IntroductionIntroductionThe L-Acoustics ampli ed controllers are delivered with onboard rmware and preset library.Presets of the onboard library can be loaded from the front panel of the ampli ed controller, or from theLA Network Manager software application, a management tool dedicated to the remote control and monitoring of anetwork of L-Acoustics ampli ed controllers.LA Network Manager must be used for updating rmware on L-Acoustics ampli ed controllers. An up-to-date presetlibrary is automatically installed with the rmware. Check the L-Acoustics website for the latest version of software, rmware and libraries.Operating L-Acoustics ampli ed controllersRefer to the LA2Xi, LA4, LA4X, LA8, LA12X, LA-RAK, LA-RAK II, and LA-RAK II AVB owner's manuals.Installing LA Network ManagerDownload the latest release pack from the L-Acoustics website and refer to the LA NWM Installation technicalbulletin.Updating rmware on an L-Acoustics ampli ed controllerRefer to the LA Network Manager help, accessible from the Help menu of the software.This version of the preset guide describes the LA2Xi, LA4, LA4X, LA8 and LA12X preset libraries version 6.6(.2).SymbolsThe following symbols are used in this document:This symbol indicates a potential risk of harm to an individual or damage to the product.It can also notify the user about instructions that must be strictly followed to ensure safe installation or operation ofthe product.This symbol noti es the user about instructions that must be strictly followed to ensure proper installation oroperation of the product.This symbol noti es the user about complementary information or optional instructions.Do not open unless authorized.This symbol indicates the presence of electrical shock hazards.It also indicates that no maintenance performed by the end user requires access to internal components.Preset Guide owner's manual (EN) version 16.05

Preset designPreset designGain structureThe gains of all L-Acoustics factory presets are calibrated with a reference pink noise signal, representative of mostdemanding musical programs. The reference input level is 0 dBu (with analog audio source) or -22 dBFS (with digitalaudio source).When feeding L-Acoustics ampli ed controllers at this input level, L-Acoustics loudspeaker enclosures provide the soundengineer with 8 dB of headroom, except for smaller formats calibrated for 4 dB of headroom (MTD108A, 5XT, X8, 8XT,Kiva, Kilo).This gain structure helps managing power resources of L-Acoustics systems when using different enclosures of the sameformat. With default output gain settings (0 dB), all enclosures reach their limits for the same program level. Apply a gainadjustment of -4 dB for smaller format enclosures when used along with bigger format L-Acoustics enclosures.Headroom for SB15mSB15m presets [SB15 100] and [SB15 100 C] have 8 dB of headroom from preset library version 5.6(.5).[SB15 100 Cx] has 8 dB of headroom.4 dB of headroom are provided when using presets from earlier versions and preset [KIVA SB15].Headroom for K1-SB, KS28, SB28, SB18, SB218 and SB118To provide 8 dB of headroom, the output gain of some subwoofer presets is adjusted in preset library 6.0compared to previous versions.This update aligns the L-DRIVE activity between subwoofers and full range loudspeakers for the same referencepink noise signal.When updating presets in Session les using older versions of the preset library, adjust gains as follows to keepthe same gain chain:[SB28 60], [SB218 60]: 4 dB[KS28 60], [SB 28 100], [SB18 60], [SB18 100], [SB218 100], [SB118 60], [SB118 100]: 3 dB[KS28 100]: 2 dB[K1SB 60]: 1 dBElectro-acoustic couplingEach recommended loudspeaker con guration provides a coherent sound source, by implementing a loudspeaker systemin a speci c deployment pattern and with de ned factory presets.L-Acoustics factory presets ensure the coupling between the different transducer sections, whether it is internal coupling asin active loudspeaker enclosures, or external coupling as when several loudspeaker enclosures are combined.Users can adjust preset parameters on top of factory settings and for prede ned channel sets.Channel sets have been de ned for the presets dedicated to active loudspeaker enclosures and to some speci cloudspeaker con gurations. A channel set maintains a coherent coupling by linking several output channels for the settingof routing, gain and delay parameters. For example, [LF HF] is a channel set for 2-way loudspeaker enclosure presets,and [SR SB SB SB] is a channel set for cardioid subwoofer presets.The Preset Guide describes the recommended loudspeaker con gurations for each system, with the corresponding factorypresets and the main resulting acoustic properties.When applicable, refer to the user documentation of the related system for the limit between coupled and separatedsubwoofers.For some loudspeaker enclosure combinations, it is necessary to adjust the delay values for time-alignment. Refer tosection Pre-alignment delay values (p.66).6Preset Guide owner's manual (EN) version 16.0

Preset designFrequency response contourFor the X Series coaxial loudspeaker enclosures, there are two distinct contours: the standard preset, for all applications except stage monitor applications the MO preset, dedicated to stage monitor applicationsFor legacy coaxial loudspeaker enclosures (XT and MTD Series), there are three distinct contours: the FR presets, for most of FOH applications the FI presets, for spoken word, classical music, jazz, or ll systems the MO presets, for half-space loading conditions, typically monitor applicationsFor current WST systems, there are one or two distinct contours: the main preset, ensuring a reference FOH contour to the line source with usual deployment parameters the FI preset, dedicated to loudspeaker enclosures used as a ll system (for some systems only)The oldest WST systems inherit from a legacy preset structure ( HI and LO presets).If necessary, users can adjust the sonic signature of L-Acoustics systems through the Contour EQ tools in LA NetworkManager.The Array Morphing tool provides two parameters, zoom factor and LF contour, that allow users to adjust the responseof a WST system. At any reference listening distance and with any line source length, the engineer can obtain the sonicsignature of a bigger, smaller, closer or further system, and can unify the sonic signature of multiple sources. Refer to theLA Network Manager Help and Array Morphing white paper for detailed information.Preset Guide owner's manual (EN) version 16.07
