CONNECTION AND COMMISSIONING
unit, can be used to add another output stage (eg
for sounding a further room) or an active subwoofer
to the volume controled Stereo output (line level),
of the currently selected source. The output level of
the pre-amplified output "PRE-OUT" (20) depends
on the volume setting, the sound control (BASS,
TREBLE) and the insertion of a headphone. Connect
this signal output to the signal input ("LINE IN" /
"INPUT" etc.) of the power amplifier / active sub-
woofer using commercially available RCA cables.
Connecting a headphone
A headphone equipped with a 3.5 mm jack plug can
be plugged into the headphone socket " " (9) on
the front of the unit. All headphones with an impe-
dance between 32 and 600 Ohm can be used.
Unsuitable headphones with another impedance
may damage the unit or produce an unexpectedly
high volume that can damage your hearing. As long
as a headphone is plugged in, the speakers are
switched off. Before plugging in, be careful to redu-
ce the volume of the "VOLUME" knob (11) (this
knob is also used to adjust the volume of the head-
phone).
Connecting the speakers
Use cables with sufficient cable cross-section to con-
nect your speakers to the VT-80MK. Ensure that bare
loudspeaker wires can never touch each other or the
back of the housing! No active speakers may be con-
nected! Use only speakers with a nominal impedance
of 4 - 8 Ohm. In addition, you have the possibility to
operate the amplifier with 4 loudspeakers. For this,
only use speakers with a nominal impedance of 8 -
