB. The maximum power attenuation
adjustment is 20 dB.
The Informer15 and Informer100 devices also have an ambient attenuation setting, which
allows automatic attenuation based on sound level at the Informer15 or Informer100. For
example, if the ambient attenuation is set for 70 dB, then for every dB the noise level
is below 70 dB (at the Informer), the Informer will attenuate the sound level output by a
decibel. The maximum power attenuation and ambient attenuation is a combined 20 dB.
Using Power/Ambient Attenuation Threshold
If using an Informer Speaker with PA (VoIP), select the PA (VoIP) setting:
• Power Attenuation—Set attenuation of output level during PA. You can use up to 20
dB of attenuation.
• Ambient Attenuation—Set level at which the speaker begins to add attenuation to
the output level. A maximum of 20 dB total attenuation is possible with Power and
Ambient settings.
For example:
If Power Attenuation is set to 5 dB and Ambient Attenuation is set to 50 dB, the
Maximum output is 109 dB; and if the noise level at the speaker is 40 dB, the sound
output is lowered to 99 dB.
Enter 0 if no automatic attenuation is desired.
•. Voice Under run delay—Use this feature to delay PA output.
• Relay x On—Use this feature to turn on a relay during PA.
