7.3 “HIGH-PASS” mode
7.3.1 Description
The "HIGH-PASS" mode features a 60 Hz high-pass filter for the low section combined with optimized low frequency
shelving equalization allowing for perfect coupling with the L-ACOUSTICS
®
SB118 or SB28 companion subwoofers.
The combined system operating range is lowered down to 32 Hz or 25 Hz, respectively, for applications requiring an
extended sub-low frequency response.
The choice of the subwoofer model and KUDO
®
to subwoofers ratio will depend on the application and desired system
overall tonal balance. For most applications the recommended ratios are 3 KUDO
®
for 2 SB118 or 1 SB28. For
applications requiring an increased energy in the sub-low frequency range the recommended ratios become
2 KUDO
®
for 2 SB118 or 1 SB28.
The “HIGH-PASS” mode can also be suitable in standalone applications without subwoofers that do not require a
maximum low-end frequency extension.
7.3.2 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 9).
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.
