TEL1S Bogen Input Modules

The TEL1S module shall have a transformer-isolated, balanced input and configuration jumpers that will allow it to interface with both wet and dry loop telephone systems. In the dry loop mode, this module shall allow connections to page port systems. In the wet mode of operation, it shall allow connections to both ground start and loop start telephone systems. The module shall have a 6-pin screw terminal input barrier strip connector to make the input connection. The module shall provide for the connection of an external talk-battery power supply of 48V DC. The module shall have a gain control that will allow the gain to be adjusted from 0 dB to 30 dB. It shall have the ability to mute lower priority modules and be muted by higher priority modules. The module shall be able to assume any of 4 priority levels. The module shall have a VOX/gating circuit to control muting of lower priority modules and its internal gating circuit with controls for threshold and duration. It shall have a builtin limiter, with a threshold control, to limit the maximum output level of the module. The module’s output shall be assignable to either or both of two mixing buses.
