  INTRODUCTION
  U NpAC kIN g
Every  Radius  3000™  has  been  thoroughly  tested  and  has  been  shipped  in  perfect  operating  condi-
tion.  Carefully  check  the  shipping  carton  for  damage  that  may  have  occurred  during  shipping.  If  the 
carton  appears  to  be  damaged,  carefully  inspect  your  player  for  any  damage  and  be  sure  all  equip-
ment necessary to operate the player has arrived intact. In the event damage has been found or parts 
are missing, please contact our toll free customer support number for further instructions. Please do 
not return the player to your dealer without first contacting customer support.
Please be sure to make any connections before plugging the player in to an electrical outlet. All fader 
and volume controls should be set to zero or minimum position, before the player is switched on. If the 
player  has  been  exposed  to  drastic  temperature  fluctuation  (e.g.  after  transportation),  do  not  switch 
on  the  player  immediately.  The  arising  condensation  of  water  might  damage  your  device.  Leave  the 
device switched off until it has reached room temperature.
Operating Determinations:
•  When installing this player, please make sure that the device is not exposed or will not be ex-   
 posed to extreme heat, moisture or dust!
• Do not operate the player in extremely hot (more than 30°/100°F) or extremely cold (less than    
 5°C/40°F) surroundings. 
• Keep the unit out of direct sunlight and away from heaters.
• Operate the player only after becoming familiar with its' functions. Do \
not permit operation by    
 persons not qualified for operating the unit. Most damages are the result of unprofessional opera-  
 tion.
  SET -Up  pRECAUTIONS
©American Audio®   -   www.AmericanAudio.us   -   Radius 3000™ Instruction Manual Page 6 
						

							
(a)  fADER “Q” START CONTROL: This feature is used in conjunction with most American Audio® and American 
 DJ® audio mixers that also feature “Fader Q Start” control. For best results use this feature with two (2) Radius   
 2000 players. Connect your Radius 3000 as described in the set-up section of this manual. After set up is com- 
 pleted load your players. By moving the mixer’s crossfader from left to right you can start and pause your Radius   
 2000 playback functions. For Example, when using two (2) Radius 3000™ players and a Fader “Q” Start mixer, if   
 your mixer’s crossfader is all the way to the left (player one is playing, player two is in cue or pause mode), and you   
 move the fader at least 20% to the right, player two (2) will begin to play. When the crossfader ismoved all the way   
 to the right, player one (1) will return to cue mode, and you move it 20% to the left, player one (1) will begin to play 
 and player two (2) will return to its’ cue point. You can create great effects similar to scratching with this feature.   
 After storing cue points on each side of the player, different songs or samples may quickly be recalled by moving   
 the mixer crossfader back and forth. New cue points can be easily selected on the Radius 3000 player (see setting   
 cue points page 20). “Q” Start control is easy to use and mastering this feature will help you create amazing effects   
 with your music. Note: For proper “Q” Start operation be sure your mixers “Hamster” setting are set to 1/2 (Normal   
 Setting). Important: When Bank Button LED is flashing, the unit will return to the bank in point.
(b)  fLIp-fLOp: This feature is used in conjunction with American Audio® mixers that also feature Fader “Q” Start. For
   FLIP-FLOP results you must use two (2) Radius 3000 players. Connect your Radius 3000’s as described in the   
 set- up section of this manual. This feature will start the next player once one (1) player has ended. For example, if   
 player one (1) is playing a disc in the single mode and it ends, player one (1) will pause, player two (2) will instantly   
 begin to play. You may set FLIP-FLOP to play track to track. For more information on this feature, see FLIP-FLOP™   
 on page 40. Important: When Bank Button LED is flashing, the unit will return to the bank in point.
(c) mEmOR Y BACkUp: The Radius 3000™ has a five (5) year memory back-up, that will save your setting in case   
 the  power supply is accidentally disconnected. Radius 3000™ will remember your last setting (SGL, CTN, and 
  effect parameters) even if you disconnect your main power. The Radius 3000™ will store your cue points and   
 samples in memory if you accidentally eject a disc or shut off the power. See memory on page 26.
(d) pROgRAmmABLE CUE  pOINTS: The Radius 3000™ has four Bank ButtonS (28). 4 cue points can be stored
 per folder for SD/USB audio device, with a total of 500 Cue points being stored in each of the Bank ButtonS   
 (28), a CD can store a total of 2000. These cue points can be stored into the unit's internal memory and may be   
 recalled at any time. See setting "Cue Points" on page 20.
(e)  SLEEp  mODE: The Radius 3000's laser and pick-up assembly will power down after 15 minutes of inactivity (when   
 in pause or cue mode). This will lengthen the life of your motor drive and laser. To initialize the player press cue or   
 play button.

even  if  a  disc  has  been  removed  and  will  reflect  on  any  other  disc  loaded  into  the  player.  That  is  to 
say, if you set a +2% pitch on one disc, remove that disc and load another, that disc too will have a 
+2% pitch. The amount of pitch being applied will be displayed in the Vfd (3).

The  pitch  percentage  can  be  changed  between  4%,  8%,  16%  and  100%.  4%  will  allow  the  least 
amount of pitch manipulation and 100% will allow the most amount of pitch manipulation. To adjust

9. JOg WHEEL/EffECTS  pLATTER - This wheel has three functions;
A. The jog wheel will act as a frame search control when the track is in pause or cue mode, allow- 
 ing you to set a cue point. 
B. The wheel also works as a pitch bend during playback. Turning the wheel clockwise will increase 
 the pitch percentage up to 100%, and turning the wheel in the counter-clock  wise direction will  
 decrease the pitch percentage down to -100%. The pitch bend will be determined on how long   
 you turn the jog wheel continuously.
C. The jog wheel can also be used in conjunction with the time (31) and ratio (25) knobs to adjust   
 and set effect and sample parameters, see page 24.
The  Jog  Wheel  light  ring  can  also  be  adjusted  to  run  differently.  To  change  the  light  ring  you  must 
enter the Internal Menu, see page 17. Locate JOG MODE in the menu. The differnet functions are as 
follows:
1 (Mode 1) - Value 1-32; this will make your playing point indicator smaller at value 1 or a full circle   
    at value 32.
2 (Mode 2) - This is similar to mode one but will turn the lit portion of the playing indicator off when   
    the  touch sensor on the jog wheel is touched.
3 (Mode 3) - Will show your playing marker rotating while the rest of the wheel is lit but at a dimmer   
    level.
