Clansman Audio Gear Staff User (AGS) Headset

There are a large number of different microphone and headphone sets available for the Clansman radio system. The ‘Audio Gear Staff User’ or AGS headset was designed for use in command posts where there was need to be able to switch from listening to the radio net to listening to spoken instructions within the vehicle or command post and back again quickly without removing the headset. The Clansman’s advertising manual at the time described the headset as:

This maximum comfort headset has been designed for use by troops and other military personnel engaged in areas of continuous or intermittent noise where headsets have to be worn with seperately issued protective helmets. The “SONOVALVE II” allows users to listen to local conversations or use the telephone without removing their headsets.

The headset is attached to a long lead, with a standard multiple pin plug on the end that attaches to most of the different radios in the Clansman series, except for the 349:
