4 Information for installing

At high power level it is neccesarry to consider the wiring between the amplifier and speaker cabinets.
In most cases the amplifier is placed on top of the speaker cabinet, therefore a very short speaker cable can
be used for connecting the two. This is very good, because the shorter and thicker the loudspeaker cable,
the better.
Do not use an instrument cable for connecting speaker cabinets!
Use high quality / Neutrik / SPEAKON-SPEAKON speaker cable with at least 2x1,5mm2 or more cross
section. They are reliable, robust and have less influence on the sound.
Use a speaker cable in good condition and connect the speaker cabinet to the amplifier before you switch on
the amplifier.
Try to minimize the number of power strips used to connect the amplifier to the mains.
Use high quality, shielded instrument cable for connecting your instrument to the amplifier.
At high volume level the speaker cabinet might vibrate, so make sure that the placing is stable and the
amplifier can not move anywhere.
When you mount the amplifier to a rack case make sure there is at
least 2 cm of room near the side, because the cooling fan blows out
the heat on the left side of the amp (seen from the front).
To avoid mechanical stress of the mounting rails and the amp's front
panel mount the amp in such position that the feet are on the bottom of
the case.
You do not have to consider this if you have a „BHV4XXL", the light
version of this amplifier.
