Following the LA7.16 multichannel fixed installation amplified controller, L-Acoustics has announced its road-ready counterpart, the LA7.16 for live productions.
The LA7.16 amplified controller aims to meet real-time power needs while offering a new level of efficiency and sustainability in modern touring applications. The high-density 16x16 architecture in a 2U-high format powers more line array speakers than any similar-size amplifier, meaning fewer racks on tour, which translates directly to energy and time savings along with the ability to address multichannel and hybrid productions.
LA7.16 responds the needs of the L-Acoustics L Series, whose L2 and L2D elements require 16 high-power amplifier channels and 16 DSP channels. LA7.16 boasts a touchscreen and an encoder wheel to rapidly set up initial parameters, and a single SC32 connector on the rear for connecting to the loudspeakers.
The new LA-Rak III touring rack houses three LA7.16 amplified controllers, offering 48 amplification channels and 48 individual DSP channels totalling more than 60kW peak power in a 9U-high rack, with two LS10 switches to support MilanAVB redundancy.
‘LA7.16, with its best-in-market efficiency, is the perfect partner to the newly launched L Series,’ says, Director of Product Management, Electronics, Scott Sugden. ‘The power capacity and energy efficiency are breakthroughs in design and will help rental providers to deploy faster and realise real-life economies in transport and deployment.’
LA7.16 uses L-Smart, a suite of advanced power management technologies that allows 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 the system needs. The PSU then provides extremely high short-term peak power, or lower power over longer hold times. This energy is delivered intelligently to the class-D amplifier output stages for optimum system performance at all times.
LA7.16 can drive any L-Acoustics loudspeakers up to K2, enabling high-resolution amplification and processing of large-format speakers with less system budget.
