Amplifier menu point BASS (low bass lift)
Explanation:
The system features the facility to switch on active low bass lift, producing better deep bass 
reproduction especially with small, compact loudspeakers.
Operation:
The low bass lift is switched off using the Õ button (display 'NORM') and switched on with 
the Ö button (display 'EXTD').
At  the  'BASS NORM'  setting  the  low  bass  lift  is  switched  off   (correct  setting  for  large 
loudspeakers); at the 'BASS EXTD' setting it is  switched on (correct setting for compact  and 
bookshelf speakers).
The screen displays a glowing  symbol when low bass lift is switched on.
Amplifier menu point Sub-woofer volume (SWLEV)
Explanation:
The K1 AV offers the facility to adjust the volume level of the sub-woofer (if present in the 
system).
Operation:
The value can be set within the range -6 to +6 using the change buttons Õ / Ö.
This  menu  point  only  appears  if   the  sub-woofer  is  switched  on  in   the 
'Amplifier setup menu / Sub-woofer cut-off frequency' menu.
Amplifier menu point Centre volume (C-LEV)
Explanation:
The K1 AV offers the facility to  adjust the volume of the  Centre loudspeaker (if present in 
the system) to match that of  the primary speakers. Adjust the  level of the Centre speaker  
so that it is as loud as the main loudspeakers.
The Centre  loudspeaker  is intended  to  fill the  ‘acoustic  hole’ between  the 
main loudspeakers; it should not be dominant.
Since the  optimum  volume of  the  Centre loudspeaker  varies  greatly with  the  playback 
mode (3CH  Music /  3CH Movie),  the value  set here  is stored  separately for  Music and 
Movie modes.
Operation:
Use the Õ / Ö buttons to  increase or reduce the volume of  the Centre loudspeaker in 
1.25 dB increments by up to 7.5 dB (screen displays '-6' ... '+6').
