LA 10.4D

Our power plant: Control your applications like a pro!

A light in the dark? We developed the LA 10.4D so that you remain in control at all times. A 4-channel amplifier with more than 4x 2,500 W specifically for line array systems of the L-Line. Lots of power in a tiny space – for up to 16 speakers per amp! The user-friendly software sets everything up immediately.

Your personal chief assistant allows for full performance monitoring. In this amplifier, signal processing is optimised – all parameters can be set centrally and the operation of the system is constantly monitored.

With this core piece, you will keep the overview: Your Power Station features a high-quality processed integrated DSP, a Dante® network audio connection and remote network control. To optimise the system, you can count on reliable tools: Limiters, parametric EQ to adapt to the room, Delay and FIR filtering.

Now we come to the pulse: The LA 10.4D is a four-channel amplifier system with a capacity of 4x 2,500 W per channel. Thanks to the minimum impedance of 4 Ω, you can connect up to 16 speakers.

The intuitive user interface ensures your supremacy. Optimise your personal work flow by means of the network control! Adjustments can be saved just how you like it. The professional Audio Toolkit saves valuable time. The multiple-users compatibility ensures maximum security – the settings are stored in the amp and not in the computer. Simply reposition, done.

Future-proofed software allows you to plan, analyse and run your application. Control all parameters centrally. Monitor what is happening on your computer. In short, this amp is your power plant. Enjoy your full supremacy!

Features

Flexible connectors

This power amplifier accommodates the three most common analogue connections. Specifically: 2-channel XLR inputs with link outputs, in conjunction with 3-pin Phoenix MSTB inputs. And in the output area: 3x Neutrik SPEAKON® connectors, next to 4-pin Phoenix MSTB connectors. Enjoy maximum flexibility!

DSP integrated security

The 48/96kHz DSP processor provides precise Filter, EQ and Limiter settings for all L-line speakers. Thus, you have full control at the mixing desk. Thanks to the speaker Presets, EQ controller and Delay set up your system quickly and easily.

Network-ready, touch screen and memory

Control of the system is done centrally from the cockpit via the computer. If necessary, the chief assistant supports a 3.5 inch display. It provides all the information and is intuitive to operate. Touch the screen and turn the knob… The library will deliver safe, consistent results.

An overview that makes sense

Change important settings even in low-light environments. Thanks to the LED lighting, you can quickly access the mute buttons and the most important parameters are always in plain sight.

Everything in the flow

Easy troubleshooting thanks to log files. Floating point processor. High-resolution signal flow. High dynamic range. High signal-to-noise ratio. The LA 10.4D turns you into a Master of the Universe.
