Operation
Start Up
1. Secure all rear-panel connections
between Reference DAC, preamplifier or
power amplifier(s), and input sources.
2.
Plug three-prong power cord from
rear of chassis into grounded A.C. wall
outlet. The Power switch defaults to ’off’
when the unit is plugged into a power
receptacle.
3.
Press power switch (either remote or
front panel). The display will remain
black for approximately 8 seconds, after
which the Reference DAC splash screen
will appear. Once the splash screen is
gone, the main menu page is displayed,
and a countdown timer will show
the seconds until the unit is ready for
operation. After countdown, the unit will
be in Mute.
4.
Select input source, unmute and select
volume level.
Note
The Reference DAC is equipped with a
variable output and volume control. If
you are using this unit in conjunction with
a preamplifier, please set the volume to a
static location and use the volume control
on the preamplifier. A volume setting
of 66 is equivalent to Line Out on most
components.
Shut Down
1. Activate ‘Mute’ function.
2. Set Volume level to 0.
3.
Turn off power amplifier(s) and
preamplifier.
4.
Press Power switch to ‘off’.
Turn off input sources.
Break-in
All quality stereo equipment benefits from
a break-in period; during this time, the
various components, wiring and solder
connections change as electrical signals
pass through them. While your Reference
DAC will sound fantastic out of the box,
it will only improve with continued use.
Note
The Reference DAC should be the first
component turned on in your system
(along with any additional sources). If
the Reference DAC is turned on after the
amplifier, and the preamplifier is also
powered, it will amplify any extraneous
turn-on noises the preamplifier or other
source components might generate, which
could potentially damage the loudspeakers.
Good operating practice dictates that
the amplifier should be turned on last,
and turned off first in an audio system.
