ONLY connect the amplifier to a (professionally installed) wall socket with earth or ground and
the corresponding voltage setting, as indicated on the back of the amplifier. Any faulty
connection will invalidate the warranty.
To prevent damage to your loudspeakers it is advisable, both at switching ON and OFF to turn
the volume control fully to the left. Fully anti-clockwise sets the volume at its lowest level. The
same applies when changing sources.
The correct order for ON/OFF switching of the various products is as follows:
ON:
always first the source, then the pre-amplifier, followed by the power amplifiers.
OFF: always first the power amplifiers, then the pre-amplifier, followed by the source.
Only connect the DC and/or RC outputs of one product exclusively to the corresponding DC or
RC inputs of the other product. Do not connect crosslink wise and also not with any audio input
or output.
The Red (+) loudspeaker terminal must never be connected with earth or ground, or to be
connected with the Red (-) loudspeaker terminal. Both are Red because this is a balanced or
symmetrical amplifier.
Do make sure that there is always enough ventilation around the amplifier in order for it to
remain at its desirable temperature level.
Do not put any magnetic devices near or on top of the amplifier, e.g. floppy disks. This can
cause irreparable damage to such devices.
If it is necessary to replace the fuses, use only Slow fuse(s) with the exact same value. The
fuse holders are positioned inside the amplifier and should only be replaced by an authorized
Van Medevoort Service Center. There are no user serviceable parts inside.
If you experience any problems, always contact your nearest authorized Van Medevoort
Service Center.
