  • Page 8: Earthing

    Earthing The connection to earth (ground) in an audio system is important for two reasons: SAFETY - To protect the operator from high voltage electric shock, and AUDIO PERFORMANCE - To minimise the effect of earth (ground) loops which result in audible hum and buzz, and to shield the audio signals from interference.

  • Page 9: Cables And Connections

    Cables and Connections The XONE:02 uses professional grade 3 pin XLR, 1/4" TRS jack and RCA PHONO sockets. The following mating plugs may be used: The XLR connector is 3 wire balanced. This has 3 connector pins: Pin 1 = ground (screen), Pin 2 = signal hot (+), Pin 3 = signal cold (-).

  • Page 10: Gain And Operating Levels

    Gain and Operating Levels It is most important that the system gain and level settings are correctly set. It is well known that many DJs push the gain to maximum with meters peaking hard in the belief that they are getting the best from the system. THIS IS NOT THE CASE ! The best can only be achieved if the system levels are set within the normal operating range and not allowed to peak.

  • Page 11: Replacing The Faders

    Replacing the Faders The faders on a DJ mixer are heavily used and can suffer considerable wear and tear. The audio design using VCAs prevents clicks and scratchiness as the fader wears. However, the movement can become mechanically stiff or sloppy in time, or become ingrained with dirt.
