Easy, clever, powerful
We developed the LA 10.4D so that you remain in control at all times. The 4-channel system ampliﬁer with 4x 2,500 W is tailormade for our SE product portfolio, from line array systems to subwoofers, point source loudspeakers and monitors.
Speaker presets unleashes the best possible performance and are also designed for various applications. This feature enables you to build custom setups with perfectly matched sound characteristics.
Your personal assistant allows for full performance monitoring. In this ampliﬁer, the signal processing is optimized and all parameters can be set centrally with full and flexible control.
With this core piece, you will keep the overview: Your power station features a high-quality processed integrated DSP, a Dante® network audio connection (optional) and remote network control. To optimize the system, you can count on reliable tools: EQs, Delays and FIR ﬁltering.
All parameters can be adjusted with the SE Mission Control software or stand-alone on the amp by using the LCD touch screen. The intuitive user interface ensures your supremacy. Adapt the system to your personal workﬂow. Use Custom Controllers with cross-parameter and group control. Deﬁne what you would like to have on hand to directly interact with the L-Line system. Save your setting to and be always ready for the show. Presets and Custom Controllers are stored in the ampliﬁer.
Control LA 10.4D via the intuitive touch screen or SE Mission Control software. Factory device and speaker presets help to setup your system. Create Custom Controllers and adopt the system to your workflow.
The LA 10.4D system amplifier provides a Dante® network audio connection (optional), remote network control access as well as connectors for AES/EBU and analog signal input. With linked outputs and Neutrik speakON® NL4 connectors, you remain always flexible.
The LA 10.4D system amplifier comprises floating point DSP for sound and system tuning. Make use of EQs, Delays, Filters, Factory Device and Speaker Presets, User Presets, Custom Controllers and much more.
LA 10.4D provides a high-resolution signal flow, a high dynamic range, a high signal-to-noise ratio and 10,000 W of power in total for true and clear sound projection.
