L-Acoustics LA4X Amplified Controller
Description
The LA4X is a compact, 2U amplified controller designed for rental applications that require flexible routing, efficient amplification, and integrated loudspeaker protection. It combines a 4-input by 4-output architecture with a proprietary green power module to deliver high-efficiency Class D amplification and onboard DSP tools, including the L-DRIVE protection system.
Key Features
- Four inputs, four outputs: Route analog, AES/EBU, or Milan-AVB audio with 4-channel input flexibility and 4 speakON outputs for straightforward speaker deployment.
- Networked audio: Dual-port Gigabit etherCON with Milan-AVB support, accepting up to 8 channels from a single AVB stream at 48 or 96 kHz.
- Multiple input options: AES/EBU XLR inputs (2 x AES/EBU, 44.1–192 kHz) shared with analog XLR inputs, with active XLR link outputs and bypass relay for redundancy.
- Power and performance: 1000 W total output with all channels loaded, high-efficiency Class D amplification, frequency response ±0.25 dB (20 Hz–20 kHz at 8 Ω, 60 W), THD+N < 0.05% at 60 W.
- Dynamic range and noise: >110 dB output dynamic range (digital input), noise level < -70 dBV (A-weighted).
- Integrated DSP and protection: Built-in loudspeaker optimization tools and the L-DRIVE system for reliable loudspeaker safeguarding in rental environments.
Use Cases
- Medium-format live sound and corporate AV where efficient, rack-mounted amplification and remote networked audio are required.
- Installations and touring racks that benefit from combined DSP, multiple input formats, and high channel density in a 2U footprint.
- Deployments using passive L-Acoustics enclosures, taking advantage of parallel speaker driving from four amplification channels.
