Meyer Sound UP-4slimMeyer Sound has introduced the UP-4slim ultra-compact installation loudspeaker – ’a slender new solution for applications that demand impeccable performance and exceptional power-to-size ratio together with elegant aesthetics’.

The UP-4slim incorporates Meyer Sound’s IntelligentDC technology, integrating active operation with the installation ease of low-voltage systems. It is the first IntelligentDC multi-way loudspeaker to be housed in an all-aluminium enclosure. It uses a three-way system comprising two 4-inch cone drivers, a 1-inch metal dome tweeter, a three-channel amplifier and dedicated signal processing. The two cone drivers work in parallel at lower frequencies, with one rolling off in the midrange to prevent comb-filtering effects. The HF driver is mounted on a conical waveguide to produce a smooth and consistently wide 100° dispersion pattern. The integral three-channel amplifier produces 500W total output power.

The UP-4slim’s frequency response is 65Hz to 18kHz, and its aluminium enclosure is ported, damped and braced to minimise resonance while maintaining uniform response to the lower frequency limit. Real-world linear peak acoustic output is 110dB SPL using unfiltered pink noise. As with the other 14 loudspeakers in the IntelligentDC range, the UP-4slim accepts balanced audio and 48V DC from a remote, rackmount MPS-488HP power supply and signal distribution unit. Connections are via a single five-conductor cable (such as Belden 1502) with termination on a five-pin Phoenix connector. Conduit for the cabling is not required in most jurisdictions worldwide. The optional RMS Remote Monitoring System provides a display of loudspeaker operating status (Windows or Mac).

The internal components of the UP-4slim are identical to those in Meyer Sound’s highly successful UP-4XP, which is housed in a slightly larger, wood-based enclosure. However, the dedicated signal processing in the UP-4slim has been modified and refined to attain optimum performance in the slimmer aluminium housing.

The UP-4slim may be installed using the optional U-bracket or mounting yoke. The M8-threaded top and bottom rigging plates also can be fitted to the optional external pole mount for portable applications. Other options include custom colour matching and weather protection for outdoor installations. Applications for the UP-4slim include foreground/background music and paging in commercial installations, delay and fill systems in performance venues, and portable systems for smaller rooms. It is also ideal for deployment in Meyer Sound’s Constellation active acoustic system.

‘Today’s high-end installation market is driven almost as much by appearance as by performance, and the UP-4slim makes no compromises on either point,’ says R&D VP and chief loudspeaker designer, Pablo Espinosa. ‘When surface mounted, its understated appearance blends discreetly with any room décor, and where soffit mounting is preferred it will slide into tight spaces where other loudspeakers offering comparable performance simply won’t fit.’
