Configure General Audio Settings

You can configure audio settings in the RealPresence Centro system web interface.

Some audio settings are unavailable when you connect a SoundStructure digital mixer to your system.

Procedure

  1. In the system web interface, go to Admin Settings > Audio/Video/Content > Audio.
  2. At General Audio Settings, configure the Audio settings described in the following table.

    Setting

    Description

    Sound Effects Volume

    Sets the volume level of the ringtone and user alert tones.

    Ringtone

    Specifies the ringtone for incoming calls.

    User Alert Tones

    Specifies the tone for user alerts.

    Audio Mute Auto-Answered Calls

    Specifies whether to automatically mute incoming calls.

    Note: You must first enable Auto Answer Point-to-Point Video or Auto Answer Multipoint Video in Call Settings to use this feature.

    Enable Keyboard Noise Reduction and Polycom NoiseBlock

    Specifies whether the system microphones mute when the system detects keyboard typing or other extraneous noises but no one is talking. NoiseBlock unmutes the system when it detects speech, regardless if there’s background noise or not.

    Note: M-Mode is disabled when you enable this setting. If you use an external echo canceller, keyboard noise reduction is not available.

    Transmission Audio Gain (dB)

    Specifies the audio level (in decibels) that the system transmits sound. Unless otherwise advised, Polycom recommends setting this value to 0 dB.

    Enable Audio Mute Reminder

    Specifies if the system displays a notification that the microphones are muted when it detects someone speaking.

    Enable Join and Leave Tones

    The system plays a tone when someone joins or leaves a conference call.

    Note: This setting is available only when you install the multipoint option key.

    Enable Acoustic Fence

    Specifies if the system uses Acoustic Fence technology.

    Acoustic Fence Sensitivity

    Specifies the microphone sensitivity for Acoustic Fence technology. You can set a value between 0 and 10, where 0 is the minimum sensitivity and 10 is the maximum sensitivity. Higher settings increase the radius of the fence area around the primary microphone.
