Se-Audiotechnik LA 10.4D

Se-Audiotechnik LA 10.4D system amplifier

To stay in control at all times, SE AUDIOTECHNIK developed the LA 10.4D.

The 4-channel system amplifier with 4x 2,500 W has been designed to further expand the SE product portfolio.

Speaker presets provide the best possible performance for a variety of applications. This feature allows you to build custom setups with perfectly matched sound characteristics. Your personal assistant enables full performance monitoring. In this amplifier, signal processing is optimized and all parameters can be set centrally with full and flexible control.

This amplifier features built-in high-quality DSP, Dante® network audio connection (optional) and remote network control. To optimize the system, you can count on reliable tools such as EQ, Delay and FIR filters.

All parameters can be adjusted with the SE Mission Control software or autonomously on the amplifier using the LCD touch screen. Intuitive user interface ensures your supremacy. Adapt the system to your personal workflow. Use custom controllers with group control and cross parameters. Define what you want to have on hand to interact directly with the L-Line system. Save your setting and always be ready for the show. Custom presets and controllers are stored in the amp.
