2. CONNECTIONS

2.1. Connection description

1 1

Fig.1. Joker (passive) connectors

1- SPEAKON: All models use two Speakon terminals and are duly prepared for a

perfect connection in a parallel system. Terminal Pins +1/-1 must be always used,

disregarding the +2/-2 which are not internally connected.

WARNING: It is strongly recommended to use a two-conductor high quality wire, non-

shielded and two-coloured. We recommend using a minimum section of 4mm2for

each conductor. Avoid long wire distances as they induce to important power and

quality losses

2.2. Configurations

2.2.1. Full Range Stereo configuration

Connect each output of the amplifier LEFT/RIGHT to each cabinet using two

independent wires.

Fig.2. Full range stereo configuration

Master Audio

Joker Series (Passive). Version 1.4 Jan14 5

2.2.2. Full Range Parallel configuration

Connect the amplifier's output to the Speakon’s input of the first cabinet, always

respecting the polarity positive +1, negative -1. Then, make a bridge from the first

cabinet to the second one. This configuration allows us to connect up to four cabinets

to the same amplifier.

Fig.3. Full range parallel configuration

2.2.3. Passive configuration with Subwoofer

There will be times when you will be interested in reinforcing your Joker Systems with

subwoofer units, in passive mode. In this case only one amplifier will be used for the

whole system.

Connect one of the outputs of the amplifier to the subwoofer through a wire. Then,

make a bridge from the slave Speakon connector of the subwoofer to its respective

mid-high top unit, always respecting the correct polarity between both systems. Do

the same with the other channel.

It is also correct, if the installation requires so, to make the connection in the opposite

way, that is, from the amplifier to the satellite and then to the subwoofer.

Fig.4. Passive with subwoofer configuration

Joker Series (Passive). Version 1.4 Jan14 6

2.2.4. Bi-Amplified configuration with Subwoofer

A wire with the maximum available section (4mm2minimum) should link the low

frequencies output channel of the amplifier to one of the subwoofers. Two subwoofers

can be also connected by bridge one to another, as long as the polarity is strictly

respected.

Connect the other output of the amplifier to the Full Range cabinets.

It is also possible to use only one amplifier for the low reinforcement, connecting each

one of the subwoofers to the two outputs of the amplifier and consequently,

connecting the Full Range cabinets to a second amplifier.

Fig.5. Bi-amplified with subwoofer configuration (option 1)

Fig.6. Bi-amplified with subwoofer configuration (option 2)

WARNING!!!!: In order to allow a bridge connection between cabinets, each one of

them has been provided with two Speakon connectors that allow the Input / Output

function indistinctly. Terminal Pins +1/-1 must be always used, disregarding the +2/-2

which are not internally connected.

3. MOUNTING AND PLACEMENT

For a proper installation of the acoustic cabinet systems, it is strongly recommended

to read carefully the following advices.

3.1. Placement

The Full Range cabinets should be located in a high position (between two or three

meters), slightly inclined to the audience. If the loudspeakers are located too low, the

listeners at the end of the room will not hear a good sound quality.

.

Fig.7. Flying placement

It is advisable to locate the subwoofer units on the floor as they can take advantage

of the so-called “floor-effect”, thus increasing the response in the low frequencies.

If possible, place the subwoofers under the same acoustic axis used for the satellites.

If the above option cannot be carried out, then they should be placed in an

intermediate point between the left and right channels.

3.2. Tripod use

The JK26, JK10, JK12 and JK15 models are equipped with a tripod socket for use

with a standard 35mm tripod.

Do not use the tripod on non-flat floors and be careful not to raise the cabinet too high

on the tripod, as it may become unstable.

Fig.8. Full range cabinet with tripod

Joker Series (Passive). Version 1.4 Jan14 8

3.3. Full range cabinet with subwoofer

The JK12W, JK15W, JK18W1 and JK18W2 are equipped with a M20 Plate for a

35mm distance rod. You can use it to place over the subwoofer the models that are

equipped with the tripod socket (JK26, JK10, JK12 and JK15). Be careful not to use

this system on non-flat surfaces as it may become unstable.

Fig.9. Full range cabinet with subwoofer

3.4. Live applications (mobile)

For a mobile application, whether it is an outdoor or indoor installation, the common

location is to place the bass units (one or two per channel) on each side of the stage.

Fig.10. Mobile applications

To obtain a clear and free-distortion reproduction, it is advisable to place the mid-high

units on top of the low units keeping between them an approximate height of two

meters. If such height cannot be achieved nor maintained, it is advisable to use the

classical tripod for each mid-high cabinet and leave the low units on the floor.

Master Audio

Joker Series (Passive). Version 1.4 Jan14 9

WARNING!!! For installations that suffer from acoustic problems and in which it is

necessary to reinforce the response in the low frequencies, it is advisable to group all

the subwoofers together in the same point. By this way, cancellations will be avoided

and a higher acoustic pressure level will be obtained.

3.5. Asymmetrical and rotatable horns

The JK10, JK12 and JK15 models incorporate an asymmetrical dispersion horn which

will optimise coverage either in horizontal or vertical position.

To rotate the horn, unscrewed the frontal grille, and then, unscrewed the four fixing

screws of the horn. Rotate it 90 degrees taking care of the wires. Screw the horn

again and finally place the frontal grille in its right position.

Fig.11. Rotatable horn

Good coverage of audiences often is a conflicting combination of:

*wide coverage for the closest audience (short throw)

*narrow coverage for distant areas (long throw)

The asymmetrical dispersion horn coverage varies from "short throw" to "long throw"

along the vertical axis (keeping a constant vertical directivity). In conclusion,

directivity feature of (50º to 100º(H), 55º(V)) can be seen as if the horn itself had "two"

horizontal directivities (audience coverage), which depend on the distance. For short

distances the horn should be used with its "wide" dispersion (100º). For long

distances the horn should be used with its "narrow" dispersion (50º).

We suggest you to pay attention to the following examples.

3.5.1. Vertical-Positioned Cabinets (Flown and aiming to the audience)

We need wide coverage (100º) for the closest listeners and narrow coverage for the

distant audience.

3.5.2. Horizontal-Positioned Cabinets (Flown and aiming to the audience)

We need wide coverage (100º) for the closest listeners and narrow coverage for the

distant audience.

WARNING: The horns have the "Nearfield" mark printed on the 100º horizontal

coverage side.
