Focal Cub User manual

User manual

Thank you for purchasing the Cub active subwoofer

which has been designed to be used in a wide range of

audio system applications, stereo or multichannel.

It is ideally partnered with the matching Sib satellite

loudspeaker for a system that combines high performance

sound with elegance and discretion.

In order to gain the maximum performance from this

product it is essential that you read the following

instructions thoroughly. We advise you to keep this guide so that you can consult it

when needed.

Warning :

The active subwoofer should not be exposed to water or moisture.

Objects filled with water (such as fish tanks or plants pots) should not be placed

on the enclosure

• Placement:

Position Cub close to the front main speakers, ideally in-between them.

Cub was designed to work with a wide range of compact loudspeakers. We strongly

recommend the Focal-JMlab Sib whose performance guarantees a high level of sound

quality in stereo and home cinema configurations.

Placement and connection:

• Connection

Before connecting to the mains supply please check that the voltage selector switch and fuse

value is correctly set to correspond with your supply voltage.

A - Hi-fi configuration:

Connection using the low-level

inputs (“PRE OUT” outputs

from the preamplifier).

Connection using the high-level inputs

(loudspeakers output from the amplifier).

In the case of high-level connection, Cub should be connected to the amplifier using a high

quality pure copper cable of at least 1.5mm. Connect the “+” from the amplifier to the “+”

on the Cub (red) and the “-” from the amplifier to the “-” of the Cub (black).

1 - Plug in the AC power cord

2 - Slide the power switch to the “ON” or “STANDBY” position. The “ON” position is

permanently on: “STANDBY” automatically detects a music signal.

3 - Turn the “CROSSOVER” control three-quarters of the way to the right approximately

120Hz if you use the Focal-JMlab Sib

4 - Adjust the “VOLUME” setting to the desired level.

5 - Select the “PHASE” position that gives the most powerful bass.

Set up

B - Home theater configuration

Connect using the low-level inputs (“LFE” or “Subwoofer out” from the audio video

amplifier).

User manual

• The subwoofer produces no sound at

all. Check - in this order

- Is the mains cable connected?

- Is the wall-socket working?

- Is the subwoofer switched “On”?

- Is the standby selector switch set to

Auto power - ie. “On”?

Is music playing through the rest of

the system?

- Is the volume high enough - at least

12 o’clock?

- Check the indicator light again - the

subwoofer should now be working.

• If nothing still happens ...

- Is the signal reaching the subwoofer’s

amplifier?

- Check the following : are all the

connections made correctly?

See connection.

Check - in this order

- On the subwoofer: Is the amplifier

output connected to the Line In

sockets? Out?

- On the amplifier or A/V processor:

Are the cables to the subwoofer

properly connected to the correct

output sockets? (“Preamplifier Out” or

“Subwoofer”).

•

The indicator light does not always-

light up

- Check the mains fuse - if necessary

replace it with one of the same value.

(NEVER use a fuse of a higher value).

• If there is still no sound

- The output signal from the amplifier

is too small to trigger the automatic

detection on the subwoofer.

Solutions:

1. If the subwoofer output level from

the amplifier or processor is variable,

increase it to the point where it is

high enough to be detected by the

subwoofer’s input.

2. The processor or amplifier does not

allow the subwoofer signal to be

adjusted, but instead has a fixed

output. With certain products

where the output level is too weak

(approx. 250mV), and with certain

subwoofers, it is possible to double

the level of the signal by using a “Y”

connector to input a signal into both

subwoofer inputs - left and right.

User manual

Operational problems

• The subwoofer works but cuts out on

loud peaks

- Too high a level.

Focal-JMlab subwoofers are equipped

with electronic protection that will

cut the amplifier in case of overload

generally caused by too high a

short-term peak level. In this case

check that the balance between the

main speakers and the subwoofer is

not set too high.

Input overload

Overload of the input stages can occur

if the output level from an adjustable

output level amplifier or processor is

too high - particularly in some top-of-

the-range processor/amplifiers. In this

case, reduce the level of the subwoofer

output, and compensate by increasing

the subwoofer volume level.

• The fuse blows repeatedly

Check the fuse value.

Caution: When changing from 230V

to 115V, the fuse value must be

changed. See the inscription on the

amplifier panel.
