Why am I getting noise and hum from my VTL TL5.5 II Signature?
To address noise and hum when turning on your VTL Amplifier, ensure as many components as possible are connected to a clean AC ground. For optimal quietness, plug all components into the same ground potential or AC outlet. If a ground loop hum occurs due to too many ground paths, contact your dealer or the VTL factory for assistance.
What to do if VTL TL5.5 II Signature doesn't turn on?
If your VTL Amplifier doesn't power on, first check the power cord connection to both the amplifier and the AC outlet. If the power source is fine, inspect the fuse in the back panel. Replace the fuse if it's blown. If the issue continues, contact your authorized VTL dealer.
Why is there noise and hum from video source with VTL TL5.5 II Signature Amplifier?
If you're experiencing noise and hum from your video source with your VTL Amplifier, the issue might originate from your video cable system. Try disconnecting the VCR to see if that resolves the problem. If it does, attempt to lift the ground from the cable TV wire using a cable ground lifting transformer. If the problem persists, contact your VTL authorized dealer or the VTL factory service department.
How to fix VTL TL5.5 II Signature remote control not working?
If your VTL Amplifier's remote control isn't working, open the back of the remote by loosening the four screws. Replace the old AAA batteries with new ones. Retighten the screws and test the remote. If it still doesn't work, contact your VTL authorized dealer or the VTL factory service department.
Why does another remote control affect my VTL Amplifier?
Your VTL preamplifier remote control receiver unit decodes signals coming from a proprietary micro controller code set that is based on the Phillips RC5 code set. 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.
Why is my VTL TL5.5 II Signature volume too loud on CD?
If the volume level is too loud at setting '01' when playing a CD on your VTL Amplifier, it may be due to a high output level from your CD player. You can 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 internal gain switch of the TL5.5 to low gain to attenuate the input by approximately 12dB.
What to do if VTL Amplifier makes ringing noise?
If your VTL Amplifier produces a ringing noise when touched, one or more of the tubes may be microphonic. Follow the procedures listed in this manual to remove the tubes and change them for new ones.
