• Press the FBM switch and use the Data Wheel to and

select FBM: ON.

• Now, engage the effect by pressing the IN / OUT switch

until the yellow LED lights.

• To access the Feedback Sensitivity parameter, press the

FBM switch until you see the menu, Sensitivity. The

Feedback Sensitivity is used to set the threshold that the

D2500 uses to recognize feedback. Now you can select a

Sensitivity of 0 – 10.

• To access the Feedback Hold Time parameter, press the

FEEDBACK switch until you see the menu, FB Hold. The

D2500’s Feedback management system uses HOLD time

to keep a filter cut after the system identifies feedback.

Now you can select a Hold time of 5– 300 seconds.

• To access the Feedback Release Time parameter, press

the FEEDBACK switch until you see the menu, FB Rel..

Now you can select a Release time of 20 – 300 seconds.

If the feedback is temporary, the D2500 will attempt

to restore the fader back to the original position. The

Release time, is the time the D2500 takes to return the

fader back to the original level.

Using the Internal Noise GATE

The D2500 digital effect section includes a digital noise

gate that can be very useful in eliminating the system

hums and buzzes that may occur, especially when you

moveyour system from venue to venue. A noise gate is a

powerful dynamics processor that works like an automatic

mute. Simply put, when the desired signal is present, the

gate is open and the sound can be heard. When the signal

is soft, like when the music stops, and all you hear are the

hums, buzzes and system noise floor, the gate is closed.

The

D2500 GATE has variable control over Threshold and

Release time. Threshold is the level you set at which the

noise gate will close (mute the sound). You want to set a

level in between the noise floor and the normal operating

level of your program. Release Time is the amount of time

the D2500’s Gate takes to return the signal to the original

level after the signal rises above the Threshold level.

The Noise Gate Switch Has Two Clicks!

Click Menu Function Value

1 Gate Rel. Release Time 50 - 100 %

2 Gate Th. Threshold Level

0 - -100 dB

To operate the D2500 digital noise GATE, follow these

simple steps:

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

• Now, engage the effect by pressing the IN / OUT

switch until the yellow LED lights.

• To access the Threshold parameter, press the GATE

switch once or twice until you see the menu, Gate Th.

The Gate Threshold can be set from –100 dB to 0 dB.

• To access the Release parameter, press the GATE

switch until you see the menu, Gate Rel. The Gate

Release time can be set from 50 to 100 %, which is the

equivalent to 2 to 15 seconds.

Using the

Internal

DELAY

The D2500 offers an on board Digital Delay to time align

speakers for phase correction and for setting up delay

clusters in large venue sound systems. The Delay can

be set from 0 to 85 milliseconds. (Optional memory can

be added for longer delay times.) Setting the delay is a

simple procedure which can be accomplished by follow-

ing the next few steps:

• Press the DELAY 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 delay

time for your application.

Using the

Internal

ENHANCER

The D2500 has unique digital Enhancer, which can help

sweeten a sound system, and at the same time, reduce

unwanted noise. The D2500’s Enhancer uses several

powerful algorithms to analyze the signal content and

then decide how to enhance the signal; based on that

content. If the D2500 Enhancer senses that there is

music playing with good high frequency content, it will

slightly boost these frequencies creating sweet and

airy top-end response. When the D2500 Enhancer sees

that there is little or no high-frequency content, it will

slightly reduce the high-frequency response of the sys-

tem. This can be especially useful since often when the

high-frequency content is very low, or off, the only thing

you hear is system hiss. The Enhancer will recognize the

noise and reduce it by cutting the associated EQ filters

automatically.
