The SSOUNDS Event 4A is a compact, self-powered column PA: two column tops, carrying eight 4″ full-range drivers in total, on a single 15″ powered subwoofer. The subwoofer holds the Class-D amplification (2 × 800 W) and a 48 kHz / 24-bit DSP, controlled over Ethernet, with Dante available as an option. The tops cover 120° horizontally with a tight 30° vertical from their stacked line, and when the two are stacked they couple for 124 dB. It runs 40 Hz to 18 kHz and packs down into a flight case or a padded jacket for the road.

Event stands for all-in-one PA systems. A complete PA in one system: tops, subwoofer, amplifier, DSP and networking in a single package, so the whole rig runs from a power lead and a network cable and is set up for an event in minutes.

Measurement conditions

Maximum SPL is the peak level at 1 m, driven with pink noise at crest factor 4 to the clipping point of the recommended amplifier, with the SSOUNDS system preset applied. Full-range enclosures are specified under free-field conditions; figures marked half-space are specified over a reflecting plane, the condition subwoofers are deployed in, which adds approximately 6 dB.
Frequency response is specified on axis at 1 m in a free field. The tolerance the figure is referenced to is stated alongside it; where no tolerance is given, the figure is the −6 dB bandwidth.
Coverage angles are nominal −6 dB values averaged across the pass band. Per-octave directivity data is available from SSOUNDS system design support for prediction and modelling.
Net weight excludes packaging, flight case, accessories and optional rigging hardware.
Dimensions are stated in millimetres and exclude protruding rigging hardware, handles and connector panels unless noted.
All figures are typical values for production units specified under the conditions above. Individual units may vary within published tolerances.

Directivity

Directivity computed by the SSOUNDS system prediction engine from this product's driver complement, the same dataset the printed data sheet uses. 1/24-octave band-power resolution; values are dB relative to on-axis.
