TROUBLE-SHOOTING GUIDE – some of the most common problems

No sound:

  • Power turned off or system in standby mode. Check that the LED in the STANDBY button is green/blue.
  • The input connection is loose or missing. Check that the connection is secure.
  • Protection relay has operated because of a short circuit loudspeaker wire or amplifier overheating. Carefully check all wiring after switching the amplifier POWER OFF to allow it to cool.
  • The fuse in the power cord inlet has failed. Unplug the power cord from both the wall socket and the amplifier and pull out the small receptacle below the power cord inlet. Two fuses should be visible. The further fuse is the operative one and should be checked. If it has failed, replace it with the nearer (spare) fuse. If this too fails, then return the amplifier to your dealer for service.
  • UK version only: The fuse in the mains plug has failed. Check and replace if necessary.

    Sound in one channel only:

  • Loudspeaker cable pulled loose. Check all connections, both at the loudspeakers and amplifier.
  • Interconnect cable pulled loose or making poor contact. Check and, if necessary, un-plug and re-plug all relevant cables.

    Unit fails to respond to My Link remote commands (from e.g. MP 100 Preamplifier):

  • My-Link cable is loose or not connected. Check connections on all linked units.

    Loud buzz or hum:

  • Interconnect cable pulled partially out of its socket.
  • Defective interconnect cable.

    Incorrect operation – some functions not working:

  • Control processor latched. Switch off POWER on rear panel and wait for about one minute. Then switch POWER on. Normal operation should resume.

    Hum in tape playback:

  • Tape deck too close to the amplifier (e.g. directly above or below).
  • Plugs making poor contact with sockets.

    Disc does not PLAY:

  • No CD is inserted. Insert a CD, label side up.
  • The CD has been loaded upside down. Re-load the disc label side up.
  • The CD is badly scratched or dirty. Check the CD and clean or replace as necessary. The CD skips part of the music.
  • The CD is badly scratched or dirty. Check the CD and clean or replace as necessary.
