System operation
Recommended: SSOUNDS D24X, one channel per XTO S218F (4 Ω) with the S218 preset loaded. Cardioid presets are supplied for three- and four-box columns. A flown subwoofer column is normally run as its own zone, so its arrival time and its cardioid rear rejection can be set independently of the ground-stacked arcs.
Architectural & engineering specification
The subwoofer shall be of the SSOUNDS XTO S221F type, configured as a flown subwoofer module. The subwoofer shall be measuring 1,300 × 580 × 900 mm. The subwoofer shall be covered by the manufacturer's two (2) year limited warranty and shall be supplied by SSOUNDS or an SSOUNDS-authorised distributor. No alternate shall be accepted without prior written approval of the consultant or specifying engineer.
Safety & compliance
Read this section before specifying, installing or operating this product. It summarises the safety requirements set out in full in the product documentation supplied with the unit; where the two differ, the product documentation takes precedence.
- Suspension & rigging
- Overhead suspension is potentially hazardous and must be carried out only by trained and competent personnel using SSOUNDS-approved hardware, within the working load limits and array configurations published in the relevant SSOUNDS rigging documentation. Never exceed the stated number of enclosures per array or the stated splay limits. Inspect all rigging components, pins and retaining clips before every deployment and withdraw from service any component that is deformed, corroded or of unknown history. Secondary safety attachment is required where local regulation calls for it. SSOUNDS accepts no liability for systems suspended using non-approved hardware or outside published limits.
- Sound pressure level & hearing
- This equipment is capable of producing sound pressure levels that cause permanent hearing damage. Do not operate at high level in close proximity, and ensure that operators, performers and audience exposure complies with applicable occupational noise-exposure regulation. Provide hearing protection where exposure limits may be exceeded.
- Environment & mechanical
- Unless a published IP rating states otherwise, this product is intended for indoor use or for outdoor use under cover, and must be protected from rain, standing water and prolonged direct sun. Ensure ventilation openings are unobstructed. Stack, pole-mount and transport only as described in the product documentation, and secure the product against toppling wherever the public has access.
- Disposal
- At end of life, dispose of the product and any packaging in accordance with local regulation for electrical and electronic equipment. Do not dispose of electronic components in general waste.
