Loewe Audiodesign Subwoofer 525 Manual

Introduction

Neither technology nor design is an end in itself, but both are intended to provide our customers with the best possible audio and visual experience.
Our design is not influenced by short-term, fashionable trends. You havem after all, purchased a high-quality piece of equipment which you do not want to tire of tomorrow or the day after.
The Loewe subwoofer is fine-tuned for use with Loewe TV sets (froms chassis L27xx/SL1xx/SL2xx) as well as with Loewe loudspeaker systems. Loewe TV sets (from chassis L27xx/SL1xx/SL2xx) with an integrated digital multi-channel audio decoder transfer the audio signals to the subwoofer via an Audiolink cable or via a Digital Audiolink cable. The Loewe subwoofer then switches itself on and off with the Loewe TV set. The audio settings can be selected conveniently using the menus of the Loewe TV set.
You can also use the Loewe subwoofer along with an external audio source.
However, you then lose the Loewe system advantages (e.g. automatic on/off switching). In this case, see your decoder (e.g. AV receiver) for operating instructions.

Safety

For your safety
For your safety and to avoid unnecessary damage to your TV set, please read and observe the following safety instructions:

• The unit is intended exclusively for the playback of audio signals.
• Always switch off the unit before connecting or disconnecting other devices or speakers.
• Do not allow the unit to run when it is unattended. If the unit is not to be used for an extended period, switch off the mains switch or unplug the mains plug.

Protect the unit from:

• Damp, moisture, steam, dripping water or sprayed water
• Knocks and mechanical stress
• Magnetic and Electrical fields
• Higher electrical power than specified
• Cold, heat, direct sunlight and high temperature fluctuations
• Dust
• Covers that obstruct air circulation
• Interventions inside the unit

Do not place objects containing liquids on top of the unit.
Candles and other open flames must be kept away from the unit at all times to prevent the spread of fire.

This unit has been built exclusively for private use in domestic environments. Warranty services cover this intended use of the unit.

TO PREVENT ELECTRICAL SHOCK, DO NOT OPEN THE UNIT. THERE ARE NO PARTS INSIDE THE UNIT CAN BE REPAIRED BY THE USER. REPAIRS SHOULD ONLY BE CARRIED OUT BY A LOEWE DEALER

If you have moved the unit out of the cold into a warm environment, leave it switched off for about an hour to avoid condensation forming. Do not switch the unit on until it has reached room temperature. This prevents serious damage to the components.

Care / Setup

Cleaning

Only clean the unit with a damp, soft and clean cloth (without using any kind of harsh cleaning agent).

Setting up the device

Basic information

• Place the unit on a stable, even surface.
• Do not set up the unit near strong heat sources or in direct sunlight.
• When installing in a cabinet or closed shelf, leave about 10 cm free around the unit to allow the air to circulate freely, thereby avoiding a build-up of heat and sound pressure.
• Disconnect the mains plug during thunderstorms. Surge voltages caused by lightning strikes can damage the unit through the antenna system and the mains.
• If the unit is not to be used for an extended period, the plug should also be disconnected from the mains.
• The mains plug must be easily accessible so that the unit can be disconnected from the mains at any time.
• 
  Lay the speaker and power cables in such a way that they cannot be dam-aged. The power cable may not be kinked or laid over sharp edges, stood on or exposed to chemicals; the latter also applies to the system as a whole. A power cable with damaged insulation can cause electric shocks and poses a fire risk. As such, it must be changed before the unit is used again.
• When unplugging the unit from the mains, pull the plug housing and not the cable. The cables in the mains plug could otherwise be damaged and could cause a short-circuit when being plugged in again.
• The speakers generate stray magnetic fields which act in the vicinity of the housing. We recommend a minimum distance of > 0.5 m from magnetically sensitive equipment such as CRT TV sets, magnetic data media, etc.

Subwoofer
You can position the subwoofer anywhere on the floor,
We recommend the front area of the room in a way that the basses can freely flow to the sides and downwards.

Never obstruct the air vents on the back of the subwoofer. Make sure it is far enough away (> 10cm) from the floor or wall.

Connection

Cabling for Loewe TV set (SL2xx) - Loewe subwoofer - loudspeaker

• The TV set must be equipped with a Digital Audiolink.

You can either connect the subwoofer via a network cable (Cat. 5e or higher) and the Converter Digital Audiolink / Audiolink (included with the Loewe Subwoofer 525, order no. 69211T/U/W30) or you can connect it wirelessly to a compatible audio source via the Module Wireless AudioLink which can be optionally retrofitted.
If you wish to connect the subwoofer using the network cable, connect the Converter Digital Audiolink / Audiolink to the 25-pin Audiolink socket of the subwoofer. Use the network cable to connect the Digital Audiolink of the TV set to the socket of the Converter Digital Audiolink / Audiolink.
Connect the speaker cable to the speaker according to the appropriate installation instructions. One of the two wires of the speaker cables is usual marked black. Connect this black marked cable to the black screw terminal on the subwoofer (connection diagram, see figure below) and the black terminal on the speaker. Turn the screw connection of the respective terminal on the subwoofer anticlockwise about 5 turns. Feed the wire end into the screw terminal (top right-hand side) and close the screw terminal by turning it clockwise. Connect the unmarked wires to the red terminals.
Use the mains cable supplied to connect the 220-240 V socket of the subwoofer to a 220-240V 50/60 Hz socket.

Cabling for Loewe TV set (L27xx/SL1xx) - Loewe subwoofer - loudspeaker

• The TV set must be equipped with an integrated digital multi-channel audio decoder. If this has not been done at the factory, please consult your dealer and ask them for the suitable Loewe upgrade kit.

You can connect the subwoofer either via an optional Audiolink cable or via the optional upgrade module Wireless AudioLink wirelessly with a compatible audio source.
If you connect the subwoofer via the Audiolink cable, install it with the 25-pole connector at the Loewe TV set and at the subwoofer (socket Audiolink ).
Connect the speaker cable to the speaker according to the appropriate installation instructions. One of the two wires of the speaker cables is usual marked black. Connect this black marked cable to the black screw terminal on the subwoofer (connection diagram, see figure below) and the black terminal on the speaker. Turn the screw connection of the respective terminal on the subwoofer anticlockwise about 5 turns. Feed the wire end into the screw terminal (top right-hand side) and close the screw terminal by turning it clockwise. Connect the unmarked wires to the red terminals.
Use the mains cable supplied to connect the 220-240 V socket of the subwoofer to a 220-240V 50/60 Hz socket.

Start-up and settings

Before beginning with the start-up and settings, make sure that all the cables are connected correctly.

Switching the subwoofer on/off

Use the mains switch to switch the subwoofer to the ON position.

Mode with Loewe TV sets

If the subwoofer is connected as described on side 12 or 13 and the Auto

Mode switch is in the OFF position, you no longer need to switch the subwoofer on and off separately. After switching on the subwoofer for the first time it is switched on and off automatically with the Loewe TV set.

Automatic mode with other audio sources

If the Auto Mode switch is in the ON position and audio signals are present at the cinch sockets Line IN Front Left/Center/Front Right, then the subwoofer switches itself on automatically. If no audio signals are present at these sockets for a duration of 10 minutes, then the subwoofer switches itself off automatically.

• The subwoofer can switch itself on automatically if any interfering signals are present on the audio cables. In this case, switch the unit off at the mains .
• The subwoofer can switch itself off automatically during long, very quiet passages in the playback. You will need to turn up the volume.

Settings on the Loewe TV set

Make the necessary settings to your subwoofer as described in your Loewe TV set's operating instructions in the "Operating additional devices" / "External devices" chapters.

Setting the equalizer

Using the Equalizer knob you can set the lowest frequency ranges (20 Hz - 50 Hz) for bass reproduction to be raised or lowered.

• If the subwoofer is near the corner of the room, turn the Equalizer knob more in the -3 dB direction.
• If the subwoofer is near a wall, then turn the Equalizer knob more to the middle position.
• If the subwoofer is freely positioned in the room, turn the Equalizer knob more in the +3 dB direction.

Bass intensity

Using the Bass Intensity controller you can set the basic bass volume to suit you.

Setting the crossover frequency

You can use the Crossover Frequency knob to set the crossover frequency for bass reproduction between 50 Hz and 250 Hz depending on which speakers you have connected.
As described on side 12 or 13, for Loewe audio systems the knob should be set to 250 Hz because the crossover frequency is set to this in the Loewe audio sources (TV set).

Wireless

Set the wireless switch to the OFF position once you have attached the subwoofer to an audio source via a cable, otherwise you will not hear any sound.
Move the Wireless switch to the ON position if you wish to connect the subwoofer wirelessly to a compatible audio source.
Activate Coupling mode, as described in the instruction manual of the relevant audio source. Use the Wireless Pairing button on the subwoofer using a sharp object. A message appears on the display of the audio source if the registration was successful. If the registration was not successful, please try again and reduce the distance of the subwoofer to the audio source.

Cover on the subwoofer

After you have made the settings described in "Start-up and settings", mount the cover on the rear of the subwoofer.
