13TELEPHONE CONNECTIONS (OXYGEN 3 and 3 ST)
The Telephone module features a built-in telephone hybrid.
The audio sent to the telephone caller is a mix-minus (N-1). The mix minus signal is the programme output
signal with the phone signal (caller’s voice) removed.
DO NOT CONNECT this appliance to ADSL telephone lines, even if filtered.
DO NOT CONNECT this appliance to digital Telephone lines
MAKE SURE this appliance is connected to POTS, analogue lines
In order to avoid any Hum and for EMC reasons, the system must be earthed via earthing screws on
the rear panel.
This appliance is connected to telephone networks indirectly through interface (in-house telephone
exchange / PABX). Direct connection to the public telephone net is under sole responsibility of the
user.
RJ11 socket will accept 4 conductor modular plugs, but only the 2 central pins (number 2 and 3) are typically used:

This unit allows the connection on parallel of a standard telephone set (for dialling services). Please note that „Phone‟
socket is always active (i.e. it doesn‟t depend on the „Hook‟ button state) and it has the same Pin-Out as the LINE socket.
Should the device be put out of action due to being struck by lightning or excess voltage, disconnect
it from the telephone line 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.
Other connections:
R/L (OUT REC on PIN RCA): double mono output which allows recording of the telephone calls (either SEND or
RECEIVE signals).
CALL (terminal board connector): connector for external call signalling. A photocoupler inside the module closes when a
telephone call comes (ring).
NOTE: Typical current allowed on the photocoupler: 5 mA (max 10 mA). Max voltage allowed: 15 V.

14.1 MASTER OUTPUTS
The Oxygen 3‟s Master section gives the operator an extensive set of resources.
In addition to two Master balanced outputs (Out 1 and Out 2, carried on DB15 female connector), provision has been
made for an unbalanced, level-controlled output on PinRca connector (Out 3), an unbalanced, fixed level on PinRca
connector (Fixed) and two Mono outputs (summing the left and right channels and dropping the level by 6dB). All the
Master outputs provide the same Master signal.

14.2 MONITOR OUT AND EXT-IN CONNECTIONS (OXYGEN 3 AND 3 ST)
The Oxygen 3‟s Monitor section gives the operator an extensive set of resources.
In addition to monitoring the Master and PFL audio buses, provision has been made for monitoring an external audio
source. This stereo input (Ext-In) is intended to be connected to microwave, FM or satellite receivers or another studio.
MONITOR output is a stereo line-level output, provided for connection to a power amplifier associated with loudspeakers.
A selective „muting‟ of Monitor speakers is also provided on series. When microphone 1 is live to air, the monitor
speakers in the room containing the microphone will be muted so that there is no acoustic feedback.
Oxygen 3 and Oxygen 3 ST come from the factory with Muting facility associated to Slider opening on Channel
1. On request, this facility may be extended to Input channels 2 and 3, too (by means of regular slider
replacement –ref to par. 10 - Options)
The slider opening on Channel 1 is also associated to a photocupler closing on TB (TALKBACK) SubD 9 pin
connector. This photocoupler may be used to control an On Air Lamp (such as MR. LIGHT by Axel Technology).
