To change the Master Fader’s attenuation range follow 
these steps:

•   Press the GLOBAL control switch until you see the M.F..

•   Use the Data Wheel to select the operating range of 

Master Fader. 

•   To keep the new changes, press the STORE button and 

you will exit the GLOBAL mode and both the STORE and 
GLOBAL LED’s will turn off.

Selecting the Operating Mode
The D2500 can be used as a stereo device with 31-bands 
of filters and the right and left side, or as a dual mono with 
31-band equalizer for each of the mono signals. 

It is also possible to change the operation of the equal-
izer from Stereo to Dual  (two times mono). To change the 
Operating Mode, follow these steps:

•    Press the GLOBAL control switch a few times until you 

see the Md.  

•  Use the Data Wheel to select Stereo or Dual 

•   To keep the new changes, press the STORE button and 

you will exit the GLOBAL mode and both the STORE and 
GLOBAL LED’s will turn off.

Selecting the Filter Bandwidth
Thanks to the powerful onboard DSP, the D2500 has the 
ability to program the equalizer filter bandwidth for either 
1/4, 1/3, 1/2 of an octave, or to AUTO, which will allow 
each of the 31 filters to be set to an individual bandwidth 
calculated by the onboard DSP. To access the Filter band-
width settings follow these steps:

•   Press the GLOBAL control switch a few times until you 

see the  F.B.W. .

•   Use the Data Wheel to select 1/2, 1/3 or 1/4 of an octave, 

or to AUTO.

•   To keep the new changes, press the STORE button and 

you will exit the GLOBAL mode and both the STORE and 
GLOBAL LED’s will turn off.

Selecting the Fader Range
It is also possible to change the fader range of the equal-
izer filters from 3dB, to 6dB or 12dB. To change the 
Frequency Range, follow these steps:

•   Press the GLOBAL control switch a few times until you 

see the F.R.  

•   Use the Data Wheel to select +/-3dB, to +/-6dB or +/-

12dB.

•   To keep the new changes, press the STORE button and 

you will exit the GLOBAL mode and both the STORE and 
GLOBAL LED’s will turn off.

Setting the Range of the Master Fader
You can set the D2500’s Master Fader can be set to operate 
in the following ranges;  +12/-12dB, or +12/-120dB.  The 
Master Fader attenuation range is always either the same 
as the filter faders, or it can be set to -120dB. The Master 
Faders boost range will always be equal to the boost range 
of the filter faders.
