Connecting audio
components

Connecting a turntable

Be sure to match the color of the plugs and
the connectors. To listen to the sound from
the connected turntable, press FUNCTION
repeatedly until “PHONO” appears.

Note

Using the turntable at high volume may cause
distortion or howling. This is often caused by the
bass sound from the speakers. The bass sound may
be picked up by the needle of the turntable, and
produce the distortion or howling. To avoid this, do
the following:
1

Keep some distance between the speakers and the
turntable.

2

Stop using the surround effect.

3

Install the speakers or the turntable on a firm and
stable surface.

4

Press DBFB repeatedly until “DBFB
