Device settings
Device settings
The StarLeaf portal allows configuration of Group Telepresence device settings.
To view device settings, login to the portal and view the meeting room page for the
Group Telepresence system. The device settings are in the section: Group Telepresence
device settings shown below:
XLR settings
The XLR settings are for each XLR connector on the rear of the Group Telepresence
system. For each XLR connector, you can alter the power and volume.
Phantom power is a way of providing power to a microphone. The StarLeaf GT Mini and
Group Telepresence 3351 both offer phantom power through each of its XLR connectors
for use by active microphones, such as the StarLeaf Microphone. The phantom power
supply can be enabled or disabled for each XLR connector, using the Group
Telepresence options in the StarLeaf Portal. It is compatible with active microphones
which are designed for 48V phantom power. The specifications of the power supply are:
StarLeaf Group Telepresence Installation Guide Page 13 of 27

Device settings
nOutput voltage when operational, no load: 45.3V +/- 4%
nOutput voltage when muted, no load: 35.3V +/- 4%
nPower output source impedance: 1.975kOhms +/- 2%
If you are using a third-party microphone, refer to your microphone's documentation to
discover whether or not you need to provide phantom power.
The volume setting adjusts the loudness of the people who are in the same room as the
microphone, as heard by the other participants in the call. For the volume, the
recommended setting is 0dB or 6dB. Only use 12dB in very large rooms or under guidance
from StarLeaf technical support.
The input sensitivity of the XLR connectors is, by default, correct for all StarLeaf
microphones and many 3rd-party microphones. If you need to alter the input sensitivity of
the XLR connectors, contact StarLeaf technical support.
If you need to alter the gain of the XLR connectors, contact StarLeaf Technical Support.
Line in
Use this setting to adjust the audio gain on the line in connector on the rear of the Group
Telepresence system.
Line out
Use this setting to adjust the audio gain on the line out from the Group Telepresence
system. This might be necessary to adjust the volume where you have connected external
speakers to the line out connectors.
Audio device selection for video calls
What you select is dependant on what you have connected to the line-in connector, as
follows:
nmicrophone source: if you connect a microphone source to the line-in connector, set
Audio device selection for video calls > Audio input to line in. In this case, the audio
from the microphone source will be sent to the far end and will not be played out
through the device selected in Audio output
nother audio: If you want to connect other audio devices to the line in connector (for
example a PC audio output), set Audio device selection for video calls > Audio input to
XLR (either one or both - as this is where you have connected the microphone). In this
case, the audio from the other audio device will be played out through the device
selected in Audio output and also sent to the far end
StarLeaf Group Telepresence Installation Guide Page 14 of 27

Device settings
Audio device selection for audio-only calls
These settings provide options for selecting the audio output in audio-only calls:
nuse StarLeaf Phone or Touch: in an audio-only call on the StarLeaf Phone, the sound will
emanate from the handset or headset of the phone unless someone has pressed the
speakerphone button on the phone, in which case the sound will emanate from the
phone's speaker. In an audio-only call on the StarLeaf Touch, the sound will emanate
from the speakerphone
nuse selection for video calls: the audio device selection in an audio-only call will be the
same as in a video call. That is, it will use the settings from Audio device selection for
video calls
Disable ECAN
This setting, when selected, disables echo cancellation. Do not disable ECAN unless you
have specific cause to do so. Only disable ECAN if you are using additional equipment to
suppress the loudspeaker signal on all microphone signals.
