After switching off the pre-amplifier the amp does not automatically switch to STAND BY (after
approx. 5-10 min.) although the "auto" mode is selected.
•
Check whether a low humming or chirping noise is heard from the loudspeakers after switching off
the pre-amplifier. If this is so then scattering emissions within the cable are interfering with the
automatic switch-on circuitry. This is interpreting the interference as a music signal and reacts by
not switching off the amp. Remedy: Place your cable so that no further interference is
experienced. With balanced XLR cables this fault can also arise from an error in the pin setting.
Humming during music reproduction
•
This is mostly caused by a ground loop through the aerial amplifier or postal cabling. Check if the
humming stops following removal of the aerial cable from the tuner (and, if connected, the TV set
and video recorder). If this is successful then fit a sheath current filter to the aerial cables of these
receivers. (Your dealer will supply).
•
The shield of the AF-cable is interrupted, the cinch connector has poor ground contact (carefully
bend). The use of a symmetrical cable with wrong setting.
The display shows "OVERHEAT" and the unit switches off
•
Switch mains off and let the OVATION SA8.2 cool down for 15 minutes. Make sure that the unit is
placed according to the tips in chapter 2.1 Placement of the unit / cooling.
•
Make sure that there is no short circuit in the loudspeaker cables.
•
Check if one of your loudspeakers is defective.
The display shows "OVERLOAD" and the unit switches off
•
Switch mains off, fix failure and switch on again.
•
Make sure that there is no short circuit in the loudspeaker cables.
•
Check if one of your loudspeakers is defective.
The display shows "INTERNAL FAILURE or DC on input" and the unit switches off
•
Check if your preamplifier outputs excessive DC Voltage. (Some tube amps do so for a short time
after switching on).
•
The OVATION SA8.2 has been overdriven by excessive listening levels and switches off to protect
itself and the loudspeakers. Switch mains off and after one minute on again. Reduce the listening
level.
