CAUTION
Danger of hearing damage due to loud hissing!
When the floor channel volume is set to a high level or when several
participants speak simultaneously, feedback (loud hissing noise) can
occur. This can cause hearing damage.
왘
Reduce the floor channel volume (see below).
왘
Activate the “ Feedback Suppression ” function to be able to
increase the volume before feedback can occur (see page 24).
왘
Make sure that the “ Audio Gain Reduction ” function is activated
(see page 24). This function reduces the gain per active micro-
phone by the selected level and thus prevents feedback noise.
왘
Increase the distance between the individual conference units to
at least 50 cm.
왘
Turn the jog dial
– to the right to increase the volume or
– to the left to reduce the volume.
Use the “ Feedback Suppression ” function to be able to increase the floor
channel volume by up to 5 dB without feedback occurring (see page 24).
