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 device has to:
-be qualified
-follow the instructions of this manual
Before your 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 device.
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 device are not subject to
warranty.
This device 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 device.
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 open the device and do not modify the device.
Do not insert objects into air vents.
Do not connect this device to a dimmerpack.
Do not switch the system on and off in short intervals, as this would reduce the system’s life.
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 device 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 device is not used or before cleaning! 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 device 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!

3
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.
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.
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”)
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
This device is not designed for permanent operation. Consistent operation breaks will ensure that the
device will serve you for a long time without defects.
If this device 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, lamp explosion, crash
etc.
You endanger your own safety and the safety of others!
Improper installation can cause serious damage to people and property !

Receiver Functions
1. Limiter function;
If the limiter is switched on, the volume will corrected automatically if the value rises above the set
threshold. This in order to avoid distortion and protect your ears.
2. Equalizer setting:
Treble boost 6dB
Bass boost 6dB
Bass + treble boost 6dB
flat
3. Squelch setting:
If the RF signal is less then the squelch setting. The signal indicator will dim and the audio output
will be muted.
Mix Mode/ Stereo Control
The receiver receives two signals (1/L and 2/R) from the transmitter and then processes these signals in
either mix or stero mode.
Stereo Mode
In stereo mode the signals remain separate so that 1/L is heard through the left headphone and 2/R is
heard through the right headphone. The balance knob on the receiver can be used to adjust the
balance between the left and right headphones. See Figure 14.
Fig. 14
Mix Mode
In Mix mode the 1/L and 2/R signals are mixed into a mono signal using the balance knob. The mono
signal is sent to headphone L and headphone R. See Figure 15.
Fig. 15
Mono Mode
Used when only one (mono) monitor mix is available.

11
Adjusting the squelch threshold.
Interference due to other transmission links can be eliminated as follows:
Switch off the transmitter. The receiver should no longer receive a signal.
If the receiver still receives a signal, increase the squelch threshold so that the signal will no longer
be received. If the signal cannot be eliminated in this way, set the transmitter and the receiver to
a different channel.
Switch on the transmitter again and check if the receiver receives the transmitter signal.
Note:
If the squelch threshold is adjusted to high, the transmission range will be reduced. Therefore
always adjust the squelch control to the lowest possible setting.
Tips for achieving maximum performance.
Make sure you can always see a receiver antenna from the transmitter position.
Keep the distance from transmitter to receiver antenna as short as possible.
Point the receiver antennas away from each other at 45 degrees angle from vertical position.
Avoid placing the receiver antennas near metal surfaces and obstructions.
Replace battery as soon as low battery LED lights.
If stacking or rack mounting receivers in a multiple system setup. Do not allow antennas to cross.
Perform a walk-through before performance or presentation. If dead spots are found, adjust the
location of the receiver. If dead spots remain, mark the dead spots and avoid them.

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.
