Enabling Telepresence
You can configure a LifeSize system for use in telepresence rooms in which a conference administrator controls calls from a control panel (such as LifeSize Control or the Call
Manager in the web administration interface) and users interact with the system using an attached phone.
Enabling telepresence removes the user interface from view. When the system is idle, only the background image appears in the display. An administrator can access the user interface by pressing OK and entering the administrator password.
During a call, users see the video from the call and the mute indicators. The navigation bar,
PIP windows, caller ID information, and call status messages do not appear on the screen.
Users can invoke the Call Manager dialog and call statistics and choose video inputs with the remote control. The numeric keys on the remote control play touch tones. Users can change this behavior from the Call Manager.
To enable or disable telepresence and lock or unlock cameras, configure preferences in
Administrator Preferences : Telepresence.
Configuring Audio Behaviors
You can adjust audio behaviors by configuring preferences in Administrator Preferences :
Audio.
Configuring Audio Codec Order
To change the order of available audio codecs for the system to use to place calls, select the
Audio Codec Order preference, select a codec, and press the right arrow to move the entry up in the list or press the left arrow to move the entry down in the list.
Selecting the Active Microphone
LifeSize video communications systems can connect to more than one microphone device for audio input during calls (for example, a LifeSize Phone, LifeSize Focus, and on codecs with a microphone in connector, a LifeSize MicPod). Only one of these devices can function as the active microphone during a call.

The Microphone In (no AEC) and Line In (no AEC) options are for connecting microphones that have their own acoustic echo canceller.
Camera options are for specifying LifeSize Focus as the active microphone.
When the Active Microphone preference is set to Auto (the default), or if the option selected is not connected to the codec, the system automatically attempts to select a device based on the following priority order:
LifeSize Model Default Order for Active Microphone Selection
LifeSize Room (codecs without a microphone in connector)

When the Active Microphone preference is set to Auto the following conditions apply:
• A LifeSize system ignores audio input from a LifeSize MicPod connected to the microphone input if a LifeSize Phone is also connected to the system. The
LifeSize Phone becomes the active microphone and the LEDs on the LifeSize MicPod flash red to indicate an invalid configuration. To stop the LEDs from flashing red, either disconnect the LifeSize MicPod or enable audio input from the LifeSize MicPod by setting Administrator Preferences : Audio : Active Microphone to Microphone In.
• The system does not automatically choose Line In.
LifeSize Video Communications Systems Administrator Guide 37
Adjusting the Active Microphone Volume
You can adjust the audio level for the active microphone by selecting Active Microphone
Volume and pressing OK on the LifeSize remote control.
Note: If you choose LifeSize Phone as the active microphone, the Active Microphone
Volume preference is not available. The LifeSize Phone microphones adjust volume automatically.
An audio meter appears below Active Microphone Volume when you access the preference. The audio meter shows the level of the transmitted voice in decibels (dB) root mean square (RMS) below digital full scale (DFS). The meter is accurate to ± 1 dB. The maximum level is 0 dB. Levels below –50 dB are not displayed, and indicate a very quiet or inactive input. Typical levels during a call peak around –28 to –22 dB DFS. A detailed explanation of how the audio meter functions on a LifeSize system and recommended settings for the Active Microphone Volume preference appear in the installation guide for your LifeSize system model.
Checking Microphone Status in the System Information Page
The Active Microphone field in the System Information page shows which device is functioning as the active microphone. When the value is None, the No Active Microphone indicator appears in the status bar of the user interface indicating that no active microphone is available.
Note: If you choose a line in option as the active microphone, and a device is not connected to line in on the codec, the No Active Microphone indicator does not appear in the user interface and the System Information page shows line in as the status for Active Microphone.
The Microphone In field appears in the System Information page for systems that have a microphone in connector on the codec and indicates the connection status of a device for the input (None, Ready, or Error).
38 LifeSize Video Communications Systems Administrator Guide
Configuring Audio In (Line In)
A LifeSize system automatically sends audio from a device connected to line in on the codec to line out, except when line in is selected for the Active Microphone preference. Line in is mono when selected as the active microphone for the Active Microphone preference.
Users and administrators can set the volume of line in using the Line In Volume preference in User Preferences or Administrator Preferences : Audio.
Note: The Line In Volume preference is not available for selection if the Active
Microphone preference is set to a line in option.
Two line in connectors are available on LifeSize Room 200, LifeSize Room 220,
LifeSize Team 200, and LifeSize Team 220. Use the Line In 1 Association and Line In 2
Association preferences in Administrator Preferences : Audio to select the video input to associate with these inputs. If you choose Any Input, the device attached to the line input is always audible. If you choose a specific video input from the preference options, the device attached to the line input is only audible when the video image from the selected video input appears in the display. If you select line in as the active microphone, its associated video input is automatically set to Any Input and you must use the Active Microphone Volume preference to adjust the volume for the line input.
Testing Primary Audio Output
You can send an audio test tone to speakers that are connected to the codec as the primary audio output device. Navigate to Administrator Preferences : Audio : Primary Audio
Output Test. Select a channel to test, or select Auto. The Auto option cycles through all available channels, playing the test tone for 5 seconds before moving to the next available channel. To end the test, choose Off or navigate to another preference or screen.
Note: The Test Center option is available on LifeSize Room only.
On LifeSize Room, and LifeSize Team MP, primary audio test tones output through line out only. On LifeSize Express series models, LifeSize Room 200, LifeSize Room 220,
LifeSize Team 200, and LifeSize Team 220, primary audio test tones output through line out and HD video out of Display 1.
Testing Auxiliary Audio Output (LifeSize Room Only)
You can send audio test tones to speakers that are connected to the auxiliary audio outputs on a LifeSize Room codec. Navigate to Administrator Preferences : Audio : Auxiliary
Audio Output Test. Select a channel to test, or select Auto. The Auto option cycles through all available channels, playing the test tone for 5 seconds before moving to the next available channel. To end the test, choose Off or navigate to another preference or screen.
LifeSize Video Communications Systems Administrator Guide 39
Muting Audio Inputs
By default, when you press the mute button on the remote control or on a LifeSize audio input device, all audio inputs to the system are muted, including audio from the active microphone, a PC connected to the codec for a presentation, or a device connected to auxiliary inputs if available on the codec. You can configure the system to mute only the active microphone by selecting Active Microphone Only for the Audio Mute preference in
Administrator Preferences : Audio. The default is All Inputs. Users can discover which option is selected for this preference by viewing the Audio Mute field in the System
Information page.
Selecting Audio Output
By default, audio in a voice call is sent to the LifeSize Phone attached to the LifeSize codec.
If you want the audio in a voice call to be sent to the line out, set the preference in
Administrator Preferences : Audio : Voice Call Audio Output. If LifeSize Phone is not connected to the LifeSize codec, audio in a voice call is sent to the line out regardless of the preference selected.
By default, audio in a video call is sent to the line out (typically, your display). If you want audio in a video call to be sent to the attached phone, set the preference in Administrator
Preferences : Audio : Video Call Audio Output.
Adjusting Audio Levels
In addition to adjusting the audio volume for line in and the active microphone, you can adjust levels associated with the following preferences:
• Auxiliary Audio Input Volume (LifeSize Room only)—Select the volume level for the audio sent through the auxiliary line input.
Note: If you do not hear the audio when adjusting the audio volume for a device connected to the auxiliary audio input, do the following:
1. Navigate to Administrator Preferences : Audio. Note the option selected for the Auxiliary Audio Input Association preference.
2. To hear audio from the auxiliary audio input, choose Any Input for the
Auxiliary Audio Input Association preference.
3. Use the Auxiliary Audio Input Volume preference to adjust the volume.
4. Set Auxiliary Audio Input Association to the option that you noted in
step 1.
