Jands E-400 Ezicom Talkback Master

The Jands Ezicom E-400 headset intercom master station is designed to meet communication needs in contemporary stage productions, particularly where high ambient noise levels may be experienced. A basic system would consist of one E-400 master station connected to a number of remote E-100 or E-300 substations.


 Up to 20 remote E-100 or seven wall-mounting E-300 substations can be connected to one E-400 master station

 Up to 100 remote substations may be run in a system which uses multiple master stations to supply power

 Connection between the master station and the substations is via standard two-core screened microphone cable
