3. Menu system 

 
 
3.1 Operating the menu system 

 
The  settings  for  customizing  your  OVATION  SA8.2  are 
done via the menu system. The menu system works while 
the unit is on as well as in stand by mode. 
 
To access the menu just press the knob (3c) in the middle 
under  the  display  (2).  The  display  shows  now  the  SET 
OPERATING  MODE  menu.  The  actual  setting  has  a 
frame  around.  The  setting  can  be  changed  by  pressing 
the <VALUE> knobs (3d, 3e). Changing to other menus is 
done by pressing the <ITEM> knobs (3a, 3b). Just press 
the  EXIT  knob  (3c)  to  leave  the  menu  and  store  the 
settings. If no knob is pressed for longer than 10 seconds 
the unit will exit the menu automatically. 
 
 

3.2 SET OPERATING MODE 
 

 

permanent:

 When switched on using the mains switch (1) the unit will operate permanently until it 

is switched off. 

 

remote:

 In this mode the unit is controlled via inaudible digital signals sent over the AF cable. It 

will switch to operate and to stand by synchronously with the preamplifier. Also the dimming of the 
display will be performed according to the setting on the preamp. This mode makes sense, if you 
use a AMP pre mk2 as preamplifier. 

 

trigger:

 Switching to operate and to stand by is controlled via the trigger input (9). 

 

auto:

  The  OVATION  SA8.2  switches  on  automatically  as  soon  as  the  pre  amplifier  delivers 

musical signals and to stand by when the pre amplifier has not delivered a signal for more than 5 
to 10 minutes. 

 
 

3.3 SET DISPLAY MODE 
 

 

bar  &  value:

  While  operating  a  bar  informs  you  about  the  actual  output  level.  The  peak  output 

power is displayed numerically. If demanded output power exceeds the maximum the display will 
show  "CLIP"  to  indicate  this.  In  this  case  we  recommend  to  reduce  the  volume  in  order  not  to 
damage the tweeters. 

 

value:

  The  peak  output  power  is  displayed  numerically.  If  demanded  output  power  exceeds  the 

maximum the display will show "CLIP" to indicate this. In this case we recommend to reduce the 
volume in order not to damage the tweeters. 

 

dis off:

 The display is dark and shows only "MENU".

 

 
 
3.4 SET BRIGHTNESS 
 

  Selects the display brightness (100%, 60%, 30%).   

REMARK:  The  display  brightness  can  also  be  remote  controlled,  see  3.2  SET  OPERATING 
MODE / remote. 

 

3.5 SET LOAD IMPEDANCE 

 

  To obtain correct values in the power display it is necessary to select the speaker impedance (2, 

4, 8 Ohms) according to your speakers. This setting is only for calibrating the power display and 
has no influence on the amplifier itself.
