4. Care of the casing 

 
The surface and printed text on the casing is largely scratch resistant. The casing may be cleaned with 
a mild soap solution or spirit based glass cleaner (use economically) and a soft lint free cloth. 
 

NOTE 
 
Care should be taken during cleaning to ensure that no liquids can ingress into the casing. It is 
advised  for  safety  reasons  to  remove  the  power  cable  from  the  electrical  supply  before 
cleaning  the  casing  with  a  damp  cloth.  Do  not  use  solvents  or  abrasives  for  cleaning.  This 
could damage the surface. 

 
 

5. If at first you don’t succeed... 

 
Some  suspected  defects  of  the  equipment  are  very  often  found  to  have  been  caused  by  faulty 
operation.  Before  you  consult  us  please  check  the  functioning  of  your  stereo  amp  according  to  the 
following checklist: 
 
 

Unit is ON, but display shows nothing 

 

  Switch the display mode from "off" to a different setting. (see 2.6 and 3.3 DISPLAY MODE) 

 
 

Unit is ON, but loudspeakers remain inoperative 

 

  Test initially whether the pre-amplifier and the selected signal source are operating correctly. This 

is best achieved by checking the functioning of the pre-amplifier with head phones. Remember to 
remove the head phones jack after use, otherwise the pre-amplifier will not emit a signal. 

 

  Ensure that there are no breaks or short circuits in the signal cable between the stereo amp and 

the pre-amplifier.  

 

  Test  the  connecting  cable  between  the  Stereo  amp  and  the  loudspeaker  for  a  short  circuit  or 

break. 

 
 

Unit does not switch from STAND BY to OPERATE or switches while listening to music from 
OPERATE to STAND BY. 
 

  This can happen when the OVATION SA8.2 is operated in "auto" mode and you are listening at 

low levels. Then the incoming Voltage from the preamp is too low to trigger the auto-circuit. In this 
case we recommend to switch the unit to "permanent" mode or to use of a trigger cable (see 3.2 
OPERATING MODE). 

 

 

  If the unit is operated in "trigger" mode please check the trigger cables between preamp and the 

OVATION SA8.2 and ensure that there are no breaks or short circuits in the cable.   
 

The  unit  is  operated  in  "remote"  mode  without  using  a  suitable  preamp  (AMP  pre  mk2).  Choose  an 
different operating mode (see 3.2 OPERATING MODE).
