1 Please use a commercially available adapter when connecting the Dolby Digital RF (AC_3RF) outputiack 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 this unit, 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" iacks to this
unit
(2) Dolby Pro Logic 1I
• Dolby Pro Logic [! 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 [] can be used to decode not only sources recorded in Dolby Surround (-_ ) but also regular stereo sources into five channels
(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 H 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 l[ 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 (see page
30).
._ 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 cassettes to be played on stereo VCRs, as well
as for the stereo broadcast signals of FM radio, TV, satellite broadcasts and cable TV
Decoding these signals with Dolby Pro Logic makes it possible to achieve multi_channel surround playback. The 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
_I} 2 channel PCM stereo signals
_2} 2-channel Dolby Digital signals
When either of these signals is input to the AVRq 602, the surround mode is automatically set to Dolby Pro Logic ]I when the "DOLBY/DTS
SURROUND" mode is selected.
• Sources recorded in Dolby Surround are indicated with the logo mark shown below,
