Troubleshooting

1. When I power on the preamplifier from the rear rocker switch, nothing happens.
What should I do?
Check to make sure that the power cord is properly connected to the
preamplifier and the AC outlet. If there is no problem with the power source,
check the fuse unit in the back panel of the preamplifier. If the fuse is blown,
change the fuse, and turn the power on the preamplifier again. If the problem
still persists, contact your authorized VTL dealer immediately.
2. When I play my CD the volume level at 01 seems to be too loud. What is the problem
and what can be done about it?
Some CD players have a high output level, and require padding down. Either have
the manufacturer of the player/DAC adjust the output to a lower level, or take
your preamplifier to your dealer and ask them to set the input pad jumper on the
CD1 input. This will attenuate the input by approximately 12dB, and can be
further adjusted if required.
3. Using the remote control from another stereo component in my system affects the
control of my VTL preamplifier. Why is this happening and what should I do?
Your VTL preamplifier is equipped with a remote control receiver unit that
decodes signals coming from a proprietary micro controller code set that is based
on the Phillips RC5 code set. If you own another stereo component that comes
with a remote control unit using the same micro controller code set, the VTL
preamplifier could pick up signals transmitted from this component as well. If
your other remote unit also adopts the same standard, then there is a chance that
the signals from both remotes may be interpreted as the same. If the functions
with the same command are different for both units then one or other of the
remote controls will have to be re-programmed. Contact your VTL Dealer or the
Factory for a solution to this problem. Note that in either case there is no damage being
done to your VTL preamplifier while it is being used in these states, and you can continue to
safely use the preamplifier until a solution is reached.
Please contact the VTL factory service department to report this problem, as we
would like to be made aware of which models of stereo equipment could cause
this problem.
4. I am getting a noise and hum coming from my system when I turn the amplifiers on.
What can I do to eliminate the noise?
It is recommended that you connect as many components as possible to a good
clean AC ground in your system, and for quietest operation it is recommended
that all components be plugged into the same ground potential (or same AC
