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.
