speaker setup If you select the stereo button, the remaining buttons will be grayed out and
made inactive. In this mode, the CDP-300 acts as a versatile two channel disc
player that can handle many diff ering disc formats. In a stereo confi guration,
many of the decisions you need to make in a multichannel system no longer
apply.
By selecting the multichannel button, you will be able to engage the bass
management system within the CDP-300.
Having bass management in your DVD player is especially valuable when
playing DVD-Audio discs using the analog outputs. DVD-Audio discs usually
contain fi ve full-range channels plus a dedicated LFE (Low Frequency Eff ects)
channel. By telling the CDP-300 which of your speakers is less than full
range, it can redirect the bass that would otherwise be sent to those smaller
speakers to those that will be able to reproduce it. Th
is results in both improved
performance and better reliability, since you are not asking speakers to do
anything other than what they were designed to do.
audio delay Modern video displays make extensive use of video processing (as does the
CDP-300 itself ). Th
is circuitry converts standard defi nition video (480i or 576i,
depending on your local broadcast standard) to a format that is compatible with
modern fi xed matrix displays such as LCD, DLP or plasmas.
However, this conversion process takes some small amount of time, causing a
“lip sync” problem between the audio (which has not been delayed appreciably)
and the video (which has been delayed for processing). While some people are
more sensitive to this problem than others, anyone who perceives a consistent lag
between the audio and video will fi nd it quite annoying.
Th
e audio delay function of the CDP-300 addresses this by delaying the audio
by anywhere by up to 200 milliseconds. Th
is range of adjustment should be
adequate to handle any video processing delay you might fi nd in your system.
Note that the best use of this delay is to compensate for any delay introduced
by the CDP-300’s own video processing (assuming you are one of the ones who
are sensitive to this sort of thing). Th
e CDP-300 can only delay audio coming
from itself, and has no control over (for example) broadcast television you may
be watching. If your television introduces enough video processing delay to be
noticeable, you would be better off using the audio delay feature of your A/V
preamplifi er/processor (assuming it has this capability—which Classé processors
do have.)
