Talkback24 Mainframe
Talkback 24 is a twenty four square matrix, four wire talkback system. It is PC programmable, includes full IFB facilities, and can support any combination of talkback panels and four wires, up to a maximum of twenty four. The Talkback24 may be used in conjunction with our CT800 camera talkback switcher to additionally support eight cameras. All panels include a volume control for each key as standard.
The system is based around our remarkably small 1RU mainframe, with a depth of only 375mm. The unit has front panel D9 PC access along with a lcd display and pushbuttons for easy adjustment of matrix input, output and IFB through levels.
Port connections on the rear of the unit are D9 for both four wire and panel ports. Each port has a support card within the frame which defines it as a panel or four wire. The system will accept any combination of panels or four wires up to it's maximum of twenty four. Every four wire port includes full IFB facilities, with separate IFB inputs. System inputs are not lost when IFB facilities are used. The Talkback24 is fully programmable via it's Windows (TM) interface. All sources and destinations for panel keys and volume controls may be setup as required. Individual keys and volume controls may be grouped to talk and listen to a number of source/destinations. Ports may be named and will be displayed on panels supporting labels. Four GPI (relay) outputs are available and programmable. Eight dim groups are supported for multiple panel dimming. Ports may be forced open to selected destinations for generating open production talkback.
