DOLBY/DTS SURROUND

Surround
The AVR-M330 is equipped with a digital signal processing circuit that lets you play program sources in the surround mode to achieve the same
sense of presence as in a movie theater.
Dolby Surround
(1) Dolby Digital
Dolby Digital is the multi-channel digital signal format developed by Dolby Laboratories.
Dolby Digital consists of up to "5.1" channels - front left, front right, center, surround left, surround right, and an additional channel exclusively
reserved for additional deep bass sound effects (the Low Frequency Effects – LFE – channel, also called the ".1" channel, containing bass
frequencies of up to 120 Hz).
Unlike the analog Dolby Pro Logic format, Dolby Digital's main channels can all contain full range sound information, from the lowest bass, up
to the highest frequencies – 22 kHz. The signals within each channel are distinct from the others, allowing pinpoint sound imaging, and Dolby
Digital offers tremendous dynamic range from the most powerful sound effects to the quietest, softest sounds, free from noise and distortion.

(satellite broadcasts, CATV, etc.)
1 Please use a commercially available adapter when connecting the Dolby Digital RF output jack of the LD player to the digital input jack.
Please refer to the instruction manual of the adapter when making connection.
2 Some DVD digital outputs have the function of switching the Dolby Digital signal output method between "bit stream" and "(convert to)
PCM". When playing in Dolby Digital surround on the AVR-M330, switch the DVD player's output mode to "bit stream". In some cases
players are equipped with both "bit stream + PCM" and "PCM only" digital outputs. In this case connect the "bit stream + PCM" jacks
to the AVR-M330.

Dolby Pro Logic IIx

(2)
Dolby Pro Logic IIx furthers the matrix decoding technology of Dolby Pro Logic II to decode audio signals recorded on two
channels into up to 7.1 playback channels, including the surround back channel. Dolby Pro Logic IIx also allows 5.1-channel
sources to be played in up to 7.1 channels.
The mode can be selected according to the source. The Music mode is best suited for playing music, the Cinema mode
for playing movies, and the Game mode for playing games. The Game mode can only be used with 2-channel audio
sources.
(3) Dolby Pro Logic II
• Dolby Pro Logic II is a new multi-channel playback format developed by Dolby Laboratories using feedback logic steering technology and
offering improvements over conventional Dolby Pro Logic circuits.
• Dolby Pro Logic II can be used to decode not only sources recorded in Dolby Surround (
(front left, front right, center, surround left and surround right) to achieve surround sound.
• Whereas with conventional Dolby Pro Logic the surround channel playback frequency band was limited, Dolby Pro Logic II offers a wider
band range (20 Hz to 20 kHz or greater). In addition, the surround channels were monaural (the surround left and right channels were the
same) with previous Dolby Pro Logic, but Dolby Pro Logic II they are played as stereo signals.
• Various parameters can be set according to the type of source and the contents, so it is possible to achieve optimum decoding .
