P1 AVB processor and measurement platform

L-Acoustics P1 is an AVB processor and measurement platform. Remote controlled from LA Network Manager 2.6

Windows/macOS software together with L-Acoustics amplied controllers, its 20 inputs / 18 outputs dual core DSP

platform provides a comprehensive solution for mixing desk selection, signal processing and distribution over AVB

networks, AES/EBU or analog lines.
P1 includes four microphone inputs and an advanced library of acoustic measurement functions for efcient system

tuning. The workow is twofold: the impulse responses of all parts of the system are acquired from multiple audience

locations; then, optimal system tuning is directly determined from LA Network Manager 3 with automatic delay nder

and EQ modelization ofine algorithms. Thanks to a powerful database architecture and online integration with amplied

controllers, the System Engineer can easily select and apply the settings that will achieve the desired result in accordance

with the Soundvision design, the audience characteristics, and the artistic objectives.
