The Audiocenter D4.2K-D is a 4-channel Class D power amplifier rated at 4×500W at 4Ω or 2×1000W bridged at 8Ω, built with integrated BrainCore™ DSP processing (48kHz/24-bit, IIR and FIR filters, 15-band parametric EQ per input, 10-band per output, per-channel delay and limiting) and Dante audio networking. It accepts Dante, AES/EBU, and analogue inputs simultaneously with configurable matrix routing. Network management is handled via BrainCore NET software, which supports up to 250 devices from a single platform. The unit occupies 2U of rack space and weighs 8.5kg. It is supplied and supported in New Zealand by Edwards Sound Systems, an Auckland-based AV company that has stocked Audiocenter products since 2010.

Edwards Sound Systems supplies and installs pre-programmed turn-key event lighting packages for bars, schools, clubs, and community venues across Auckland. Built around the Kontrol192 DMX controller — supporting up to 12 fixtures at 16 channels per fixture — each package is custom-specified to the venue and pre-programmed with scenes, sound-activated modes, and labelled fixtures before delivery. Fixture options include the Event LITE PAR19X12L for indoor stage applications and the IP65-rated PAR12X20H-IP for outdoor and mixed-environment use. Packages include all stands, cabling, and mounting hardware, and are designed to be operated by non-technical staff without a dedicated lighting operator.

Every school hall depends on the visuals working the moment the lights go down, whether that's assembly, prize-giving, or opening night of the school production. A tired projector with fading lamp hours and a washed-out image in a hall full of ambient light isn't just an inconvenience, it's the moment a principal is standing in front of 400 people hoping the screen holds up. See how Edwards replaced exactly that risk at a leading Auckland independent school, installing a permanent 8-metre Lampro LED screen custom-built for the hall. The full job, cabling, mounting, programming, and commissioning, was handled by our in-house team, so nothing was left half-finished or dependent on a third party turning up. The result is a screen that now covers everything the hall is used for, assemblies, presentations, movie nights, and live events, with an image quality no projector in that space could match, and nothing for staff to calibrate, maintain, or worry about once it's in.
