Rega DAC-R - Manual (Page 8)

In use
Power-up the DAC-R using the power switch on the front panel. After a few
seconds you will hear an audible click from the output mute relay and the
analogue audio will be active. Please note: the front panel will display the
previously selected setting’s displayed before the unit was last powered
down. If the currently selected input has an active source connected, the
‘Input locked’ LED, along with the appropriate incoming sample rate LED,
will illuminate. Unless the Input locked LED is lit, the sample rate indication
is irrelevant. By pressing the input selection switch you can select any one
of the inputs. When the Input locked LED is off, or there is a transmission
error, the internal soft mute is activated automatically. By pressing the Filter
selection switch you can select any one of the 3 available digital filters.
(The exact properties of these filters are outlined on page 6). Notably, each
one has a different result at low and high sample rates. The differences,
although subtle, are more noticeable at higher samples rates.
Digital Output & Optical inputs
The digital output mirrors the selected input. For example, when input 2
has been selected, the digital output will be the signal present on input
2 but cleaned up and re-clocked. This can be used to drive an auxiliary
piece of equipment if so desired.
The optical system used for optical inputs 1&2 is nearing its maximum at
192K. If you experience difficulties try the following: Use a higher quali-
ty or shorter lead. When using 3.5mm jack outputs commonly found on
computers and sound cards etc. Try and use a mini Toslink optical 3.5mm
jack connector lead and avoid using a 3.5mm to full size adaptor with a
standard full size Toslink lead.
