Partyline systems (or two wire systems) such as the axxent system are used mostly in the audio and light system rental business and four wire systems mostly in broadcast applications. Often, a connection between these principally different systems is wanted. In addition to intercommunications, the new interface FW100 allows visible call signals (tally) from and to the systems. Connection to the partyline side is by two 3 pin xlr connectors – the same as with any call signal light or a belt pack.
In addition, two unshielded wires allow the signalization from the four wire side by a contact switch. Signalization from the partyline system is by two wires and a pulse signal of approximately 1.5 volt that could trigger a relay or a contact. Also, the call signal is indicated on the adaptor by an led.
Interconnection DB9 cable is is not a standard accessory but may be ordered separately.
Features
- built solidly in a compact steel case for long lasting use
- Possible echo caused by the interconnection of the system can be nulled by three potentiometers on the front side of the unit
- Level control to and from the systems is by switches and potentiometers – also on the front
- The optional cable has no xlr connectors soldered because connections of four wire systems are widely different
