9 Commissioning and operation
After you have set up your speakers and connected the power supply cables as
described in point 8, connect the signal cables.
The output jacks L/R from the preamp/amplifier to the XLR -
Input sockets on the V3 speakers (see picture 2)
The input gain on the V3 is set to -10dB as default. The volume control of the
preamplifier ect. Must be set to the lowest value to avoid overmodulation.
Now switch on the V3 speakers at the power switch, as well as the preamplifier and
the music source.
Then turn up the volume control on the preamplifier to room volume. If the volume
control is between 50% and /75%, you can leave the setting on the V3 gain control. If
at a value of 75% the volume is too low, turn the Gain control clockwise to the
desired volume. Otherwise, decrease the volume by turning the Gain knob
counterclockwise.
If your preamplifier does not have balanced XLR audio outputs but RCA (Cinch)
connectors, use an appropriate adapter or an audio cable with RCA plugs to XLR-F
3x1pin connectors.
The loudspeaker can be adapted to your requirements by acoustic room calibration.
The preset switch on the loudspeaker stores 8 presets for the most common room
parameters, which can be activated as required. In general, this selection of presets is
sufficient to adjust the speaker to the room.
