TimeOut
TimeOutTimeOut
TimeOut – Menu Time Out Setting
If you find the 5 second time out period for the menu is too short, use this option
to change the time out period to 30 seconds.
do this: Open the Menu and step through until the display shows Timeout.
do this: Press the
Select button once and the display will show Normal.
do this: Press the
Select button again and the display will change to Long.
do this: Repeat this if you want to change back.
PLL
PLLPLL
PLL - PLL Tracking bandwidth
In slave mode, the PLL (Phase Locked Loop) synchronises Delius’ internal
crystal clocks to the incoming data stream. The system runs through two
different modes while locking. The final mode (fine lock) has a very narrow
bandwidth which rejects jitter generated by the source. This is the normal PLL
setting and gives best results with a stable source. It takes about 6 seconds to
lock.
Some CD players (even some very expensive ones!) generate a high level of
jitter and this can cause Delius to intermittently lose fine lock and mute the
Analogue Outputs. This menu option forces the PLL to stay in a wide-band
mode, allowing it to track larger variations in the source sample rate. In this
mode, the unit locks in less than 100 milliseconds.
To change the setting:
do this: Open the Function Menu and step through until the display shows PLL: Fine or
PLL: Wide.
do this: Press the
Select button to change between these two settings. Select PLL:Wide
if you are having locking problems.
If you are using Delius in master mode or with a Master Clock, the PLL should
be set to PLL:Fine, otherwise the jitter improvement will be lost.
NAud
NAud NAud
NAud - Non Audio Muting
Delius is normally set to mute if the Non-Audio message flag in the incoming
data stream is On – identifying the source as a corrupt data stream, CD-ROM or
other non-audio format.
We have found that some audio CDs actually have the Non-Audio flag set! To
listen to such disks, the automatic muting must be TEMPORARILY disabled.
IMPORTANT! Listening to a CD-ROM is very unpleasant and can cause damage to your
ears, power amplifier and loudspeakers. Use this mode with care. You
should turn Non-Audio Muting back on as soon as possible – we advise you
not to leave Delius in this mode.
Override Non-Audio Muting x
The most convenient way to over-ride the Non-Audio muting for individual
tracks is as follows.
do this: When NonAudio is displayed, press the Mute button. Delius will play the track
normally. Press the Mute button again to mute the outputs and restore Non-
Audio muting.
The over-ride is cancelled at power down or when the unit re-locks, avoiding the
risk that the unit will be left for extended periods without protection.
