5 Setting into Operation

Prior to connecting any units or to changing existing connec-
tions, switch off the VU meter .
1) Connect the stereo input AUDIO IN (6) to a line level output
of the unit whose level is to be indicated, e . g . effect unit,
mixer .
2) A subsequent unit (e . g . amplifier, second mixer) can be
connected to the stereo feed-through output AUDIO OUT
(7) . Connect the output AUDIO OUT to a line level input
of the unit .
3) Connect the supplied plug-in transformer to the jack POWER
SUPPLY IN (5) and then to a mains socket (230 V/ 50 Hz) .
4) Prior to the first operation, a basic adjustment of the
VU meter must be made (☞ chapter 4) .
5) Switch on the VU meter with the POWER switch (4) . Select
the display mode of the LEDs (3) via the switch (2):
Position BAR = bargraph display
Example: If a level of −12 dB is measured for a channel,
all LEDs "−45 dB" to "−12 dB" will light up .
Position DOT = dot display
Example: If a level of −12 dB is measured for a channel,
only the two LEDs "−12 dB" will light up .
6) Feed the audio signals to the VU meter and read the signal
levels on the LED display . An optimum adjustment of the
signal source has been obtained when the "0 dB" LEDs light
up during music peaks . In case of overload (ranges exceed-
ing "0 dB" light up), reduce the level of the signal source .
7) For switching off, press the POWER switch . If the VU me-
ter is not used for a longer period, disconnect the plug-in
transformer from the mains socket as the transformer will
have a low current consumption even when the VU meter
has been switched off .
