Zetron Headset Jackbox 6 025-9632B
Overview Introduction 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.
Introduction Figure 1. Dual-knob Headset Jackbox FRONT CHASSIS GND PRIMARY EXPANSION 1 10 MIN VOLUME 1 MIN VOLUME 2 REAR Headset Jack The headset jackbox is available in versions supporting both the industry standard dualprong headset/handset plugs and XLR type, 6-pin microphone plug connectors. Primary and Expansion Ports The Primary port is used to connect to the Headset port on a Zetron console position using a shielded 8-conductor RJ45 patch cable (recommended Zetron part number 709-7889).
Glossary Glossary The following terms are defined for their use in this manual to avoid confusion. Term Definition Ear 1 Ear 2 These refer to the two audio channels supported in the Zetron Jackboxes. Because the audio channels are configurable, “Ear 1” and “Ear 2” are used as generic terms. Headset or H/S Headset is used to refer to either a headset or handset plugged into the Zetron Headset Jackbox. Off Hook On Hook These terms refer to the state of the telephone.

Headset Jack Connections This chapter describes the purpose and pinout information for each connection port on the Headset Jackbox. Headset Jack Dual-prong Jack The dual prong headset jack is configured for the industry standard pinout for a connection of this type. It supports 4-wire (ear and mouth), and 6-wire (ear, mouth, and PTT) monaural headsets.
Connections XLR Jack The XLR headset jack is configured as shown in Table 2. It supports 4-wire (ear and mouth), and 6-wire (ear, mouth, and PTT) monaural headsets. Figure 2: The XLR Jack Pin-out Table 2: The XLR Jack Pin-out Pin Signal 1 Ground (GND) 2 MIC + 3 MIC - 4 EAR+ (1) 5 EAR+ (2) + 6 PTT Primary and Expansion Ports There are two RJ-45 jacks on the rear panel of the jack box labeled Primary and Expansion.
Chassis Ground Lug The Expansion jack is used to connect multiple jackboxes in parallel. Again, a shielded 8-conductor RJ45 patch cable (recommended Zetron part number 709-7889) is used for this. The cable plugs into the Expansion port on the first jackbox and into the Primary port on the parallel jackbox. In theory, more than two jackboxes can be daisy-chained together, but the audio level will decrease as each jackbox is added.

Switches Configuration Switches The overall behavior of the jackbox is configured with the 10 DIP switches located in the center of the rear panel. The following table lists the functions of the various switches and indicates the default settings configured at the factory. Table 4: Dual-knob/Single-knob Headset Jackbox Switches Switch Function Down Up 1 Jack sense Jack sense enabled * (Headset presence detected by headset jack connected.
Configuration The volume knobs on the single- and dual-knob jackboxes can be configured as shown in the following table, but typically they should be left at their factory defaults.
Setting Audio Levels The following procedure can be used with either one of the Min Volume pots. You will need a small flat-bladed screwdriver or pot adjustment tool to adjust the pots. • With the rear panel minimum volume control rotated fully clockwise (when looking at the rear panel), the minimum volume level obtainable with the front panel control will be about 20 decibels below the maximum volume.
