Altair 4W2-200 - 4/2-wire universal interface
Allows connection to third-party 4-wire-4W intercom systems and non-compatible systems or connection to standard telephone line.
4/2-wire universal interface. Allows connection to 4-wire-4W third party intercom systems and to non-compatible systems or connection to standard telephone line. It is a key element when connecting ALTAIR intercom systems to different non-compatible devices such as professional camera CCUs or non-compatible intercom systems.
This small unit converts the "bidirectional" signal of the Intercom line (2 Wires) into two unidirectional signals (input/output) through a 4-pin connector. In this way, through the use of this interface we will be able to "inject" signals from non-compatible devices to the Intercom system. In addition, we can extract the intercom signal for various uses such as recording, production, public address, etc..
The level of each of the signals (input/output) can be adjusted within a wide range, facilitating interconnection with a wide range of products on the market. Alternatively, the unit can work as a "telephone hybrid", connected to a telephone line to receive or generate telephone calls to the entire Intercom System.
