4. You don t need to buy speaker wire that costs as much as your speakers to get some benefit from wire size select a finely stranded speaker cable and dress the cable ends to prevent hairs or stray conductors from shorting across the terminals If your amplifier will not directly accept that size of cable you can trim down the cable size at the amplifier end Ensure that the binding post retaining nuts are screwed down firmly without stripping or over tightening them 2 4 OBSERVING POLARITY You already know about connecting the positive terminal on the amplifier to the positive terminal on the speakers and ensuring that both channels are in phase by checking to ensure that there s more bass with both speakers on and not less bass Absolute polarity is a bit trickier to confirm Absolute polarity is the maintenance of a positive pressure wave from the microphone capsule to the listening room A kick drum for instance has the drum skin whacked by the foot pedal and it pushes the air which pushes the microphone diaphragm which goes through the electronics and should eventually come out of the speakers as a positive pressure wave which should have the speaker cones moving towards you just like the drum skin It turns out that you can t trust a conventional recorded source to test this because there is no way to confirm that absolute polarity was maintained it can even change from track to track This isn t a trivial thing especial
5. and the supplier Keep all the packaging as this will show evidence of excessive handling forces It is also a good idea to keep the packaging if possible for future transportation 2 2 PRELIMINARY RECOMMENDATION Initially we would like to give a word of warning on high sound levels which these speakers are capable of generating over sustained periods of time Levels over 95 dB for 8 hours per day will eventually cause permanent hearing loss Because Tannoy monitors have very low levels of time amplitude and frequency distortion it is not always obvious that the sound level is high while working with them For continuous exposure we recommend the occasional use of a sound level meter capable of integrating the sound level over a period of exposure according to noise control standards This should be used just to check that noise levels are always within safety limits 2 3 CONNECTING YOUR SPEAKER The types of cable used to connect the speakers to the power amplifier will marginally affect the sound The cross sectional area of the cable should be large enough so as not to affect the damping factor generally a cable with a cross sectional area of 2 5 mm2 or greater is recommended The lower the resistance of the cable between the amplifier and the speakers the better the damping factor acting on the speaker This has been covered in every audio magazine that has ever been written about speakers so we won t beat it to death here

7. A stereo five band parametric is better than a stereo 15 band that is better than a stereo 1 3 octave You may not realise that in all but one or two brands of 1 3 octave equalisers all 30 filters are in series There is a minimum transit time through each filter of some 25 microseconds plus just a bit of decay time for each filter Even with the equaliser set flat it does not behave like a straight piece of wire in the time domain If you don t need to equalise your monitors then don t hook an equaliser up to them at all A subtle bit of reduction in the mid bass where the console or table top will give you a rise perhaps a bit of tailoring to taste here or there As a general rule for this application you should never need more than 6dB of control range and you should never see two adjacent filters with more than 6dB of difference between them Over equalisation can reduce system headroom and introduce phase distortion resulting in greater problems than cures Always check out the result of equalisation by listening to well recorded vocals or speech 4 0 PRECISION 6 AND 8 DIMENSIONS 260 5mm 50 0mm 10 4 2a PRECISION 6 iN 107 9mm Aya 186 0mm 734 287 5mm 50 8mm j 11 2 ETEN N j 107 9mm Ay

9. at the same distance to the mix position as the main front speakers As the subwoofer LFE channel only produces low frequencies it is difficult to localise its position by ear As a result it could effectively be situated anywhere in the room though optimum performance will be gained by placing the subwoofer in the same plane as the main front speakers The LFE channel is set at a level 10dB higher than the other channels when mixing therefore it is important to apply the same in any playback situation NOISiIIDSa2A TANNOY 3 2 BASS PORTS The Precision monitors bass ports are located on the back panel You should keep the back panels at least 150mm 6 away from the nearest wall surface to avoid an overblown bass sound If you cannot avoid being close to the wall you may want to consider plugging the port tubes on your loudspeaker with a closed cell foam rubber plug friction fit for a full seal This will overdamp the speakers making them more suitable for a 2Pi environment for example against a wall 3 3 EQUALISATION Our feeling is that you shouldn t need to equalise monitors at all in a well designed monitoring environment apparent variations in the monitor response should be fixed through room design or placement But we realise that equalisation is sometimes a necessary evil If you have a choice of equalisers for monitor applications less is more The fewer the number of filters the better the equaliser will sound

12. ly when you re using a true stereo microphone setup or trying to accurately place things in your mix This is something that should be rigorously checked with every microphone and every signal line in a studio but the first step would be to use the kick drum test described above with a few microphones If you don t believe it can make a difference set up a little test using a mix you know and flip the polarity of both channels at the same time while listening to the same program imaging vague imaging imaging vague imaging Hear Believe 2 5 POWER AMPLIFIERS The power amplifier should be reasonably well matched in power to the power rating of the speakers see specifications The use of a powerful amplifier i e in excess of the recommended figure provides headroom which is useful especially for highly dynamic programme materials Due of the high peak power handling of Tannoy monitors responsible use of even more powerful amplifiers should not represent a danger to the speakers if the amplifiers are not overdriven 3 0 INSTALLING AND POSITIONING When choosing a suitable location for the monitors bear in mind that the physical mounting of loudspeakers can have a large influence on performance For best results the monitors should be mounted on a rigid structure supported on four pads making contacts with the laminated panel The use of soft pads rubber Sorbothane or Blu Tak is recommended Ensure that the conso
