The VT-3 has a STANDBY
MODE feature that is automatic and rcquires no usef adjustments. When no signal is
prcsent
for 45 minutes,
the VT-3 controller
goes
into Standby l\/ode, and it will use a minimum of
power
to
remain
"asleep".
When
the system
is
used
again, it immediately turns on as soon as a signal is received.
There is no need to turn ihe VT-3s on
and off every
time they are used.
The VIDEO MODE TRIGGER INPUT is an auxiljary trigger input that
fo.ces the VT-3 into the VIDEO mode. N,4anJlr
preamplifiers
and
processors
have a trigger output
(+4.sVDC
to
+25
VDC) which is enabled when the user selects a video-
function, such as DVD of DSS.
lf
the trigger
is
aclive,
the VT-3
processor
will switch into VIDEO mode
if
the
previous
mode
was l\rUSlC or stay in VIDEO if it was already
in that mode- The system will remain in the
VIDEO
mode until
it is
switched
back to MUSIC mode either by
the lR remole or by the Conkoller
I Operation
The VT-3 system
was
designed
to handle a wide range of listening leveis, but every
component has limits. lt is important
to use common
sense and listen for signs of
possjble
distress
from the speakers. Noticeable distortion or harsh breakup
is an indication
that the speaker is running beyond
its
capacity, and
the volume should be decreased.
lf
you
feel heat
emanating
from the front of any of the speakers, reduce the
level immediately. Speaker damage
most
often occurs
from
sustained
high volume levels, not frcm transient sounds or
brief musical
peaks.
Excessive
boosting of bass, treble, of
equalizer
controls can worcen the
problem
and
is not recommended-
I Maintenance
Your VT-3s have been
designed for
years
ol trouble{ree operation and
require minimal maintenance under
nofmal
use.
The VT-3 cabinet
may be cleaned using a damp cloth or a mild,
non-abrasive
glass
cleaner.
To
clean
the
gri
l, first remove
it from the speaker,
then brush lightly with a soft brush or use a
vacuum on its lowest setting.
The VT-3
controller
may be

wiping with a lint-free cloth. Do not expose the tower or
Conkoller to direct sunlight,
high temperatures of
