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.
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.

Installation
Remove all packing materials from the Oxygen. Check that all foam and plastic padding is removed.
Connect all cables.
Always disconnect from electric mains power supply before cleaning or servicing.
Damages caused by non-observance are not subject to warranty.
1. Line 1 /Line 2 + Peak LED
You can switch between Line 1 or Line 2
2. Mic 1
3. GAIN
Mic Channel input level is determined by the Gain control.
With the Gain control you can adjust the MIC or LINE input-sensitivity, while optimally
matching the incoming signals to the mixer’s internal operation level. When dealing
with very low input levels (example vocal recordings or distant sound sources) the
high gain is extremely profitable.
How to set the Input level:
1) Set the gain control and the corresponding channel fader to their minimum setting.
2) Connect the desired sound source (CD player, microphone, ect) to the
corresponding MIC or LINE input.
3) Play the sound source at its highest volume setting; respectively, sing or speak as
loud as possible directly into the microphone.
4) While doing so, adjust the input level using the gain control, so that during the
loudest passages the PEAK LED is just not lit, but the SIGNAL-LED lights
constantly.
This basic channel setting leaves you at least 8dB headroom. This means, you have
at least 8dB before signal clipping. If you want to make further adjustments to the
channel’s EQ setting, you should repeat step 3 and 4 again.
4 / 5 / 6. Equalizer SECTION (HI / MID / LOW)
The mixer’s Equalizer section allows shaping of the incoming audio signal. All mono
input channels are fitted with 3-band EQ. The upper (6) and lower (9) shelving
controls have their frequencies fixed at 12 Khz and 80 Hz respectively. The Mid range
control (8) has a peaking response frequency at 1.2 Khz. 2 bands have up to 15, and
Low has up to 18 dB cut and boost, with a centre detent for “OFF”. Turning the
Equalizer level control to the right amplifies the frequency range, turning to the left
attenuates the signal. Minor changes to the Equalizer control usually produce the best
results. Try to avoid excessive enhancement of the MID band.
7. Balance
Change the balance from Left to Right.
Note: The Balance does not function when you are in Mono Mode
8. PFL
The PFL button (pre fade listening) is designed to override the main signal, so
although an individual channel is heard, it is not in complete isolation. If you push the
PFL button, regardless of the Aux rotary control, you will get the complete signal in
your headphone/monitors. This is useful, because the recording engineer hears some
of the main signal. So the channel is not only heard, but also in context. Pressing this
button assigns a channel’s audio signal to the PFL bus. Simultaneously assigning
more than one channel to the PFL bus is possible, while the individual channel’s
7
volume fader setting is not recognized (PRE FADER LISTEN). Once a PFL button is
pressed, the master display automatically enters PFL/PGM mode. This allows you
setting a signal’s correct level or making special EQ-adjustments without the need of
including it in the main mix.
9. Channel Fader
A high-quality true logarithmic 100mm fader, which controls the volume of a single
channel and to establish an accurately proportioned mix of all input signals. The
channel faders should be positioned within the range of -6dB to 0dB, leaving you with
sufficient room to allow precise matching of differences in the channel’s level settings.
The overall volume is set with the master fader. Even though the channel faders offer
an additional gain of +6dB.
10 LED VU Meter
11. MASTER 1 Fader
A high-quality true logarithmic 100mm fader, which controls the Balanced
Master 1 output level (23).
12. MASTER 2 Fader
A high-quality true logarithmic 100mm fader, which controls the Master 2
output level (27).
Please, make sure to close the fader of the corresponding input channel
or at least the MASTER controls before connecting any audio signal
sources. This will save yourself, your audience, and your equipment
from unnecessary stress resulting from plug-in noise.

13. ON / OFF
14. Master 1 Stereo / Mono
You can switch between Master 1 Stereo or Master 1 Mono.
15. Master 2 Stereo / Mono
You can switch between Master 2 Stereo or Master 2 Mono.
16. VU Meter Master 1/Master 2/ PFL
You can switch between Master 1, Master 2 or PFL
17. Effect-PFL ON/OFF
18. Effect-PFL
You can change the Effect level.
19. Booth
You can change the volume of the DJ Booth with this knob.
20. PFL / Master + PFL
21. Phones
This control allows you to adjust the headphones’ volume. Phones controls 22, range
0-10
Caution: Depending on the type of headphones connected to the phones jack, the
Oxygen is capable of producing very high output levels via the phones output.
Therefore, make sure to turn the control all the way to the left (minimum setting)
before connecting the headphones.
Be aware of the fact that listening to loud sound pressure levels over a longer period
of time leads to hearing-damage!
22. Phones
You can connect a pair of headphones with an impedance of 32 - 600 Ohm to this Stereo Phones jack.
Balanced 1/4” TRS socket, wired as Tip=left, Ring=right and sleeve = ground.

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.
