HWM DXmic User Manual page 3

The DXmic is an advanced, electronic ground microphone designed to amplify the noise
generated by water escaping from buried supply pipes under pressure. Identifying the position
of the loudest leak noise indicates the position of the actual leak itself.
The DXmic system comprises a lightweight portable amplifier module complete with battery
charger, options of wired or wireless (Bluetooth) headphones and an acoustically shielded
ground microphone foot. As an optional extra, a hand-held listening probe is available. This
comes with a tripod foot and two probe rods for sounding in soft ground.
The DXmic has a touch screen LCD display and the advanced, easy-to-use features of the
DXmic enable the operator to pinpoint leaks faster and with more confidence than ever before.
