Once the highs return, the Enhance releases automatically.  
Of course the D2500 let’s you dial up just the right amount 
of Enhancer for your project, so follow the steps below to 
activate the Enhancer.

•  Press the ENHANCER switch so that the yellow LED is lit.

•  Engage the effect by pressing the IN / OUT switch until 
the yellow LED lights.

•  Now,  use the Data Wheel to select the correct Enhancer 
setting , from 0 to 100%, that’s right for your application.

Setting up and Using the High Pass and Low Pass Filters

The D2500 includes digital High-pass and Low-pass fil-
ters for creating quick equalization curve contours.  A 
Hi-pass filter, (sometimes called a low-cut filter), is used 
to attenuate the frequencies below a certain point. The 
HP filter passes the highs, but cuts the lows.  A Low-pass 
filter, (sometimes referred to as a high-cut filter), is used 
to attenuate the frequencies above a certain frequency 
point. The LP filter passes the lows, but cuts the highs.  

You can use the High and Low pass filters for a variety of 
applications.  Using the High-pass filter can be especially 
useful in removing the low frequencies that can some- 
times cause stage rumble. If you have a lot of high fre-
quency system noise and hiss, you can use the Low-pass 
filter to roll-off the high-end of your system.  When equal-
izing a monitor system, you may use both the HP and LP 
filters to roll-off the high and lows for a vocal eq contour.

Any good high and low-pass filter will allow you to choose 
the cut-off frequency, and also, the order, or slope, at 
which the filter will attenuate. The D2500 lets you set the 
frequency at which the HP or LP filters cut from, as well as, 
a slope of either 6,  12 or 18 db per octave.

The HP / LP Switch Has Four Clicks!

Click  Menu 

Function 

Value

Highpass  low Cut Filter 

20 Hz - 200 Hz

HP-Order  Filter Slope 

0, 6, 12, 18 per Octave

Lowpass  low Cut Filter 

2 kHz - 20 kHz

Lp-Order  Filter Slope 

0, 6, 12, 18 per Octave

•  Press the HP / LP switch so that the yellow LED is lit.

•   Engage the effect by pressing the IN / OUT switch until 

the yellow LED lights.

•   To set the High-pass filter press the HP / LP switch until 

the LCD display reads; High-pass.

•   Now, use the Data Wheel to set the frequency from 20 

Hz to 200 Hz.

•   Press the HP / LP switch again and you will see the menu 

to set filter Order, or slope.   The menu will read HP-
Order.

•   Use the Data Wheel to choose a slope of either 6dB, 

12dB, or 18 dB.

•   To set the Low-pass filter, press the HP / LP switch until 

the LCD display reads; Low-pass.

•   Now, use the Data Wheel to set the frequency from 20 

kHz to 2 kHz.

•   Press the HP / LP switch again and you will see the menu 

to set filter Order, or slope. The menu will read LP-Order.

•   Use the Data Wheel to choose a slope of either 6dB, 

12dB, or 18 dB.
