Microphone placement for use with RoomTune

Note RoomTune requires the use of a RoomTune compatible talk-back microphone. Talk Back microphones pur-

chased before the release of OTOsuite version 4.75 are not compatible with RoomTune. The RoomTune com-
patible microphone can be recognized by the presence of a product label on the microphone cable.
Ideally, when you use RoomTune to tune speakers or view sound level measurements, the talk back microphone should
hang directly above the center of the client's head at a 90 degree angle to the sound source. Alternatively, someone sit-
ting in the client position can hold the microphone in front of their forehead. Make sure that the microphone is not in con-
tact with clothing, hair etc.
The microphone should be calibrated by an authorized service technician once a year.
