LiYA X3 3-Channel LCR Class D Power Amplifier – 190W/Ch at 4Ω with Built-In DSP

The LiYA X3 is a high-performance three-channel Class D power amplifier designed specifically to drive the Left, Center and Right loudspeakers of a premium home theatre system. By dedicating identical amplification to all three front channels, the X3 provides a strong foundation for a cohesive cinematic front soundstage.

Each of the three amplifier channels is rated at 190 watts into a 4-ohm load, providing substantial output capability for demanding floorstanding, centre-channel, in-wall and architectural loudspeakers. Across all three channels, this represents 570 watts of summed rated channel power.

The X3 uses high-efficiency Class D amplification, allowing substantial power output while reducing unnecessary heat generation compared with many conventional amplifier designs. This makes it particularly suitable for custom AV racks and dedicated cinema systems.

Built-in Digital Signal Processing (DSP) provides internal signal management for improved control and speaker protection. LiYA specifies a frequency response of 40Hz to 20kHz, covering the essential operating range required for front-channel home theatre reproduction.

Each channel supports Global or Local input selection. Global mode allows a common signal source to be distributed as required, while Local mode enables individual line-level signals to be routed independently to each amplifier channel. This flexibility makes the X3 useful for both conventional LCR systems and specialised custom-install configurations.

The amplifier accepts AUX / line-level analogue input signals and uses a universal AC 100–240V, 50/60Hz power supply for compatibility across different mains-voltage environments.

With three identical high-power channels, built-in DSP and flexible input routing, the LiYA X3 is especially suited to upgrading the front Left, Center and Right channels of dedicated home cinema systems where additional amplifier headroom is required beyond an AV receiver’s internal amplification.
