Nagra –
MPS
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.
Turn the modulometer selector to
display the desired information.
In the case of the MPS, the
Modulometer displays the following
information.
MAINS
Will display the AC power voltage. Depending on your country, the
nominal voltage will be 100, 115 or 230 V.
The actual scales are 90-110 V, 100-130 V and 210-250 V. Should the voltage be
below minimum or above maximum, this should raise concerns about a mains
power problem in your area. The MPS only displays the voltage, it does not affect it.
BAT
displays the battery level from 12 to 17 V. The output level of a fully
charged battery is 16.8 V. If the battery drops to around 13 V, the MPS will
automatically recharge it. If no battery is present, the needle will remain on the
far left of the meter.
1, 2, 3, 4
positions will
display the actual output level of the corresponding DC
output. The nominal level is 12.3 V, so the needle is a little bit above 12 V (as
shown in the picture). Should the voltage be significantly different, please contact
your dealer for support.
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.
