2 This booklet contains information on the Elan series loudspeaker range. UNPACKING While unpacking, please take care to locate the internal cartons containing the cloth-covered grilles and retain them in a safe place. It is advisable to retain all the packaging materials, in case your speakers ever need to be transported. CABLE TERMINATIONS A set of 4mm plugs is supplied which will allow you to terminate your loudspeaker cables. These plugs have been selected to provide the best possible electrical connection. To terminate your speaker cables, remove just enough insulation for the bare wire end to fit into the metal end of the plug (no more than about 5mm or 3/16 ). Gently twist the cut ends of multistrand wires to keep them together, and then insert the bare end into the hole. If necessary, trim only the outer part of the cable insulation to allow it to fit into the insulating plug shroud and allow the wire to reach fully into the hole. Next make a secure electrical connection by tightening the screw on to the bare end of the cable. Ensure the red plugs are fitted to both ends of the positive or + conductor and the black plugs are fitted to both ends of the negative or conductor. If you are in doubt consult your Epos dealer. Residents of the European Union may wish to use bare wires into the terminal posts, as 4mm plugs have been outlawed. If bare wires are used, take care to avoid stray strands which can shortcircuit the power amplifier, by twisting the ends together beforehand. Spade type connectors may also be used. Keep any unused plugs safely out of reach of young children. WARNING The 4mm plugs used on modern hi-fi speaker cables should never be inserted into European mains sockets even though they may fit. Needless to say, this is pointless and can be fatal if tried. Make sure that young members of the family are prevented from ever doing this. Page Two CONNECTIONS Warning: Ensure that your amplifier is switched off before you make, break, or change any connections, as damage may occur to your amplifier if speaker cables are shorted. Speakers can be damaged by excessive inputs. Always lower the volume before turning on the amplifier, or making any adjustments to the system (e.g. switching amplifier inputs, or raising or lowering a pickup arm, or turning on a preamp or any other source component). CONNECTIONS TO THE AMPLIFIER Your Epos loudspeakers are equipped with insulated binding posts with excellent electrical contact and current specification. The posts are connected to the individual drivers as denoted on the rear terminal panel. Removable metal l i n k s e n a b l e t h e l o u d s p e a k e r t o b e conventionally wired with a single cable, bi-wired or bi-amped. These techniques often bring benefits in terms of increased clarity and definition. If you are in any doubt consult your dealer or visit the website The sockets on the loudspeaker marked red (+, or positive) on the right side as you look at the loudspeaker rear panel, must be connected to the red ( +, or positive) output terminals on your amplifier, while the sockets marked black ( -, or negative) must be connected to the black ( -, or negative) output terminals on your amplifier. Repeat connections for the right channel. Use good quality cable to connect your loudspeakers to the amplifier. Ensure that the cables from each speaker are of roughly equal length and that any surplus is gathered in a loose hank. Do not coil the surplus tightly. For conventional wiring, leave the metal links in place as factory fitted. If you wish to bi-wire or biamp your loudspeakers, please read the sections which cover these in detail. Once all speaker and signal cable connections have been made, switch the amplifier on with the volume turned down low. Check that the bass and treble sounds come from both speakers. If not, switch off and remake the connections.

3 PHASE If the cables are not connected to each left and right speaker in the same way, i.e. black and red are reversed in one, the effect will be incorrect phasing. This will cause the bass to disappear and the stereo image to move away from the middle to a position outside the two speakers. Correctly wiring the polarity of the speakers will restore the image to between the speakers and provide proper bass. Most speaker cables have a polarising mark, such as a raised bump or writing on the positive wire. BI-WIRING AND/OR BI-AMPING Bi-wiring involves the use of two pairs of speaker cables between your loudspeakers and amplifier. Bi-amping involves the use of two pairs of speaker cables between your loudspeakers and two stereo amplifiers. If you wish to bi-wire or bi-amp your Elan speakers, it is essential that you first unscrew all the binding posts and remove the metal links that join them together. Store them safely for possible future use. Once the links are removed, the drive units will be electrically separate and should be connected to the driving amplifier with individual high-quality cables, as shown. Single wire Bi-wire Bi-amp Use links Remove links Remove links STANDS AND SPIKES For loudspeakers designed for use on stands, best results will be obtained if the stands are rigidly coupled to the floor using carpet-piercing spikes. This will help preserve the outstanding mid-band clarity which is a hallmark of Epos loudspeakers. Epos has designed its own spiked stands for the stand-mount models. The floor-standing models are supplied with their own support plinth and spikes. Four threaded spikes are provided with each floor-standing speaker, together with individual locking nuts. These should be screwed into the metal inserts in the bottom of the plinth. Once these are adjusted to correct the level of the speaker and stop it from rocking, tighten the locking nuts, so as to prevent the spikes from coming loose. POSITIONING AND FINE TUNING Epos loudspeakers are designed to be positioned as specified. Space should be left behind the loudspeakers to allow proper operation of rear-firing reflex ports and to ensure establishment of good stereo image depth. Some experimentation may be necessary to establish the ideal position within your listening room. Each pair of floor-standing speakers is supplied with reticulated foam plugs already in the ports. The foam has been designed to reduce the amount of bass if required, while still allowing bass output from the port and improving the loudspeaker's power handling. Adjusting the front spikes higher will tip the speaker up and can give sonic benefits. Page Three

4 For best bass power and musical dynamics, the foam plugs should be removed from the ports and retained. Begin listening tests by placing the loudspeakers about 20 cm from the rear wall and at least 40 cm of space between each loudspeaker and the nearest side wall. Gradually move them out a little at a time until you achieve the best balance between bass weight and definition. Some rooms and speaker positions can boost the bass too much. If the bass in your room is too powerful, despite trying various speaker positions, we suggest that you try re-inserting the foam. Position the outer surface of the foam near where the straight port joins the outer flare. (If pushed in too far, it could be lost inside the cabinet). If the bass reduction is beneficial, but too great, try cutting the foam across the diameter, about 1/3 of the way from one end. In this way, you can experiment with either no foam damping, 1/3, 2/3 or the whole length (both parts together) until you find the length of foam that best suits your room. Keep the total foam length the same in both the left and right hand speakers. The optimum stereo performance will be achieved when the speakers are positioned 2 metres or more from the listener and about the same distance from one another. Turning the speakers in very slightly towards the listener often helps to stabilize the stereo image. All Epos Elan loudspeakers have been designed to produce a broad listening area. However, the optimum sound balance and stereo image will be enjoyed if your ear level, when seated for listening, falls roughly in line with, or just below, the tweeter. If you can just see the top of the speaker, that will be fine. If, however, the ideal is not attainable or convenient, listening beyond this range will also be enjoyable. Remember, there is no absolute right or wrong - if it sounds good, it is good. PROTECTIVE GRILLES Young children and pets have an affinity for tweeter domes and woofer cones! Also take special care when lifting the speakers not to poke your fingers into the tweeter opening. If the soft tweeter dome is pushed in it should return to its original shape and not affect sound quality, but such rough treatment is not recommended. If in doubt, please contact your dealer. Your Elan loudspeakers are supplied with removable 'audiophile' baffles, which have no grille cloth. For extra drive unit protection, Epos has also supplied optional cloth-covered grilles, packed separately in the main carton. If you wish to use the protective grilles instead, first remove each plain-painted front baffle, by gripping near the small gap between it and the veneered cabinet. Do not insert any tools into the gap to lever it off. There is no need to, and it could damage your speakers! Each front should come off quite easily, with some gentle easing all around, using your finger tips. To fit the cloth-covered grille, hold it with the Epos badge at the bottom and position the smaller of the two holes carefully over and around the tweeter, locate the metal pegs into the rubber sockets and gently push the grille on to the cabinet, evenly all around, until it is fully in place. Please note, unlike most loudspeakers, all the Elan models have been designed to sound much better when used with the grille or plain front baffle. So if you wish to enjoy them at their very best, please ensure either the plain or cloth baffle are in place: do not use with either removed. RUNNING IN Epos loudspeakers require a little gentle use to allow their working components to settle into their proper working condition. Do not be concerned if your new speakers sound aggressive and lacking in low-frequency authority when you first begin to use them. Things will quickly improve. Allow between 24 and 48 hours of normal use before your new loudspeakers can be expected to perform at their best. Page Four

5 POWER REQUIREMENTS Amplifiers with power outputs between those noted in the loudspeaker specifications will generally be adequate, although more powerful amplifiers could be used if care is taken to avoid over-driving the loudspeakers. Always use the volume control with discretion, and reduce the level immediately should the loudspeakers begin to distort, or your ears hurt. Power requirements depend ultimately on listening distance, room acoustics, room size, number of speakers and speaker placement relative to room boundaries. Smaller, less sensitive loudspeakers require more power than larger, more sensitive models. For instance, for listening at 2m (6 1/2 ) distance from the speakers in a 35 cubic metre (1,225 cubic feet) domestic room, a pair of Elan 10s might need about 25W per channel to achieve 100dB SPL, (sound pressure level) whereas the Elan 35s would only need only 10W for the same SPL. The maximum SPL level achievable by the audio system will therefore be set by the maximum available amplifier power and the loudspeaker sensitivity. That is why larger, more sensitive loudspeakers are better suited to larger rooms. So, as a rough guide, the minimum amplifier power we recommend varies from 25W into 4 ohms for the Elan 10, to 10W into 4 ohms for the Elan 35 (please see the individual specifications). Although 100dB SPL maximums are very loud, these would occur only during the very loudest moments. The average SPL could be around 9-14db lower, depending on the style of music. Using amplifiers of lower power than recommended is best avoided because they will restrict the dynamic range. Such amplifiers may also cause damage to the loudspeakers if they are driven beyond their capability in an attempt to obtain high volume levels. This is because the clipping distortion produced when an amplifier is driven beyond its normal output capability can be very destructive. A powerful amplifier operating well inside its capability will generally be less likely to damage your loudspeakers than a lower powered amplifier operating beyond its capacity. (Please note also, that some amplifiers will deliver more than their continuously rated RMS power for short periods, enabling higher maximum SPLs to be achieved in practice). For example, in a 35 cubic metre room, at 2m listening distance, with the amplifier reaching maximums of 100W per channel and playing highly compressed pop music, a pair of Elan 10 speakers could deliver maximum SPLs of 106dB and average levels of 97dB. With classical music, the average level could be much lower, around 92dB. For a pair of Elan 35s with the amplifier reaching 200W per channel, you could add up to 7dB to those figures (at 113dB SPL maximum, with averages of 104dB pop and 99dB classical). Please refer to the SPL vs. Amplifier power chart on page six. The diagonal graph lines show approximate SPLs for each Elan model over a range of power levels in a typical 35 cubic metre room at 2 metres listening distance and with loudspeakers approx 1m to 1.5m from boundaries. Note; this chart covers just one example of listening distance, room size, speaker position and sound damping (for RMS amplifier power into 4 ohms per channel). There will be a wide variation in SPLs in other situations. Smaller sparsely furnished rooms, closer listening, and loudspeaker to room boundary distances produce higher SPLs, (or require less power to produce the same SPL). In such cases the actual SPLs could rise above the diagonal graph lines. Conversely, larger more heavily furnished rooms, and greater distances between speakers and room boundaries, would reduce SPLs (or require more power to compensate). In such cases, the actual SPLs would fall below the diagonal graph lines. Page Five

6 LONG TERM CARE To maintain the appearance of your Elan loudspeakers, simply wipe the veneered and painted surfaces with a barely damp lint-free cloth to remove any dust or finger marks. Do not use spray polishes or cleaners on the fronts. They could damage the drive units. To dust the cloth grille, clean gently with a soft brush. If it becomes so dirty that vacuuming is required, then firstly remove the grille from the loudspeaker, as described above, and use reduced suction. Beware: high suction can damage drive units, especially tweeters. If the speakers are put aside for long periods, store in a dry environment without temperature extremes. NATURAL WOOD This product has been finished with carefully selected and book-matched real wood veneers. We select the best and ensure they are finished to the highest practical standards. Even though Epos speakers have hand matched veneers, no two trees are alike and each pair of speakers may be slightly different in grain, colour and shading. These pleasing variations are your guarantee of the unique and warm charm of your Epos Elan speakers. Each Epos cabinet is finished with a special lacquer which ensures a maintenance free life. Page Six Furniture polish may be used to remove finger marks and dust. Do not use any kind of spirit to clean them. FINALLY Having connected, placed, optimised and run in your loudspeakers, you can relax and simply enjoy the music. With careful use your Epos Elan loudspeakers should give you many years of listening pleasure.
