5.1 Connecting the speech source
5.1.1 Connecting a CD-player
To conduct speech tests using speech test
material you can connect a CD-player to the
MA 53. Use a standard phono plug cable to
connect the right and left outputs of the
device with the corresponding inputs

and

on the rear panel of the MA 53. To avoid
pinching the cables when closing the cover,
lay the cables in the slots provided.
If you are using a small portable CD-player
or tape you can place it on top of the cover
of the MA 53. This saves space and makes the usage of the CD-player or tape
very convenient.
Caution: If you are using a CD- or tape-player powered by electrical current,
the player must meet electrical safety requirements, such as IEC 601-1 or UL.
This is to avoid electrical shock of either the patient or you. If you are not sure
if your player meets these requirements it is safer to use battery power.

MIC connector

53. The microphone can be used for live
speech audiometry and communication
