1.�INTRODUCTION
Thank you very much for expressing your confidence in LTO products by
purchasing MS series powered monitor speaker system. The MS series monitor
are specifically designed for using in hi-quality performance site and the precise
sound commercial place. It includes three small and compact stage monitor
models (MS8MA, MS10MA, MS12MA) This series uses trapezium configuration
which greatly decreases the resonance of the standing wave in the cabinet.
These cabinets uses hi-density matrix spray-paint technics and the bottom
bracket design which make mounting quickly and flexibly. HF compression driver
and vented LF for fully professional performance.
The MS powered monitor speaker cabinets include some exclusive innovations
such as switch mode power supply and digital power circuitry (in selected modes)
that make them the lightest powered cabinets of this kind ever made. The MS
full range models include another Alto innovation: The MODELLER. Thanks to this
circuitry user can select 16 different tastes and applications.
MS powered Monitor speakerEnjoy your and make sure to read this Manual
carefully before operation!
