menu 

 – from this sub-menu it is possible to set the Input  Channels 5 available

Peaking or Shelving Filters.

The CLP2600 allows the user to select either Peaking or Shelving Parameters and assign them
independently using the 5 available filters.

In order to select the filter

'

s type

,

it is necessary to have the filter

'

s GAIN

=

0

.

0dB

,

then using the

PM2 encoder

,

rotate it

clockwise

in order to decide the Peaking filter

'

s Bandwidth

,

or 

counter

-

clockwise

to select the Shelving filter type

(

Low or High

)

and its order

(

1

st

 or 2

nd

 ).

So

,

in order to define the filter type for the filter number 1

(

x

=

1

),

it is necessary from the above

screen

,

to enter the filter

'

s editing page pressing the ENTER button

,

and the screen has to appear

as follows

:

In this case

,

the filter

'

s GAIN

=

0

.

0dB

,

and being BW

=

1

.

05

,

the current filter selected is a Peaking

type

.

Now

,

rotating the PM2 encoder clockwise

,

the parameter BW will range from 0

.

05 up to 3 for

identifying a bandwidth value for a Peaking filter

.

If a Peaking filter is selected

,

then the Gain can be modified from 0

.

0dB and the BW will range

between 0

.

05 and 3

.

If the user wants to select a Shelving filter from the above setting

,

with the GAIN

=

0

.

0dB

[

if the

GAIN is not 0

.

0dB

,

it is necessary to set it at 0

.

0dB using the PM3 encoder

],

rotate the PM2

counter

-

clockwise

.

Once BW reaches the 0

.

05 value

,

at the next step of the PM2 counter

-

clockwise rotation

,

the selection of the Shelving filters will be entered
