  hi all,
  
  I noticed a weird sound in the left channel (channel 1) of eclipse output (sounded a bit like a mobile phone about when calling)..
  
  It has disappeared, but now channel 1 output is much quieter than channel 2, if i set output gains : +10db for channel 1 and -10db for channel 2 ,this seems to correct the inbalance, and sounds fine..
  
  I have checked leads etc, and all fine
  
  My in mode is mono 1
  
  any ideas what may have happened?

  -which OS is the unit running on?
  
  -on which preset you noticed the "mobile phone" sound and the leel difference between channels?
  
  -how the Eclipse is connected(type of cables/plugs/wiring) and to what?
  
  -what type of signal is fed to it?

  hi italo,
  
  -I have just upgraded the unit to 3.5b from 3.1 to see if that would help, but the level difference remains..
  
  -I can't remember what preset i noticed it on, most likely stringroom2
  
  -Eclipse is connected to a mackie mixer – TRS from the mackie to XLR into the eclipse
  
  -signal in is an aux send from the mackie, my main channel on the mackie is an acoustic guitar–>lrbaggsparadi—>barber compressor—>line6effects
  
  I have just returned from a festival, before which the eclipse was working fine..
  
  There was a power cut during my set (the stage was run from a generator charging batteries), I over ran a bit and the batteries ran out! I'm not sure if this is a variable, i have a surge-protected power 6-way which the eclipse plugs into..
  
  Perhaps the eclipse has been knocked or vibrated during transit and so this is a hardware issue?

  ps the level difference is also present when the unit is in bypass

  Hi Dan
  
  I'm afraid the unit has a hardware problem. Power surges or instabilities of +/- 10/12% of the nominal voltage may be fatal to digital equipment. You may try reinitializing the unit, either with a CLEAR SETUP (doesn't erase your presets) or a FULL REINIT (kills your stuff!) and check if it helps.
  
  Power w/SETUP key pressed & held for clear setup & follow screen instructions.
  
  Power w/8 key pressed & held for full renit & follow screen instructions.
  
  Please let me know!

  Also, make sure that ALL pins of the XLRs are connected – it may be that you are connecting to an unbalanced line, without unbalancing the XLR properly.
  
  Simple test – reverse the L/R connections at both input and output and see if the problem changes side – if it does, it's a cabling issue.

  hi guys,
  
  have tried a full reset, and checked the leads, swapped sides – problem is still there – the left being quieter…
  
  Ok, so if we assume it is a hardware issue, which I think it must be, then it needs to be repaired,
  
  Is it possible to have this done in the UK?
  
  And also what power protection should i be taking out live to stop this happening again? I play venues of all types, hi-spec and low spec, and i bought the eclipse to take out with me! Road warrior! 🙂

  You can try to contact U.K. distributor, HHB:

  A power stabilizer with surge protection would keep all your digital gear safe on stage, when power fluctuates like crazy.
  
  all the best

  hi italo,
  
  thanks i will contact them…
  
  I did look at line conditioners etc a while back now i think of it, do you know of any good voltage-regulating units that are not 19" rack? I have a 2u rack which i can't really expand due to what i can carry to gigs..

  I have no advice fornon_rack units, unless you want to look into computers line conditioners and backup units. I use Online, a german brand that has proved full reliability on me, but these devices may be not the most portable solution.
