LiYA X7 7-Channel Class D Power Amplifier – 190W/Ch at 4Ω with Built-In DSP

The LiYA X7 is a high-performance seven-channel Class D power amplifier designed for premium home theatre, surround-sound and custom-install audio systems. With seven identical high-output amplifier channels in a single chassis, the X7 provides the power required to drive a complete multichannel speaker system with consistent performance across every channel.

Each amplifier channel delivers 190 watts into a 4-ohm speaker load. Across seven channels, this represents 1,330 watts of summed rated channel power, providing substantial headroom for demanding tower speakers, centre speakers, surrounds and architectural in-wall loudspeakers.

The X7 uses high-efficiency Class D amplification to deliver substantial output while reducing unnecessary power loss and heat generation compared with many conventional amplifier designs. This makes it well suited to dedicated AV racks and high-output home cinema systems.

Built-in Digital Signal Processing (DSP) provides internal audio signal management and supports precise system integration. LiYA specifies a frequency response of 40Hz to 20kHz and describes the amplifier circuitry as providing limited / ultra-low distortion.

Each of the seven amplifier channels provides Global / Local input selection. Global mode allows a common master source to be distributed across channels, while Local mode allows an independent line-level signal to be assigned to an individual channel. This provides significant flexibility for home theatre, multi-room and custom-install applications.

Audio input is provided through AUX / line-level connectivity, making the X7 suitable for connection to compatible AV processors, surround preamplifiers and AV receivers equipped with pre-out connections.

A universal AC 100–240V, 50/60Hz power supply supports operation across a wide range of mains-voltage environments. With seven high-power channels, flexible signal routing and built-in DSP, the LiYA X7 provides a powerful central amplification platform for premium multichannel audio systems.
