L-Acoustics unveils LA7.16i amplified controller

Created to improve flexibility and efficiency, especially in multichannel scenarios, L-Acoustics has launched the LA7.16i offering 16x16 architecture in a 2U chassis with seamless Milan-AVB redundancy. Each of the 16 output channels delivers up to 1,300W at 8Ω or 1,100W at 4Ω. The amplified controller will drive both current and future L-Acoustics loudspeakers for more efficient and sustainable installations. It offers flexibility to meet real-time power needs, energy efficiency and the ability to address multichannel and hybrid applications, including the L-ISA Ambiance room enhancement software.

Current amplifier technology is dimensioned to power all channels simultaneously over extended periods of time. However, in real-world applications, this demand is rare. The amplified controller technology introduced with the LA7.16i uses energy more effectively, offering a lower cost-per-channel solution and an electronic unit that consumes 30% less energy when idle.

With the LA7.16i, L-Acoustics has also introduced L-SMART, a suite of advanced power management technologies that allow designers to mix and match any L-Acoustics loudspeaker onto one amplifier. L-SMART uses proprietary predictive modelling algorithms to manage the power supply unit (PSU) and the individual amplification channels. Hardware sensors within the amplifier supply real-time information, which is analysed by the DSP to dynamically match loudspeaker system needs. The PSU can then provide extremely high short-term peak power or lower power over longer hold times. This energy is delivered intelligently to the advanced Class-D output stages, reportedly assuring optimum system performance at all times. The LA7.16i can drive any L-Acoustics speaker up to K2, enabling high-resolution amplification and processing of large-format speakers with less system budget.

L-ISA Ambiance uses L-Acoustics loudspeaker systems, microphones and an advanced 3D Room Engine powered by the L-ISA Processor II. Ambiance empowers acousticians, theatre and audiovisual consultants, composers and sound designers to transform the acoustic properties and qualities of a venue space to match the desired atmosphere. Ambiance enhances experiences by better connecting audiences and performers to each other and to their shared space.

The L-ISA Ambiance virtual acoustic enhancement system uses hardware – speakers, amplifiers and processors – that are already a necessary part of modern venues. Adding strategically placed microphones to capture the existing acoustical energy of a space, Ambiance processes signals from the mics through the L-ISA Room Engine that’s built into the L-ISA Processor II, where reflections can then be individually managed with separate EQ, time and space parameters, empowering a sound designer to create a desired sound atmosphere for the space. L-ISA Ambiance can be controlled via the L-ISA Controller on both Mac and Windows platforms, through the built-in configurations on the Processor or with Q-SYS and Crestron third-party control systems.


Adding to its range of solutions designed to meet the demands of the installation market, L-Acoustics has also introduced the Soka and its companion subwoofer, the SB6i. Inspired by the success and design principles of the Syva, the Soka integrates nine 3.5-inch MF drivers and three 1-inch HF transducers to impart a wide 140° horizontal coupled with a highly controlled 26° vertical directivity. The Soka and SB6i have been designed to be easily enclosed in-wall or discreetly mounted on-wall. Despite its diminutive size, the Soka delivers 124dB over a wide bandwidth that extends down to 70Hz when used with the full-range preset. Using the SPL preset, the Soka offers an even higher 130dB down to 100Hz. With two 6.5-inch neodymium LF drivers and the L-Acoustics Laminar vent technology found in the manufacturer’s concert-grade reference subwoofers, the 4Ω SB6i can operate down to 29Hz and produces as much as 114dB, again via two presets, matching coupled or decoupled configuration with the main system.
