MARTIN AUDIO

W8L Longbow
Large Scale, Three-Way Line Array Enclosure

The Martin Audio W8L Longbow is an evolution of the successful W8L line array system. It brings a new level of performance to the most demanding sound reinforcement applications such as outdoor festivals, sports stadiums and the largest arenas.

Since the launch of the W8L, Martin Audio has developed a patent pending technology, which provides an exceptional degree of control over the curvature of the high frequency vertical wavefront. By coupling this technology with significant advances in high frequency device design we have created a quad-driver, high frequency system with an impressive 10dB greater output capability.

PLM™ – Powered Loudspeaker Management™ Introducing the new PLM 14000

The PLM Series

PLM Series: A revolution in professional audio

In the wake of the global success of the PLM 10000Q Powered Loudspeaker Management system, Lab.gruppen have developed a powerful new addition to the range, the PLM 14000. Built around a two-input, two-output platform optimized for high-power requirements, the PLM 14000 pumps a massive 7000 W per channel into 2 ohms and 4350 W per channel into 4 ohms, making it ideal for demanding subwoofer and low-end applications.

As with the two-input, four-output PLM 10000Q, the new PLM 14000 integrates Dante networked audio distribution, Dolby Lake drive processing, and load verification with real-time performance monitoring into a single 2U hardware unit plus unified software controller. The PLM Series is now the exclusive hardware platform for new Dolby Lake processing, and the addition of the PLM 14000 enables even more complete and extensive system solutions built around this unique combination of technologies.

Lab.gruppen’s PLM Series is a seamless fusion of cutting-edge technologies from two innovators in live audio: Dolby Lake and Lab.gruppen. Each PLM product combines groundbreaking Dolby Lake signal processing – the world standard for flexibility and sound quality – with an amplifier platform based on the power density, sonic purity, and demonstrated reliability of Lab.gruppen’s FP+ Series.

Intelligently merged, these complementary technologies add up to more than the sum of their parts. The result is Powered Loudspeaker Management (PLM), a comprehensive loudspeaker drive system integrating crossover, delay, equalization, limiting, audio networking, and power amplification.

It all adds up to unprecedented user control, reconfiguration flexibility, and system tuning precision. In addition, PLM’s revolutionary load verification and performance monitoring features assure extended reliability for all system components, loudspeakers included.

The expanded PLM Series now affords users total flexibility in re-configuring racks for power-hungry subwoofers, line arrays, or stage monitors.
