Microphone selection, placement, and setup
Teamline 5250 systems can provide phantom power through XLR connectors
used by active microphones, such as the StarLeaf microphone. The phantom
power supply can be enabled or disabled for each XLR connector using the
Maestro management platform. For more information about configuring
audio in Maestro, see
Configuring audio settings in Managing the room .
It is compatible with active microphones, which are designed for 48V
phantom power.
The specifications of the power supply are:
n
Output voltage when operational, no load: 45.3V +/- 4%
n
Output voltage when muted, no load: 35.3V +/- 4%
n
Power output source impedance: 1.97/- 2%
The StarLeaf microphone effectively picks up participants of all volumes
within a radius of 1.5m (4ft) centered on the microphone:
The effective pickup area of the microphone should be considered with the
dimensions of the conference table in the meeting room to decide on the
correct audio products for this environment.
Up to two microphones are supported for the Teamline 5250 system. If two
microphones are used, position them so that the distance between all
participants and the closest microphone is minimized. For instance, on a
circular table place the microphone in the center of the table. On a large
rectangular table measuring 3.6m x 1.2m (12ft x 4ft), place the microphones
1.2m (4ft) apart, 1.2m (4ft) from the ends of the table.
The input sensitivity of the XLR connectors is correct for all StarLeaf
microphones, by default.
