Operating the D2500
Using the Internal LIMITER for Basic Speaker
Protection
In order to help you protect your speaker system, the
D2500 employs a digital Limiter. The D2500's Limiter is a
brick wall type with a very fast attack time and a very slow
release time. When engaged, the digital Limiter will pre-
vent signals from reaching outputs levels over a desired
point. The D2500’s Limiter has a variable Threshold level,
which is the point the limiter circuit begins to attenuate
the system. The Limiter also has a variable Release time,
which is the time the limiter circuit takes to return the sig-
nal to the original level.
The LIMITER Switch Has Two Clicks!

Using the A/B Feature
The A/B switch lets you compare the actual, modified
program to the last program recalled or stored in memory.
After you load a preset you may want to make some
changes to the equalization curve or perhaps to one or
more of the digital effects. Once you make some changes
you may want to compare the edit with the original pre-
set saved in memory. You can compare the current set
with the preset that is stored in memory by using the A/B
switch. Try the A/B function to compare and preset to an
edit by following these steps:
• Press the LOAD switch and select any preset, then press
LOAD again to recall the preset into memory.
• Play some music through the D2500.
• Now change the position of the faders so you can hear
the equalization curve change.
• At this point you will notice that the green LED on the
A/B switch is lit, indicating that there has been a change
to the original preset.
• Now, press the A/B switch again and the green LED will
flash indicating that the D2500 has now returned all the
EQ faders and effects parameters back to the positions
that were saved in the presets. You can continue to press
the A/B switch to toggle back and forth between the
saved preset and the new sound.
If you like the new edited preset you can use the STORE
function to save the new preset either under the current
memory location or a new one.
