INTRODUCTION

Thank you for purchasing a Martin Audio LE Series monitor. LE Series
monitors have always set the industry standard for touring and stage
applications.  All monitors except the LE400C utilise differential dispersion
horn technology to define a high frequency coverage footprint that is
particularly useful for stage monitor applications.

UNPACKING

Each Martin Audio loudspeaker is built to the highest standard and
thoroughly inspected before it leaves the factory.   After unpacking the
system, examine it carefully for any signs of transit damage and inform 
your dealer if any such damage is found.  It is suggested that you retain 
the original packaging so that the system can be repacked at a future 
date if necessary.  

Please note that Martin Audio and its distributors cannot accept any
responsibility for damage to any returned product through the use of 
non-approved packaging.

3 OVERVIEW

The LE Series products covered in this guide include the LE350A, LE12J,
LE400C and LE700A.  All except the LE400C feature differential dispersion
horn technology.  A differential dispersion horn varies its horizontal
dispersion from wide to narrow as a performer moves back from the
monitor.  This narrowing dispersion effectively changes the forward gain of
the horn which enables the horn to throw further, increasing the operating
range of the monitor and reducing excess spill.

For optimum performance, it is recommended that the LE Series monitors
in active mode are used with the MX5 System Controller or an appropriate
digital controller such as the Martin Audio DX1.  Please refer to the
appropriate controller user guide for information on connections and correct
limiter settings.
