FOR YOUR OWN SAFETY, PLEASE READ THIS USER MANUAL CAREFULLY

BEFORE YOUR INITIAL START-UP!

WARNING

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.

Never leave any cables lying around.

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 the device and do not modify the device.

Do not drive the inputs with a signal level bigger, than required to drive the equipment to full

output.

Do not plug Mics into the console (or stagebox) while Phantom Power is on. Also mute the monitor

/ Pa system when turning Phantom Power on or off. Allow the system to adjust for a couple of

seconds, before setting the input gains.

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.

Always operate the unit with the AC ground wire connected to the electrical system ground.

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.

CAUTION!

Keep this system away from rain and moisture!

CAUTION! Be careful with your operations.

With a dangerous voltage you can suffer

a dangerous electric shock when touching the wires!

Make sure that the available voltage is not higher than stated on the rear panel.

Make sure that the power-cord is never crimped or damaged. Check the system and the power-

cord from time to time.

Please turn off the power switch, when changing the power cord or signal cable, or select the

input mode switch.

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 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”)

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.

If your Dap Audio device fails to work properly, discontinue use immediately. Pack the unit

securely (preferably in the original packing material), and return it to your Dap Audio dealer for

service.

Repairs, servicing and electric connection must be carried out by a qualified technician.

For replacement use fuses of same type and rating only.

WARRANTY: Till one year after date of purchase.

OPERATING DETERMINATIONS
