1- Input Connection
Use push-button for fixed installation.
The Positive connection is usually marked with ( + ), or Red push-button. Use it to connect the amplifier output ( + ).
The Negative connection is usually marked with ( - ), or Black push-button. Use it to connect the amplifier output ( - ).
2- Power Selections
With this rotary switch, it is possible to select the power level of MWS40T from 5W minimum to 40W maximum for two
different constant voltages 70V or 100V. In Off position the speaker system is disconnected from the Line. For
MWS40T, the bypass is activated in 6 Ohms position.

Connection Diagram
MWS40T have built in transformer of 70/100V , can connect many speakers to one channel , and only need one
amplifier. The amplifier output terminal "com/-'' stands for negative polar, terminal "70V/100V/+" stands For positive.
The red speaker terminal stands for positive, black stands for negative. Please connect amplifier to speaker right,
incorrect connection may cause damage to amplifier and speaker. Finally set your desired output power, see picture
C to adjust band switch to meet your need, in this case, the total power of all the speakers can't exceed the nominal
power of amplifier. One 320W amplifier channel can drive 8 speakers of 40W, i.e. 40×8=320≦320W). For safety,
the total power of all the speakers should be less than 3/4 nominal power of amplifier. (One 320W amplifier channel
can drive 6 speakers of 40W, i.e. 40×6=240W≦320W).

Step 1: Fasten the bracket(1) on the wall with screws. The wall material must support the weight of the cabinet.
Step 2: Place the body of cabinet in bracket(2) and lock the screws tightly.
Step 3: Use screw (3) lock bracket(1) and bracket(2)﹐and use steel rope (4) to connect two brackets.
INDOOR INSTALLATION DESCRIPTION:
WMS series speakers are designed specially for fixing and using in different circumstances. The property of
speakers may be different due to different circumstances. There is an acoustic surface (wall, floor and ceiling) in a
closed room, so the acoustic indoor will turn complex. When acoustic wave hits the surface, a part of acoustic
energy is reflected, others are absorbed.
Reflection and absorption are depending on the frequencies of acoustic wave and angle of hitting surface. When

furniture when installing. Reverberation is the results of the reflected acoustic wave continue bouncing between the
surfaces.
Installation Description

Every reflection will loss the energy. When the acoustic hit the reflection surface, the room will be filled with random
reflected acoustic wave. The music and address will be complex. It is recommended that install more speakers and
make the volume of speakers lower to reduce the reverberation in high reverberating room.
Speaker coverage range: Direct the center axile of the speaker to the flat surface of receiving area. The speakers
of 90°×90° series can spread the speaker tone to all the directions at the axile of 45°. If you use the speakers in a
large room, you can divide the room to some zones. Then decide the installing location of the speakers .
