Possible cause and solutions

• Are device connections and PHONO or external output terminal connections correct?
  Connect the PHONO output terminals with the amplifier’s PHONO input terminals.
  Connect the external output terminals to the amplifier’s external input terminals.
• Are both PHONO output terminal and external output terminal simultaneously connected to the device?
  Connect one or the other.
• s the external output switch correctly set?
  When connecting the external output terminals, set the external output switch to "ON".

Model SL-C700

Possible cause and solutions

• Check the volume of the connected device (amplifier, etc.).
• Check to see if the cable connections to the input and output terminals are incorrect. If incorrect, turn off this unit and reconnect the cables correctly.
• Check to see if the correct input source is selected.
• Make sure that the plugs of the cables are pushed (connected) all the way in.
• When “Digital Output”, “Analog Output” or “Digital Link” is set to “Off”, no sound will be output. Change the setting of the output terminal in the setup menu to be used to “On”.
