Breakout Cable Examples:
The example below shows an array of 6x VTX G28 wired using the LK VTX-NL-424 breakout cable. In this configuration
each VTX subwoofer is driven by an independent amplifier channel allowing for flexible cardioid subwoofer circuiting
and a unique delay value (EDS) for each enclosure.
When constructing large horizontal subwoofer arrays, the overall size of an array can have a negative impact on the
subwoofer coverage. The longer the array, the narrower the coverage. Electronic Delay Steering (EDS) is a technique
used to alter the coverage angle of a given subwoofer array by applying a specific pre-calculated delay value to each
subwoofer enclosure. The goal of EDS is to electronically alter the shape of a subwoofer array and widen the coverage
pattern by creating a virtual arc. The radius of the arc controls the radiating pattern of the array and each delay value is
carefully calculated to align all subwoofers to the virtual arc. Hybrid cardioid EDS subwoofer arrays provide even hori-
zontal coverage with 15—25 dB broadband SPL rejection behind the array. Below is an example of a 12x G28 cardioid
subwoofer array and the appropriate delay values for a 90-degree coverage pattern.
