Direct audio input
Direct audio input (DAI)
is used when you want to
directly receive signals from
external sources e.g. radio, TV
and assistive listening devices.
The external sound source is
connected to your hearing
instrument via a cable and an
audio shoe which may be
obtained from your hearing
care professional.
With DAI you will hear the
audio signal and the ambient
sounds simultaneously when
the instrument is switched to
M. Switch to T if you want to
hear a pure audio signal.
