Adapters

When connecting a patch cable to the Direct Connect system, an adapter may be
needed, depending on the output of the device to which you are connecting. There
are two main types of adapters: one for size and one for signal type.
Size adapters will allow you to connect a patch cable that does not physically fi t into
the 3.5 mm audio jack.
Signal adapters will convert the signal type to that used by the cochlear implant
system. There are two main signal types: mono and stereo. Connecting the incorrect
signal type can potentially degrade sound quality or even damage the external
audio device. The audio jack on the Direct Connect is designed for stereo input.
You can identify if a patch cable is intended for mono or stereo use by looking at the
number of black rings located on the plug. Mono is designated by having one black
ring whereas stereo has two black rings.

Personal FM Systems

An FM system is an assistive listening device to improve listening in noisy environments
and overcome problems of listening at a distance. FM systems have a microphone/
transmitter worn by the speaker and a frequency-tuned receiver worn by the
cochlear implant user. See the "Auria iConnect Adapter" section of this manual for
more information.
