New processors, loudspeakers at PLASA 2011

In a further round-up of highlights from the Earls Court showfloor, L-Acoustics introduces the ARCS II line source, Lake the LM44 processor, Lab.gruppen the E Series, and Midas the PRO2 systems.

In a further round-up of highlights from the Earls Court showfloor, L-Acoustics introduces the ARCS II line source, Lake the LM44 processor, Lab.gruppen the E Series (pictured), and Midas the PRO2 systems.

Intended form medium to large rental products, the new ARCS II constant curvature line source system from L-Acoustics is based on a two-way active design. Due to ship in October, ARCS II is said to offer a number of improvements over the previous generation, primarily L-Acoustics’ K1 grade transducers for increased SPL (140 dB) and lower weight (50 kg). It also features a new front grill for enhanced durability and appearance, and is driven by a single factory preset to efficiently accommodate any application.

An ARCS II line source can be deployed either horizontally or vertically, with a coverage angle proportional to the number of enclosures in the array (N x 22.5°). On the other plane, vertical or horizontal respectively, the ARCS II line source provides an asymmetrical coverage angle of 60° (20°/40°). The orientation of the ARCS II enclosures within the array determines asymmetric distribution, allowing the use of a horizontal ARCS II line source either for upward or downward coverage.

Building on the LM 26, the new LM 44 standalone system processor from Lake provides four analogue inputs and four analogue outputs. It accommodates eight-in/eight-out AES3 and four-in/eight-Dante digital audio transport, while the Mesa EQ configuration utilises four Mesa modules, each with an independent input mixer and output signal processing chain. Suitable for FOH applications, including as a mix-matrix and full system EQ, LM 44 is said to offer a cost-effective, scalable alternative to more expensive processors in applications where only a 4 x 4 analogue I/O configuration (or multiples of this) is required. Additionally, LM 44 can be operated in Contour mode configuration (two Contour modules), allowing for deployment as a loudspeaker crossover processor.

Elsewhere within the TC Group of brands, Lab.gruppen showcased its new E Series of installation-oriented power amplifiers. Aimed at bread and butter contractor applications, the E Series models offer compact 2-channel, 1U designs. Incorporating an IDEEA (IntelliDrive Energy Efficient Amplifier) technology Class D output stage, the E Series comprises three 1U two-channel power amplifiers: the E 12:2 (600W @ 4 ohms), E 8:2 (400W @ 4 ohms) and E 4:2 (200W @ 4 ohms). Higher per-channel outputs are possible with asymmetrical loading and careful setting of the proprietary Rail Sensing Limiter (RSL) circuit.

“The E Series is a game-changer for us in the sense that we will be able to reach new applications and customers,” said Klas Dalbjorn, product research manager at Lab.gruppen. “We have never really looked at introducing a low-cost install product before.”

Meanwhile, sister company Tannoy exhibited its new VX and VXP Series of loudspeakers, along with the VQ live loudspeaker range, which was displayed through UK distributor JHS and Co. VQLive is fully integrated with on-board amplification, DSP and network control (via Tannoy’s proprietary VNET system), meaning that there is no need for additional outboard power and processing.

Midas introduced the new PRO2 and PRO2C live audio systems. The PRO2, complete with stagebox and power supplies, costs just over €20,000; the PRO2C, similarly equipped, is priced at €15,000. “Now our customers will be able to buy a digital Midas for no more than a regular mixing console,” commented Richard Ferriday, brand development manager.

The two models – which are to be built at The Music Group’s Chinese factory – feature similar core specs: they both have 56 mic/line inputs with Midas mic preamps, 64 input channels and 32 analogue outputs (including two stereo local monitor outputs), and feature the same components and finish as the rest of the PRO series. The compact PRO2C can be thought of as the PRO2 with the left-hand section (which contains eight input faders) removed; its footprint is just 750mm x 850mm.

The VeniceF-16R 16-channel rack mount was also new from Midas. Described as a variant of the VeniceF ‘digi-log’ ultra-compact mixing console, the VeniceF-16R comes complete with FireWire multi-channel digital audio interface, the full functionality and sound quality of the Midas XL3 EQ and filter section, Midas mic preamps, 100mm faders, increased channel and input count, a dual 7×2 matrix, and a reorganised master section layout. It is also bundled with Propellerhead recording and processing trial software.
