Troubleshooting
If you experience any problems with the unit, please take a moment 
to  look  through  this  chart  and  see  if  you  can  solve  the  problem 
yourself  before  you  call  your  dealer  or  ESOTERIC  customer  service/
technical support.
Moreover, the problem might be caused by something other than this 
unit. Confirm that connected devices are also being used properly.
General
No power.
e Check  the  connection  to  the  AC  power  source.  Check  and 
make sure the AC source is not a switched outlet and if it is, the 
switch is turned on. Make sure there is power to the AC outlet by 
plugging another item such as a lamp or a fan.
Remote control does not work.
e If the batteries are exhausted, change the batteries.
e Use  the  remote  control  unit  within  the  effective  range 
(7 m/23 feet) and point it toward the remote sensor on the front 
panel.
e Make  sure  that  there  are  no  obstacles  between  the  remote 
control unit and the main unit.
e If a fluorescent light is near the unit, turn it off.
Buttons do not work properly.
e If  another  operation  is  still  in  process,  wait  a  moment  and  try 
again. 
Other units with remote controls operate incorrectly.
e Note  that  other  units  with  remote  controls  may  operate 
incorrectly because of infrared light “overspill” when you operate 
the remote control of this unit. 
Severe hum or noise is heard.
e Place the unit as far away from a TV as possible.
There is no sound or only a very low-level sound is heard.
e Adjust the volume by pressing the VOL (+/−) buttons.
e Check  that  the  speakers  and  components  are  connected 
securely.
e Check the operation of the connected component.
e There  might  be  a  +/_  short  in  a  speaker  cable.  Check  the 
speaker cables.
e Select the proper input source using the SOURCE button.
There is no sound from a connected digital device.
e When connecting the digital output terminal of a DVD player or 
other digital device, set the digital audio output of the connected 
device  to  PCM.  You  can  also  connect  the  analog  outputs  of  a 
digital device to this unit’s analog inputs (LINE IN).
The display shows “AMP ERROR!”.
e See “Protection Circuit” on previous page.
CD/Super Audio CD Player
Will not play.
e Press the SOURCE button repeatedly to select “CD/SACD”.
e Reload  the  disc  with  the  label  side  up.  If  not,  insert  the  disc 
correctly.
e If  the  disc  is  dirty,  clean  the  surface  of  the  disc.  If  the  disc  is 
scratched or has any sticky substance on it's surface, do not play 
the disc until you have corrected the condition of the disc. Under 
all circumstances, do not use after market stick on labels or “disc 
enhancement” devices that sit on top of a disc or wrap around a 
disc.
e If the unit has become condensed with moisture, leave the unit 
for one or two hours with the power turned on.
e The  multi-channel  area  of  a  Super  Audio  CD  cannot  be  played 
with this unit. This unit is a 2 channel player only.
Noticeable difference in CD and Super Audio CD’s volume.
e That is because CDs and Super Audio CDs use different recording 
methods. This is normal.
USB connections with personal computers
This unit is not recognized by personal computers.
e USB  connections  are  possible  with  personal  computers  running 
with Microsoft Windows XP or Windows Vista. Other operating 
systems  are  not  guaranteed  but  may  operate.  This  unit  might 
not  function  properly  when  used  with  a  computer  running  a 
different  OS.  In  addition,  the  connected  computer  should  be 
compatible with USB 1.1 or higher.
Noise occurs.
e Starting  other  applications  during  playback  of  a  music  file  may 
interrupt playback or cause noise. Do not start other applications 
during playback. 
Music files cannot be played.
e Connect  this  unit  to  the  personal  computer  before  launching 
music  playback  software  and  starting  playback.  If  the  music 
playback software is launched or the input of this unit is switched 
to “USB” before this unit is connected to the personal computer, 
music data may not be played back correctly.
e Check the points on page 20 - 21.
Sound is too low.
e Confirm that the volume settings of the music playback software 
and the operating system are not low. Turn up the output volume 
on the PC as needed.
Since this device uses a microcontroller, external noise and 
other interference can cause the unit to malfunction. If this 
occurs, turn the power off and restart operations after waiting 
for about one minute.
