Additional Information
Surround
The AVR-1306 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 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.

The following are general examples. Also refer to the player's
operating instructions.

LD (VDP)
DVD
Others
(satellite broadcasts,
CATV, etc.)
1: Please use a commercially available adapter when
connecting the Dolby Digital RF output terminal of the LD
player to the digital input terminal.
Please refer to the instruction manual of the adapter when
making connection.
Dolby Pro Logic
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
2 ch
Digital surround on the AVR-1306, switch the DVD player's
output mode to "bit stream". In some cases players are
equipped with both "bit stream + PCM" and "PCM only"
4 ch
digital outputs. In this case connect the "bit stream +
PCM" terminals to the AVR-1306.

Additional Information
• 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
II
Logic, but with Dolby Pro Logic 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
( page 40).
Sources recorded in Dolby Surround
• These are sources in which three or more channels of surround
have been recorded as two channels of signals using Dolby
Surround encoding technology.
• Dolby Surround is used for the sound tracks of movies recorded
on DVDs, LDs and video cassette tapes, as well as for stereo
broadcast signals from FM radio, TV, satellite broadcasts and
cable TV.
• Decoding these signals with Dolby Pro Logic
possible to achieve multi-channel surround playback.
signals can also be played on ordinary stereo equipment, in
which case they provide normal stereo sound.
• There are two types of DVD Dolby surround recording signals.
q 2-channel PCM stereo signals
w 2-channel Dolby Digital signals
• When either of these signals is input to the AVR-1306, the
surround mode is automatically set to Dolby Pro Logic
the DOLBY/DTS SURROUND mode is selected.
