L-Acoustics LA4X User Manual

Technical description
• LA4X amplied controllers with HARDWARE INFO ID4 or higher (in MONITORING & INFO menu) support AVB.
One AVB stream of up to eight channels may be connected to LA4X. LA4X retrieves up to four channels from this stream.
Each Ethernet port uses a high speed data transfer protocol up to 1 Gb/s and supports the IEC 61883-6 AM824 and
AAF PCM32 stream formats with stream frequencies of 48 kHz or 96 kHz.
The amplied controller synchronizes its audio clock on the clock used by the talker through the incoming stream.
LA4X embeds an AVB bridge and may therefore be used to create an AVB network.
DSP architecture
The proprietary algorithms allow optimum performance and protection of each individual transducer of the L-Acoustics
systems for an even more natural, transparent and realistic sound experience.
• The DSP engine is a 32-bit oating point DSP at 96 kHz sampling rate providing an enhanced dynamic range since
it does not generate calculation clips like a xed point DSP.
• A dedicated engineering approach combining IIR and FIR lters generates perfectly linearized phase curves and
signicantly improved impulse responses.
• The 4 × 4 matrix architecture offers exibility for various system congurations.
• A delay of up to 1000 ms can be set for each output channel.
• The L-DRIVE transducer protection system offers advanced protection by simultaneously monitoring the excursion and
the temperature of the transducer.
• With a complete factory preset library and the possibility to create additional user presets, the ash memory
provides a quick access to all the usual L-Acoustics speaker system congurations (refer to the Preset Guide).
