Switching between stereo and mono operation
With certain sound recordings, voice or audio signals are
recorded on one channel only (right or left stereo channel).
This can result in a loss of individually recorded voices or
instruments, especially when you have changed the balance
setting.
In order to avoid this effect, you can switch between stereo
and mono operation.
This setting is saved on the transmitter, independent of the
stethoset receiver you are using.
