The TBP16 is the main unit of a handsfree system for professional communication, composed by a intercom TBP16 and from a maximum of 16 remote intercom stations EL4400/S.
The system is proper to be used during the production of films and television programs but it can be employed for comment, dubbing and any other purpose.
The TBP16 has an IFB input (interrupted feedback) to be able to listen the audio signal of the program in processing that is interrupted when begins the conversation with one of the EL4400/S stations.
The TBP16 is normally installed in the control room or in the comment/speaker room and all the EL4400/Ss in the various connected rooms (for instance editing rooms).
The start of the connection among a station EL4400/S and the TBP16 it is executed pressing on the "TALK" lever switch present on the EL4400/S; to happened connection, the corresponding led on TBP16 is on, if in this circumstance, another intercom activates the lever switch "TALK", the corresponding led on TBP16 flashes but the connection is not activated, the second EL4400/S remains in stand-by up to when the first conversation is not completed.
The principle of functioning is based on a priority system, the EL4400/S linked to the connector number 1 has the highest priority, the number 16 that lowest. If the EL4400/Ss that activate an request are two, the EL4400/S with lowest priority has to attend the end of the conversation of the EL4400/S with highest priority The connection with the stations EL4400/S happens through particular XLR connectors with which it has been possible keep down the height dimension of the TBP16 in only 2RU 19."
The connection among the TBP16 and the EL4400/Ss, is FULL DUPLEX and HANDSFREE; for a correct operation it is necessary to regulate the potentiometer set on the anterior panel of the central intercom (TBP16) so that among the interlocutors happens.a communication without interruptions.
The TBP16 is endowed with a particular circuit anti Larsen to eliminate the reentry of the signal audio among loudspeaker and microphone.
The optimal position of the potentiometers must be retouches in the case in which there is a notable difference of noisiness in the environments where are placed the intercoms.
