Echipament sonorizare Clear-Com PL-PRO EF-1M

DESCRIPTION

CONNECTING A PARTY-LINE CHANNEL TO A MATRIX FRAME PORT

An EF-1M Interface can connect a channel of standard or TW party line directly to a

Clear-Com Matrix (MX+3, MX+2) frame port, allowing the party-line intercom to be located at quite a long distance from the Matrix frame. At the same time, the EF-1M

interfaces a DC-voltage call signal or 20-kHz call signal to the Matrix.

The EF-1M is recognized by the Matrix as a Clear-Com CCI-22 Interface. It provides the

same function as the CCI-22 Interface with the following exceptions:

• the EF-1M supports only one channel.

• the EF-1M also supports the 20-kHz call signal protocol.

• the EF-1M is a stand-alone unit and does not require an interface frame.

NOTE: The EF-1M must be powered from the party-line connection
