The unit does not work.
Operations are not done properly.

  • One of the unit's safety devices may have been activated.
  1. Press the unit on/off button to the [] position.
    * If the unit does not switch to standby, disconnect the AC mains lead, wait for at least 3 minutes, then reconnect it.
  2. Press the unit on/off button to the [] position. If the unit still cannot be operated, consult the dealer.

A "humming" sound can be heard during playback.

  • An AC mains lead of another device or fluorescent light is near the cables. Turn off other appliances, or keep them away from the cables of this unit.
  • A strong magnetic field near a TV or other device may adversely affect the audio quality. Keep this unit away from such a location.
  • The speakers may output noise when a device nearby is emitting powerful radio waves, such as when a mobile phone is on a call.

No sound.

  • Check the volume of this unit and the connected device.
  • Check connections to speakers and other equipment.
  • Connect speakers and measure the output signal of the amplifier.
  • Check the impedance of the connected speakers.
  • Check to see if the correct input source is selected.
  • Insert the plugs of the cables to be connected all the way in.
  • Confirm the sound output setting. (Sound is not output from the speakers connected to the speaker output terminals of this unit while "PRE OUT" is set to "Off".)
  • Sound is not output from headphones jack and REC OUT/PRE OUT terminals.
  • Playback of multi-channel content is not supported.
  • The digital audio input terminals of this unit can only detect linear PCM signals. For details, refer to the operating instructions of the device.

Video and audio are out of sync when inputting audio signal with video while the digital audio input source (COAX1/COAX2/OPT1/OPT2/PC1/PC2) is selected.

  • Set "LAPC Mode" to "Low Latency". The performance may be improved.
    "Normal": Emphasis on sound quality
    "Low Latency": Emphasis on video/audio synchronisation (Emphasis on low latency)
    The factory default is "Normal".

Cannot start measuring of output correction function (LAPC).

  • Select "LINE1" as input source and then start measuring. While the digital audio input source (COAX1/COAX2/OPT1/OPT2/PC1/PC2) is selected, it may not be measured correctly depending on the status of input signal.
  • Start measuring after exiting menu or setup menu.

The sound is interrupted.

  • The sound from speaker is muted temporarily when you operate Tone Control (On/Off).

Sound is distorted.

  • Setting "Attenuator"/"Gain" to "On" according to the analogue audio input may minimise the sound distortion.
  • When using the high output MC type cartridge, MM setting may be recommended. For details, refer to the operating instructions of the cartridge. If MM setting is recommended, set "MM/MC" to "MM" of analogue audio input (PHONO). It may improve. Also, set "Cartridge Optimiser" again with "MM". However, cannot set to "MM" when using PHONO-XLR cable. When setting to "MM", use the analogue audio cable.

The unit turns to standby mode automatically.

  • Is the auto off function turned on?
  • This unit incorporates a protection circuit to prevent damage caused by heat buildup. When you use this unit at a high volume level for a long period of time, it may turn off automatically. Wait for this unit to cool down before turning on this unit again. (For approximately 3 minutes)

The settings are reset to the factory defaults.

  • Updating the firmware may reset the settings.
