Connecting audio equipment

The following illustrations show how to connect a CD player, MD recorder, etc. using both analog and digital connections.
However, it's not necessary to make both connections.

Audio connections

● Be careful not to mix up the left and right connections.
● [AP-U70 only]
If you wish to record analog sound signals inputted
to this unit, connect the analog inputs of a tape deck
or MD recorder to this unit's REC OUT OUTPUT.

A turntable cannot be connected to this unit directly. Use a
commercially available phono equalizer amplifier to connect a
turntable to this unit, or connect a turntable incorporated with a
phono equalizer amplifier.
● [AP-U70 only]
The REC OUT OUTPUT and DIGITAL OPT OUT can
be used at the same time since they output signals
independently.

Notes
● When playing an ordinary CD on this unit following
playback of a CD or an LD encoded with DTS, some
operations, such as resetting the input selector keys, may be
required.
● Even if connected to this unit with a digital connection, some
CD, LD, and DVD players may make this unit fail to decode
DTS or produce noise. This is because certain digital output
data processing by such a player results in DTS-encoded data
errors that cause playback failure although the same data
processing may cause only a slight change in volume or in
frequency response in normal digital sound.
● When an error occurs in the player's digital output data
during playback of an LD or CD encoded with DTS,
playback may be disrupted. If this occurs, stop playback and
repower the player.
● When digital sound signals from the computer are played,
errors in WAVE signals, etc. may occur resulting in noise or a
playback failure.
