7.2 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. 3 - 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).
