speak at the same time.
First mic Priority mode (On or Off) • . This feature increases the audio level required to gate on additional
microphones after the first mic gates on. This helps ensure that only one mic gates on when a person speaks.
Last mic On/mic1-8/Off • . last Mic On leaves the last activated mic on until a new one is activated. Mic 1–8 mode
reverts back to the mic you’ve selected for Mic 1–8 on when all other mics gate off. These features are useful to
ensure the audio never goes completely away. Without it, participants might think that you have lost connection to
the other room. You can set this parameter to Off.
The following are depicted in Figure 5.4 (below):
gate ratio Adjust (0 to 50db) • . This specifies how much louder the audio level must be above the ambient
level to gate on. for example, if the gate threshold is set at 35db, it will take 35db plus the gate ratio to activate
the microphone. The ambient audio level can be specified, or the adaptive ambient mode can be turned on. In
this case, as the ambient room level changes the audio level required to activate a microphone will also change,
preventing background noise from falsely gating on microphones.
Off Attenuation (0 to 50db) • . This sets how much a gated input is attenuated when it is not on.
Hold Time (.1 to 8.0 seconds) • . This sets the length of time the mic stays gated on after audio is no longer
present (keeps the mic from gating off to pauses in speaking).
Decay rate (slow, medium, fast) • . This sets how quickly the audio level attenuates to the Off Attenuation level
after the hold time has expired.
manual Ambient Level (0 to -80db) • . This setting is relevant only if the adaptive ambient mode is disabled on
the individual gated inputs. This ambient level is then used in conjunction with the gate threshold to determine
whether or not the mic should turn on.
