On the OXYGEN 3000 DIGITAL Console it is possible to connect a maximum of 4 Talk boxes.
Every Talk Box is phisically connected with a Mixer MIC-source.
MIC2-> TB2
MIC3-> TB3
MIC4-> TB4
MIC5-> TB5*
MIC 5 works as a LINE input. It is designed to be a Telco input also.
Each Talk Box has two buttons corresponding to two GPI and lamps corresponding to two GPO. The two GPI correspond to ON AIR button and
Talkback:
ON-AIR Button
The ON-AIR button works parallely with the ON/START mixer button.
If the MIC is in ON state on the MIXER, it is possible to disable the MIC from the Talkbox and vice versa. The GPI is in the RJ45 MIC connector.
ON AIR LIGHT - MIC
The MIC ON-AIR light reflects the MIXER ON/START BUTTON. When the Channel is in ON state the MIC ON AIR light is on, when the Channel is in OFF
state the MIC ON AIR light is off. This GPO is in the RJ45 MIC connector.
ON AIR LIGHT -STUDIO
The STUDIO light reflects the logical operation (OR) between all Studio Microphones. If either or all the Studio Microphone/s is/were ON the light
should be on, the light should be OFF only when all Microphones are OFF.
This GPO is in the RJ45 MIC connector.
TB Button
On each Talk Box, the TB button pressure sends the related mic signals to the Control Room SPEAKERS/HEADPHONES.
The TB button works in an impulsive way. When the TB button pressure stops also the communication with the Control-Room wll be stopped.
If you have a Talk Back signal, speakers or headphones will stay connected with the MIC source until you stop the TB button pression.
