Automatically detects the type of audio signal being
input (Dolby Digital, Dolby Pro Logic, or standard two
channel stereo) and performs the proper decoding if
necessary. This mode presents the sound as it was
recorded/encoded, without adding any effects.

mode to hear the source sound exactly as it
was recorded.

Outputs the sound from the front left and right
speakers onl3zStandard two channel (stereo) sources
completely bypass the sound field processing. Multi
channel surround formats are downmixed to two
channels.
This allows you to play any source using
only the front left and right speakers.
Notes
• No sound is output from the sub woofer when the 2 CHANNEL mode is selected. To listen to two channel (stereo) sources using the front
left and right speakers and a sub woofer, use the AUTO FORMAT DECODING mode.
• When you select "Micro Satellite Speaker", internal sound processor will automatically redirect bass sound to subwoofer. If you want to
listen to two channel (stereo) sources under this setting, we recommend that you choose AUTO FORMAT DECODING mode so that you
can take advantage of your subwoofer to get back correct bass signal.
