IMPORTANT SAFETY NOTICE

Please read through the instruction manual carefully before starting to use the device. This manual contains important information concerning operation and safety aspects. It is imperative you observe all of the information. Keep the manual in a safe location.

• Never subject the subwoofer to dripping or splashing water. Do not place any flower vases or other filled recipients on top of the subwoofer.
• The distance between the active subwoofer enclosure and the walls of the room or other objects (e.g. furniture, shelf units) may not be less than 5 cm on any side.

The aluminium plate and cooling fins of the amplifier at the rear of the active subwoofer serve to cool the built-in amplifier; for this reason, they must also be at least 5 cm away from all objects and must not be covered (e.g. by a curtain).

The bass reflex opening(s) on the active subwoofer must not be covered (e. g. by curtains, etc.) in order to guarantee adequate ventilation of the amplifier.

• The subwoofer should not be positioned near heat sources (heaters, ovens, radiant heaters, naked flames, etc.).
• Only operate the subwoofer at an ambient/room temperature from 10^ C to 40^ C. The active subwoofer may not be used in very humid rooms.
• Please do not place any items with naked flames (e.g. candles) on the active subwoofer.
• Please do not touch or connect the mains cable when your hands are damp.
• Keep the mains cable away from heaters.
• The device should not continue to be operated if there is visible damage to the mains cable. A damaged cable should not be repaired, but must be replaced.

• Never place heavy items on the mains cable.

• The mains cable should always be freely accessible.

• If the device is not going to be used for a prolonged period (e.g. when on holiday), it should be disconnected from the mains by removing the plug. The device should also be disconnected from the mains in the event of a thunderstorm. Doing this will prevent damage caused by lightning and overvoltage.
• Do not use any cleaning agents or chemical solvents when cleaning, as these could damage the surface of the device.
• Repairs must always be conducted by qualified specialists, as you might otherwise be exposed to dangerous high voltage levels or other hazards.

POSITIONING

The frequency range reproduced by the subwoofer cannot be pinpointed by the human ear. That's why positioning generally doesn't present any problems. However, it is normally beneficial to place the unit close to the front speakers. The Ambient Sub 88 F is a compact subwoofer that can be positioned either horizontally or vertically or be mounted on the wall.

Horizontal setup: The flat shape means that the subwoofer can also easily be installed in confined spaces, e.g. under an item of furniture (sideboard, couch). Care should be taken to ensure that the reflex tubes are not obstructed and are not covered by a wall or any other object. The status display (3b) should also remain visible.

Vertical setup: When installing vertically, the side in which the speaker and amplifier are fitted should face a wall. The rubber feet then act as spacers. The rubber pads provided should be glued to the bottom (see fig. 4).

Wall mounting (e.g. behind a at-screen TV): To fix the unit securely to the wall, the mounting brackets provided are screwed to the bottom using the four screws supplied. The subwoofer with the brackets is then mounted onto suitable screws (not included), which have to be fitted securely to the wall horizontally at a distance of 346 mm apart (see fig. 5). Please only use screws that are suitable for the wall material concerned and which will support the weight of the subwoofer!

Note: The subwoofer should not be mounted higher than 30 cm above the oor or another stable surface (sideboard etc.). The subwoofer should not be mounted in a place where people pass by frequently (e.g. near a door).

THE SUBWOOFER'S OPERATING ELEMENTS (FIG. 1)

Mains connection (6)

The subwoofer is equipped with an integrated amplifier and needs to be connected to a mains outlet by means of the supplied mains cable. The subwoofer can be operated on mains voltages of 100 v - 240 v (50-60 Hz).

Power-Switch (5), Power-LED (3)

The subwoofer is switched off in position „Off“ and on in position „On“. The power LED is initially red (standby). When the subwoofer receives a signal from the receiver, it automatically switches from standby to normal, the LED then turns green. When signals to the subwoofer stop, it will automatically switch to standby after around 20 minutes. The power switch should be switched to „Off“ if the machine is not used for longer periods of time.

Line inputs (4)

For connecting to level outputs on a receiver/amplifier (stereo mode), see Fig. 2.

For connecting to an AV receiver with low-level subwoofer output, see Fig. 3.

To connect the cinch NF cable (not included), please use the cinch L adapter provided.

Level control (1)

This control is used to set the bass volume according to your preferences. Proceed as follows::

1. Set the bass control of your amplifier into its centre (linear) position.
2. Important: Set the level control to its left stop (lowest volume).
3. Now, play back some music and set the volume control of the amplifier to the desired level.
4. Set the subwoofer level control to the desired bass level.

Cross-over frequency control (2)

Used to set the upper limit of the subwoofer operating range. The cross-over frequency should be set to 100 to 150 Hz when the system is used in combination with shelf loudspeakers or 50 to 100 Hz when used with stand loudspeakers.

MAINTENANCE

The surface is best cleaned with a mild household cleaner. On no account use furniture polish or similar products.
