Introduction
The Xmic is an advanced, electronic ground microphone designed to amplify the
noise generated by water escaping from buried supply pipes under pressure. By
means of identifying the position of the loudest leak noise indicates the position
of the actual leak itself.
The Xmic system comprises a lightweight portable amplifier module complete
with battery charger, a pair of aviation-quality 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 portable amplifier module has an LCD display and the advanced, easy-to-use
features of the Xmic enable the operator to pinpoint leaks faster and with more
confidence than ever before.
Note
: The headphones supplied with the Xmic cannot be interchanged. The
impedance of the headphones is matched to the Xmic control unit during
manufacture.
