Your DAC20 has seven digital inputs: Three coaxial, three optical
and one AES/EBU. Using the
input
and
source
buttons you can
choose any one of these digital inputs to convert to analogue
(1)
.
The
input
button allows you to select the AES/EBU input or one
of the other three inputs (either coaxial or optical). The input you
have selected is shown by a series of LEDs on the front panel
marked
1
,
2
,
3
and
aes
. Pressing the
input
button steps through
1
,

and back to

.
The
source
button allows you to select the
coaxial
or the
optical
inputs. The source you have selected is shown by one of two
LEDs on the front panel marked
coaxial
and
optical
. Pressing
the
source
button switches the input from
coaxial
to
optical
and back

If you are using the
aes
input, the
source
button has no effect.
Your DAC20 has a microprocessor-controlled muting system to
prevent switching noises (which could damage your equipment)
from being sent to your amplifier and loudspeakers.
The LED on the front panel labelled
mute
will light when the
output is muted.
The DAC20 turns off the analogue output for a short time
whenever you change the input using the
input
or
source
buttons.
Press the
mute
button on the front panel to turn off the analogue
output. Press it again to turn the sound back on.

1. The DAC20 remembers the input and source settings even when power is
disconnected
2. The
source
setting remembers the
