Converge/Converge Pro devices are designed to implement automatic microphone mixing, which increases audio
intelligibility by reducing reverberation and noise. Converge Pro implements its mixing function completely in the digital
domain, which greatly increases auto mixing precision. All audio is routed through the Converge Pro (both microphone
and speaker audio), which means the Converge Pro can more accurately make microphone activation decisions.

for example, when PA Adaptive is enabled, audio from another source (such as conference audio from another room)
is amplified through the speakers in the room. Typically, an automixer would activate at least one microphone, as if that
audio were a voice in the room. This false activation will not occur with Converge Pro (see figure 5.2) because the unit
can identify loudspeaker audio.

Converge Pro devices have a variety of automixing functions that are implemented on a per-channel basis and across
the entire auto mixer. These functions are described on the following pages. each Converge Pro device can have up to
four separate automatic mixers working independently, and up to four independent global mixers across multiple units.
In addition, more microphone channels can be added by linking Converge Pro units together to create a unified system.

Chairman Override
•
. This provides gating priority for all microphones selected for the chairman override group.
When a mic in this group gates on, all microphones within this group that are not chairman override enabled gate
off.
PA Adaptive (On or Off)
•
. PA Adaptive prevents the speakers from gating the mics on. Converge Pro can
accurately determine when loudspeaker audio is present because it samples the signal a few milliseconds before
it reaches the microphone.

. This mode allows you to program how many microphones
(maximum) can be gated on simultaneously. Generally, there isn’t a need for more than two or three people to
