Analog Lab Musical Analog Instruments eo Xpass Filter User Manual v1 0 www analog lab com Xpass Filter User Manual v 1 0 Congratulations and thank you for buying the Analog Lab Xpass Filter Before to go further in this user manual you just have to read carefully all the recommendations concerning the safety and installation instructions l Safety and installation recommendations Il Introducing the Xpass Filter III Wiring and audio configurations IV Functions General view Section Vu meter and input level Section B Bypass Section C Waveforms selector and modulations Section D Lfo frequency Section E Modulation Amount Section F Filtering modes amp Xpass zone Section G Resonance Section H Cutoff frequency Section I Attack Release Section J Output level Section K Headphones V Warranty VI Analog Lab contacts VII Blank sheet VIII Personal notes Safety and installations recommendations Use only the Xpass Filter with the supplied power supply If you need any other power supply contact the Analog Lab services which information are in the sixth paragraph of this user manual The Xpass Filter doesn t have a on off switch Only the power supply is needed to switch on the Xpass Filter In any case you wontt need to open the Xpass Filter None of the intern components can be manipulated by the user Only the Analog Lab technical staff is able to m
4. Bandpass Filter Notch mode contrarily to the bandpass mode it filters a central field of frequencies to pass the above and below frequencies of it Ff Notch Filter Output frequencies Notch Filter These four filtering modes are representing the complete panel of frequencies filtering and permit an exhaustive panel of settings We organized the filtering modes around a potentiometer called Xpass and a commutation switch called Bandpass But we have gone further this idea The potentiometer called Xpass is a new and very important function on this product Turned completely on the left the Xpass Filter is in lowpass mode Lp If you turn it completely on the right it applies the hipass mode All the potentiometer course between permits progressively to go from the lowpass filter mode to the hipass filter mode This characteristic is an Analog Lab exclusivity very powerful creative and allows very musical transitions The commutation cap below called bandpass permits to switch from the bandpass mode to the notch mode described above The Xpass potentiometer takes its place when the filter is in bandpass mode highlighted led When you switch off this led you are in notch mode and the Xpass potentiometer is no more active Section G Resonance The resonance is an harmonics generator It permits to affect the sound very particularly and creatively Try to adjust this parameter very progressively The resonance
5. ake technical interventions This is a condition of warranty canceling Take care to install the Xpass Filter on a flat and free workspace to avoid moisture or humidity and shock risks In its use take care with the potentiometers and switches The Xpass Filter is an instrument that generates very powerful harmonics that can damage audio hardware Take care with your settings the headphones and the lt cue gt functions can avoid you bad surprises for your monitors and your audience Il General view The Xpass Filter is a very powerful filter built only with analog technology so important for our ears and musicality It permits you to make a lot of different works on the frequencies form the very thin work on frequencies to tremendous and creative effects The Xpass Filter is a mono filter that accepts all the stereo sources Both sides of the stereo will be mixed before the filtering unit All the sound levels are accepted instrument line and phono You can plug guitar bass electromechanical keyboards Rhodes Wurltizer Clavinet etc analog or numeric synthesizers samplers expanders track recorder cd players turntable computer etc Important You ll find many different audio levels with the cds You ll just have to compensate this different levels with the input and output potentiometer This concerns principally the manipulation that consists in switching vinyl or cd in a parallel wiring configuration IIl Wiring

8. ncel all the parameters of the unit except the input and output levels The sound source passes thru the Xpass Filter transparently e Section C Waveforms selector and modulations This selector is one of the most important element of the Xpass Filter It s used to select the modulation mode on the frequency treatment described further in the Section F It a four position selector with two waveforms sine and square an envelope follower and an attack release mode Reminder Lfo is an abbreviation of low frequency oscillator that is a cyclic waveform control which frequency determines its speed In the case of the Xpass Filter this speed is variable with the Ifo frequency potentiometer The Ifo gives expressivity in all the sound design works or the musical movements The envelope follower is a mode that permits to apply the frequency treatment on the signal audio waveform The expressivity and reactivity of this mode is impressive and permits to apply very creative effects The attack release mode permits in relation with the sound level to apply the frequency treatment with a variable attack and release These descriptions are quite abstract on the paper but you ll understand and ear all these modes uses and subtleties very quickly e Section D Lfo frequency If you choose to work on the Ifo mode sine or square this potentiometer permits to slow or accelerate the waveforms period by increasing or decreasing its frequenc
9. y If you turn right the potentiometer the Ifo speed will be accelerated Like the others this potentiometer is very precise and sensitive At the beginning of its course there is a no speed zone very useful when you need to cancel the speed effect in quick manipulations Here s an illustration of this frequency variation SA AAA Modulation frequency variation e Section E Modulation Amount The lt Mod Amount gt potentiometer adjusts the amplitude modulation it s the distance between the lowest and highest point of the modulation This function is used on all the filter modulations Modulation amplitude variation e Section F Filtering modes amp Xpass zone The Xpass Filter is a multimode filter Each mode detailed below Hipass mode Hp it permits to let the frequencies to pass above a point filtering the frequencies below this same point This point is variable and it s called lt cutoff frequency gt Section I Hi Pass Filter PA Output frequencies Hipass Filter Lowpass mode Lp contrarily to the hipass mode it lets the frequencies to pass below the cutoff point and it s filtering the frequencies above Low Pass Filter HITS Output frequencies Lowpass Filter Bandpass mode Bp this filtering mode permits to a central frequency field to pass and the frequencies above and below it are filtered lIIIIIIIIIIIIIIIII Input frequencies p Bandpass Filter AAA Output frequencies
