NC Button, Clear Effect Button, ALC Button | ClearOne comm PRO 8I

The Receive Input meter displays the dB level of the incoming telco signal prior to any signal processing.

NOTE: All meters in Console are peak-level meters.

NC Button

Clicking the Noise Cancellation button opens the Channel Property Configuration: Telco RX window with the NC tab selected, allowing you to configure noise cancellation settings.

To use noise cancellation, click Enable Noise Canceller, then adjust the Cancellation Depth to the setting which provides the best combination of low noise and maximum speech clarity for your installation. The attenuation depth can be set in 1dB increments from 6dB to 15dB. The default is 6dB. The noise canceller default is Off.

Clear Effect Button

To reduce bandwidth requirements, telephone lines limit audio bandwidth to a range of 300Hz–3.3kHz. ClearEffect enhances the incoming signal from a telephone line to emulate wideband audio by adding high and low frequencies to the audio signal.

Click the ClearEffect button to toggle this feature on and off. The default is On.

ALC Button

Clicking the Automatic Level Control button toggles ALC on and off. ALC provides auto-leveling for all conference call participants on the telco rx line, keeping soft and loud participants at a consistent level. The default is Off. See AGC/ALC for additional information.

NOM Button

Maintains a constant output level by automatically adjusting gain levels based on the number of mics gated on and routed to the selected output channel. NOM reduces the output level proportionally by 3dB for every doubling in the number of open mics. When using NOM over the expansion bus, only I – R Buses support passing NOM information. The default is On.

Mute Button

Clicking the Mute button toggles muting for the telco receive channel. The default is Off.
