2. Positioning the Sub Air in your listening room

Unlike loudspeakers, which have to be at sufficient distance from the walls and corners of the listening room, our

advice is to position the Sub Air subwoofer in a corner.

If the Sub Air is positioned up against a wall not in a corner, or a long way away from the room walls, the very long

wavelengths of the low frequencies reproduced will cause random excitation of resonances in the listening space.

The frequency response will not be linear and the quality of the bass will be seriously affected (lack of depth, "tinny

sound", poorly defined and/or poorly held bass, difficult or impossible overlap crossover with main speakers).

By placing Sub Air in a corner, the room resonance will be excited in a more linear and predictable way. Not only

will perception of the bass be optimal, but this arrangement will make it possible to boost the bass by + 6 dB. If, for

practical reasons, you cannot position the Sub Air in a corner, try different positions in the room until you arrive at

the best possible compromise.

Generally speaking, it is best to take care to position the sub-woofer towards the front of the room.

As the frequency bands in question are omni-directional, the bass is not, in principle, affected by an object or item of

furniture placed between the sub-woofer and the listening position.

Connect to the LFE input

When a multi-channel audio/video amplifier is used, the Sub Air transmitter's single LFE input should be connected

to the "Subwoofer" output on the audio/video amplifier.

User manual

Switching Sub Air on

Automatic power-up and standby.

Sub Air is fitted with an automatic audio signal detection system. If "Auto" mode is selected on the "Power" switch,

the unit powers up the moment it detects an audio signal. In "Power On" mode, the audio signal detector is disabled

and the unit remains permanently powered up.

When, on the other hand, the unit goes without detecting an audio signal, it automatically goes into standby.

If the unit is going to be unused for an extended period of several days or more, it is recommended to put the "Power"

switch to its "Off" position.

Caution: in the event of lightning, disconnect the power lead from the mains supply.

Connect mains power and put the "Power" switch into "On" or "Standby" mode.

The connection status LED should be glowing steadily. This shows that the Sub Air Transmitter and Sub Air are

connected. Installation is now complete and you can go on to adjust your Sub Air's Phase, Low pass control and level.

Please refer to the Settings and Operation section to make the most of these settings.

Note: synchronization procedure

Your Sub Air Transmitter and Sub Air come from the factory already wirelessly connected. If, after powering up, the

connection status LED does not glow steadily, but instead flashes slowly (one flash per second), you will need to carry

out the connection procedure by taking the following steps:

• On Sub Air, hold down the connection button for 4 seconds. The connection status LED will flash

quickly.

• You now have 30 seconds in which to hold the connection button on Sub Air Transmitter down for 4 seconds. The

connection status LED on Sub Air Transmitter will flash quickly.

• Connection is now complete and the connection status LEDs on Sub Air and Sub Air transmitter will

be glowing steadily.

Note: It is only possible to connect one Sub Air to one Sub Air Transmitter at a time and the other way round. Once

the connection has been made you will not have to repeat the procedure.

User manual

Settings and operation

Low pass control

If you are using the LFE input on Sub Air or Sub Air Transmitter, turn the low pass rotary control (LO PASS) to its

LFE position.

If you are using the Left and Right inputs on the Sub Air or Sub Air Transmitter, low pass setting depends on which

satellite speakers you use and their diameter. Here are our recommendations for Focal satellites:

If using Sub Air with satellite speakers other than those shown above, adjust the low pass frequency using the di-

ameters for midrange speakers.

Phase control switch

The phase setting on your Sub Air is heavily dependent on your room interior, listening point and satellites. However,

once you have installed your system we advise you to take the following steps to ensure the best setting:

• Play a piece of music with high bass energy.w

• From you ideal listening position, listen to the music with the switch first in the 0° position and then in the 180°

position.

• Choose the switch setting which gives you the strongest sensation of the bass. This shows that the Sub Air is in

phase with your satellites.

If there is no detectable difference between the two settings, put the phase selector in its 0° position.

Level control

f you have a 5.1 set-up, we advise you to set the Sub Air at ¾ volume and to then adjust the sub-woofer volume with

your Home Cinema amplifier. If you have a 2.1 set-up, the volume setting of your Sub Air is heavily dependent on your

room interior and listening point.

Simply adjust its volume to suit your wishes and taste in listening.
