29. rum of the signal and that the signal is normal programme material Test tones from oscillators and the like are not applicable The lower figure is the minimum we consider necessary to achieve reasonable listening levels without audible distortion in the smaller room less than 60 m or 2000 cu ft The higher the power you use the less likely you are to experience amplifier clipping You can often tell how good an amplifier is at driving complex speaker loads by looking at its power rating into both 4Q and 8Q loads The nearer the ratio is to 2 1 the better as it indicates a good current capability In order to reduce the effect the cable has on the frequency response of the speaker to inaudible levels the impedance of the cable at all frequencies measuring both positive and negative conductors in series should be kept as low as possible and certainly below 0 1Q At low frequencies the DC resistance of the cable is the dominant factor and you should choose a gauge of wire sufficient to achieve the impedance requirements over the length of cable you need to use At mid and high frequencies the inductive component of the impedance can dominate the DC resistance This and other properties influenced by the detailed construction of the cable become important Ask your dealer for advice on the best cable for your needs 8 AFTERCARE Veneered cabinet surfaces usually only require dusting If you wish to use an aerosol cleaner r
30. stems one set of terminals feeds the bass drivers and the other the midrange and tweeter In 2 way systems one set of terminals feeds the bass midrange driver and the other the tweeter Separation of the signal paths to each section of the speaker can improve imaging and the resolution of low level detail and allows the user to optimise the cable to the frequency range of use Bi wiring involves the use of two separate 2 core cables from the same amplifier one to each pair of terminals This is the minimum we would recommend but should you prefer to single wire perhaps during the initial set up procedure or because you do not want to see a multitude of cables in the room you must connect both positive and both negative speaker terminals together The ear is at its most sensitive in the midrange SO we recommend that when single wiring you connect the cable from the amplifier to the terminals that directly feed the midrange driver Bi amplification goes a stage further and involves the use of two separate power amplifier channels for each speaker It is not the same as having a fully active system because the speaker s internal passive crossover is still used If using bi amplification ensure that each amplifier channel has the same gain otherwise you will change the balance of the speaker Check the absolute polarity Some amplifiers invert the signal and a mixture of different tyoes may cause a dip in the overall
31. tages Most multi channel music is recorded with home entertainment in mind and is monitored using monopole surround speakers whatever the multi channel recording format This enables better location of side and rear images although the formation of such images is never quite as precise as it is between the front speakers Most films are originally balanced for cinemas where a large number of speakers spread around the auditorium are used to create the surround sound field In that case there are more surround speakers than there are discrete channels of information and a less precise image is created that gives an all enveloping effect Dipoles and similar diffuse speakers are better at recreating this type of sound field in the home but using fewer speakers to do it Image positioning with these types of speaker is never as precise as it can be with monopoles However they do have the advantage of making it easier to balance the system for a larger listening area You may well receive conflicting advice from different sources on the best type of surround speaker to use The truth is that there is no one perfect solution for all situations and the final choice for any given application will be influenced by several criteria some of which may have a degree of conflict DS8S only Within the 800 series the DS8S is the only speaker to offer dipole operation In fact this specialist surround speaker has the advantage of o
