In a live and streamed event for partners and press at the Philharmonie de Paris (video below), L-Acoustics announced the extension of its integration-specific products with the introduction of the new LA7.16i amplified controller, Soka colinear source loudspeaker and SB6i subwoofer, and L-ISA Ambiance that provides virtual acoustics enhancements, and they were featured at the ISE 2022 show in Barcelona and will be presented at the upcoming InfoComm 2022 in Las Vegas in June (booth W3011 and demo room W209).
The LA7.16i offers 16 x 16 architecture in a 2U chassis with Milan-AVB redundancy, with each of the 16 output channels stated to deliver up to 1300 watts at 8 ohms and 1100 watts at 4 ohms. It also introduces L-SMART, a suite of power management technologies designed to allow integrators to mix and match any L-Acoustics loudspeaker onto one amplifier.
L-SMART uses proprietary predictive modeling algorithms to manage the power supply unit (PSU) and the individual amplification channels. Hardware sensors within the amplifier supply real-time information, which is analyzed by the DSP to dynamically match loudspeaker system needs. The PSU can then provide high short-term peak power or lower power over longer hold times. This energy is delivered to the class-D output stages to help assure optimum system performance.
“Getting this kind of power capacity into this kind of space is an incredible breakthrough in R&D. No other amplified controller offers the channel density of LA7.16i in this power class,” says Germain Simon, head of product and technology marketing at L-Acoustics. “Before LA7.16i, you’d need 8U to generate the same power as LA7.16i. Conversely, you could fit 16 channels in 4U, but you’d be giving up power. That kind of compromise is no longer necessary with LA7.16i.”
The LA7.16i offers loudspeaker monitoring, protection and management, GPIOs, terminal block connectors, and a backup 24-volt DC input that enables the DSP card to continue functioning if mains power is lost. Smart mains current limiting and circuit breaker emulation are also included. It supports Milan-AVB network redundancy and is remotely controlled and monitored using LA Network Manager or third-party systems like Q-SYS and Crestron. Each unit provides a summation matrix with 16 inputs that can be selected from up to 128 Milan-AVB channels (16 streams of 8 channels each) on EtherCON connectors. Milan-AVB redundancy is standard. Additional qualifications are underway to complete Milan certification and to support the AES67 audio network protocol.
Meanwhile, Soka integrates nine 3.5-inch MF drivers and three one-inch HF transducers to impart 140-degree horizontal coverage coupled with controlled 26-degree vertical directivity. Soka and SB6i have a depth of 3.9 inches/99 millimeters, designed to be enclosed in-wall or discreetly mounted on-wall.
Soka is stated to deliber 124 dB over a bandwidth that extends down to 70 Hz when used with the full-range preset. Using the SPL preset, Soka is stated to 130 dB down to 100 Hz.
With two 6.5-inch neodymium LF drivers and the L-Acoustics Laminar vent technology found in the company’s concert-grade subwoofers, SB6i is a 4-ohm enclosure that can operate down to 29 Hz and produce as much as 114 dB, again via two presets, matching coupled or decoupled configuration with the main system.
The L-ISA Ambiance virtual acoustics enhancement system uses L-Acoustics loudspeaker systems, microphones, and a 3D Room Engine powered by the L-ISA Processor II and is designed to help transform the acoustic properties and qualities of a venue space to match the desired atmosphere. A beta version is currently being used by a select number of pilot projects, and the public version will be available in Q1 2023.
L-ISA 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. It 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.
“An L-ISA Ambiance system provides flexibility to a venue, opening up acoustic enhancement to a wider market, without the need to alter the look of the space,” explains Jordan Tani, product and technology marketing engineer at L-Acoustics. “Installing Ambiance not only gives a space future-proof flexibility, but it also opens up creative possibilities for designers to construct—and reconstruct—the aural feel of the space to their desire.”
