1. INTRODUCTION
Thank you for your purchasing LTO MS series passive speaker system. This
series includes MS series cabinet and LTO MS1 speaker modeller.
The MS series speaker cabinets are specifically designed for using in hi-quality
performance site and the precise sound reinforcement commercial place. It
includes five full-range cabinets (MS12, MS15, MS152, MS153, and MS154)
and two subwoofers (MS15S, MS18S). This series uses trapezium configuration
which greatly decreases the resonance of the standing wave in the cabinet.
The cabinets use hi-density matrix spray-paint technics and the bottom bracket
design which makes mounting quickly and flexibly. HF compression driver and
vented LF for fully professional performance.
The LTO MS1 speaker modeller is designed for using together with MS series
passive speaker cabinet. It has built-in 16 EQ curves which are suitable for
different applications and are convenient for users to select the presets as
need. When the nonprofessionals use it, they also can obtain optimal effects.
It uses external power which can effectively decreases the power noise. Not
only can it be used with the MS series cabinet, but also can be used as a EQ
together with the other sound equipments.
Enjoy your MS passive speaker and make sure to read this Manual carefully
before operation!

2. QUICK START - PASSIVE SPEAKER CABINET
UP
Passive, Full-range, two speakers. This is the simplest set-up. You just need
a mixer and a stereo amplifier. It is good for small club gigs, disco,etc.
Make all initial connections with all the equipment powered off, and ensure that
all the main volume controls are turned down completely.
1). Connect one side of the speaker cable to the Output CHA/CHB or Binding
Post of your stereo power amplifier and the other side to the Input socket
of your MS speaker cabinet.
2) Connect the input terminals of LTO MS1 with the AUX SEND OUT (L&R)
of a mixer (or the similar terminals). Connect its output terminals with the
inputs of a power amplifier. Then select the preset as need.
3). Complete other connections as illustrated.
4). Turn on your mixer and MS1 first, then the stereo power amplifier.
5). Turn up the volume controls of your amplifier to about 70%.
6). Use PFL function to get the proper input level for the mixer, and adjust the
Main Mix Level control to manipulate the output level.
7). After using, turn off your stereo power amplifier first, then the mixer and
the MS1.
