3) Select the filter type with the rotary knob
PM3. A change is effective immediately.
The following filter types are available:
Ƅ Peaking_Eq
(Peaking Equalizer)
filter with bell characteristic with adjustable
gain / attenuation, mid-frequency and quality
factor
ƃ Hi-Shelv_1
(High Shelving Filter 1)
high frequency filter of first order with shelv-
ing characteristic
The level at the adjustable cut-off frequency
is 3 dB below/above the adjusted gain/atten-
uation; the slope is 6 dB / octave.
ƃ Hi-Shelv_2
(High Shelving Filter 2)
high frequency filter of second order with
shelving characteristic
The level at the adjustable cut-off frequency
is 3 dB below/ above the adjusted gain/atten-
uation; the slope is 12 dB / octave.
ƃ Hi-Shelv_Q
(High Shelving Filter Q)
symmetric high frequency filter with shelving
characteristic.
The level at the adjustable cut-off frequency is
half of the adjusted gain / attenuation; the
slope depends on the adjustable quality factor
Ƃ Lo-Shelv_1
(Low Shelving Filter 1)
low frequency filter of first order with shelving
characteristic
The level at the adjustable cut-off frequency
is 3 dB below/above the adjusted gain/atten-
uation; the slope is 6 dB / octave.

Ƅ Band Pass
band pass filter with a passband around the
adjustable frequency. The bandwidth is
defined by the adjustable quality factor.

5.3.4.3 Changing filter parameters

1) Select an input with its button (10).
2) Use the rotary knob NAV/ PM1 to select the
desired filter (
with the button ENTER. The present adjust-
ment is shown, e. g.
Input-A
ƊByp=Off Type=Peaking_Eq
3) Press the button ENTER. The present filter
parameters are now shown, e. g.
Ɗ 1000Hz
i. e. mid-frequency = 1000 Hz,
gain = 11.5 dB, filter quality factor = 1.1
Note: The availability of a parameter depends
on the filter type selected.

4) Adjust the frequency with the rotary knob
NAV/ PM1. A change is effective immediately.
For faster frequency changes, press the but-
ton ENTER. The lower line of the display now
shows e. g.:
ƊEdit Frequ = 1000Hz
The frequency can now purposefully be
changed with the rotary knobs NAV/ PM1 in
steps of 1000 Hz, PM2 in steps of 100 Hz and
PM3 in steps of 1 Hz. To return to the higher
menu level, press the button ESC.
5) Adjust the gain / attenuation with the rotary
knob PM2.
6) Adjust the filter quality factor with the rotary
knob PM3. A change is effective immediately.
To return to the next higher menu level, press
the button ESC. To exit the adjusting menu,
press the button ESC repeatedly or deselect the
input selected first.

5.4 Configuring outputs

The signals of all outputs run through the pro-
cessing chain shown in fig. 6.
5.4.1 Muting the output and

selecting it for the adjustment

Each output can both be muted and selected for
the change of adjustments with the button (10)
below its level indication.
Press button for a while (approx. 2 s):
The output is muted or the sound is reacti-
vated. With the output muted, the LED MUTE
(8) lights up. When a new model configura-
tion is selected or the present model configu-
ration is reset via the function "System Setup"
( chapter 5.2.1), all outputs are muted as a
precaution for the time being. The required
outputs have to be switched on again, as
described here.
Press button shortly:
The output is selected or deselected. If the
output is selected, the LED EDIT (9) lights up.
To make adjustments for several outputs
together, further outputs can be selected in
addition to the output already selected.
These outputs can be deselected again. If the
first output selected is deselected, all outputs
are deselected. Only the
changed during linking are adapted. All indi-
vidual adjustments of the outputs are main-
tained.
When selecting an output, the display (1) shows
the last menu item called for this output in the
menu of the output adjustments (
menu items are selected and the adjustments
are changed with the rotary knobs NAV/ PM1 (2),
PM2 (3) and PM3 (7) and the buttons ENTER (4)
and ESC (5).

5.4.2 Changing the name

After selecting a model configuration via the
function "System Setup" ( chapter 5.2.1), the
outputs are named according to their function
provided in it. These names can be changed,
e. g. to indicate the place of the speakers.
1) Select an output with its button (10).
