3.1.3 Treble

Set a global or individual treble level between – 7 dB and + 7 dB.

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.

Set the balance between right and left channel for optimal stereo image.

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.

Choose if station NAME, RDS-TEXT or FREQUENCY is displayed.

Set tuning mode between "auto" or "manual" (see also 2.5.1).

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).

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).
