IP-Intercom Stations: Front Panel
The rackmounted Livewire IP-Intercom stations in-
corporate a number of front panel connectors, controls
and indicators to allow the operator to operate the system
quickly and confidently. Front and rear panel views are
shown for the 20-station OLED display and the 10-sta-
tion film-cap user-legendable stations. The Element con-
sole versions of these stations incorporate the same con-
trols in slightly different physical layouts.
Front Panel Connectors
Microphone Jack
This jack is used for a panel-mount microphone with
a 1/4 inch Tip-Ring-Sleeve connector. One popular inter-
com microphone is the Telex MCP-90-8.
