WARNING
FOR YOUR OWN SAFETY, PLEASE READ THIS USER MANUAL CAREFULLY
BEFORE YOUR INITIAL START-UP!
SAFETY INSTRUCTIONS
Every person involved with the installation, operation and maintenance of this system has to:
-be qualified
-follow the instructions of this manual
Before you initial start-up, please make sure that there is no damage caused by transportation. Should there
be any, consult your dealer and do not use the system.
To maintain perfect condition and to ensure a safe operation, it is absolutely necessary for the user to follow
the safety instructions and warning notes written in this manual.
Please consider that damages caused by manual modifications to the system are not subject to warranty.
This system contains no user-serviceable parts. Refer servicing to qualified technicians only.
IMPORTANT:
The manufacturer will not accept liability for any resulting damages caused by the non-observance of
this manual or any unauthorized modification to the system.
•Never let the power-cord come into contact with other cables! Handle the power-cord and all
connections with the mains with particular caution!
•Never remove warning or informative labels from the unit.
•Never use anything to cover the ground contact.
•Do not insert objects into air vents.
•Do not connect this system to a dimmerpack.
•Do not switch the system on and off in short intervals, as this would reduce the system’s life.
•Do not open this device. Risk: hazardous radiation exposure.
•Do not run the output of any amplifier channel, back into another channel’s input.
•Do not connect (parallel or series) an amplifier output with any other amplifier output.
•Only use system indoor, avoid contact with water or other liquids.
•Avoid flames and do not put close to flammable liquids or gases.
•Always disconnect power from the mains, when system is not used. Only handle the power-cord by
the plug. Never pull out the plug by tugging the power-cord.
•Make sure you don’t use the wrong kind of cables or defective cables.
•Make sure that the signals into the mixer are balanced, otherwise hum could be created.
•Make sure you use DI boxes to balance unbalanced signals; All incoming signals should be clear.
•Make sure that the available voltage is not higher than stated on the rear panel.
CAUTION!
Keep this system away from rain and moisture!
CAUTION! Be careful with your operations.
With a dangerous voltage you can suffer
a dan
g
erous electric shock when touchin
g
the wires!

•Make sure that the power-cord is never crimped or damaged. Check the system and the power-cord
from time to time.
•Always operate the unit with the AC ground wire connected to the electrical system ground.
•Connecting amplifier outputs to oscilloscopes or other test equipment, while the amplifier is in
bridged mode, may damage both the amplifier and test equipment.
•Do not drive the inputs with a signal level bigger, than required to drive the equipment to full output.
•In system setup, the amplifier's output power must be 50%-100% more than the loaded
loudspeakers rated power.
•Please turn off the power switch, when changing the power cord or signal cable, or select the input
mode switch.
•In typical use, Please set the volume to 0dB position.
•Sometimes, when you want to send one signal to more than one amplifier, you should use a signal
distributor.
•Extreme frequency boosts in connection with a high input signal level may lead to overdriving your
equipment. Should this occur, it is necessary to reduce the input signal level by using the INPUT
control.
•To emphasize a frequency range, you don’t necessarily have to move its respective sliding control
upward; try lowering surrounding frequency ranges instead. This way, you avoid causing the next
piece of equipment in your sound path to overdrive. You also preserve valuable dynamic reserve
(“headroom”)
•For replacement use fuses of same type and rating only.
•Prevent distortion! Make sure that all components connected to the DCL-2 have sufficient power
ratings. Otherwise distortion will be generated because the components are operated at their limits.
•Avoid ground loops! Always be sure to connect the power amps and the mixing console to the same
electrical circuit to ensure the same phase!
•If system is dropped or struck, disconnect mains power supply immediately. Have a qualified
engineer inspect for safety before operating.
•If the system has been exposed to drastic temperature fluctuation (e.g. after transportation), do not
switch it on immediately. The arising condensation water might damage your system. Leave the
system switched off until it has reached room temperature.
•Repairs, servicing and electric connection must be carried out by a qualified technician.
•WARRANTY: Till one year after date of purchase.
OPERATING DETERMINATIONS
If this system is operated in any other way, than the one described in this manual, the product may suffer
damages and the warranty becomes void.
Any other operation may lead to dangers like short-circuit, burns, electric shock, etc.
You endanger your own safety and the safety of others!
Improper installation can cause serious damage to people and property !

be edited again, the editable programs for the user can only start from no. 04. The maximum sequence
number; 20
Press the or - button to move the cursor to the correct position and then turn the encoder 4 to select
the correct editable symbol. Press it again and the information SAVE NOW disappears after 3 seconds,
which indicates that the function is finished.
MIDI
Able to receive REAL TIME transmission data through MIDI connection.
MIDI IN
Any MIDI data sent to the DCL-2 (sequencer, MIDI footswitch, etc.) is received via the MIDI IN jack. For
example, if you wish to use the DCL-2 as an effect device for a guitar rack, you can connect the MIDI In jack
to a MIDI footswitch, which allows for selecting program presets. Another possibility, if your footswitch
allows it, is to control a parameter eg. Volume L. with an expression pedal. Per expression pedal you can
only control 1 parameter.

Connection Cables
Take care of the connector cables, always holding them by the connectors and avoiding knots and twists
when coiling them: This gives the advantage of increasing their life and reliability, which is always to your
advantage.
Periodically check that your cables are in good condition, that they are correctly wired and that all their
contacts are perfectly efficient: a great number of problems (faulty contacts, ground hum, discharges, etc.)
are caused entirely by using unsuitable or faulty cables.

Maintenance
The DCL-2 equalizer requires almost no maintenance. However, you should keep the unit clean. Disconnect
the mains power supply, and then wipe the cover with a damp cloth. Do not immerse in liquid.
Keep connections clean. Disconnect electric power, and then wipe the audio connections with a damp cloth.
Make sure connections are thoroughly dry before linking equipment or supplying electric power.
Replacing a Fuse
Power surges, short-circuit or inappropriate electrical power supply may cause a fuse to burn out. If the fuse
burns out, the product will not function whatsoever. If this happens, follow the directions below to do so.
1. Unplug the unit from electric power source.
2. Insert a flat-head screwdriver into a slot in the fuse cover. Gently pry up the fuse cover.
3. Remove the used fuse. If brown or unclear, it is burned out.
4. Insert the replacement fuse into the holder where the old fuse was. Reinsert the fuse cover. Be sure to
use a fuse of the same type and specification. See the product specification label for details.
Troubleshooting
Dap Audio DCL-2
This troubleshooting guide is meant to help solve simple problems.
If a problem occurs, carry out the steps below in sequence until a solution is found. Once the unit operates
properly, do not carry out following steps.
1. If the device does not operate properly, unplug the device.
2. Check the power from the wall, all cables etc.
3. If all of the above appears to be O.K., plug the unit in again.
4. If you are unable to determine the cause of the problem, do not open the equalizer, as this may damage
the unit and the warranty will become void.
5. Return the equalizer to your Dap Audio dealer.
