3 - Applications
The DFX2448 is a digital stereo effect unit with 16 different effects, e. g. Delay, Reverb,
GatedReverb, Chorus, Flanger, etc. and effect combinations. Depending on the effect, up to 25
parameters are adjustable (table on page 3). In an audio system, the effect unit is used to modify
the sound. It is inserted in the signal path, e. g. between the microphone and the amplifier or inthe
effect way of a mixer. The DFX2448 is both suited for professional applications (e. g. studio, stage,
discotheque) and private applications (e. g. home recording). The software supplied with the unit
allows convenient control of the effect unit from a PC. As an alternative, control via MIDI will also
be possible.
4 - Setting Up and Connecting the
Effect Unit
The DFX-2448 is designed for installation into a rack (482 mm/19″), but it can also be used as a
tabletop unit. For rack installation, 1 RS is required (RS = rack space = 44.45 mm).
Prior to making or changing any connections, switch off the effect unit and the units to be connected.
1) Insert the effect unit in the signal path of the audio system according to the signal source used:
– Line mono signal source (e. g. output of a musical instrument, Effect Send output of a mixer)
Connect the signal output of the unit to be connected to the XLR or 6.3 mm jack LEFT IN (21).
* Set the switch MIC LINE
(20) to the position LINE and the switch STEREO MONO (22) to the position MONO.
– Line stereo signal source
(e. g. master signal output of a mixer) Connect the signal outputs of the unit to be connected to
the XLR or 6.3 mm jacks
RIGHT IN and LEFT IN (21).* Set the switch MIC LINE (20) to the position LINE and the switch
STEREO MONO (22) to
the position STEREO.
– Microphone
Connect the microphone to the XLR or 6.3 mm jack LEFT IN (21).* Set the switch MIC LINE (20) to
the position MIC and the switch STEREO MONO (22) to the position MONO.
Connect the OUTPUTS (19) to the line inputs of the subsequent unit (e. g. amplifier). When
returning the effect signal to a mixer, connect the OUTPUTS to the return inputs or to two input
channels of the mixer.
2) To operate the functions of the buttons FX LOAD/PAR/TAP (8) and BYPASS/ENTER (10) by
remote control via two footswitches (e. g. FS-70 from “img Stage Line”), connect the footswitches
to the jacks FX LOAD/PAR/ TAP (18) and BYPASS/ENTER (17).
3) Finally connect the mains cable provided to the mains jack (12), then connect the mains plug to
a socket (230 V~/50 Hz).
5 - Operation
1) Switch on the effect unit with the POWER switch (11). The POWER LED next to the button will
light up. The settings of the last operation will be loaded while the display (6) indicates “DFX2448
Effect Processor” and the firmware version successively. When the name of the last effect used is
displayed, the unit is ready for operation.
2) To make the subsequent settings audible, set the controls INPUT LEVEL (2), DIRECT (3), EFFECT
(4) and OUTPUT LEVEL (5) to mid- position (position 5) first. Switch on the units connected to the
DFX2448 and feed a signal to the effect unit. If the LED above the button BYPASS/ENTER (10) lights
up, press this button; otherwise no effect will be audible.
Note: If the effect signal is mixed to the direct signal in the mixer, set the control DIRECT of the
DFX2448 to “0”.
3) To adjust the input level, turn up the control INPUT LEVEL to such an extent that the overload
LED CLIP (1) will shortly light up with music peaks. Then slightly turn back the control until the LED
stops lighting up. The LED CLIP will also indicate overload of the effect processor. Therefore, when
you select another effect, the LED may light up despite the same input level. In this case, also turn
back the control INPUT LEVEL accordingly.
4) Match the output level to the subsequent unit with the control OUTPUT LEVEL (5). If the desired
output level is not reached, advance the controls EFFECT (4) and DIRECT (3).
5) Select the desired effect with the knob FX SELECT (9). Activate the selected effect with the
button FX LOAD/PAR/TAP (8) so that the name of the effect stops flashing on the display. A short
description of the different effects can be found in the following chapter.
6) Adjust the effect intensity with the control EFFECT. For a very high intensity, turn back the
control DIRECT accordingly.
7) Depending on the effect selected, different effect parameters are adjustable. To select a
parameter, press the button FX LOAD/PAR/ TAP (8) repeatedly until the second line of the display
indicates the parameter to be changed. Then make the setting with the control PAR VALUE (7).
It will be possible to store various parameter settings as presets and to activate them, if required (
☞ chapter 7.1)
The second line of the display will show the number and the name of the activated preset. The
number will appear additionally behind the effect name. The factory setting is number 1 and called
“Default”.
Notes
1. An overview of the adjustable parameters can be found in the APPENDIX. The parameters are
described in chapter 7.
2. After selecting or changing a parameter, the second line of the display will indicate the name of
the preset again if the control PAR VALUE or the button FX LOAD/PAR/TAP has not been pressed for
10 seconds.
3. If the parameters of a preset have been changed, an asterisk will appear in front of the preset
number when the second line of the display shows the name of the preset again. The changes will
be stored automatically.
4. For the effect TAP DELAY, the delay time will also be defined when the button FX LOAD/PAR/TAP
is pressed in order to synchronize the echoes to the beat of the music (☞ chapter 6.3).
8) For fine adjustment of the effect, repeat steps 4, 6 and 7, if required.
9) To activate/deactivate the effect, press the button BYPASS/ENTER (10) or use a foot- switch
connected to the jack BYPASS/ ENTER (17). With the effect deactivated, the green LED above
the button BYPASS/ ENTER will light up and on the right of the dis- play, “OFF” will appear instead
of “ON”.
Note: With the control DIRECT set to “0” and the effect deactivated, no signal will be audible at
the OUTPUTS (19).
10) After operation, switch off the unit with the POWER switch.
6 - Description of
6.1
Reverb Hall, Reverb Room, Reverb
These three effects are used to create a natural reverberation.
Reverb Hall simulates the reverberation in a large hall. It is characterized by long early reflections
and a soft, long reverberation. This effect is often used for solo instruments and lead vocals.
Reverb Room simulates the reverberation in an empty room of medium size. It is characterized by
short and distinct early reflections and a short reverb decay time. This effect is ideal for per-
cussion instruments.
Reverb Plate simulates the sound of a reverb plate. For a long time, reverb plates were used in
studios to create artificial reverberation. They provide a reverberation with emphasis on the high
frequencies. There are no early reflections so that there is no clear information concerning the
size of the room and the sound of the effect is somewhat artificial. This reverberation is often
used for solo instruments and vocals.
Effects
Plate
6.2 Reverb Vocal, Gate Reverb
These reverb effects do not simulate natural acoustics; they are used to create special effects.
Reverb Vocal simulates the reverberation in a large hall, however, with the addition of small
echoes to improve the characteristics of vocals.
Gate Reverb simulates a reverberation that is cut off by a noise gate when the reverb signal falls
below an adjustable value instead of slowly decaying. This effect is ideally suited for percussion
instruments of very short sound, e.g. snare drums and kick drum.
*6.3 mm jacks and XLR jacks may be connected at the same time; however, the 6.3 mm jacks will
deactivate the corresponding XLR jacks.
6.3 Vocal Echo, Tap Delay
The DFX2448 offers two echo effects for various applications:
Vocal Echo: This echo effect is ideally suited for vocals. It creates echoes with different delay times
in the left and right stereo channels.
Tap Delay: For this classic echo effect, the delay time is defined either via the parameter 1 “Delay”
with the control PAR VALUE (7) or by pressing the button FX LOAD/PAR/TAP (8).
To define the delay time with the button FX LOAD/PAR/TAP and to synchronize the beat of the
echoes:
1) Press the button FX LOAD/PAR/TAP once. The parameter 1 “Delay” will be displayed.
2) Press the button once again within 10 seconds, keep it pressed until its LED starts flashing. In
the second line of the display, “Delay [TM]:” and the adjusted delay time in milliseconds will
appear.
3) Press the button FX LOAD/PAR/TAP to the beat of the music. The interval between the last two
actuations will define the delay time. The delay time will be shown on the display and by flashing
of the LED above the button FX LOAD/PAR/TAP. In this case, the controls PAR VALUE and FX SELECT
are without function.
4) To select other parameters or other effects, keep the button FX LOAD/PAR/TAP pressed again
until its LED stops flashing.
Note: The maximum delay time to be adjusted is 0.8 seconds for the stereo mode and 1.27
seconds for the mono mode. The operating mode is adjustable with the parameter 15 “Mode”.
6.4 Chorus, Flange, Phaser, Tremolo,
Rotary
These effects are modulation effects, i. e. the input signal is modulated (e. g. in its pitch) and
mixed to the original input signal. Depending on the type of modulation, various effects will
result.
Chorus: This effect is used to make an instrument or a voice sound “richer”. To obtain this effect, a
part of the input signal is delayed (approx. 30 ms), the pitch is slightly varied all the time (vibrato)
and mixed to a part of the original input signal.
Flange: The Flanger effect was originally created when the same piece of music was played
simultaneously on two tape decks and the output signals of the units were mixed. Since the two
units were not completely in sync due to tolerances, increasing time differences would result
between the signals. When the signals of the tapes were mixed, various frequencies sweeping
across the frequency spectrum would cancel each other due to the variations in speed. From the
acoustic point of view, you get the impression of a jet plane flying through the music. Slowing
down a tape reel (“flange”) would systematically increase the intensity of this effect.
Phaser: The distortion in sound typical of the Phaser is created when the phase of a part of the
input signal is shifted and mixed to a part of the original input signal. The effect is mainly used for
guitars, electric pianos and keyboards.
Tremolo: A tremolo is created when the volume of a signal is rapidly increased and decreased
alternately. The effect is ideally suited for guitars, bass guitars and keyboards.
Rotary: This effect simulates rotating speakers (Leslie effect). The effect became popular in the
era of the Hammond organ for which it was mainly used. Today it is also often used by guitarists.
To stop (display indication “Stop”) and restart (display indication “Go”) the simulated rotation of
the two speakers (bass speaker and horn speaker), press the button BYPASS/ ENTER (10) or
actuate the footswitch connected to the jack BYPASS/ENTER (17). With a corresponding setting (☞
chapter 7, parameter “Switch”), it will be possible to switch the rotating speed between slow and
fast with the button FX LOAD/PAR/TAP (8) or a footswitch connected to the jack FX
LOAD/PAR/TAP (18).
As a special feature, the DFX2448 allows to set the parameters for this effect separately for the
bass speaker and the horn speaker.
6.5 Effect combinations
Chr/Flg/Reverb, Delay/Reverb,
Chr/Flg/Delay
Chr/Flg/Reverb: The effects Chorus, Flange and Reverb Room are activated at the same time.
Delay/Reverb: The effects Delay and Reverb Hall are activated at the same time
Chr/Flg/Delay: The effects Chorus, Flange and Delay are activated at the same time
6.6 Pitch Shifter
The pitch of the input signal is shifted. The maximum shifting is 12 semitones (= 1 octave) and is
adjustable in steps of one third of a semitone. To hear only the signal with the pitch shifted, set
the control DIRECT (3) to “0”, e. g. to distort a voice substantially.

7.2 Resetting all parameters to the
factory settings
If the parameters have been misadjusted so that the sound is not really good any more, it will be
easy to reset the unit: The parameter memories
1 of all effects will be reset to the default values and the memories 2 – 8 with your own settings
will be deleted.
1) Switch off the DEF-220P.
2) Keep the button BYPASS/ENTER (10) pressed and switch on the unit at the same time. The
display will show:
Set factory config.?
if yes press < Tap >
3) Press the button FX LOAD/PAR/TAP (8) to confirm. The display will show:
Reset, are you sure?
if yes press < Fx/Byp >
4) To reset, press the buttons FX LOAD/PAR/ TAP and BYPASS/ENTER at the same time. Just like
after switching on, the display will indicate the unit name and the firmware version successively.
Then the DFX2448 is ready for operation again.
8 External Control Possibilities
For controlling the DFX2448, either use the soft- ware provided or a MIDI software.
8.1 Control via the software
provided
The software provided is suitable for the operating systems Windows XP, Windows Vista and
Windows 7. It allows convenient control of the DFX2448 via a PC. All parameters of an effect are
clearly shown on the user interface and are directly adjustable. They will be stored as pre- sets
both on the PC and also in the DEF-220P.
8.1.1 Preparation
1) Connect the USB port (14) via a USB cable to the USB port of the PC.
2) Adjust the DFX-2448 for control via the USB port:
a) Keep the button FX LOAD/PAR/TAP pressed for approx. 3 seconds until the first line of the
display indicates “Config Communication”.
b) If the second line indicates “Device: < USB >” the USB poer has already been selected.
In this case, exit the setting mode (☞ step d).
c) If “Device: < MIDI=Ch . . >” is indicated, turn the control PAR VALUE (7) clockwise until “Device:
< USB >” appears
d) To exit the setting mode, keep the button
FX LOAD/PAR/TAP pressed for approx.
3 seconds until the display indicates an effect name
3) Start the file “setup.exe” to install the soft- ware from the CD on the computer.
4) Click the corresponding symbol to start the control program. Loading the program may take a
while because all parameters stored in the DFX2448 will be transferred to the PC. The screen will
show the message “Dumping memory; please wait”. After loading, the user interface of the
program will appear and the display of the DFX2448 will show “System Lock PC Connection”.
Control of the effect unit will now only be possible via the PC.
If the effect unit and the PC have not been linked correctly, only operation in the “Demo Mode”
will be possible.
8.1.2 Operation
The control program is very easy to use. All parameters are adjustable via controls or selection
boxes. To activate another effect, use the box “Effect change”. Use the button “Effect” to activate
and deactivate the effect. The other but- tons have the following functions:
Exit – to exit the control program
When the display of the DFX2448 changes from the indication “System Lock PC Connection” to
the indication of an effect name, it will be possible to operate the effect unit again with its
buttons and controls.
Save Preset To PC – to store the parameter set- tings of the activated effect as a preset on the PC;
the file extension of the preset files is “fxp”
Load Preset From PC – to load a preset previously stored on the PC
The current preset name is indicated on the left at the bottom of the user interface behind
“Preset on device =”. If parameters are changed after loading a preset, an asterisk * will appear
in front of the preset number.
Save Project To PC – to store the parameters currently set for all 16 effects
It will be possible to store the parameter settings of all 16 effects on the PC as a project. Thus, different projects for various applications may be stored; they have the file extension “prj”.
Load Project From PC – to load a project stored on the PC
After loading a project, the effect REVERB HALL will always be activated.
Reload Current Effect – to reload the parameters of the current effect if the parameters have
been changed and are to be reset to the stored values
Load Preset From Device – to load a preset stored in the DFX2448
Save Current Preset to Device – to store the parameters currently set of the activated effect as a
preset in the DFX2448
ReConnect – to reconnect the effect unit and the PC by the software, e. g. in case of errors during
data transmission

1) Connect the jack MIDI INPUT (16) via a MIDI cable to the MIDI output of the PC. The jack MIDI
OUTPUT (15) allows connection of
another MIDI-controlled unit.
2) For MIDI control, set the DFX2448 to the MIDI
channel used for controlling it:
a) Keep the button FX LOAD/PAR/TAP pressed for approx. 3 seconds until the following text is
displayed:
Config Communication
Device: < USB >
If the DFX2448 has already been controlled via MIDI, the last MIDI channel adjusted will appear
behind”Device”, i.e. “Device <MIDI Ch=12>” for control via MIDI Channel 12
b) Select the MIDI channel (1 – 16) with the control PAR VALUE (7). If the display indicates
“Device: < USB >”, turn the control counter-clockwise.
c) To exit the setting mode, keep the button FX LOAD/PAR/TAP pressed again for approx. 3
seconds until the display indicates an effect name.
3) After setting the MIDI channel, the effects will be selected with a corresponding Program
Change command. Control Change commands are used to activate and deactivate the Bypass
function and to change all effect parameters. The tables below list the values required.

To change a parameter, send two Control Change, commands to the DFX-2448:
1) First select the parameter to be changed. For this purpose, set MIDI controller 17 to the value
corresponding to the parameter number minus 1.
Example: For the effect REVERB HALL, select the parameter PEQ1 Q (bandwidth of bell filter 1):
According to the table on page 3, parameter PEQ1 Q is number 9. Therefore, set MIDI controller
17 to the value 9 – 1 = 8.
2) To change the parameter, set MIDI controller 16 to a corresponding value. Tables 3-6 list the
values to be set:
1. All values for frequencies, gain or attenuation, bandwidth and semitones are listed in table 3.
Example: If the desired bandwidth of bell filter 1 (PEQ1 Q) is 1.5 octaves, set MIDI controller 16 to
the value 29.
2. Percentage values are implemented 1: 1, see table 4. Example: To set the parameter Decay to
65 %, set MIDI controller 16 to the value 65.
3. Parameters with a switching function are listed in table 5; they are changed by the value 0 or 1.
4. The values of all parameters with a time unit can be found in table 6. Please note that the step
sizes will differ according to the adjusting range.
Example: Setting the parameter Time of the effect GATE REVERB to 100 ms: The next possible
value is 94.5 ms (3 × 31.5 ms). For this purpose, set MIDI controller 16 to the value 3.
