AU stations thatselect the Channel 1 pushbutton will talk and listentogether. AU stations that select the Channel 2pushbutton will talk and listen together, and so on.The front-panel channel select buttons control bothtalk and listen functions. The -CL ption p r o walternate action switches wbich stay on when pressedin and turn off when p r d ut. Becausemore thanone channel may be sekcted at a time (withoutcrosstalk), a Model 810B-CLuser station can talk andlisten to other 810B-CL user stations on up to 10channels. Theblock diagram for this system is showninF i e -3A.

Each conference channel should be terminated w200 Ohms. The termination requirements for tsystem are show in Figure 3-3H. See F i e 3-for linepinwdipatim333 SlOB-cL Intereomectiontom' systemIt is poshible to interwnnecta wnference style systwith an RTS TW ntercom System. This is shownFigure 3-33. A transformer and a DC blockicapaator is required for each chauael. An alternconfiguration would be to umuec! only some of tModel 810B chanuek to the "IW Intercom" systeleaY the others free for communications betweMode 810B stations only. In this case, he channthat are not conneded to the TW System mustterminated with a 2W ohm 114watt resistor. Connthis resistor aaoss the balanced audio as shownF i e Xi.
