 BASIC OPERATIONS (CONT.)
REPLAY  LOOP - The reloop  (8) function allows you to return to your stored 
loop at any time. The In  B utton (10) and out  B utton (10) LEDs will indicate 
a loop is stored in memory, and may be played at any time. To replay the loop, 
press  the reloop   Button   (8).  The In  B utton  (10) and out  B utton  (10) 
LEDs  will  again  begin  to  flash  indicating  SEAMLESS  LOOP  mode  has  been 
activated and your loop will immediately begin to play.

10. CHANGING  THE TImE  DISPLAY  (53)/TImE  BAR (52):
DURING NORMAL  PLAYBACK, pressing the tIme  Button (2), will change the 
time display information (53) in the lcd (16). The following is a break down of 
the time settings and their definitions:    
1)   REMAIN (48)  -  This  details  the  time  in  the  lcd  (16) as  the  current  tracks’ 
remaining running time.
2)  ELAPSED  (46)    -  This  details  the  time  in  the lcd  (16) as  the  current  tracks’ 
elapsed running time.
3)  TOTAL REMAIN (48) - This details the time in the lcd (16) as the current CD 
total remaining running time (this is for CDs only).
TIME  BAR INDICATOR -  Details  the  time  defined  in  the tIme  meter  (52) as  a  visual  bar  icon.  As  with  the 
tIme  meter  (52) this  bar  is  also  dependent  on  the  selected  time  function [remaIn  (48)  or  elapSed  (46)]. 
This bar will begin to flash when a track is ending regardless  of which time function you are in. Use the flash-
ing bar as a visual reminder that a track is ending.

 PITCH ADJUSTmENTS
©American Audio®   -   www.AmericanAudio.us   -   CK 800Mp3 Instruction Manual Page 22
1. PITCH SLIDER (4):
This  function  will  increase  or  decrease  the  tracks  playback  speed  or  "PITCH." 
The  maximum  pitch  percentage  manipulation  in  this  function  is  +/-100%.  The 
pItch  SlIder  (4)   is  used  to  decrease  or  increase  the  playback  pitch.  If  the 
slider  is  moved  up  (towards  the  top  of  the  unit)  the  pitch  will  decrease,  if  the 
slider  is  moved  down  (towards  the  bottom  of  the  unit)  the  pitch  will  increase. 
The pItch  SlIder adjustment  can  be  changed  to  range  from  +/-4%,  +/-8%, 
or  +/-16%  (See  changing  "PITCH  SLIDER  PERCEnTAGE  RAnGE"  on  the  next 
page).  This  pitch  adjustments  will  effect  normal  playback  and  loops  only  when 
the pItch on/off Button (5) is turned on. 
Figure 21
Figure 23
Figure 22
Using  the  PITCH  SLIDER  (4): Be  sure  the  pitch  function  has  been  acti-
vated  as  described  above.  To  use  the pItch  SlIder  slide  the  slider  up  and 
down. Down will increase the pitch and up will decrease the pitch. 
Activating  the  PITCH  SLIDER  (4): To  activate  the pItch  SlIder  you 
must  turn  on  the  pitch  adjustment  function.  Press  the on/off  Button  (5) 
located  at  the  top  right  of  the  unit.  The  on/off  Button  (5) LED will  glow 
when the function is activated. If the pitch function is not activated the pItch 
SlIder will not function.
PITCH ADJUSTmENTS:
You can activate the pItch SlIder (4) by pressing the pItch on/off Button (5). When the button LED is 
lit, the pItch SlIder is active and the pitch can be adjusted. When the button LED is not lit pItch SlIder is 
not active. The different pitch adjustments allow a track's or a loop's playback speed to be manipulated. This 
speed manipulation is commonly used to beat match between two or more music sources such as a turntable 
or another CD player. The playback speed may be increased or decreased by a factor of +/-16. The next sec-
tion details the different pitch manipulation schemes.

2. PITCH BENDING: 
Unlike the pItch SlIder (4) adjustment this function will momentarily increase or decrease a tracks speed 
during  playback.  There  are  two  ways  to  operate  this  function  with  the  (-)  &  (+)  pItch  Bend  ButtonS  (7) or 
with  the jog Wheel  (9).  The  maximum  pitch  bend  percentage  allowed  is  +/-  16%.  The  pitch  bend  function 
will work in conjunction with the pItch SlIder (4) pitch setting. For example, if the pItch SlIder (4) is set to 
a 2% pitch gain the pitch bending process will begin at 2% and will continue to the maximum of +/- 16%.
Holding  down  or  tapping  on  the (+) 
pItch  Bend  Button (7) will  provide 
a speed bump in the playback pitch.
Holding  down  or  tapping  on  the (-) 
pItch   Bend  B utton (7) will  provide 
a slow down in the playback pitch.
PITCH  BEND BUTTONS (7):
The (+) pItch Bend  Button (7) will increase track playback speed and the (-) pItch Bend  Button (7) will 
decrease track playback speed. The extent to which the speed changes is proportionate to the amount of time 
the button is pressed. For example, if the (+) pItch Bend  Button (7) is held down continuously as in figure 
26, the disc speed will increases and will continue to increase until it reaches a maximum of 16% speed gain. 
When you release the (+) pItch Bend Button (7) the disc speed will automatically return to it’s previous set 
speed.
Figure 24
Adjusting  the PITCH  SLIDER'S  RANGE  (6): You  may  change  the 
pItch SlIder'S  (5) operating  range  at  any  time.  To  change  the  operat-
ing  range  be  sure  the  pitch  function  is  turned  on,  see  figure  33.  The  pitch 
percentage can be changed between +/-4%, +/-8%, and +/-16%. 4% will 
allow the least amount of pitch manipulation and 16% will allow the most 
amount  of  pitch  manipulation.  To  adjust  the  different  ranges,  press  the 
pItch on/off  Button  (5) and  tap  on  the  pItch  range  Button  (6) 
until your desired value is reached, see figure 24.

3. JOG WHEEL  (9):
The jog Wheel will temporarily bend the pitch if a track is in playback mode 
Rotating  the  wheel  in  a  clockwise  direction  will  increase  your  track  pitch  and 
rotating  the  wheel  in  a  counter-clockwise  direction  will  slow  your  track  pitch. 
The  speed  you  rotate  the jog  Wheel  will  determine  pitch  bend  percentage 
(%).  For  example,  if  the jog  Wheel  is  continuously  turned  in  a  counter-
clockwise  direction  the  playback  speed  will  steadily  decrease  and  will  con-
tinue to decrease until playback reaches a maximum of -100% and playback 
stops  entirely.  When  you  stop  turning  the jog  Wheel  the  disc  speed  will 
automatically return to it’s previous set speed.

RELAY (FLIP-FLOP™)
This  feature  is  a  kind  of  “auto  pilot”.  When  you  are  using  the  CK  800Mp3  system,  you  can  have  one  player 
begin playback when the other ends. You can “Flip-Flop™” single tracks, the entire disc, or a combination of 
the two. 
To FLIP-FLOP™ single tracks:
1) Set the mixer's crossfader to the center position, and press the relay Button (23). Also, set both 
2) Set the two players to playback in single mode, SIngle (47) should be indicated in the lcd (16). 
3) Load your two players with audio discs.
4) After they have both cued, press the play/pauSe  Button (11) on one player to begin playback.
5) After the first player’s single track has ended the second player’s track will immediately begin playback.
6) FLIP-FLOP™ will continue until you stop it or power is interrupted.
To Flip-Flop entire CDs: 
Be sure your players are both in continuous play mode, make sure SIngle mode (47) does not appear in the 
lcdS  (16) of  both  players.  Follow  all  directions  for  single  track  FLIP-FLOP™  above.  When  one  player’s  disc 
ends the other player will immediately begin playback.
Note:  You  may  combine  FLIP-FLOP™  single  and  continuously  playback  modes  by  selecting  either  single  or 
continuous playback on your units.

The crossfader is “Hot Swapable” which means it may be replaced at any time, even when power is 
applied. Only replace with American Audio Part Feather Fader Plus. Replacing with any o\
ther model 
fader may seriously damage your mixer.
Replacing the Crossfader:
1.  Disconnect the systems main power supply
2.  Using a Phillips screw driver, unscrew the six stainless steel retainer screws that hold the mixer    
 face plate in place.
3.  Gently remove the channel fader knobs and crossfader knob. Lift the mixer face plate from its to   
 access the crossfader. Carefully pull the crossfader up from its seated position. 
4.  After removing the crossfader, disconnect the ribbon cable that attaches the crossfader to the    
 PC board. Grasp the crossfader by its base and pull the ribbon cable by its connector not the \
   
 actual cables. The connector is designed to only fit one way, so don’t worry about the connec-   
 tors orientation.
5.  Connect the new crossfader to the ribbon cable and replace in reverse order.
