Intercom units provides an interface between two channels of 2-wire party-line intercom audio and two channels of 4-Wire analog line-level signals
The COMMS 300 and the openGear® version, Intercom units provide a means to interface between two channels of 2-wire party-line intercom audio and two channels of 4-Wire analog line-level signals. The unit is capable of performing auto nulling for each channel with the push of a button. In addition, each of the 4-Wire input and output channel levels are monitored and displayed on easy to understand front panel VU meters. With the flip of a switch, the unit can be a +28VDC party-line voltage power source while providing the 200-ohm intercom audio termination on both channels. If so desired, the party-line source and termination can be removed by just flipping the switchback. The unit can also be configured to work with either RTS party-line or Clear-Com party-line equipment with the flip of a front panel control switch. This switch adjusts the output gain between the party line circuitry and the 4 Wire line-level circuitry depending on which type of units one is interfacing with Auto nulling is done to achieve maximum return loss between the 4 Wire input and the 4 Wire output channels.
The Intercom unit contains four 5-segment LED VU meters on the front panel. The first set displays the 4 Wire input levels for Channel 1 as well as the 4 Wire output levels for Channel 1. The second set of VU meters display the input and output levels associated with Channel 2. The OG-Comms is fully openGear compatible, an industry-standard card frame, fully SNMP controllable and monitorable through DashBoard industry-standard software. The openGear frame also offers redundant power supplies. By adding the MultiDyne OG-Comms Audio fiber transport card, a party-line can be extended over fiber.
