IT-85 Integrated amplifier
Owner’s Manual
VTL 28
using the same microcontroller chip, the VTL IT-85 could pick up signals
transmitted from this component as well. If your other remote unit also adopts
the same standard as the IT-85, 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 IT-85 while it is being used in these states and you can continue to safely use the IT-
85 until a solution is reached.
Please contact the VTL factory service department to report this problem, as
we are interested in knowing which models of stereo equipment could cause
this problem.
3. I am getting a noise and hum coming from my system when I turn the
IT-85s 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 for optimum noise reduction and safest
operation. If however there are too many paths to ground then a ground loop
hum can result. You should either contact your dealer or the VTL factory to
try to resolve this problem.
4. I am getting a noise and hum coming from my video source. What can
I do to eliminate the noise?
The noise may be coming in from your video Cable system. First disconnect
the VCR from the system to see if this will solve the problem. If it does then
you will need to try to lift the ground from the Cable TV wire, using a ground
lifter module sold at your local electronics supply store. If the problem still
persists, contact your VTL authorized dealer or the VTL factory service
department.
5. I am getting a ringing noise from the IT-85 when I touch or bump it.
What should I do?
One or more of the tubes in the IT-85 may have become microphonic (usually
the small tubes). Follow the procedures listed in this manual to remove the
tubes and change them for new ones.
6. My remote control hand held unit for the IT-85 is not working. What
should I do?
Look at the back of the remote control unit. Open the back cover. Locate the
two batteries inside the remote unit. Take the old batteries out and replace
them with new AA batteries. Slide the back cover on and snap it into place.
Test the remote unit to see if it is working properly.
