1) Connect the stereo input AUDIO IN (6) to a line level output
of the unit of which the 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 INPUT (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. For this purpose, see 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 is obtained if the "0 dB" LEDs light up during
music peaks. In case of overload (ranges exceeding "0 dB"
light up), reduce the level of the signal source.
7) For switching off, press the POWER switch. If the VU meter
is not used for a longer period, disconnect the plug-in trans-
former from the mains socket as the transformer will have a
low current consumption even if the VU meter has been
switched off.
