3.1.3
Treble
Set a global or individual treble level between – 7 dB and + 7 dB.
3.1.4
Loudness (Contour)
If you listen to music at low levels, you often recognize that bass and treble reproduction are weak.
This is because the human ear is not sensitive to bass and treble at low sound levels. To compensate
this you can use the parametric loudness function of the C 5.2. This function will increase bass and
treble levels when you decrease the volume. When the volume is increased the frequency response will
be more and more flat and remain linear at high volume levels. In order to obtain best results you have
to proceed in the following way:
Set the amplifier to a moderate volume level. Using the
VALUE
buttons (8, 9) choose in the loudness
menu a curve ("of" and 1 to 9) which gives best sound impression and exit the menu (button
EXIT
(7)).
NOTE
: The loudness function selects automatically the correct curve depending on actual volume
setting. So if you change volume a different curve than previously selected may be shown in the
loudness menu. This is not a malfunction.
3.1.5
Balance
Set the balance between right and left channel for optimal stereo image.
3.1.6
Poweramp
In order to enable or disable both switchable speaker terminals (15, 28), you can set the poweramp ON
or OFF. This can useful if you have connected a headphone amp or a separate power amplifier to the
pre out (21). The chosen setting is saved permanently and can be changed again by new call of the
menu.

Tuner settings
3.2.1
RDS display
Choose if station NAME, RDS-TEXT or FREQUENCY is displayed.
3.2.2
Scan mode
Set tuning mode between "auto" or "manual" (see also 2.5.1).
3.2.3
2 channel mode
Set tuner to mono or stereo to obtain best sound.
NOTE
: Depending on actual setting the threshold for auto tuning will change (sensitive in MONO, less
sensitive in STEREO).
3.2.4
Deemphasis
Depending on the country in which you will be using your device, setting a corresponding deemphasis
value helps to improve the sound quality by optimizing the signal-to-noise ratio and transmission
behavior of your FM tuner. Please choose the option"EUR, AUS, JPN", unless the unit is being used
the United States of America (USA).
