LiYA X4 8-Channel / 4-Zone Class D Amplifier – 8 × 100W at 4Ω with Bluetooth, Optical & Built-In DSP

The LiYA X4 is a professional multi-zone Class D amplifier designed for larger residential, hospitality and commercial distributed-audio installations. With eight powered channels divided across four independent zones, the X4 allows multiple rooms or listening areas to be powered from a single high-efficiency amplifier.

The amplifier delivers 100 watts per channel into 4-ohm speaker loads across all eight channels, providing a total rated channel output of 800 watts. Its Class D architecture is designed to provide high power density while reducing heat generation compared with many traditional amplifier designs.

The X4’s four-zone architecture provides independent A1, A2, A3 and A4 output selection. This allows installers and users to manage speaker zones independently, making the amplifier particularly suitable for large homes, restaurants, retail environments, offices, hotels and other multi-room installations.

Built-in Digital Signal Processing (DSP) provides internal audio signal processing, while the amplifier covers a manufacturer-specified frequency response of 20Hz to 20kHz.

The X4 offers a broad range of digital and analogue source options including MP3 playback, USB, Bluetooth, AUX, CD, DVD and Optical input modes. Bluetooth provides convenient wireless playback from compatible mobile devices, while Optical connectivity allows integration with compatible televisions and digital source components.

A universal AC 100–240V, 50/60Hz power supply supports installation across different mains-voltage regions. With eight powered channels, four-zone control, integrated DSP and multiple source options, the LiYA X4 provides a flexible central amplification solution for complex multi-room audio systems.
