TROUBLESHOOTING
Power LED/knob LEDs do not illuminate when power switch is turned on.
• FireWire port is not supplying enough power for ERGO. Use the 12VDC power adapter to power up  
  ERGO.
• Is power switch REALLY turned on? Check it again while using the external adapter.
• Is the AC outlet working?
 
ERGO Cal software does not run.
• Driver is not installed properly
• ERGO is not plugged into a FireWire port
• Power is not applied to ERGO 
 
Microphone does not work.
• You need to have the Calibrate switch on the back of ERGO pushed in in order for the mic to work.  
  Make sure  the calibrate LED on the front panel is illuminated.
• USE ONLY THE KRK MIC! Don't plug in any other mic for calibration. If you lose your KRK mic, you can 
  buy a new one from KRK customer support at 954.316.1580.
• Check the ERGO control panel to ensure that the mic is turned up.
 
ERGO Cal software asks for lots of measurements.
• That's OK. It can take between 3 and 9 measurements before you get to 90% or greater Room     
  Knowledge.
 
Room Knowledge never gets to 100%.
• Some things in life cannot be fully understood—like your spouse. So, your room may be another
  one of these things. As long as Room Knowledge is 90% or greater, your mixes will sound better.
I don't hear a difference between ERGO in bypass and processing modes.
Your room may already be very good, so ERGO isn't doing much. This is very unlikely, however. ERGO's 
effects can range from subtle to extreme, so there should be a difference. In particular, listen for the      
following:
• Improved imaging • Tighter bass • More definition among instruments
ERGO's goal is not to make the mix “sweeter” but to make it more accurate. If you don't think you are 
hearing something, finish the mix and see how it translates to other environments. This is proof that 
ERGO  is  working.  If  you  are  still  not  hearing  what  you  believe  is  an  accurate  mix,  you  may  have 
problems with:
• Your monitors—get a pair of KRK monitors!
• Your ears—Cotton swabs are relatively inexpensive, and can perform wonders.
• Your brain—please refrain from mind altering substances when using and/or evaluating ERGO. Your
  auditory faculties and the processing thereof will be greatly enhanced. Also, visit the ERGO forum
  and talk to us! We can help! Go to www.krkergo.com and click the Forum link.
The calibration mic level is not loud enough.
• Turn up the volume on your speakers. The speakers need to excite your room in order for ERGO to     
  measure it accurately.
• Turn up the volume on ERGO. The volume control should point to the word Volume. This is the 0dB 
  point for the volume control.
• Turn up mic volume on the control panel. Normally, ERGO handles this gain stage, but if your 
  speakers are on the weak side, turning this up manually can help.
I installed ERGO as a FireWire device, and now my other XYZ FireWire interface is gone.
This should not happen on Macs, since the Mac OS can aggregate, or combine, multiple devices into a 
single interface. Windows users have a couple of options:
• Windows systems can only have a single ASIO device. Use your main ASIO device when tracking, 
  and switch to ERGO ASIO when mixing down.
• Take a SPDIF or analog out from your existing FireWire interface and plug it into ERGO. In this mode, 
  you can unplug ERGO from its FireWire port and power up using the external power adapter. ERGO's   
  SPDIF inputs and converters are of the highest quality, so there will be no degradation when using 
  this approach. In fact, if your DAW is “dialed in”, we suggest that you use this approach. Also, this is 
  the  only approach to use for Pro Tools rigs.
• Use the WDM drivers. Windows can aggregate WDM devices. Latency may increase when using 
  WDM instead of ASIO.
Using a Mac, I cannot see ERGO as a FireWire device.
• ERGO needs Leopard (10.5.x) or later. Check www.krkergo.com for detailed instructions on how to  
  enable work-arounds for other OS versions. 
ERGO Rocks! But I want to mix in surround. Can I use 2 or more ERGOs for this?
• No. Surround has other issues. Keep checking www.krkergo.com for exciting ERGO developments.
BEFORE YOU START... GET TO KNOW ERGO
STATUS LEDs
Clip – Lights when the incoming analog signal (Input L/R, Cal Mic) is overloading the system and is 
clipped.
IO / FireWire – LED is red when power is applied and ERGO is turned On. LED is green to indicate that 
ERGO has established a link to your computer via FireWire.
Calibrate – When the Calibrate pushbutton at the rear panel is depressed, this LED lights. This indicates 
that ERGO is in calibration mode (this is to be used with your measurement mic).  The IO / FireWire LED 
must be green to perform calibration.
VOLUME KNOB
Controls the level of monitor outputs (A, B/Sub).
BUTTONS
A  –  Controls  the “A”  speaker  outputs.  When  lit,  the  A  speakers  are  active.  When  unlit,  they  are 
muted/deselected.
B/Sub  –  Controls  the “B”  speaker  outputs. When  lit,  the  B  speakers  are  active. When  unlit,  they  are 
muted/deselected.
Special Note:
  The software control panel selects the speaker mode. In default (non-subwoofer) mode, 
only the A or B speaker can be selected. ERGO is smart enough to make the A/B buttons mutually 
exclusive. Using ERGO's control panel, it is possible to set ERGO up in subwoofer mode. In subwoofer 
mode,  ERGO  makes  the  A/B  buttons  independent,  so  that  you  can  mute  or  enable  the  sub  in               
conjunction with the A speakers.
Focus/Global – ERGO has two modes of operation—focus and global.  In focus mode all of ERGO's 
processing  power  is  correcting  the  focus  (sweet  spot)  position.  Use  this  mode  when  mixing  your 
tracks.  In  global  mode,  ERGO's  processing  power  is  correcting  a  much  larger  area,  though  not  as 
accurately as when in focus mode. Use this when you want an audience to hear the corrected 
room.
When the Focus/Global button is depressed for two seconds, ERGO enters bypass mode (indicated by 
the  LED  flashing).    In  this  mode,  audio  is  passing  straight  through  with  no  correction  being   
performed.
