Introduction
Introduction
The L-Acoustics amplied controllers are delivered with onboard rmware and preset library.
Presets of the onboard library can be loaded from the front panel of the amplied controller, or from the
LANetworkManager software application, a management tool dedicated to the remote control and monitoring of a
network of L-Acoustics amplied controllers.
LA Network Manager must be used for updating rmware on L-Acoustics amplied controllers. An up-to-date preset
library is automatically installed with the rmware. Check the L-Acoustics website for the latest version of software,
rmware and libraries.
Operating L-Acoustics amplied controllers
Refer to the LA2Xi, LA4, LA4X, LA8, LA12X, LA-RAK, LA-RAK II, and LA-RAK II AVB owner's manuals.
Installing LA Network Manager
Download the latest release pack from the L-Acoustics website and refer to the LA NWM Installation technical
bulletin.
Updating rmware on an L-Acoustics amplied controller
Refer 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).

Gain structure
The gains of all L-Acoustics factory presets are calibrated with a reference pink noise signal, representative of most
demanding musical programs. The reference input level is 0 dBu (with analog audio source) or -22 dBFS (with digital
audio source).
When feeding L-Acoustics amplied controllers at this input level, L-Acoustics loudspeaker enclosures provide the sound
engineer 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 same
format. With default output gain settings (0 dB), all enclosures reach their limits for the same program level. Apply a gain
adjustment of -4 dB for smaller format enclosures when used along with bigger format L-Acoustics enclosures.
Headroom for SB15m
SB15m 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 SB118
To provide 8 dB of headroom, the output gain of some subwoofer presets is adjusted in preset library 6.0
compared to previous versions.
This update aligns the L-DRIVE activity between subwoofers and full range loudspeakers for the same reference
pink noise signal.
When updating presets in Session les using older versions of the preset library, adjust gains as follows to keep
the 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 dB
Electro-acoustic coupling
Each recommended loudspeaker conguration provides a coherent sound source, by implementing a loudspeaker system
in a specic deployment pattern and with dened factory presets.
L-Acoustics factory presets ensure the coupling between the different transducer sections, whether it is internal coupling as
in 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 predened channel sets.
Channel sets have been dened for the presets dedicated to active loudspeaker enclosures and to some specic
loudspeaker congurations. A channel set maintains a coherent coupling by linking several output channels for the setting
of routing, gain and delay parameters. For example, [LF HF] is a channel set for 2-way loudspeaker enclosure presets,
and [SRSBSBSB] is a channel set for cardioid subwoofer presets.
The Preset Guide describes the recommended loudspeaker congurations for each system, with the corresponding factory
presets and the main resulting acoustic properties.
When applicable, refer to the user documentation of the related system for the limit between coupled and separated
subwoofers.
For some loudspeaker enclosure combinations, it is necessary to adjust the delay values for time-alignment. Refer to
section Pre-alignment delay values (p.66).

Preset design
Frequency response contour
For 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 applications
For 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 applications
For 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 Network
Manager.
The Array Morphing tool provides two parameters, zoom factor and LF contour, that allow users to adjust the response
of a WST system. At any reference listening distance and with any line source length, the engineer can obtain the sonic
signature of a bigger, smaller, closer or further system, and can unify the sonic signature of multiple sources. Refer to the
LA Network Manager Help and Array Morphing white paper for detailed information.
