1 OXYGEN 4 SERIES - INTRODUCTION
The Oxygen 4 is a specially designed On-Air broadcast console. The console is fully modular, which means
flexibility in the configuration. The Mono, Stereo, Telco and Telephone input modules can be placed anywhere in
the chassis. A partially loaded Oxygen 4 can be completed using low cost 'blind’ (cover) modules. The modular
approach to the design means that module replacement, or expansion of the system can be carried out quickly
and efficiently.
Telephone modules feature a built-in, high quality telephone hybrid and Telco modules can be interfaced to every
external hybrid.
Oxygen 4’s wide range of functions provides the most immediate and complete control over your radio
broadcasting. For instance, it provides: Start/Stop commands, Studio - Control Room speakers cut-off, phantom
microphone powering. All input/output connections are balanced on 1/4” jacks for Line signals and on regular XLR
connectors for mics. The Oxygen 4 has also extensive possibilities for signaling and communications. Mono
modules allow to activate ON-AIR lamps, a TalkBack circuitry permits the easiest communication between Control
Room and Speaker booth.
Oxygen 4 console is available in four frame sizes: the Frame 10, which can contain 10 overall modules, the Frame
20 and the Frame 30. A MeterHood frame version (named VMH) is also available, which presents four traditional,
needle backlit Vu Meters housed in an elegant meterbridge. A practical script tray may be fitted on both Frame 30
and VMH models.
1.1
OXYGEN 4 – AVAILABLE FRAME SIZE
The frames are inox steel + aluminium made, with wood finishing touch. Each console has always two output
modules (Master/Sub and Monitor) to the far right which controls the Studio/Control Room monitoring, pre-fade listen and
talkback functions together with the output selection (Stereo / Mono) of the Master and Sub signals. The meter bridge
contains four VU / PPM meters with user control over the source (Tuner, Master, Sub, PFL) to be displayed on the
meters.

9 FIRST INSTALLATION RECOMMENDATIONS
9.1
POWER SUPPLY CABLE
A power supply cable of approx. 2 mt length is supplied with the device, which has a moulded IEC plug attached – this is
a legal requirement.
The type of plug for the power supply depends on the country in which it is delivered.
If for any reason, you need to use this appliance with a different plug, you should use the following wiring guidelines in
replacing the exsisting plug with the new one:
Earth
Neutral (N)
Live (L)
Green, or green and yellow
Blue
Brown
Supply cables should be laid in such a manner that one does not step or walk on them. They should not be squashed by
any objects.
THIS EQUIPMENT MUST BE EARTHED.
The chassis is always connected to mains earth to ensure your safety: check your mains wiring and earthing before
switching on.
9.2
AC MAINS VOLTAGE SETTING (230 V / 115 V)
BE SURE THAT THE UNIT IS SET TO THE CORRECT MAINS/LINE VOLTAGE FOR YOUR
COUNTRY BEFORE PLUGGING IT INTO THE WALL OUTLET !
The actual Mains voltage is indicated on the label stuck on the equipment closure. Should the type of power at the
operation location not be known, please contact your dealer or electricity company.
If, for some reason, the unit is to be operated at a mains input voltage which is different to that as supplied, you need to
switch the voltage selector on the right side of the unit. You also need to replace the AC main fuse, according to
information provided on the external label or on the Technical Specifications table at the end of this user manual.
CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK, ALWAYS DISCONNECT THE AC
MAINS CABLE BEFORE ALTERING THE CHANGE-OVER SWITCH. NO USER SERVICEABLE

FUSE REPLACEMENT
The power supply socket has an integral fuse drawer containing the AC power fuse and a spare, both of the same value.

BEFORE REPLACING THE POWER FUSE, MAKE SURE YOU HAVE THE RIGHT TYPE OF FUSE FOR
THE VOLTAGE TO BE PROTECTED.
USING WRONG FUSE TYPE WILL RESULT IN INSUFFICIENT PROTECTION.
Make sure that the power is switched off and the power cable is disconnected from the equipment.
a.
Open the fuse drawer using a small blade screwdriver.
b. Replace the fuse located at the internal position
c.
Push the fuse socket back into the original position (a.)
Perform the set-up under static control conditions. Static charges are likely to completely destroy one or
more of the CMOS semiconductors employed in the unit. Static damage will not be covered under
warranty.
Basic damage prevention consists of minimizing generation, discharging any accumulated static charge
on your body and preventing that discharge from being sent to or through any electronic component.
Uninsulated dangerous voltage are inside the enclosure, voltage that may be sufficient to constitute a
risk of shock.
Always disconnect to AC Mains before removing the top cover

PROTECTION AGAINST LIGHTNING
Should the device be put out of action due to being struck by lightning or excess voltage, disconnect it
from the power supply without delay. Do not reconnect until the device has been checked. If in doubt
contact the technical support service.
Make sure there is suitable lightning protection to protect the device.
Alternatively you should disconnect all connectors from the device during a storm or when the device
is going to be unsupervised or not used for a longer period of time.
These measures will protect against damage by lightning or excess voltage.
9.5
VENTILATION
The equipment will operate as a free-standing unit without requiring any special cooling arrangement.
However, slots and openings in the product are provided for ventilation. They ensure reliable operation of the product,
keeping it from overheating. These openings must not be blocked nor covered during operation.
YOU MUST LEAVE AT A MINIMUM ONE RACK UNIT OF EMPTY SPACE ABOVE THE EQUIPMENT TO ENHANCE
VENTILATION AND TO GET A LONGER EQUIPMENT LIFE.
9.6
EARTHING
The connection to earth (ground) in an audio system is crucial for two reasons:
1. SAFETY
2. AUDIO PERFORMANCE
For safety it is important that all equipment earths are connected to mains earth so that exposed metal parts are
prevented from carrying high voltage which can injure the operator.
The same earth is also used to shield audio cables from external interference such as the hum fields associated with
power transformers, lighting dimmer buzz, and computer radiation. Problems arise when the signal sees more than one
path to mains earth. An earth loop results causing current to flow between the different earth paths. This condition is
usually detected as a mains frequency audible hum or buzz. To ensure safe and trouble-free operation we recommend
the following:
Use a clean mains outlet for the audio system: Be sure to use a 'clean' power outlet, i.e. one that is
fed directly from the mains, including earth. "Polluted" mains are caused by changing currents on the outlets, such as airconditioners, coffee machines, fridges, computers, dimmer packs etc. DO NOT connect any of these types of items to
the Oxygen 4 main power outlet.
Use star point earthing: It is best to install a ‘star point’ system where the individual earths to the equipment
racks and equipment areas are separately run from a solid central reference earth point.
It is advisable to install several multiple mains connectors close to the Oxygen 4, with a master power switch to shut
down all power to the studio..
Have your mains system checked by a qualified electrician.
Do not remove the earth connection from the console mains plug:
The console chassis is
connected to mains earth through the power cable to ensure your safety. Audio ground is connected to the console
chassis internally.
If problems are encountered with earth loops disconnect the audio cable screens at one end, usually at the destination.
Equipment such as CD players do not have a mains ground connection. In this case the shielding can be connected on
both sides of the connection - a ground loop will not occur. Try to choose a CD player with metal housing.
Avoid induced interference: To prevent interference pickup keep audio cables away from mains power units,
cables and distribution boards, motors, lighting and computer cables and equipment, and any other heavy duty electrical
equipment. Where this cannot be avoided cross the audio and ‘dirty’ equipment cables at right angles to minimise
interference.
Use low impedance sources
such as microphones and line level equipment rated at 200 ohms or less to
reduce susceptibility to interference. The console outputs are designed to operate at low impedance to minimise
interference problems.
Axel Technology srl www.axeltechnology.com
FIRST INSTALLATION
RECOMMENDATIONS
18
FIRST INSTALLATION RECOMMENDATIONS
ENG
Use balanced connections where possible
as these provide further immunity by cancelling out
interference that may be picked up on long cable runs. To connect an unbalanced source to a console input (balanced),
link the cold input (XLR pin 3 or jack ring) to 0V earth (XLR pin 1 or jack ground) at the console. To connect the console
output (balanced) to an unbalanced destination, link the cold output to 0V earth at the console.
Use good quality cables and connectors
and check for correct wiring and reliable solder joints. Allow
sufficient cable loop to prevent damage through stretching.
If you are not sure ... Contact your Axel Technology agent for advice.
9.7
POSITION
The console should be located in a convenient space commensurate with the use to which the console is being put.
Ideally a cool area is preferred not in close proximity to power distribution equipment or other potential sources of
interference. Provision should be made for some flat surface surrounding the console to prevent people using it as a
table top.

12 MONO MODULE
12.1 INTRODUCTION
Each MONO module has two selectable mono inputs which comes factory preset
for Mic (input A) and Line (input B) levels. Normally input A is selected but by
pressing B SEL button the alternative input is selected.
There is a preset gain adjustments for A input with multi-turn control on the rear
panel. The selected A or B source is fed through a common gain trim control
giving a further +/- 15 dB of gain adjustment on the front panel. A jumper is also
available inside the module to apply phantom power to microphone A input.
Mono modules can be fitted with an optional three band parametric equaliser
(ref. MONO-EQ), where the centre band can be swept from 300 Hz to 4.8 kHz.
The signal is routed via a Pan control and the two stereo routing switches to
either the main stereo programme (Master) or the stereo subgroup (Sub).
The PFL switch makes the pre-fade signal available for monitoring.
The Mono module is intended to be connected to Microphone either placed
in the Control Room or in the Studio. Several jumpers allow the user to to route
the TB accordingly to the microphone installation (TB will be set as ‘TB to Control
Room’ when the announcer’s microphone is in the studio and as ‘TB to Studio’ for
use by the producer or the assistant in the Control Room).
A selective ‘muting’ of Control Room or Studio speakers is also provided via
jumper settings. This option is for use with the mic input. When a microphone is
live to air, the monitor speakers in the room containing the microphone will need to
be muted so that there is no feedback.
So, for example, if the mic input is being used for a microphone in the studio, the
studio monitors should be muted.
The module provides also a jumper selectable output to facilitate two relay
closures for On-Air lamp switching on/off.
ALPS N-type 90° ultra smooth 100 mm sliders are provided on series. On
request, to notify at order, ALPS K/VCA series sliders can be also fitted, the last
ones controlling an internal high quality VCA circuitry.

ENG
12.2 MODULE OPTIONS AND JUMPER SETTINGS
The MONO module can be configured in a number of different ways depending on
the jumper options set. The jumpers are situated near to the flat cable connector:
When closed, the A PHANTOM jumper (J 1) allows for Phantom power on Input A.
When using a phantom powered microphone, ensure that the mixer is switched off
when the microphone is plugged in to the XLR connector.
When the C.ROOM MUTE jumper (J 2) is closed, the Fader opening is associated
to the cut-off of the C.ROOM SPK output on the MONITOR module. CUT LED on
the MONITOR Ctrl Room section illuminates accordingly.
When the STUDIO MUTE jumper is closed (J 3), the Fader opening is associated
to the cut-off of the STUDIO SPK output on the MONITOR module. CUT LED on
the MONITOR Studio section illuminates accordingly.
When the RELAY 1 jumper (J 4) is closed, the Fader opening is associated to the
switch of Relay #1 inside the Power Supply. This relay may be used to control an
On Air Lamp (such as MR. LIGHT by Axel Technology).
When the RELAY 2 jumper (J 5) is closed, the Fader opening is associated to the
switch of Relay #2 inside the Power Supply. This relay may be used to control an
On Air Lamp (such as MR. LIGHT by Axel Technology).
When closed, the TB (to) STUDIO-SUB jumper (J 6) put the signal from the prefade section of the module onto the TalkBack (to) Studio audio Bus and allows it to
be output on the Studio Monitor section (see MONITOR module). The major use of
this facility is also that TB STUDIO bus feeds the Telco and Telephone channels
and will therefore allow the Producer to talk to a telephone caller off-air.
When closed, the TB (to) CONTROL ROOM jumper (J 7) put the signal from the
pre-fade section of the module onto the TalkBack Ctrl Room audio Bus and allows
it to be output on the Control Room Monitor section (see MONITOR module). The
major use of this facility is the off-air communication from the Studio (e.g. the
presenter) and the Control Room.

12.3 INPUT REAR PANEL
The A Input is via a standard female XLR-3 connector and it is set for
MICROPHONE sources. The input is electronically balanced and it is factorypreset for around – 60 dB level.
The recessed GAIN A trimmer allows you to adjust in a very precise way the gain
of the ‘A’ source. In conjunction with the GAIN potentiometer (see) this allows you
to adjust the overall gain to any desired figure within the available range.
The A PHANTOM jumper on the PCB (see par. 0) applies phantom powering
+48V to the MIC input A socket for condenser microphones.
WARNING: The Phantom power is used to power microphones with built-in
condenser or electrect preamplifiers. This system requires both conductors to
have the same D.C.potential. So, it’s indispensable that cables and connectors are
balanced and in perfect condition. If these rules are observed, Phantom power can
be applied even dynamic microphones are connected, although it’s preferable to
avoid doing so.
The B Input is via a standard female 1/4” Jack connector and it is set for signals
providing a signal LINE level such as tape machines, RadioMic receivers, ISDN
codecs. The input is electronically balanced and factory-preset for a 0 dB level.
Only one of the two inputs (Input A or Input B) will be active at any time,
depending upon the setting of the A/B switch (see)
An unbalanced INSERT socket (A) is provided which is a break point in the input
channel signal path. The insert point allows external piece of equipment such as
limiters, compressors and other signal processing units to be added as required to
particular input channels.
The Insert is a 3-pole 1/4” Jack Socket, which is normally by-passed. When a jack
plug is inserted, the signal path is broken at a point just after the preamplifier
stage, but before the Input Selection (A/B SEL key). The signal from the channel
appears on the TIP of the plug and is returned on the RING to continue through to
the final output.
12.4 A/B SWITCH
The A/B switch selects the INPUT B (Line) socket when depressed and the INPUT
A (Mic) when released. A LED glows red when the INPUT B is selected.
Both left and right signal paths are fed by the same mono input signal.

12.5 GAIN CONTROL
The GAIN potentiometer provides a variable 30dB range from - 15 to +15dB gain
to match the connected source to the internal 0 dBu operating level
This knob allows you to match the input level to suit a wide variety of professional
and semiprofessional sources. Start with a low setting, especially for professional
equipment, checking the level on the meters using PFL, and increase it if you
cannot reach an adequate signal level with the fader at maximum (refer also to
par. 11.2.
12.6 EQUALISER
The Equaliser (available as an option – MONO-EQ – Ref to Section Errore.
L'origine riferimento non è stata trovata.) comprises four sections. The upper
control provides H.F.(treble) boost and cut of +/-15dB at 13 kHz, and the lower
control provides L.F. (bass) boost and cut of +/-15dB at 60 Hz.
The centre two knobs is arranged as MID frequency section, with a cut/boost
control (lower knob) of +/- 15dB, and a frequency control which determines at
which frequency the boost/cut action will be centered. This MID section, with a
combined frequency range from 300 Hz to 4.8 kHz is particularly versatile for
speech, enabling particular characteristics of the presenter’s voice to be lifted or
suppressed very precisely.
Set the cut/boost control of each section to the centre-detented position when not
required.
12.7 PAN
The PAN control determines the position of the signal within the stereo mix image.
Rotation fully anticlockwise feeds the signal solely to the Left mix bus (Master &
Sub outputs), while rotation clockwise sweeps the image to the Right mix bus
(Master & Sub outputs).
The centre applies 0 dB of gain to both L & R signals.

ENG
12.8 MASTER-SUB ROUTING SWITCHES
The input channel signal may be routed to the main Stereo MIX (MASTER) and/or
to the SUB bus by pressing the respective switches.
There is a red LED inside each switch which will illuminate accordingly. The Sub
mix can be mixed into the main mixbus (Master) (see MASTER switcher on the
Sub module). This is a convenient way to use the SUB assignment as a subgroup
system, creating new possibilities in the console.
12.9 PFL BUTTON
PFL button (operated only in latched) mode allows pre-fade listening (post panpot) of the channel even with the fader closed.
When the PFL button is activated, the channel signal will be connected to the PFL
output and to the MONITOR meters circuitry (see also MONITOR Chapter).
The PFL system is always active and it operates in the ADDITIVE Mode (i.e. You
can listen to one or more PFLs at the same time by selecting one or more PFL
keys).
12.10 FADER
ALPS N-type 90° ultra smooth 100 mm sliders are provided on series.
The scale shows the attenuation. Normal operating position is at the top ‘0’ mark,
providing overall 0 dB of gain.
Fader opening always activates the channel.
On request, to notify at order, ALPS K/VCA series sliders can be also fitted, the
last ones controlling an internal high quality VCA circuitry. There is no audio going
through the VCA faders. VCA faders do not therefore suffer from such severe
noise and signal loss problems that conventional faders may have when wear and
tear causes the resistive surface to deteriorate. The benefit is longer fader life, as
the crackles and dropouts typical of the traditional audio faders are smoothed out.

Each STEREO module has dual switchable stereo line inputs with optional three-band
EQ. Input A comes factory preset for Line, while input B may be set for Line signals
as well for RIAA PHONE signals via internal jumpers, so that a record-player can be
connected directly to the input. Normally input A is selected but by pressing B SEL
button the alternative input is selected.
The signal is routed via a Balance control and two stereo routing switches to either the
main stereo programme (Master) or the stereo subgroup (Sub).
The PFL switch makes the pre-fade signal available for monitoring.
ALPS N-type 90° ultra smooth 100 mm sliders are provided on series. On request, to
notify at order, ALPS K/VCA series sliders can be also fitted, the last ones controlling
an internal high quality VCA circuitry.
Three Start/Stop interfaces are available as an option.
OX4-ST-START
latched Start/Stop on ‘clean contacts’ from slider
OX4-ST-SSIR
momentary Start/Stop relay closures from slider
OX4-ST-2SSIO

13.4 ‘LINE / PHONO INPUT B SETTING
The B Stereo Input can be configured either for Line or Phono sources, depending on the jumper options set on the
input (rear) board.
Phono configuration is suitable for record-players, as a RIAA equalization is featured. NOTE connection is possible
only in unbalanced mode.
Line configuration is suitable for 0 dB level signals (f.i., coming from tape player, tuners, Cd players, etc).

STEREO MODULE
ENG
13.5 INPUT REAR PANEL
The A Stereo Input is via standard female 1/4” Jack connectors. It is electronically
balanced and it is factory-preset for a 0 dB level (LINE sources).
The B Stereo Input is via standard Jack 1/4” connectors. It is set for signals
providing a signal LINE level if not otherwise notified. Via jumper selection (ref to
Section 13.4), an RIAA equalized amplifier can be also fitted so that a recordplayer can be connected directly to the input. Start/Stop control can be also
provided via the 9 pins remote interface (available on request).
When set for LINE signals, the input B is electronically balanced.
When the RIAA option is used with the stereo channel, the turntable connections
should be made via Mono (unbalanced) Jacks – as in the Connections chapter.
Only one of the two inputs (Input A or Input B) will be active at any time,
depending upon the setting of the B SEL switch (see)
13.6 A/B SEL SWITCH
The B SEL switch selects the INPUT B (Line) socket when depressed and the
INPUT A (Mic) when released. A LED glows red when the INPUT B is selected.
13.7 GAIN CONTROL
The GAIN potentiometer provides a variable 30dB range from +15 to +15dB gain
to match the connected source to the internal 0 dBu operating level
This knob allows you to match the input level to suit a wide variety of professional
and semiprofessional sources. Start with a low setting, especially for professional
equipment, checking the level on the meters using PFL, and increase it if you
cannot reach an adequate signal level with the fader at maximum (refer also to
par. 11.2).

13.8 EQUALISER
The Equaliser (available as an option – Ref to Section Errore. L'origine
riferimento non è stata trovata.) comprises three sections. The upper control
provides H.F.(treble) boost and cut of +/-15dB at 13 kHz, and the lower control
provides L.F. (bass) boost and cut of +/-15dB at 60 Hz.
The centre knob is arranged as MID frequency section, with a cut/boost control of
+/- 15dB for frequencies at around 5 KHz.
Set the cut/boost control of each section to the centre-detented position when not
required.
13.9 BALANCE
It adjusts the stereo image of the signal on the stereo line input (i.e. the balance
between the L and R outputs). At the detented centre position the signal routes
equally to L and R.
13.10 MASTER-SUB ROUTING SWITCHES
The input channel signal may be routed to the main Stereo MIX (L-R) and/or to the
SUB bus by pressing the respective switches.
There is a red LED inside each switch which will illuminate accordingly.
The Sub mix can be mixed into the main output mixbus (Master) (see MASTER
routing switcher on the Sub module). This is a convenient way to use the SUB
assigment switch as a subgroup system, creating new possibilities in the Oxygen 4
console.

13.11 PFL BUTTON
PFL button (operated only in latched) mode allows pre-fade listening (post BALpot) of the channel even with the fader closed.
When the PFL button is activated, the channel signal will be connected to the PFL
output and to the MONITOR meters circuitry (see also MONITOR Chapter).
The PFL system is always active and it operates in the ADDITIVE Mode (i.e. You
can listen to one or more PFLs at the same time by selecting one or more PFL
keys).
13.12 FADER
ALPS N-type 90° ultra smooth 100 mm sliders are provided on series.
The scale shows the attenuation. Normal operating position is at the top ‘0’ mark,
providing overall 0 dB of gain.
Fader opening always activates the channel.
On request, to notify at order, ALPS K/VCA series sliders can be also fitted, the
last ones controlling the internal high quality VCA circuitry. There is no audio going
through the VCA faders. VCA faders do not therefore suffer from such severe
noise and signal loss problems that conventional faders may have when wear and
tear causes the resistive surface to deteriorate. The benefit is longer fader life, as
the crackles and dropouts typical of the traditional audio faders are smoothed out.

14.6 HOOK SWITCH AND RING LED
The Hook switch remotely controls the Line hooking on suitable telephone hybrids
(such as Macrotel 5,7,9 and BoxTel by Axel Technology). This switch connects /
disconnects the hybrid from the telephone line and mutes the channel (ie. when
Hook is depressed, Receive input is automatically muted).
The HOOK LED switches on only with telephone line properly connected.
Ring LED blinks when a call (ring) is coming. This requires a suitable control by
the external telephone hybrid (such as Macrotel 5,7,9 and BoxTel by Axel
Technology). Please refer to Telco Remote Interface - par. 0.
If the HOOK switch is pressed with an external hybrid properly connected, the red
HOOK LED will illuminate and the caller is connected to the Telco module but not
yet heard in the broadcast whilst the fader is down.
By opening the fader, the Telco module will be activated and the signal will enter
the program (see also MASTER/SUB switches par. 14.8 and PFL PRIVATE button
par. 14.9)
14.7 PAN
The PAN control determines the position of the signal within the stereo mix image.
Rotation fully anticlockwise feeds the signal solely to the Left mix bus (Master &
Sub outputs), while rotation clockwise sweeps the image to the Right mix bus
(Master & Sub outputs).
The centre applies 0 dB of gain to both L & R signals.

14.9 PFL/PRIVATE BUTTON
Pre-fade listening PFL button (operated only in latched mode) allows a caller to
listen to the talkback mic(s) and to be heard without being in the broadcast (i.e.
with the fader closed).
When the PFL button is activated:
- the channel (Receive) signal will be connected to the PFL output and to the
MONITOR meters circuitry (see also MONITOR Chapter).
- the TalkBack To Studio bus audio is automatically switched to the caller for “offair” (i‘Private’) communications with the engineer or the announcer
It means, the presenter can talk off-air with a caller (whilst the Main programme
is being output) via its own microphone (routed as TB to Studio – see par. 0) or
the TB microphone built-in into the Monitor module (see par. 17.7 for TB built-in
microphone activation).
The PFL system is always active and it operates in the ADDITIVE Mode (i.e. You
can listen to one or more PFLs at the same time by selecting one or more PFL
keys).
When the PFL button is deactivated:

17.2 MODULE OPTIONS AND JUMPER SETTINGS
There are four Jumpers on the Monitor module PCB.
J1 and J2 are situated on the top of the module (near to the Tuner potentiometer)
J3 is situated near to the ‘flat cable’ connector (behind the Ctrl Room speaker
potentiometer)
J4 is situated behind the Control Room SUB switch.
The jumper settings are given below:
The J1 and J2 jumper settings allow you to configure each of the left and right
outputs of the back-panel STUDIO outputs to either Line level (i.e. suitable for an
external amplifier) or to headphone level (ref par. 0).
When closed, the TB MIC jumper (J3) enables the console built-in microphone for
TalkBack to Studio communications.
When the jumper J4 is closed, the TalkBack to Studio button is associated to the
cut-off of the C.ROOM SPEAKER output on the MONITOR module.

17.3 REAR PANEL CONNECTIONS
Oxygen 4’s rear panel contains the following connections:
TUNER
These 1/4” plugs contain the balanced stereo External Input for the Studio and
Control Room listening.
CR / STUDIO SPEAKER / HEADPHONES
The Oxygen 4 contains 2 headphone output jacks (Studio and Control Room) on
the front panel.
On the back panel, Control Room output is factory-preset for connection to audio
power amplifiers associated with a pair of monitor loudspeakers**, while the Studio
output may be set as secondary Headphone output or as Speaker output (via an
external amplifier).
The simplest way of using the Studio headphone output is therefore simply to plug
a pair of headphones into the front panel jack.
For improved system flexibility, it may be convenient to set back panel output as
an additional Studio headphone output. Settings are done via two internal Jumpers
on the PCB (ref to previous paragraph).

17.5 STUDIO MONITOR SECTION
Signals to be monitored by the studio monitors and / or headphones (see Jumper
J 1 and J 2 - par. 0) are selected by using the buttons at the top of the panel. They
can be used to select Master (MST) or Tuner sources, as well as PFL bus.
The PFL switch allows the normal monitor source to be interrupted and the PFL
signal monitored in its place.
In particular, when the PFL button in the Studio section is pressed but no PFL
signal comes from the input modules, the Studio outputs still reproduce Tuner or
Master signals. You may regard this as the PFL routing circuit being armed but not
active. To make it active, the PFL must be engaged in at least one of the input
modules.
The STUDIO rotary control will affect the output to any headphones connected to
the 1/4” jack STUDIO phones socket at the bottom of the module as well as the
Speaker/Headphones Studio output on the rear panel.
The CUT LED is lit whenever the mute function (on Studio speaker only) is active
(ref to MONO Module settings - par. 0) *. For normal Studio speaker operation the
mute LED must not be lit.
* Speakers full muting may be required when a “live” microphone is located in the
Studio.

17.6 CONTROL ROOM MONITOR SECTION
The Selection To Meter button determines what is shown on the Monitor meters.
When the button is released, the PFL signal only is shown at the meters.
With the button pressed and the LED illuminated, the levels of Tuner, Master or
Sub signals can be displayed, depending on the selected source in the Control
Room Monitor section. For example, if Selection To Meter is selected for the
meters, and the Control Room has Tuner selected, then the meters will display the
Tuner signal.
Switches at the bottom of the section allow selection of one (or more) of the four
Tuner, Master, Sub and PFL signals as the Control Room source.
The PFL switch allows the normal monitor source to be interrupted and the PFL
signal monitored in its place.
In particular, when the PFL button in the Ctrl Room section is pressed (Red light
illuminated) but no PFL signal comes from the input modules, the Ctrl Room
outputs still reproduce Tuner / Master / Sub signals. You may regard this as the
PFL routing circuit being armed but not active. To make it active, the PFL must be
engaged in at least one of the input modules. When PFL is active, the LEDs inside
Master, Tuner and Sub buttons turn off.
Two smooth-feeling rotary controls allow the levels to be separately adjusted on
the Headphones plug (at the bottom of the module) and on the Speaker output
(back panel).
The control room CUT LED is lit whenever the mute function (on Ctrl Room
speakers only) is active (ref to MONO Module settings - par. 0)**. For normal
control room speaker operation the mute LED must not be lit.

18.1 FRONT VIEW
18.2 REAR VIEW
18.3 DESCRIPTION
The Oxygen 4 Power Supply (PWS) consists of a power transformer, selectable for 115 VAC or 230 VAC operation,
rectifiers, filter capacitors and voltage regulators on a circuit board.
The power supply is protected by a replaceable AC mains fuse located in the power entry socket plus internal fuses on
the transformer’s secondary outputs and self-protected current-limiting regulators.
The power supply has three output voltages:
- +/-15 volts for the audio circuitry
- +48 volts phantom for condenser microphones.
Three LEDs on the front of the unit indicate whether the power to the three voltage rails is being supplied correctly. if one
of the LED’s fails, then there is a problem with the PWS unit or the console. Ref to par. 18.7
The power supply should be installed where there is adequate ventilation for heat to circulate from the rear and the side
of the unit. In the event of PWS rack-mounting, other equipment in the rack which is known to produce a significant
amount of heat should be mounted not closed to the unit (i.e. some space should be provided between these and the
Oxygen 4 Power Supply).
The PWS may be rack-mounted through the supplied supports.

POWER SUPPLY
18.4 PWS RELAYS
The power supply features two built-in relays separately controlled by the MONO
modules.
They are designed to illuminate external Studio and/or Control Room Warning/On
Air lights (such as Mr Light by Axel Technology) showing that one or more
microphones are ‘on air’.
Relays are intended for low voltage electric loads (e.g. 24 V), up to 10 A.
FOR SAFETY AND TO PROTECT THE OPERATOR FROM HIGH VOLTAGE
SHOCK, NEVER CONNECT AC MAINS TO PWS RELAYS.
Use relays to directly control low-voltage lamps or to drive 220 / 115 Vac Lamps
via external relays or optocouplers.
The Oxygen 4’s PWS relays feature either Normally Open or Normally Closed
contacts. Two LEDs on the front of the unit indicate whether the relays are closed.
18.5 MIXER CONNECTION
A cable with a 9 pins subD plug on each end comes with the console. It is used to
connect the power supply to the mixer.
Plug the cable into the power supply MIXER CONNECTION socket. Press the
plug into the socket, and screw on the locking ring to hold it firmly in place. Plug
and secure the other end into the console PWS socket on Monitor module.
Turning the Console On or Off: First check that the mains and DC leads are
correctly plugged in and secured. Turn on the power supply using its rear panel
mains switch. The console must be connected to the power supply before turning
it on. To avoid loud pops in the speakers make sure that the connected power
amplifiers are turned off before switching the console on or off.

18.6 MAIN AC VOLTAGE SETTINGS
Before connecting the Oxygen 4 to mains power, determine the actual mains
voltage and confirm that the Oxygen 4 has been configured correctly. As could be
expected, an incorrect mains configuration could seriously damage the unit.
If the unit is to be used with a mains voltage different to that for which the unit is
supplied, set the voltage change-over switch, which is placed inside the box,
closed to the AC socket and the AC filter.
The power supply socket has an integral fuse drawer containing the AC power
fuse and a spare, both of the same value, rated at 500 mA T for 220/230 V AC and
for 110/115 V AC tensions.
Make sure that the IEC mains plug is pressed fully into the MAINS INPUT socket.
WARNING: The power lead must be disconnected before attempting to remove
the panels or cover. Removal of the panels and cover can expose dangerous
voltages.
18.7 PWS TROUBLESHOOTING
The correct operation of power supply is showed by the 3 LEDs glowing on the
front panel. If the console doesn’t work properly, please check the power
connection cable.
If the neon lamp inside the Main switch is off (and therefore all LEDs on the
power supply front panel are off), please check the Main Fuse next to the mains
cord socket (500 mAT).
To do this:
-
Switch the ON/OFF switch to the OFF position
Remove the mains cord from the connector
Use a small screwdriver to extract the fuse carrier drawer from its location
closed to the connector
Check the fuse and replace if necessary;
In the event of repeated failure of the mains fuse consult the Axel
Technology technical support or Yr local dealer
.
If one or more LED on the panel of power supply are switched off (and therefore
console doesn’t work properly) please execute the following steps:
-
disconnect the console from the PWS
switch the PWS on
verify that every LED on the front panel glow (except Relay 1 and 2)
Axel Technology srl www.axeltechnology.com

METERBRIDGE
ENG
19 METERBRIDGE
19.1 VIEW
19.2 DESCRIPTION
The Oxygen 4 mixer is fitted with VU / PPM meters.
VU meters respond to an average signal level, whereas PPMs respond to peak changes (The PEAK LEDs are activated
by the shortest transient peak, but remain ‘on’ long enough to provide easy recognition).
If a 1kHz sinusoidal signal is input to the mixer and the amplitude adjusted such that the level at the master output is 0
dBm, the meters will read 0 VU (the orange LED will glow).
The VU meters are factory-calibrated and no further user adjustment is allowed. PPM reading may be disabled (ref to
next Section).
A short cable with a 9 pins subD plug on each end (male and female) comes with the console. It is used to connect the
meterbridge to the mixer.
The LEFT pair of meters display PFL stereo signal, while the RIGHT pair display the Master signal.
The LEFT pair of meters can be also altered to show any combination of the Master output, the Sub output, Tuner input
or whatever is selected on the Control Room section of Monitor module when the “SELECTION TO METER” button is
pressed.
For example, if SELECTION TO METER is selected and the CONTROL ROOM has SUB selected, then the meters will
display the SUB signal. Of course, meters will also display the PFL signal, if PFL button is selected (see par. 17.6)
19.3 METERBRIDGE SETTING
PPM reading can be disabled via the Jumper J5 situated on the LED board inside the meterhood, behind LEFT
/MONITOR scale.
VU (average) reading can never be disabled.
