English version
There is a slight delay whilst the unit changes filters, during which it will not
respond to further button presses. Selecting the most appropriate filter is simply
a matter of flipping through the options as you play a CD and choosing the one
that you think sounds best. Try listening for changes in imaging, ambience and
low level information, bass definition and vocal clarity.
You can change filters more quickly from the listening position using the
button on the Remote Control, see page 43.
This is set on a per input basis, and determines whether that input acts as a
master or a slave. The options available (independently, for each input) are:
MS:Slav
(Slave) In slave mode (most DACs operate in this mode)
the PLL locks to the incoming signal, and tracks it. This
setting is not available in DSD mode.
MS:Mastr
(Master) In master mode, Elgar Plus acts as a master
clock, and outputs an autonomous 44.1kHz clock on
Wordclock
transport. The CD transport output is then locked to the
DAC VCXO, and the DAC only has to decode the data
coming in – it knows the clock frequency.
MS:Sync
In sync mode, the PLL locks to a master clock (or other
clock source) connected to
data from the selected input. The source must also be
locked to the master clock, or generating the clock. If the
Wordclock is not at a standard frequency, is out of
capture range or is a "superclock", the unit will display
Locking...,
for 10 seconds and reset itself to MS:Slav.
There are some restrictions on master mode operation. The source (usually a
CD transport or player) must run at 44.1kS/s ONLY. Elgar Plus may be used in
this mode with an Upsampler, but the Upsampler output must be set to
44.1kS/s, 88.2kS/s, 176.4kS/s or DSD.
If you wish to use master mode (we recommend this for CD transports that will
accept a 44.1kHz word clock), then do the following:
Connect the CD transport (or other source equipment) to Elgar Plus and select
that input.

(Run through this sequence again if you want to change back to MS:Slav.)
If a source is connected and selected, Elgar Plus will display

If you are using an Upsampler set for 176.4kS/s Dual AES output, select the
input. The displays will then be
