To request to the moment of the order it is possible to ask for:

Thanks to the use of particular XLR panel connectors, it has been possible to contain the dimensions of the TBP4 in a container only 1RU 19" tall.
This, togheter with low consumption and the possibility of 12 V or 24 V power supply, make the TBP4 a versatile instrument for use both in studios and in vehicles for outside broadcast.

TBU - Telephone Balance Unit

The TBU (Telephone Balance Unit) provide high degree of separation between send and receive signals, enabling 4-wires communications system to interface with the telephone network.
In telephone IFB applications, the high drive capacity at the 4-wires output, enables a presenter’s earpiece to be connected directly to the unit without an external amplifier.

Features

To enable communication between the 4-wires circuit and the telephone network, the 4-wires an line connections are made to the unit and the “hook” switch is pressed to power the unit from the line.
This will be indicated by the ON LED, and can either be done after an outgoing call has been dialed on a telephone set connected to the unit, or to answer an incoming call after RING LED is seen flash (a telephone set is not required for incoming calls unless an audible ring is required).
If the sidetone level at the 4-wires output is found to be excessive, the outgoing signal level should be reduced or the balance controls adjusted to minimize it.
To ensure compatibility with all systems, a switch is provided to select either the inner or outer pair of conductors on the RJ11 connector.

4WBB is compatible with similar apparatuses of other brands in commerce.
