7.1 KUDO
®
system configuration
The choice of a KUDO
®
system configuration should be the result of an electro-acoustic study conducted by an expert
(System Engineer or Audio Consultant). However, this will not be discussed here as sound-design aspects are beyond
the scope of this manual. This study can rely on the simulations modeled in SOUNDVISION software, yielding electro-
acoustic predictions which take into account the enclosures manufacturer data and particular situational usage, as well
as the projected environment.
Two operation modes (“FULL RANGE’’ and “HIGH-PASS’’), each one associated with a set of factory presets, will
allow building all the common configurations (C, LR, LCR, distributed…).
The KUDO
®
enclosure can be used as a standalone system in the “FULL RANGE’’ mode or in combination with the
L-ACOUSTICS
®
SB118 or SB28 subwoofers in the “HIGH PASS’’ mode.
For each mode a distinction is drawn between the [50], [80], or [110] presets as they respectively match
K-LOUVER
®
directivity settings of 50° (25°/25°), 80° (25°/55° or 55°/25°), or 110° (55°/55°).
The development of dedicated presets has been made possible since the L-ACOUSTICS
®
LA8 new
integrated system approach is offering a DSP per four channel amplifier allowing to easily recall the
correct preset upon the chosen K-LOUVER
®
setting.
The LA8 also features linear phase FIR filters allowing different presets to be simultaneously used
within the same array. Since no phase shift occurs between enclosures such blend of settings is now
possible without breaking the wavefront generated by the DOSC
®
waveguides.
Note: The latest version of the preset library can be supplied by an L-ACOUSTICS
®
authorized representative and is
also downloadable on the L-ACOUSTICS
®
web site at www.l-acoustics.com.
7.2 “FULL RANGE” mode
7.2.1 Description
The "FULL RANGE" mode features a 25 Hz or 40 Hz high-pass filter combined with optimized LF shelving equalization
to provide maximum low-end frequency extension.
In this mode significant low-end energy can be obtained from the KUDO
®
itself allowing standalone configuration
without additional subwoofers in a large number of applications.
7.2.2 Connecting the KUDO
®
to the LA8
The first KUDO
®
enclosure is connected to the CA-COM
®
connector of an LA8 amplified controller. A maximum of
two additional cabinets can be grouped in parallel with the first one. Therefore a single LA8 amplified controller can
drive up to 3 KUDO
®
enclosures (see Figure 8).
Driving 3 KUDO
®
enclosures with a single LA8 amplified controller will solicit system resources to their
limits and can trigger the thermal protection feature of the controller. This configuration has to be
avoided when the power requirements are extreme and continuous over a long period.
Note: The system resources are optimized when the line source contains a multiple of 3 KUDO
®
enclosures. As a
general rule if the array does not contain a multiple of 3 KUDO
®
enclosures, the amplified controllers solicited with the
smaller load should power enclosures dedicated to long throw application (typically located on top of the array) as the
acoustic signal should be reinforced in the HF domain.
