1 Introduction

The VAM is intended as a general-purpose device that can be used to interface audio devices that are not
directly compatible with each other. The application for which the module was originally conceived is the
connection of an aviation headset to a Flightcell Iridium Sat phone cradle; this application is used as an
example later in this document and this is reflected in the terminology that is used.

As well as matching impedance and voltage levels, the VAM is capable of providing microphone bias voltage
(which is typically required when connecting to a high-impedance headset), galvanic isolation between input
and output, and sidetone.
