6. f a circuit that takes the bass signal and emphasises harmonics within it to produce a bright zingy top end It is not an EQ circuit it actually synthesises new harmonics adding these to the original sound The best way to describe this is that it is similar to the top end zing you get from a new set of strings This has a LEVEL control and can be switched in or out with the front panel switch Used in moderation you will find it adds a lot of bright high harmonics to the sound giving definition and clarity not achievable in any other way GRAPHIC EQUALISER The GRAPHIC EQUALISER section operates by boosting or cutting the level of signal at various frequency points throughout the frequency range With the sliders set on OdB in their centre click position no alteration is made to the signal Moving any one of the sliders up will increase or boost the signal at the frequency marked below the slider Moving the slider down will decrease or cut the signal at that frequency The GRAPHIC EQUALISATION can be switched in or out with the front panel switch A carefully designed GRAPHIC EQUALISER is a very flexible way of varying the sound of a bass guitar and if properly used will provide an extremely powerful method of tone shaping for your instrument Because of the flexibility and massive BOOST and CUT potential of this particular GRAPHIC it is important to know how to get the best from it Firstly a few things not to do and the
7. reasons why Do not boost or cut all frequency bands as this will have the same effect as increasing or decreasing the overall volume level without affecting the tonal characteristic of the sound 2 Do not use excessive bottom 30 to 40Hz boost on the graphic unless your speakers can handle it Very few speaker systems are capable of handling frequencies as low as 30 and 40Hz with any degree of efficiency N B Boosting at 30Hz for instance will not add to the perceived amount of bottom end in the sound it will only make your speakers flap to no useful effect In fact boosting at 100Hz or 180Hz will have the apparent effect of adding far more bottom end than boosting at 30 40 or even 60Hz 3 Do not use excessive top 10 to 15kHz boost this will add mostly hiss to the sound as there is very little signal output at this frequency from a bass The 30Hz slider has been provided to allow precise tailoring at very low frequencies This slider should be used to CUT not Boost the 30Hz to a level that allows the speaker system to work at its maximum efficiency USEFUL OBSERVATIONS The fundamental frequency range of a regular four string bass guitar is from 41 2Hz bottom E string to around 392Hz two octaves up on the G string not a very wide range Obviously a lot of harmonics are produced when playing and these can extend up to 5kHz and more The attack portion of the note also produces other high frequencies when the string is first s

10. truck This attack can be emphasised by boosting the top end However because of the fairly small range of frequencies from a bass by top end we mean between 2 6kHz and 5kHz You will find that by boosting at 5kHz the attack will be emphasised whereas by boosting at 1 3 and 2 6kHz you will bring out the harmonics in the note Above this frequency range you will find it is better not to boost the signal as this will mainly emphasise any hiss present This hiss will not be masked by the bass signal when playing due to the very small amount of bass guitar frequency content at 10 to I5kHz Use the 30Hz and 40Hz sliders sparingly unless you have a massive stack of speakers available and the power amplifiers to drive them You will find that rolling off the bottom end by using these two sliders will allow you to play at a far greater volume level without the speakers complaining Try to keep the graphic sliders balanced around OdB and in a smooth flowing curve from one slider to the next and remember that after adjusting the graphic you may need to re set the INPUT GAIN DI The DI or DIRECT INJECT socket is a balanced low impedance XLR output intended for connection into the Microphone Input on one channel of a mixing desk Continued over This is to carry the signal to the PA system for larger gigs It is balanced and low impedance to ensure that no noise is added to the signal on the way to the mixer The level of this signal has been set to b
