Advice and answers.

A loudspeaker whose coverage is set in software rather than by cabinet geometry. Every EDC S-Series transducer has its own amplifier and processing channel, so one cabinet can form up to four independent beams, each with its own shape, level, delay and source. When the room or the use changes, the coverage is re-aimed from the app instead of by moving hardware.

Up to four independent beams from a single SC or SQ cabinet, each shaped horizontally and vertically. The SS-1 and SS-3 subwoofers produce two. One SC-60 mounted above a video wall can cover the seating in front of it with one beam and the whole room with another.

Most steerable columns control coverage on one axis — usually vertical — and rely on the cabinet's physical width for horizontal coverage. Our algorithms shape the wavefront in three dimensions, so horizontal and vertical coverage, skew and tilt are all set in software, with every transducer contributing full bandwidth in narrow and wide configurations alike. The 3D Beamforming page explains the difference in detail.

Both. The S-Series uses 1-inch soft-dome high-frequency drivers and 5-inch mid-range drivers with no compression drivers, so tonal character is preserved at any level. The same cabinets are installed for station announcements, worship services, corporate presentations and live events.

The SC columns are rated 100 Hz to 20 kHz (±3 dB), and the SQ-90 and the slim SC-30SL, SC-60SL and SC-90SL 80 Hz to 20 kHz. The SS-1 and SS-3 subwoofers extend the system to 25 Hz. Datasheets are on each product page.

Published figures are 95 dB (SC-30), 101 dB (SC-60) and 104 dB (SC-90) at 10 metres for a single cabinet, and 106 dB at 16 metres for the SQ-90, configuration dependent; cabinets cluster horizontally and vertically to form larger arrays that behave as a single source. The figures are long-term peak, dB Leq (linear), and are crest-factor independent because they are peak values. We do not publish the convergent 1-metre maximum the industry usually quotes: converging ninety drivers into a single beam would give roughly 150 dB at 1 metre, which is not a condition these loudspeakers are ever operated in and tells a designer nothing about real coverage.

Yes. Standard cabinets are rated IP55. A weatherised version of every model is available and is rated IP65, with stainless-steel and aluminium hardware, a waterproof grille lining and IP65 network and power connectors. All models operate from −20 °C to +50 °C. These are our own ratings — the enclosures are not third-party tested to IEC 60529, so if a project requires a certified rating, raise it at specification stage.

Every model has an analogue XLR line input and output as standard, with an optional AES3 stereo input or an RJ45 Dante input. Two channels are carried over Dante or AES67, and either can be assigned to any of the four beams. Control is on a separate network port by default; if a project needs control and Dante on a single RJ45, ask us. See the Dante and AES67 page.

Columns carry eight M10 points and can be mounted vertically or horizontally with the U-brackets; subwoofers carry sixteen M10 points and a pole socket; the SQ-90 uses side and rear rigging tubes and the touring rigging frame. Rigging drawings are in Resources. We do not manufacture the rigging hardware — the brackets, tubes and touring frame are made by specialist suppliers, and the working load limits and the standard met come from the maker's documentation. Ask us or your distributor for the certificate covering the item you are specifying.

A monitored version reports transducer, thermal and amplifier faults over the network, and the cabinets carry an inbuilt measurement microphone. This is the version specified for transport and voice-alarm applications. The telemetry interface is not yet documented for third-party systems — see the developer pages for what is and is not specified.

A monitored version of every model is built for EN 60849 voice-alarm systems and reports transducer, thermal and amplifier faults over the network. The loudspeakers themselves are not separately certified — voice-alarm approval is granted to the installed system, not to a component — so we do not hold or publish a product certificate. Bring the certifying body in at design stage and we will supply the technical data the system certification needs.

We support EASE, but not as a fixed GLL library. Because coverage is defined in software, each cabinet has an effectively unlimited number of dispersion patterns, and a handful of pre-baked patterns would not represent the system a consultant is actually designing. Instead the EDC Pro app exports EASE data — 3D balloon data per beam and per array — for the configuration you have designed. Design the coverage in Pro, export it, and model that in EASE.

Yes — clause text for all nine S-Series models, in Resources as an editable Word document and as a PDF. Specify from the Word version so you can edit the clause.

Five years on passive loudspeakers, three years on the non-electronic components of active or powered loudspeakers, and one year on electronic components — amplifiers, power supplies, DSP, processing and control circuitry and network interfaces — wherever they are fitted. All periods run from the date of shipment. Every S-Series model is an active, powered loudspeaker, so the three-year and one-year terms are the ones that apply, and an Extended Service Plan can be purchased for eligible products. The full terms are on the warranty page.

Contact us or your distributor and obtain an RMA before shipping anything — products returned without one may be refused. Have the model, serial number, proof of purchase and a description of the problem ready. Warranty service covers repair or replacement of the product itself; it does not cover getting to it, taking it down, rigging, access equipment, freight, reinstallation or re-commissioning, so budget access and labour into the project rather than the warranty. Full exclusions are on the warranty page.

List prices are published on every product page — from US$7,044 for the SC-30 to US$13,104 for the SC-90 and SQ-90 — which is unusual in this category. We normally holds around twelve units of each model in stock. Project pricing, dealer pricing, lead time and regional pricing come from your distributor or representative.

We sell through representatives across the United States, distributors in the United Kingdom, avcom in Israel and TM Stagetec Systems in Australia and New Zealand. Demonstrations run at the Santa Ana demo theatre by appointment — email sales@edcacoustics.com to arrange one — or on site. Book a technical evaluation.

Amplification, processing and control are inside each cabinet, so there is no external DSP or amplifier rack to buy, power or maintain, and fewer cabinets are typically needed than with distributed systems. Because coverage is software-defined, a room can be reconfigured for new uses without new hardware.

Pro is the full design, modelling and verification environment — audience areas are defined in augmented reality, the system predicts level and response at thousands of listening positions, then measures the room with the iPad microphone and corrects. Rapid uses the same engine for fast deployment. Both push settings to the loudspeakers over the network. See Software.

The Pro and Rapid apps run on iPad and iPhone (iOS 15 or later) and Apple silicon Macs. A desktop design path for consultants, and a developer platform for integrators, are on the roadmap — see Developers.

Yes. EDC loudspeakers are controlled over Ethernet with a documented UDP protocol, and no licence, fee or NDA is required to implement it in your own product. Third-party control covers inputs, levels, mutes, EQ and processing, preset recall, and status — including a pass or fail for every individual transducer in the cabinet. Beam coverage itself is designed in the EDC apps and recalled as a preset, so a control system switches between coverage states rather than steering a beam live. The protocol reference has the detail. We do not publish ready-made Q-SYS, Crestron or Companion modules, SDKs or an AES70 implementation — the protocol is the integration path, and we supply the full packet-level document on request.
