÷ It is not favorable for the sound quality to decrease the output level from
this unit too much. Use these keys for coordination with other line
levels.
÷ Adjusting the headphone output level also changes the LINE/OUT
level. Do not adjust the output level from this unit particularly during
recording.
Connection to a general-use amplifier
Use the provided audio cords to connect the OUTPUT jacks of this
unit to the CD input jacks (or AUX jacks) of the amplifier.
Connection to digital amplifier or MD
Connect the DIGITAL OUTPUT (OPTICAL or COAXIAL) jack to the
digital input jack of the amplifier, DAT recorder, MD recorder, etc.,
using an optical fiber cable or coaxial cable which are commercially
available in audio stores.
÷ When using an optical fiber cable to connect this unit to a digital
amplifier, insert the plug straight into the jack until a snap sound is
heard.
÷ Be careful not to bend, coil, or bundle the optical fiber cable.
÷ Optical fiber cables available on the market may not always be able to
be used with this player. If your cord cannot be used with this unit,
consult the store from which you purchased the cord or your nearest
dealer.
