Global – Global/Local Volume
Elgar Plus can store Volume settings in two ways:
• Applying the same Volume setting to all inputs (Global volume).
• Using different settings for each input (Local volume, or Input specific). This
is useful where the average loudness (and so the preferred Volume setting)
changes from source to source.
To change this setting:
do this: Open the Function Menu and step through until you reach the Vol page. The
display shows Vol:Glob or Vol:Inp.
do this: Press the
Select button to choose one of these settings and wait for time out.
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 Elgar Plus’ 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 Elgar Plus 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 Elgar Plus in master mode or with a Master Clock, the PLL
should be set to PLL:Fine, otherwise the jitter improvement will be lost.
