MIC SETTINGS - INTERACT PRO
The Mic Settings window is used to customize and configure the audio from the various
microphones that are connected to a Mic Input.
l Users can change the input label by clicking the text box next to the desired input label (for
example: Input2). Replace the default label with a new name for the input.
Level Tab
l Connected To: Shows make and model of pre-configured device dropped on channel, if
one was used
l Coarse Gain: Use the slider to adjust Coarse Gain for each of the 8 Mic Inputs inde-
pendently
l Fine Gain: Use the slider to adjust Fine Gain for each Mic Input independently
l Level Meter: Displays current Post Gain levels for each Mic Input
l ALC: Click the ALC button to activate Auto Level Control for each Mic Input independently
l Mute: Click Mute to mute each input independently
l P Pwr: Click the P Pwr(on by default) button to activate/deactivate phantom power on each
Mic Input independently
Processing Tab
l System Settings: AEC requires a physical output reference to track output gain changes.
Therefore when using virtual AEC references, you must use output gain tracking to provide
level information to the AEC process. Choose the appropriate output or outputs for the AEC
to track gain changes on when using the Virtual Reference(s).
l If you are using Mono mode, only one AEC reference is used. If you are using Stereo
Mode, both AEC references are used.
Note: Only use stereo mode if using true left and right channels.
l AEC: Click the AEC button (on by default) to toggle Acoustic Echo Cancellation on and off.
The radio buttons below set the strength of the NLP (Non-Linear Processing) setting.
o
NLP: Default is Soft. Click a radio button to set the Non-Linear Processing level or
deactivate the feature. Setting the NLP to higher levels may affect the full duplex
capabilities of your conferencing system.
l NC: Click the NC button (on by default) to toggle Noise Cancellation on and off, use the
slider to adjust Cancellation Depth. Use the lowest amount of depth as possible for best
audio performance.
l Enable PTT: Check the PTT box to enable Push-to-Talk. To set up PTT you must activate
the Pre gain meter by selecting the check box. Muting your PTT microphone at the micro-
phone element. Watch the Pre gain meter for the highest level, this is the electronic noise of
you PTT Microphone connecting. Set the PTT threshold to this level. Now when the PTT micro-
phone is muted and the pre gain meter reaches the set level, the microphone channels AEC
will freeze adaption and stop any echo artifacts from being transmitted to the far end of the
conference.
