The TEL1S from Bogen is a Telephone Input Module for the Power Vector amplification system. This module requires an external power supply for loop start or ground start trunk interfacing. The dry loop interface can be used for audio-activated paging.
The module has a 6- pin screw terminal input barrier strip connector to make the input connection. The module provides for the connection of an external talk-battery power supply of 48V DC. The module also has a gain control that will allow the gain to be adjusted from 0 dB to 30 dB. It has he ability to mute lower priority modules and be muted by higher priority modules. The module is able to assume any of 4 priority levels. The module has a VOX/gating circuit to control muting of lower priority modules and its internal gating circuit with controls for threshold and duration. It has a built in limiter, with a threshold control, to limit the maximum output level of the module. The module’s output is assignable to either or both of two mixing buses.
