Modes of operation

The Multi Mic is a versatile speech and audio streamer offering
both microphone pickup while worn vertically on the body, or as
a table microphone while placed horizontally on e.g. a table. It
also offers extended audio source connectivity options by being
able to receive telecoil signals, FM signals (optional FM receiver
needed) and connecting to auxiliary audio sources through the
built-in mini-jack line input. It is possible to stream speech and
audio in the following ways:

From the built-in microphones

In microphone mode the Multi Mic will send sound from
the environment to the hearing instruments. The Multi Mic
will optimize the speech pick-up depending on how it is
used. When wearing it vertically on the body (using the clip
or the lanyard) the Multi Mic will be in a mode, minimizing
background noise.

When placed horizontally on a table, the Multi Mic will
switch into an optimized Table mode, enabling pick-up of
speech from more speakers placed around the unit.

From the built-in Telecoil, receiving audio from a teleloop
system (available at e.g. some theatres, schools, churches,
etc.). Note: Telecoil mode will not be available when the
Multi Mic is charging.

22

400544000-GB-15.09-Rev.A.indd 22 11-11-2015 16:16:43

From an external, analogue audio source. In line-in mode
the Multi Mic can receive audio from an audio device such
as a mobile phone, MP3 player, tablet, computer or TV. To
use this mode, the audio device must be connected to the
Multi Mic using a mini-jack cable (included with the Multi
Mic). When an audio device is connected, line-in mode will
automatically be selected. Other modes can be selected
by clicking on the mode button until the desired mode is
reached. In this mode, the hearing aid user will wear the
Multi Mic or have it nearby.

From an external FM receiver. In FM mode the Multi Mic
can receive audio from a FM transmitter. This requires that
an FM receiver (optional accessory) is attached to the Multi
Mic via the 3-pin Euro pin connector. When the receiver is
inserted the FM mode will automatically be selected. Other
modes can be selected by clicking on the mode button
until the desired mode is reached. In this mode the hearing
aid user will wear the Multi Mic or have it nearby. The Multi
Mic will now be able to transmit the received FM signal to
the hearing instruments.

Note: Line-in and FM modes can only be selected if a cable

i

or an FM receiver is inserted into the Multi Mic.
