LISTENING MODE

The C 390DD oers distinct listening modes, tailored for dierent types
of recording or program material. The following listening modes can be
selected.
STEREO
• Select “Stereo” when you wish to listen to a stereo production, such as
music CD or FM broadcast.
• Stereo recordings whether in PCM/digital or analog form and whether
surround-encoded or not encoded, are reproduced as recorded.
• Multi-channel digital recordings (Dolby Digital and DTS) are reproduced
in “Stereo Downmix” mode via the left and right speakers only.
MONO
• Use “Mono” listening mode when the audio source format is mono. The
mono information is replicated on both left and right channels.
• Mono” listening mode is recommended when watching old movies
with mono soundtrack, listening to recorded monaural sound sources
such as AM radio broadcasts or with the foreign language soundtracks
recorded in the left and right channels of some movies.
• Mono is also very helpful when setting up a stereo system to check that
both speakers are connected with correct polarity. Correctly connected
speakers will have a solid center image and strong bass response. If one
speaker has the input connections (+ and -) reversed, the image will be
indistinct and the bass will be reduced and uneven sounding.
REVERSED
• Sends the right channel to the left speaker and the left channel to the
right speaker. This can easily correct a reversed input connection or
incorrectly recorded music source.

Digital impedance compensation lter allows ne tuning of the top
octave to match the speaker impedance. This will result in perfectly at
frequency response at 20 kHz. The eect of this lter may not be audible*
but it is measurable, and it compensates for the small eect of the digital
reconstruction lter that eliminates the 844 kHz sampling frequency of the
amplier.
*The exception may be some electrostatic speakers that have very low
impedance at high frequency. The lower the HF impedance, the greater the
deviation from at response.

Set the assignment of the rear panel output port PRE OUT/SUBW to either
PRE OUT or SUBWOOFER. If PRE OUT is selected and enabled, SUBWOOFER
is automatically disabled and vice-versa.
