The L-Acoustics LA-RAK II AVB offers twelve channels of amplification in a flyable touring rack. The LA-RAK II is equipped with three LA12X amplified controllers, two LS10 AVB switches and power/signal distribution panels. This rack provides a plug and play, reliable solution for seamless networked audio redundancy based on the Milan protocol.
The L-Acoustics LA-RAK II AVB comes with three-phase 32A IEC input and link connectors, allowing two LA-RAK II AVB units to be linked together.
The LA12X is a four-channel amplified controller designed to power the largest loudspeakers in the L-Acoustics catalogue. LA12X features a proprietary switch mode power supply (SMPS) with DSP-controlled power factor correction (PFC) capable of delivering 12,000 watts of output power with record hold times. Based on a 4×4 architecture, these amplifiers offer both flexibility to power a high density of passive loudspeakers and a powerful amplification for large format active enclosures. The four inputs are available in analogue, AES and AVB. Four cascaded 24-bit and 96 kHz A/D converters at the front end yield an impressive encoding dynamic of 130 dB.
The LS10 AVB Switch is a plug and play Avnu-certified AVB switch that integrates seamlessly within the L-Acoustics ecosystem to further simplify connectivity, uniting audio and control distribution. The LS10 distributes audio and control via front EtherCon connectors enabling long distance optical links.
