OVATION A 6.3 / 8.3
3.2.6 The display shows "OVERHEAT" and the unit
switches off
Switch off the mains supply via the mains switch (8) and
allow the amplifier to cool down for approx. 15 minutes.
Check that the amplifier is correctly installed (see 1.3 Instal-
lation and cooling).
Check your speaker cables for short circuits.
3.2.7 The display shows "OVERLOAD" and the unit
switches off
Switch off the mains supply via the mains switch (8).
Check your speaker cables for short circuits.
3.2.8 The display shows "INTERNAL FAILURE or DC
on input" and the device switches off
Check to see if your preamplifier is outputting DC voltage
(some tube preamplifiers do this for a short time after powe-
ring on).
The MA 8.3 / SA 8.3 was overmodulated due to heavy output
levels. In this case it switches off automatically to protect
itself and the loudspeakers. Switch off the power amplifier,
reduce the volume and switch on the power amplifier again.
