Frequently Asked Questions - Uni-Fi 2.0 UB52 ELAC

What amplifier power is recommended for the ELAC UB52?

The UB52 can handle up to 140 Watts peak. We recommend an amplifier delivering between 30 and 140 Watts per channel into 6 Ohms for optimal performance without risk of damage.

How to connect cables to the terminals?

Strip about 1/2 inch of insulation, twist the bare wire, then insert it into the 5-way binding post while observing polarity (red for positive, black for negative). Tighten firmly.

What is the best placement for these speakers?

Place them 1 to 2 feet from walls (rear and side) to avoid excessive bass amplification. For stereo listening, form an equilateral triangle with your listening position.

Do the speakers require a break-in period?

Although they sound good from the start, a 20 to 30 hour break-in at moderate volume allows the suspensions and cones to loosen up, improving smoothness and bass extension.

How to clean the ELAC UB52 speakers?

Use a soft, dry cloth or a dusting brush. Never use chemicals, alcohol, or furniture polish, as they could damage the vinyl finish.

Can I use these speakers near a CRT television?

No, because the UB52 are not magnetically shielded. Placing them near a CRT TV can cause color spots on the screen. Use them with LCD/OLED screens without risk.

What is the warranty for the ELAC UB52 speakers?

ELAC offers a 3-year warranty from the original purchase date for any defects in materials or workmanship. The buyer must contact an authorized dealer and provide proof of purchase.

What to do if a speaker stops working?

Do not open the speaker (risk of electric shock). Contact ELAC customer service at 714 252-8843 or email [e-mail] for repair instructions. Servicing must be done by qualified personnel.

Can the UB52 be used in a home theater system?

Yes, they can serve as front speakers in a 5.1 system. Pair them with the UC52 center and UF52 towers for a cohesive setup, or use them as rear speakers. Place the surround speakers at ear height.

How to install the stabilizing spikes?

Turn the speaker over on a soft surface, attach the stabilizer feet and screw in the spikes. Use the Allen wrench to adjust until the speaker is level (watch out for sharp spikes). On a hard floor, place the provided protection discs.

USER MANUAL Uni-Fi 2.0 UB52 ELAC

• 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!

Before Use

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 14 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.

Outrigger Feet & Spike Installation (UF52 Only)

Using the included feet provide a wider support base for speaker cabinet. The included spikes improve stability on uneven surfaces and thickly carpeted floors. Please, use caution when dealing with spikes as they are sharp.

IMPORTANT! In order to prevent scratching or damage 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.

A. Attach the feet with provided machine screws (see fig.A).

B. Screw in the spikes as shown in FIG.B. The speaker can now be turn back over. Please, be careful when handling the speaker with the spikes installed. If you have hard wood tile floors, please use the provided floor discs (fig.B).

C. Using the supplied allen wrench adjust the height of the spikes until the speaker sits level and all four spikes are touching the floor (fig.C).

D. Once the speaker is level, use the supplied covers to lock the spikes into place (fig.D).

Speaker Placement

Achieve maximum performance and optimal sound quality from your ELAC Uni-Fi 2.0 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 (fig. 1) 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 (fig. 2) 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-CHANNEL STEREO SETUP

Surround Sound Setup

Whether you use the Uni-Fi 2.0 bookshelf or the Uni-Fi 2.0 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.

Center Speaker Setup

The ELAC UC52 center channel is designed to produce dialog sounds and should be positioned above or below (fig. 3) your television. Align it with the center of the television. As much as possible, try to keep the UC52 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.
