L-Acoustics LA4X 4-Channel Amplified Controller

เพาเวอร์แอมป์ 4 ชาแนล L-Acoustics LA4X,  4 x 1,000 W RMS into 4 or 8 ohms, Built-in EQ station with 8 IIR, 4 FIR linear phase EQ filters Array morphing, A/D converters and integrated DSP processor, Flexible 4 x 4 matrix with 4 in and 4 out

The LA4X is an amplified controller based on a 4-input by 4-output architecture and an exclusive green power module providing maximized efficiency. With LA4X, L-Acoustics® speakers can get all the benefits of self-powered speakers, while keeping the versatility of the separated amplification approach.

For applications requiring a high count of loudspeaker enclosures with optimized cost of amplification, the LA4X can efficiently operate as a conventional amplified controller driving speakers in parallel from its four amplification channels, with the added benefit of the 4 inputs when using passive loudspeaker enclosures.

Packaged in a 2U chassis, LA4X integrates powerful DSP resources with built-in loudspeaker optimization tools and the proprietary L-DRIVE system to protect the loudspeakers and the amplified controller. In addition to analog and AES/EBU inputs, LA4X features Milan-AVB audio network connectivity
