Nagra –
TUBE DAC
With MPS and CLASSIC PSU:
Always use the first available output of
the power supply device for the TUBE DAC DC digital input and the
consecutive one for the TUBE DAC DC analog input (sequential start
of MPS/CLASSIC PSU outputs, it is better to first start digital section
of TUBE DAC).
First start up power supply unit by turning front selector to
ON
position. Wait
for the end of starting process (MPS: when the 4 output LEDs on front panel
are switched ON, CLASSIC PSU: when the blinking LED on the right side of
front panel switches OFF).
Now you can start up the TUBE DAC by selecting the desired position on front
selector.
Disconnection
First, turn the TUBE DAC front selector to
OFF
and wait for its complete
shutdown (when display and modulometer backlight switch OFF).
Then, turn the power supply unit front selector to
OFF
and wait for its complete
shutdown (when LEDs and modulometer backlight switch OFF).
Now you can safely remove LEMO plugs from the TUBE DAC and MPS/CLASSIC
PSU back panels:
Grip the fluted section of the plug, between thumb
and index fingers as shown in the picture and pull
the crown of the connector backwards.
