Front panel controls
Disc drawer
The drawer of the K1 AV  is made of a material  with very 
high acoustic damping characteristics. Its flexible, floating 
support   system   eliminates   the   transmission   of 
mechanical vibration  to the  disc, which  would otherwise 
have an adverse effect on sound quality.
You  will   find   information  on   inserting   the   disc  and 
compatible disc formats in the chapter ‘The disc player /  
Compatible formats’.
HEADPHONES
Barrel socket (3.5 mm ∅) for  stereo headphones with  an 
impedance of at least 30 Ω.
When  listening  via  headphones  the  surrou nd 
mode  STEREO   should   always  be   selected, 
otherwise the centre channel information  will be 
lost   (see  chapter  'The   amplifier /  Basic  
functions, surround modes').
  ON
The machine’s On / Off button.
When you switch  the K1 AV on,  the screen displays  the 
selected listening source of a machine-specific  message. 
When switched  on,  the  machine  always  reverts to  the 
setting in  which  it  was  last  auditioned.  The  volume  is 
limited to ‘room volume” when switched on.
Caution:
The On / Off button  on the front panel  is not 
a mains  isolation  switch,  and  a few  of  the 
machine’s   sub-assemblies   remain 
connected  to  the mains   supply  when it   is 
switched off. If you know that the system will 
not  be   used  for   a  protracted   period,  we 
recommend  that   you   isolate   it  from   the 
mains  power  supply  by  disconnecting  the 
mains plug from the wall socket.
Auto-Off function
(disc mode only)
The  K1 AV  features  an   automatic  power-off 
function in  disc  mode.  If  the  player  goes  into 
‘STOP’ mode at the end of playing a disc, and if no 
controls are operated in the next twenty minutes, 
the K1 AV automatically switches itself off.
  Source select
Pressing this button selects the listening source you wish to 
use. Press the button repeatedly until the  screen displays 
the source to which you wish to listen.
The signal from  the selected  source can  now be played 
via the loudspeaker groups  A and B.  The same signal is 
also  present   at   the  TAPE-OUT  output   sockets   for 
recording.
  Monitor
Pressing   this   button   toggles   between   the   currently 
selected listening source and the tape monitor signal of  a 
recording  device  connected  to  the  K1 AV.  Press   it  a 
second time to return to the original signal.
When the  tape  monitor  signal  is  being played,  the   
symbol glows on the screen.
For more information on  the MONITOR function 
please refer to the chapter ‘The Amplifier / Basic 
functions, Monitor’.
 (Stop) /  (Open)
Pressing this button ends disc playback (STOP).
When the disc  has stopped playing,  pressing this button 
opens and closes the disc drawer (OPEN).
If you wish to  open the drawer  while the disc is  
playing,  hold  the  button   pressed  in  until  the 
screen  displays   the   message   ‘OPEN’.   The 
drawer  now  opens  as  soon  as  the   disc  has 
stopped spinning.
