The power on sequence will start, outputs 1 through 3 will be powered and then
the
remote output
triggers, for more information about the latter see page 10
The power down sequence order is similar; first the
remote output
will shut
down, then each output from 1 to 3. This allows a very smooth power on and off
for the system and should avoid any annoying clicks in the speakers.
Nagra Modulometer
The Nagra Modulometer was inherited from the second recorder developed by
Nagra back in 1952, the Nagra II. The Modulometer is a precision modulation
meter that displays the necessary information to perform the best possible
recording.
In the case of the CLASSIC PSU, the
Modulometer indicates the mains power
voltage.
Depending on your country, the nominal
voltage will vary from 100 to 240 V.
Should the voltage be below minimum or
above maximum, this should raise
concerns about a mains power problem in
your area. The CLASSIC PSU only displays
the voltage, it does not affect it.
LED and Modulometer intensity adjustment
This two-way toggle switch allows you to adjust the LED and Modulometer
backlight intensity. Pushing the toggle UP will increase the intensity, pushing it
down will lower the intensity all the way to complete extinction. There are 7
different levels.
