VTL TL2.5, Owner'S Manual

3.  

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 for optimum noise reduction and safest 
operation. If however there are too many paths to ground then a ground loop 
hum can result, and 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.  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 preamplifier when I touch or bump it.  
What should I do? 

One or more of the tubes in the preamplifier may be the source of the 
problem. 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 preamplifier 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. 

If the remote control unit is still not functioning properly, contact your VTL 
authorized dealer or the VTL factory service department. 

7.  Using the remote control from another stereo component in my system 

affects the control of my VTL TL2.5.  Why is this happening and what should 
I do? 

Your VTL TL2.5 is equipped with a remote control receiver unit that decodes 
signals coming from a NEC microcontroller chip with a unique respond code. 
If you own another stereo component that comes with a remote control unit 
using the same microcontroller chip, the VTL TL2.5 could pick up signals 
transmitted from this component as well. If your other remote unit also adopts 
the same standard as the TL2.5, then there is a chance that the signals from
