Frequently Asked Questions - BS 312.2 ELAC

How should I position the BS 312.2 speakers for optimal sound?

Place the speakers on sturdy stands at ear level, angled slightly towards the listening position. Keep them at least 30 cm from the rear wall and away from corners to avoid bass boom. Experiment with toe-in for best imaging.

What amplifier power is recommended for the BS 312.2?

ELAC recommends an amplifier with 30 to 120 watts per channel into 4 ohms. Ensure your amplifier is stable at 4 ohms to handle the speaker's impedance.

Can I bi-wire or bi-amp the BS 312.2?

Yes, the binding posts are gold-plated and allow bi-wiring or bi-amping by removing the jumper bars. Consult your amplifier manual for proper bi-amping setup.

Is there a break-in period for these speakers?

Yes, speakers typically benefit from a break-in period of 20-50 hours at moderate volume. During this time, the driver suspensions loosen and sound may become smoother.

How do I clean the speaker cabinet and grille?

Wipe the cabinet with a soft, dry or slightly damp cloth. For the magnetic grille, gently dust it with a soft brush. Do not use any cleaning agents or abrasives.

Can I wall-mount the BS 312.2?

The BS 312.2 is designed for bookshelf or stand placement and does not have built-in wall-mounting brackets. Use aftermarket sturdy wall mounts rated for 10 kg if necessary.

What is the frequency response of the BS 312.2?

The frequency response is 42 Hz to 50 kHz, providing deep bass and extended high frequencies thanks to the JET tweeter.

How can I reduce excessive bass in a small room?

Use the included foam port plugs to partially seal the bass reflex port, reducing low-frequency output. Alternatively, move speakers farther from walls or use room correction.

What is the sensitivity of the BS 312.2?

Sensitivity is 87 dB (2.83 V/1 m). This is moderate; a powerful amplifier is recommended for high volume levels in large rooms.

Are the speakers shielded to prevent interference with TVs?

No, the speakers are not magnetically shielded. Keep them at least 30 cm away from CRT TVs or other sensitive electronics to avoid distortion.

• Please read and follow these safety instructions.
• Keep them safe for future reference.
• Observe all warnings on the speaker and in the manual. Please check the speaker for damage before use. The speaker must be in perfect working condition. Damaged parts may lead to personal injury.

2. Use only as directed

• Connect the speaker(s) according to the instructions in the manual.
• Many ELAC speakers are equipped with spikes and/or anti-slip feet.

They are explicitly provided for levelling the speaker. For levelling on an uneven floor, unscrew the spikes or anti-slip feet by 2-3 turns of thread. The speaker should always be in perfect vertical alignment: the stability of the speaker must not be compromised by using spikes or anti-slip feet as the speaker may tip-over.

3. Location

• Install the speakers on a level surface only

• When choosing the location of these speakers do not place them in locations that are:

• In direct sunlight

• Very humid
• Prone to vibrations
• Exceptionally hot or cold
• Near CRT Televisions (the speakers are not magnetically shielded and may cause color issues with a CRT based TV)
• Close to magnetic cards (Since the speakers are not magnetically shielded placing magnetic cards such as credit cards or commuter cards may cause them to fail).

WARNING! Please ensure the product is perfectly stable to avoid injury from tip-over. Please note, that stability can be increased by using spikes on carpeted surfaces. However, the mounting of spikes must be carried out carefully due to their very sharp ends which may cause injuries. The stability on slippery floors can be increased by using Velcro fastening tape or double-sided adhesive tape. Do not install the speaker near any heat sources such as radiators, heating valves, stoves, or other apparatus (including amplifiers) that produce heat, or in areas where there is a risk of explosion.

• Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.
• Do not install the speaker in a closed rack or in a closed cupboard.
• Do not put burning candles on or near the speaker.
• Do not install the speaker near transformers because electromagnetic stray fields can cause hum noise on woofers.

In combination with certain materials / lacquers / material surfaces, anti-slip feet or spike washers may cause colored imprints on the surfaces.

4. Overload

Extreme overload of the device due to very high volume may cause damage to individual components. Because of the possible danger, you should never leave loudspeakers under extreme overload conditions unattended.

5. Service

DANGER! Do not open the cabinet because the components and conductors may carry current! Servicing to be carried out by qualified service personnel only.

Servicing is required when the loudspeaker has been damaged in any way, such as damage to the power supply cord or the plug, or when liquid has been spilled or objects have fallen onto the loudspeaker, the speaker has been exposed to rain or moisture, does not operate normally, or has been dropped. To reduce the risk of electric shock, do not open the loudspeaker. Servicing should be carried out by qualified service personnel only.

6. Cleaning

NOTE: Clean only with soft, smooth cloth or with dust brush. Do not use scouring agents, alcohol, benzene, furniture polish or other agents for cleaning! Modern furniture is often coated with multiple varnishes and plastics which can be treated with chemical agents. Some of these agents contain substances which degrade or soften the rubber feet. Therefore we advise that you place an anti-slip mat underneath the loudspeaker(s).

7. Volume

CAUTION! Continuous high volume may cause severe damage to your hearing. Please listen responsibly.

8. Disposal

The packaging is made from recyclable materials. Dispose of this in an environmentally friendly manner. At end of life do not dispose of the speaker(s) with standard household waste. The speaker must be recycled in accordance with local legislation. Ask your local government for further information on recycling as the device contains valuable raw materials. Disable the speaker(s) before disposal.

PHILOSOPHY

Thank you for purchasing this ELAC product.

Since the time we started (1926), ELAC has always striven to achieve the very best.

Your new ELAC speakers are built to the highest standards using high-quality components that are carefully constructed to deliver the best-in-class sound quality. They are developed by a passionate group of individuals whose soul purpose is to bring a new dimension of sound quality into your home. Enjoy!

Avoid damage to the speakers and other components:

- Carefully unbox the speakers carefully to avoid physically damaging your speakers.

- Use appropriate gauge wires (minimum of 12 gauge wire for runs up to 25 feet).

- Make sure wire polarity is connected correctly. Most speaker cables are coded for ease of use. Make sure positive (red) connection on the amplifier terminal is connected to the positive (red) on your speakers. Follow the same instructions for the negative side. Strip off approximately 1/2" of the insulation from the ends of the speaker cable, twist the bare strands and insert into the binding post.

- Ensure your equipment is turned off before connecting speakers.

- Check to ensure positive and negative wires are not touching each other once they're connected to the speaker terminals.

Installing and Removing the Magnetically Attached Grills

The grills of your ELAC speakers are designed to be removable if desired. To remove it, hold the top or bottom edges of the grill and pull gently. To replace the grill, place the grill in the normal position on the cabinet and the magnets will hold the grill in place.

IMPORTANT!

ELAC Floorstanding Speakers Safety Clip

Some ELAC Floorstanding speakers include a safety clip pre-installed on the back of the cabinet for securing to a wall to prevent tip-over. Use support hooks (not included) screwed into a wall and pass appropriate size cord (not included) around the hook and through the safety clip. Test to ensure mounted hooks and cord will prevent tipping of the speaker.

Support Hooks and Cords (not included)

Wal

CAUTION:

The safety clip is not a mounting fixture and the speaker should not be hung on the wall using the clip. ELAC does not claim responsibility for damage resulting from improper assembly, installation, insufficient strength of the installation materials, misuse or natural disasters.

OUTRIGGER PLATE & SPIKE INSTALLATION

Using the included outrigger plate provides a wider support base for the speaker cabinet. The included spikes improve stability on uneven surfaces and thickly carpeted floors.

Please use caution when dealing with the spikes as they are sharp.

IMPORTANT: When using these spikes on hard surfaces such as wood or tile floors be sure to use the provided floor discs to protect your floor from damage.

IMPORTANT: In order to prevent scratching or damage to the cabinet, turn the speaker upside down onto a soft surface while you attach the outrigger feet and spikes. We highly recommend a second person help with this process.
Attach the outrigger plates with the provided machine screws.
Screw in the spikes as shown in the picture to the right. The speaker can now be turn back over. Please be careful when handling the speaker with the spikes installed. If you have hard wood or tile floors please use the provided floor discs.
Using the supplied allen wrench ad-just the height of the spikes until the speaker sits level and all four spikes are touching the floor.
Once the speaker is level, use the supplied covers to lock the spikes into place.

input midrange/treble

jumper

input woofer

Some of our speakers allow separate operation of the treble/midrange and the woofer by means of two amplifiers (Bi Amping) or by means of separate connecting cables (Bi Wiring). For this purpose, the speakers are provided with double terminals. The two pairs of connecting jacks that are provided with jumpers were designed for standard operation (with one amplifier). For Bi Wiring/Bi Amping, the jumpers must be removed. The passive crossover networks of the individual drivers remain in operation. This way, the use of special filter crossover networks is not required.

One pair of connecting jacks is used for the connection to the network of the midrange/tweeter.

The other pair is used for the connection to the network of the woofer.

Due to separate wiring (Bi Wiring), a decoupling of the two legs is obtained.

This reduces cross-talking between the midrange/tweeter leg and the woofer leg.

There are different types of connecting cables that can be used. For example, low-inductance cables are suitable for the treble area and particularly large cables are suitable for the woofer area.

If both legs are operated through separate output stages, it is possible to choose amplifiers that allow the transmis-sion of high, midrange or low frequencies. With separate volume controls for both legs, it will be easier to provide a sound balance that offers perfect adaption to the living room environment (room acoustics).

Please note, that different models of output stages may not provide the same volume when fed by one source through a y adapter. The reason for this lies in different amplification factors that occur between the input and the output levels.

To ensure, that the sound balance will not be defined at random, the amplifiers provide level controls that enable perfect adjustment of the desired sound balance.

It would be advantageous to choose a high-quality amplifier for one of the two stereo output stages. Its volume control can be used to adjust the desired sound balance. The other output stage would be a puristic element that does not offer any adjustment options.

It is important to mention, that there must be prestages for adjusting the volume and programmes. If the prestige provides only one output, a standard cable for the Y adapter can be used.

SPEAKER PLACEMENT

Achieve maximum performance and optimal sound quality from your ELAC speakers with proper speaker placement and set-up. While not all rooms are the same, use the following guidelines to configure the speakers for your particular room. There are no “exact” rules or boundaries in setting up your speakers but the following suggestions will help optimize your desired results. Remember the best sound set-up is what sounds best for you so don’t be afraid to experiment and make adjustments to the placement and directivity of the speakers.

Place the speakers approximately one to two feet away from boundaries such as wall(s) and especially corners. Close proximity to a side or rear wall will enhance bass performance (output), but being too close (particularly to a corner) may result in bass that is unnatural. If a corner location is unavoidable, try to position the loudspeaker so that the distance to the rear wall is not equal to the distance to the side wall.

STEREO-SETUP

For the best results and the most realistic stereo image and lifelike sound, place the speakers so that an equilateral triangle is created between the speakers and your favorite listening position. This set up creates the optimum imaging performance.
If you find that your front left and right speakers are too far apart, angle (toe in) them towards the listening position to gain a more focused central image.

2-Canal-Stereo-Setup

Whether you use the Adante bookshelf or the Adante floorstanding speakers for a 5.1-channel surround set-up, avoid placing the surround speakers forward of your listening position. The surround speakers should be spread apart wider than the front speakers. In addition, elevate the speakers to the same height or slightly higher as the front speakers for the most enveloping sound field. Like the front speakers, you may need to experiment with the positioning by pointing the rear surround speakers towards the listening area.

5.1 Canal-Surround-Setup

The ELAC center channel is designed to produce dialog sounds and should be positioned above or below your television. Align it with the center of the television. As much as possible, try to keep the speaker close to the same level (height) as your front speakers for a more even sound stage. Keeping the same height for the center channel can be very challenging so it might be necessary to tilt the center speaker up (if too low) or down (if too high), to aim it towards the listening area.
