LiYA X2 4-Channel / 2-Zone Class D Amplifier – 4 × 100W at 4Ω with Bluetooth, Optical & Built-In DSP

The LiYA X2 is a high-efficiency four-channel Class D amplifier designed for multi-room residential audio and commercial distributed sound systems. Delivering 100 watts across each of its four channels at 4 ohms, the X2 provides a total of four powered speaker channels while supporting two-zone operation from a single compact amplifier.

The dual-zone architecture provides selectable A, B and A&B operating modes. This allows audio to be played through Zone A, Zone B or both zones simultaneously, making the X2 suitable for installations such as living and dining areas, bedrooms, offices, retail spaces, hospitality environments and other multi-room applications.

LiYA integrates Digital Signal Processing (DSP) directly into the amplifier to optimise signal handling and overall audio performance. The amplifier covers the full 20Hz to 20kHz audible frequency range and uses high-efficiency Class D amplification for strong output with reduced heat generation compared with many conventional amplifier topologies.

The X2 provides a wide selection of source options including MP3 playback, USB, Bluetooth, AUX, CD, DVD and Optical input modes. Wireless Bluetooth connectivity allows compatible phones, tablets and other devices to stream audio directly, while the Optical input provides a convenient digital connection for compatible televisions and digital source equipment.

A universal AC 100–240V, 50/60Hz power supply allows the X2 to operate across a wide range of mains-voltage environments. Its combination of four powered channels, dual-zone switching, digital and analogue connectivity and integrated DSP makes it a flexible central amplifier for modern custom-install audio systems.
