Appendix C: Service Information
Warranty Service
Details concerning Warranty Service are spelled out in Appendix D:
Information
If you think your TT24 has a problem, please do everything you can to confirm
it before calling for service. Doing so might save you from the deprivation of
your TT24 and the associated suffering.
These may sound obvious to you, but the following are things you can check.

Troubleshooting

No Power
• Our favorite question: Is it plugged in?
• Make sure the power cord is securely seated in the IEC socket and plugged
all the way into the AC outlet.
• Make sure the AC outlet is live (check with a tester or lamp).
• Is the POWER switch on? Make sure the POWER switch on the rear panel
is in the ON position (up).
• Is the Touchscreen on the front panel illuminated? If not, make sure the AC
outlet is live.
• Are all the lights out in your building? If so, contact your local power com-
pany to get power restored.
• If the Touchscreen is not illuminated, and you are certain that the AC outlet
is live, it will be necessary to have your TT24 serviced. There are no user
serviceable parts inside. See
Bad Channel
• Is the MUTE button pushed in?
• Is the input GAIN control for the channel turned up?
• Is the fader turned up?
• Is the signal source turned up? Make sure the signal level from the selected
input source is high enough to light up the Signal LED just above the chan-
nel's V-Pot.
• Is the channel assigned to a Group? Make sure the Group is assigned to the
Left and Right MAINS OUT.
