2. GENERAL DESCRIPTION

Speakers are compact two-way speaker systems designed for high efficiency, wide range, and high power input

handling capability. These speaker systems can be installed in a manner ideal for the location and intended

application. The speaker is certiﬁed to the European Standard EN 54 24:2008.

3. FEATURES

• Wide directivity high-frequency horn.

• Supplied bracket permits mounting to a wall.

• Impedance change available by a rotary switch located in rear side.

• Certiﬁed to EN 54-24:2008.

4. IMPEDANCE CHANGE

To change the impedance, Please rotate the rotary switch on the speaker's rear to select the desired input power.

CSB-40T / 40TW

The switch is factory-preset to 250Ω.

CSB-20T / 20TW

The switch is factory-preset to 500Ω.

Never set this switch to the "250Ω" (CSB-20 series), "500Ω" (CSB-40 series)

position when operating the speaker on 100 V line.

Failure to follow this instruction could result in damage to the speaker or ampliﬁer.

5. WIRING AND USING TERMINAL COVER

Notes

• For the speaker cable, use a cable with a diameter of 6mm, which will ﬁt the cable bushing.

• To ensure waterproof capabilities, ﬁrmly mount the terminal cover to the speaker and tighten the bushing on the

cover.

Step 1: Feed the speaker cable through the bushing and terminal cover, then connect the cable to the input

terminal.

Step 2: Attach the terminal cover to the speaker.

Attach the cover while pulling the cable so that it is not entangled inside the terminal cover.

Step 3: Hold the terminal cover tightly to the speaker using the supplied screws.

Step 4: Tighten the bushing.

Note: After tightening the bushing by hand, use a tool to further tighten it another 90º (1/4-turn) or so. Note that

parts can be damaged by over-tightening.

6. INSTALLATION

Note: Commercial audio installation system must conform to local building laws. When install speaker on wall or

ceiling, please consult a building constructer with a license or a professional engineer. The corporation won't be

responsible for the improper installation or damage because of not conforming to installation description.

Installation procedure of CS-3 bracket is very simple and convenient, the appearance is pleasing to the eye.

Step 1: Fasten the CS-3 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 CS - 3 bracket(2) and lock the screws tightly.

Step 3: Use screw (3) lock CS-3 bracket(1) and CS-3 bracket(2). Mand use steel rope (4) to connect two brackets.

INDOOR INSTALLATION DESCRIPTION:

CSB 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, and others are absorbed. Reflection and absorption are depending on the frequencies of

acoustic wave and angle of hitting surface. When operate the cabinet, both man and furniture can absorb the

acoustic energy. Please note the position of man and furniture when installing. Reverberation is the results of the

reflected acoustic wave continue bouncing between the surfaces. 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. (Please see figure 5B)

Speaker coverage range - Direct the center axile of the speaker to the flat surface of receiving area.

The speakers of 90˚x90󱔉series can spread the speaker tone to all the directions at the axile of 45󱔉.

If you use the speakers in large room, you can divide the room to some zones. Then decide the installing location

of the speakers . (Please see figure 6)

7. CONNECTION DESCRIPTION

LEVEL DISTRIBUTION SYSTEM CONNECTION DESCRIPTION:

CSB-20T and CSB-40T 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 3A to adjust the 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 x

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 x 6=240W≦320W).
