Installation

We recommend that your Akubarik loudspeakers are unpacked, installed and adjusted by an authorised Linn retailer. To get the best from your Akubarik loudspeakers, it is important that they are positioned and levelled correctly.

Please note, in order to achieve the very best from your Akubarik, some adjustment may be required after positioning, levelling and connecting. See the Fine adjustment section.

Unpacking

IMPORTANT: The Akubariks are heavy; take great care when moving them.
When unpacking, lifting or moving them, we recommend using two people to avoid personal injury.

• Do not lift your Akubarik using the amplifier module, this will cause damage to your loudspeaker.

• Do not lay the loudspeakers on their front face or the amplifier on the rear as this will damage the loudspeaker.

• We recommend that you retain the packaging in case you need to transport your loudspeaker(s) at a later date.

• Loudspeakers are packed individually with a separate package containing both speaker stands.

• Take care when unpacking to avoid damage to the cabinets.

Move the (boxed) loudspeaker to an uncluttered, flat area adjacent to its eventual position (this will avoid any excessive moving and carrying of unpacked loudspeakers).

Stand the loudspeaker box on its base.

Remove the plastic clips holding the box together (four from the base and one from the sleeve).

Remove the cardboard sleeve by lifting it straight up until it clears the top of the cabinet

Leaving the top end cap on (to protect the loudspeaker) turn the Akubarik upside down.

Remove the bottom end caps to allow the stand to be fitted (see below).

Once the stand has been fitted, carefully rotate speaker onto the stand. Lift the loudspeaker out of the top end-cap and remove its protective bag.

Leave the packaging between the amplifier module and the cabinet and the 3-K Array cover in place until the loudspeakers have been moved to their final position.

Once you have positioned the loudspeakers, remove the two packaging pieces between the amplifier and the cabinet and VERY CAREFULLY snip the plastic tie holding the 3-K Array cover in place and remove it.

Fitting the Stand

On a clean, level surface that will not damage the loudspeaker; carefully stand the speaker upside-down without laying it on its front or rear face.

Remove the five bolts holding the transit plinth in place using a 13mm socket spanner.

Remove the transit plinth and retain with the packaging in case you need to transport your loudspeaker(s) in the future.

Position the speaker stand above the speaker as shown above and attach using the 5 bolts removed earlier.

IMPORTANT: Take care not to over tighten the bolts.

Positioning

As with any stereo loudspeaker there are some fundamental principles which should be observed to get the best sound from your loudspeakers.

• The loudspeakers should be place at an equal distance from the wall behind the loudspeakers.
• The speakers should be a similar (not the same) distance from the walls to the outside of each loudspeaker.
• Any toe-in applied should be the same for each loudspeaker.
• The loudspeakers should be level with all four spikes in contact with the floor. Use Linn Skeets for hard floors.

As the Akubarik loudspeaker has a ported bass system the low frequency performance will be better if the loudspeakers are pulled out from the wall, 20-30cm is a good starting point, but adjustment will be required to get the best results. Additional benefit will be heard in the upper midrange and high frequencies by placing the loudspeakers away from the rear wall.

The Linn 3K Array used in the Akubarik loudspeaker offers exceptional dispersion characteristics. This means that there should be little or no need to toe-in your loudspeakers.

For further assistance, try our customer support pages or the Linn Forum.

Levelling

Screw the spikes into the corners of the stand.
Fit the lock nuts but do not tighten at this stage.

Very carefully (do not scratch the cabinet), use a spirit level to check if it is sitting level. If it is, gently rock the loudspeaker from front to back, side to side and diagonally to check for any movement. If none is present and the loudspeaker is sitting level, no adjustment to the spikes is necessary.

If the loudspeaker is not level, or moves when you rock it, loosen the appropriate lock nuts using the tool provided and use a screwdriver to turn the spikes to adjust their height. Adjust the spikes to level the speaker, using a spirit level placed on the stand.

Press down firmly on the top of the loudspeaker to ensure it is in close contact with your flooring.

Use the spirit level as before and continue to adjust the spikes as required.

Once the speaker is level and does not rock, use the screwdriver to hold the spike in place and fit and tighten the lock nuts with the spanner provided.

Note: To protect wooden or tiled floors, the spikes can be placed on Linn Skeets which are available from your Linn retailer.

Operation

Image:Akubarik_Exakt_OFF.jpg

General

If the Exakt DSM is in Standby, the Akubarik speaker is totally shutdown. No LED's or indicators are shown

When the Exakt DSM is brought out of Standby it will send trigger voltage and wake the speaker up. The LED's beside the Mains socket/Exakt link sockets will tell you the status. After approx 6seconds the Blue LED on the top of the speaker will illuminate stating "its ready to party!"

Signal sensing

When an input signal is detected, the Chakra amplifier is enabled and the blue LED lights (red LED goes off). In the absence of an audio signal, the amplifier reverts to a sleep mode after approximately 20 minutes.

Protection

Operation

If an amplifier channel overheats or detects an overload condition, the power supply for that channel will shut down in order to protect the amplifier and the loudspeaker drive unit(s) to which it is connected.

Duration

Once the condition that caused the amplifier to activate its protection has passed, the amplifier will automatically resume normal operation. How long the channels remain in protection will depend on the cause. If the protection operates for more than a few seconds, it could indicate overheating which may take some minutes of cooling to rectify.
