Tone Control Menu
The decoder features an active tone control system
(+/- 6 dB) whose purpose is to compensate for the un-
wanted influence on playback quality of your listening
room, or of imperfect loudspeaker positions.
The treble / bass balance can be adjusted separately for
all the output channels, and can therefore compensate
for problems caused by the location of individual speak-
ers.
The first step is to select a sound source which you wish
to use as the basis for adjusting the tone controls. Make
sure that the sound source you choose is active on all
the channels, so that the sound image is typical of your
listening habits, and any changes you make to the tone
controls are immediately audible in that setting.
Once you have activated this section of the menu, you
will find the data input position after the first menu point.
'FL TB: 00
'
.
You can now alter the value within the range
–06
to
+06
using the change buttons; any change you make is
immediately audible.
Select the input position using the select buttons.
As the illustration shows, you can cycle through the input
positions in the following order:
Output channels not in use (see
'

Set values for treble
(TB)
and bass
(BS)
on all channels
which gives as well-balanced a sound image as possible.
Note:
Adjusting the tone controls has an influence on the over-
all level of that channel. After making a change here we
recommend that you call up the
'
Speaker Balance
Setup
'
again so that you can check the balance of all
channels and make corrections if necessary.
