Overview

This manual covers the family of optional Headset Jackbox models manufactured by

Zetron and used to interface standard headsets and handsets to Zetron console positions.

The jackbox offerings can be divided into two groups, based on the connector type used

by the headset. The configurations supported are:

• Dual-prong connector Headset Jackbox types

• Jackbox with no volume knob part number 950-1175

• Jackbox with single volume knob part number 950-1082

• Jackbox with dual volume knobs part number 950-1077

• XLR type connector Headset Jackbox types

• Jackbox with no volume knob part number 950-1187

• Jackbox with single volume knob part number 950-1185

• Jackbox with dual volume knobs part number 950-1186

The dual-knob version is usually employed in systems where the console positions handle

both telephone and radio traffic. The single-knob version is typically used where the

console positions only handle telephone or radio, but not both at once. The no-knob

version is for use in systems where the volume for various audio sources is adjusted by

means of a control that is part of the console graphical user interface (GUI).

The following figure shows the dual-knob jackbox. (The front panel view on the left; rear

panel view on the right.) The single-knob and no-knob jackboxes are identical except the

absent volume knob positions are filled by a plug. The knobs are not labeled until after

installation, at which point their actual purpose is known.
