PRODUCT SAFETY
This product is manufactured with the highest standards and is double-checked in our quality control
department for reliability in the "HIGH VOLTAGE" section.
CAUTION
Never remove any panels, or open this equipment. No user service-able parts inside.
Equipment power supply must be grounded at all times.
Only use this product as described, in user manual or brochure.
Do not operate this equipment in high humidity or expose it to water or other liquids.
Check the AC power supply cable to assure secure contact.
Have your equipment checked yearly by a qualified dealer service center.
Hazardous electrical shock can be avoided by carefully following the above rules.
EXTRA CAUTION FOR LIVE MIC RECORDING
Ground all equipment using the ground pin in the AC power supply cable. Never remove this pin.
Ground loops should be eliminated only by use of isolation transformers for all inputs and outputs
(optional).
Replace any blown fuse with the same type and rating only after equipment has been disconnected
from AC power. If problem persists, return equipment to a qualified service technician.
PLEASE READ THE FOLLOWING INFORMATION
Especially in sound equipment the following information is essential to know.
An electrical shock is caused by voltage and current, actually it is the current that causes the shock.
In practice the higher the voltage the higher the current will be and the higher the shock.
But there is another thing to consider and it is resistance. When the resistance in Ohms is high
between two poles, the current will be low and vice versa.
All three of these; voltage, current and resistance are important in determining the effect of an
electrical shock.
However, the severity of a shock is primarily determined by the amount of current flowing through a
person.
A person can feel a shock because the muscles in a body respond to electrical current and because
the heart is also a muscle it can be affected when the current is high enough. Current can also cause
the chest muscles to contract, which affects your breathing.
At what level is current dangerous?
Well the first feeling of current is a tingle at 0.001 Amp of current. The current between 0.1 Amp
and 0.2 Amp is fatal.
Imagine that your home fuses of 20 Amp can handle 200 times more current than is necessary to kill.
How does resistance affect the shock a person feels. A typical resistance between one hand to the
other in "dry" condition could well over 100,000 Ohm.
Always earth all your equipment by the grounding pin in your main plug.
Proper wiring and isolation input/output transformers (optional) should only cure Hum loops.

PRODUCT SAFETY
Replace fuses always with the same type and rating after the equipment has been turned off and
unplugged.
If the fuse blows again you have an equipment failure, do not use it again and return it to your dealer
for repair.
And last but not least be careful not to touch a person being shocked as you, yourself could also be
shocked. Once removed from the shock, have someone send for medical help immediately
Always keep the above-mentioned information
in mind when using electrically powered
equipment.

Introduction
1 Introduction
This manual will give you a detailed explanation of the functionality of the Oxygen 4 Digital and all its
features.
It is advised to read this manual once before touching any control, or even thinking about hooking up
the system.
We know that that is actually the firsts thing you want to do but please do NOT and discipline yourself
to read the manual first.
The manual gives all sorts of valuable information before getting started and it saves you from getting
in touch with us for all sorts of questions. You can use this manual later on as a reference.
In the first chapters we shall give you an overview of the Oxygen 4 Digital and its features. In this way
you can have an impression of how to implement the system in your application.
The next chapters will deal with interconnecting the various parts of the system and its external
interfacing with your equipment
When the Oxygen 4 Digital is installed and wired, you can finalize its interfacing with the instruction in
the following chapters.
After having installed the Oxygen 4 Digital you will have a very complete mixer with a human interface
that is very logical and understandable by intuition.

Unpacking
2 Contents of the package
The following parts should be inside the package.
•1x 19” Racks depending on the ordered configuration
•One or two 4-fader Control Surfaces or one 8-fader Control Surface depending on the ordered
configuration
•1 or 2 15Pins cable depending on the ordered configuration
•1x Power cable
•1x Crosslink network cable
•1x CD-rom
•This manual
3 Start working with the Oxygen 4 Digital
The internal power-supply is auto-sensing for the range of [85-264V/47-63Hz]. If the power coming
from your wall-outlet is not according these specs, do NOT connect the Oxygen 4 Digital.
Take the fader module and the 19”Rack unit out of the box.
Hook up the 15p sub-D cable between the fader module to the 19” rack unit (“TO CNTRL UNIT 1”)
You can now also hook up the UTP cable to your ETHERNET 802.3 network if you would like to make
settings. In chapter 10.5 you can find how to setup the Oxygen 4 Digital for networking.
Connect the power supply cable to the 19" rack and to the wall outlet.
Turn on the power.
After 3 seconds you must have control over the DSP engine. You can hit ON/CUE buttons to check
functionality. Further there are enhanced functions in the Master Section, one example:
Hit the button SRC (Source selection for this module). You can turn the encoder at the channel to
make your selection. Pushing the encoder means the default setting. The functions Prog and Sub
don’t have a rotating function… they only respond to the pushdown action!

System structure
4 System structure
The Oxygen 4 Digital system is a high-tech digital system, which is based on a 19” 2HE rack. In
combination with the control surface(s) you will get a very easy to use console with many features that
can work as a standalone unit and has a boot time of a couple of seconds (if network is disabled).
The control surface(s) give you direct access to all the parameters you need to control in real time.
Like the Fader level, routing and EQ/Dynamics. All other advanced settings can be done by using the
web server or remote software (ActiveX) by Ethernet.
4.1 19” Rack
The 19” rack is the engine of the Oxygen 4 Digital. All audio processing and routing takes place in this
unit.
This rack can work without Control Surface or Remote Software. On this 19” rack you can find 4
MIC's, 2 Mono analog and 5 Stereo analog Inputs, 7 Stereo Digital Inputs and Outputs all with sample
rate
converters. You have dedicated analog outputs for PROG, SUB, AUX, CRM and PHONES. All
interfacing and connectors are explained in the section Hardware.
4.2 Control Surface
A separate unit with knobs and faders is used to control the Oxygen 4 Digital. There are two
connections at the 19” rack to make it possible to have at maximum 8 (stereo) faders. Further this
control surface holds a phones jack which gives the CRM signal!
The Control Surface is a very simple and easy to understand interface to the Oxygen 4 Digital engine.
You can use the surface for all basic functionalities such as; Source select, EQ settings, Dynamics
Settings, Routing etc.
A separate master section gives the possibility to determine the function of the module encoders and
the CRM source. Of course you can adjust the CRM level and the DIM and Talkback.
4.3 Software (external)
By using the Ethernet connection you have the possibility to control the Oxygen 4 Digital from every
workplace in your network. By using a crosslink cable you also can use the Oxygen 4 Digital on a
stand-alone PC.
The Oxygen 4 Digital can receive an IP address via a DHCP server, or you can give a Fixed IP ! When
this IP is known, you are able to connect to the Oxygen 4 Digital by software (HTTP web server or
ActiveX object). Later we will give an overview on the options you have with the remote software/web
server.

5.1 Input matrix
To give you the flexibility you need in your applications the Oxygen 4 Digital has a full matrix before
processing takes place. You can assign one of your inputs to the eight modules in any way you want.
Furthermore you can bring one of the inputs to the external inputs to make them available at the CRM
buss.
5.2 Buss structure
As mentioned before, every module features EQ- and dynamic processing. This is why these channels
are often referred to as ‘processing’ channels.
The output of the 8 stereo audio processing channels can be routed to different busses.
Busses that are available are:
•Stereo program buss.
•Stereo sub buss.
•Stereo aux. buss.
•Stereo CUE buss.
•Automatic Mono Cleanfeed 1
•Automatic Mono Cleanfeed 2
The 6 CRM sources (Prog, Sub, Aux, CUE, Extern 1, Extern 2) may be summed into the CRM buss.
