– Mono R: Only the right channel of the audio input will be encoded
– Mono (L+R)/2: If you have connected a Stereo signal this setting allows
the generation of a Mono signal.
• Stereo Mode: This option define the Stereo mode of the encoder. Three pos-
sibilities are available:
– Stereo: This mode is recommended for data rates from 192-kbit/s or
higher.
– Joint Stereo: This mode offers more efficiency and best quality for
stereo signals if the bitrate is 160-kbit/s or lower.
NOTICE Note that the ISO/MPEG encoder will switch automatically to pure Stereo mode,
if the bitrate is adequate. This behaviour you can see on a decoder: An alternate
switching between Stereo and Joint Stereo can be recognised. Of course this
switching is a feature of the ISO/MPEG Layer II encoder and is not audible.
– Dual Channel: There are no audible differences between Stereo and
Dual Channel mode. Only the multiplexing as well as the signalling in
the ISO/MPEG header is different. Select this mode if you insert totally
different signals on the left and the right channel.
