ENGLISH
INSTALLATION GUIDELINES:
 Install the unit in a well-ventilated location where it will not be exposed to high temperatures or humidity.
 Placing and using the unit for long periods near heat-generating sources such as amplifiers, spotlights, etc.
will affect its performance and may even damage the unit.
 The unit can be mounted in 19-inch racks. Attach the unit using the 4 screw holes on the front panel. Be
sure to use screws of the appropriate size. (screws not provided) Take care to minimize shocks and
vibrations during transport.
 When installed in a booth or flight case, please make sure to have good ventilation to improve heat
evacuation of the unit.
 To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when
bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full
performance.
CLEANING THE APPLIANCE:
Clean by wiping with a polished cloth slightly dipped with water. Avoid getting water inside the unit. Do not
use volatile liquids such as benzene or thinner which will damage the unit.
CONNECTIONS
Connections can be made with balanced/unbalanced XLR-
cables. Please only use good quality balanced cables to
minimize noise and interference. There are many different
possibilities but mainly the unit will be connected between the
output of your mixer and the different amplifiers in your
installation.
IMPORTANT: always test your connections to exclude any wiring errors!
 Make sure all MUTE buttons (8) are on.
 Activate the HF-outputs first: if your cabling is wrong, high frequencies will come out of your
subwoofers (but HF-units are still alive )
FUNCTIONS (FRONT)
1. INPUT SIGNAL METER: Indicates the level of the incoming music signal.
2. OUTPUT SIGNAL METER: Indicates the level of the music signals at the different outputs.
3. MULTIFUNCTIONAL DISPLAY: Indicates the status of the several function settings.
4. PARAMETER ENCODER: endless dial with integrated push button.

Push button: used to browse the different in/outputs

Dial: used to adjust all kinds of parameters, password characters etc. (see further)
5. PREVIOUS BUTTON: used to browse submenu options in backward direction, etc.
6. NEXT BUTTON: used to browse submenu options in forward direction, etc.
7. RECALL BUTTON: used to recall stored programs and quit menus
8. OUTPUT MUTE BUTTONS: used to put the outputs in mute (red LED is lit while in mute mode)
9.  BUTTON: used to select the different parameter values in  direction.
10.  BUTTON: used to select the different parameter values in  direction.
11. SAVE/ENTER BUTTON: used to save programs and confirm options

FUNCTIONS (rear)
12. ON/OFF SWITCH: used to switch the unit on/off. Even though the unit has soft startup, we advice to
switch the processor on before the amplifiers.
13. MAINS INPUT with IEC socket and integrated fuse holder, connect the supplied mains cable here.
14. USB CONNECTOR: used to connect the processor to a PC or laptop. With the supplied software you
can set all parameters in real time with your PC. This is much more convenient than setting up
everything directly on the processor. See further for more information.
15. RS-485 IN/OUT: can be used to interconnect several DLP-6 processors in a larger installation, using
CAT-5E (Ethernet) cable. Don't for get to set the device ID's! (see chapter "how to use") You can also
use these connections to extend the PC-link to max 100m. On the PC-side you should connect the
supplied RS-485/USB converter.
16. BALANCED OUTPUTS: use balanced XLR-cables to connect the different amplifiers to the processor.
17. BALANCED INPUTS: use balanced XLR-cables to connect the processor to the output of you mixer.
SOME WORDS EXPLAINED
Maybe it's a good idea to briefly explain some terms before we explain how this unit should be used.
DELAY ON INPUT
In big venues and for outdoor applications delays can be very useful to compensate the time lag between
individual speaker stacks. For example between the speaker stack near the podium and delay towers further
in the audience. The DLP-6 can introduce input delays up to 682,52ms or 235,07m!
DELAY ON OUTPUTS
Is used to align the individual components of a speaker stack with each other. For example you can have
mid/high cabinets flown and subwoofers on the floor: in this case the DLP-6 can compensate the time
differences with a delay, up to 21,31ms or 7,3m, on each output.
PARAMETRIC EQ
A parametric equalizer is a very effective band-pass filter with adjustable gain, center frequency and
bandwidth. It's often used to correct speakers, prevent feedback, eliminate unwanted resonances, etc. In
most cases a 5band parametric EQ is more than enough to adjust the sound to perfection.
HIGH / LOW SHELF FILTERS
Shelving filters are useful to restore the overall balance of high and low frequencies.
A low-shelf filter: passes all frequencies, but boosts or cuts frequencies below the cutoff frequency by
specified amount.
Example1: if the overall bass response of a
system is weak, you can use a low-shelf filter
to increase the low frequencies.
Example2: On the drawing a low-shelf filter is
used with frequency = 200Hz and gain set to
-18dB  all frequencies below 200Hz are
reduced by -18dB.
A high-shelf filter: passes all frequencies,
but boosts or cuts frequencies above the
cutoff frequency by specified amount.
Example: If your mix sounds a little harsh, you can use a high-shelf to reduce the high frequencies without
completely eliminating some frequencies, as would happen with a normal high-cut filter.
