Trouble Shooting

Trouble Shooting

• Do a line check first go through everything and
  if something isnt working make note of it and
  come back to it, this way you have an idea of how
  long you have to trouble
• keep channels that arent working muted.

No input to Channel Strip

• Think Linear
• Start at one end or the other of the signal path
  never in the middle.
• Start at the source and work your way back toward
  the console or from the console back to the
  source
• Most common problem areas are XLR Lines, snake
  channels sometimes microphones and input channels
  on the console
• Check to make sure phantom power is on if
  required
• Is something inserted on that channel? i.e. Gate?
  If so, unplug or disengage it from the channel.

No input to Channel Strip

• Check Patch Starting at one end (be careful about
  numbers 6 and 9 when patching)
• By Pass sub snakes and go directly into main
  snake
• Try a different channel into the snake, one that
  has already been tested and you know works
• Directly into console (If you think it might be
  the microphone)
• Try a different XLR cable

No input to Channel Strip

• Check ¼ patch cables from instruments
• Could also be the output jack from the instrument
  
• Bad DI? Unplug it and check the line with a
  microphone

No Output to Speakers

• Panic!! Yell at people!! Start freaking out!!!
• Be Calm
• Check Master outputs for signal, make sure
  masters are turned up
• Check for signal to eq and compressors
• Check for things that could be muted i.e.
  crossovers, processors.
• Are the amps turned up?
• Check Patch think
• What is the weakest link?
