Is there any evidence the unit has

been subject to a power surge of any

type? (i.e lightening strike etc)

Is there any evidence of burnt

components or smoke has come from

the Loudspeakers?

Loudspeakers have been over-driven?

(i.e listened to at excessively high

volume levels)

Do the Loudspeaker/s fail to power

on?

Section 1

Swap the

Loudspeaker or signal

cables from left to

right.

Do the symptoms stay with the

suspect Loudspeaker?

Identify what part of

the Loudspeaker the

symptoms are coming

from. (See Fig 1)

It is unlikely that the

fault is with the

Loudspeakers.

Do the symptoms come from

the 3K Array, Upper or Lower

bass drivers or the Amplifier

module?

Do the symptoms follow the

Amplifier Module?

Do the symptoms follow the 3K

Array?

Check all other

units, cables etc in

the system.

once suspect part or parts

have been identified.

(Stage 3.2)

Are the Symptoms the exact

same on both Loudspeakers?

Check mains leads and signal

cables are terminated and

connected correctly.

If noise can be heard through

the Loudspeakers, check the

location of mains leads and

signal cables so that they are

situated away from any device

that may generate

interference.

Check all other devices in the

system for faults, i.e Source

products, Pre-amp, Power-

amp or cabling etc.

If possible test the

Loudspeakers in a

totally different

system.

Swap the signal

cables from left to

right.

Do the symptoms remain the

same for each Loudspeaker?

Identify the suspect part from

each Loudspeaker separately.

It may help to do this by

following the flow process in

Section 1.

the fault is with the

Loudspeakers.

APPENDIX 1

Removing & Re-fitting the 3K Array

Before you start

Observe static precautions when carrying out this procedure. Wear footwear that is suitable

for handling heavy equipment. Take care not to cause damage to the speaker cabinet and

amplifier module.

Ensure the product is disconnected from the mains and input cables have been removed.

Page 7 of 29

1.

Remove the 7 securing bolts around the

3K array.

2.

Taking care not to damage any of the

speaker grilles, carefully pull the 3K array

to disconnect it from the rear connector.

3.

Place the 3K array in a safe place to avoid

damage.

REMOVING THE 3K ARRAY

Page 8 of 29

RE-FITTING THE 3K

ARRAY

1.

Carefully locate the 3K Array in position

ensuring the rear connector locates in

position when fitted.

2.

Fit the top mounting bolt first to hold the 3K

Array in position.

Gently move the 3K Array from side to side

to ensure the gap between the 3K Array

chassis and the loudspeaker cabinet is

evenly spaced.

3.

Fit the remaining 6 screws to secure the 3K

Array in position.

APPENDIX 2

Removing & Re-fitting Amplifier Module

Before you start

Observe static precautions when carrying out this procedure. Wear footwear that is suitable

for handling heavy equipment. Take care not to cause damage to the speaker cabinet and

amplifier module. It is advisable that the following procedure is carried out by 2 people.

Ensure there is a soft clean surface that can be used to place the amplifier module on without

risk of damage to the heat-sink.

Ensure the product is disconnected from the mains and input cables have been removed.

Page 10 of 29

1.

Remove and retain the top 6 bolts (as

shown) that secure the module in position.

Do not remove the lower bolts!

2.

Remove the 2 bolts located at the bottom

of the module.

3.

Carefully lean the amp module back, until it

is being supported by the strap.

Disconnect all the cables between the amp

module and speaker (8 cables in total).

Note: Some of these cables are short.

Failure to remove all 8 may result in

damage to the cables and/or the

connectors.

REMOVING THE AMPLIFIER MODULE

Page 11 of 29

4.

Supporting the amplifier module against

your shoulder, locate the securing point for

the top of the strap within the upper rear of

the cabinet.

If the speaker you are working on has one,

remove and retain the nut and washer from

the securing bolt. Other speakers have an

insert within the cabinet.

5.

Ensure the module is being supported

before moving the module towards the

cabinet slightly and then removing the

support strap bolt from the cabinet.

Remove and retain the bolt and washer

from the strap.

6.

Carefully lift the module clear of the rear of

the cabinet and place on a soft protective

surface to stop the module being marked

or scratched.

One of the original packing end caps would

be ideal.

Information

1.

When refitting the amplifier module, be

careful not to damage the fan or its

bracket. The suspended bracket is to be

located in the space between the fan and

the back of the module.

2.

Carefully lift the module and guide the

base of the module into position.

Be careful not to trap any of the cables

underneath the module.

Once in place support the module ready to

refit the strap.

FITTING THE MODULE TO THE CABINET

3.

Locate the end of the support strap, and

make sure that it is not twisted. Refit the

washer and bolt.

Page 13 of 29

5.

The support strap will now take the weight

of the module. You should check that the

strap is straight.

4.

Refit the bolt and strap to the cabinet, and

if applicable, the washer and nut to secure

it in place.

CONNECTING THE SPEAKER TO THE MODULE

PASSIVE ONLY

1.

Reconnect the GREEN banded servo

cable to the module where it is marked

SERVO CABLE (GREEN) towards the

bottom of the module.

The servo cable has grey insulation and is

terminated with a 3 way connector.

If this cable is not fitted, the audio

performance will be reduced.

2.

Reconnect the GREEN banded Red and

Black speaker cable to the module where it

is marked LOWER 8”BASS (GREEN).

The speaker cables have either 2 or 4

cables terminated with a 4 way connector.

Ensure the speaker connectors are

making all connections.

3.

Reconnect the LED cable to the connector

at the top of the upper 8” amplifier board.

The LED must be fitted to the connector

nearest the centre of the amplifier module

otherwise it will not function.

The LED cable has 2 wires, (one red and

one black) terminated with a 2 way

connector.

Page 20 of 29

1.

Taking care not to trap any cables, slowly lift

the module towards the cabinet.

Slightly lift the lower suspended mounting

brackets to clear the small cover plate on the

amplifier module.

2.

Using a 5mm hex key fit the washer and bolt to

each side of the lower module mounting holes.

Given that the brackets are suspended, it is

sometimes necessary to re-align them with the

holes.

Do not fully tighten the bolts at this stage.

Note: It is advisable to use a long shaft hex

key to clear the fins on the module and prevent

damage.
