XR401-4 eXcelon 400-Watt 4-Channel Amplifier

Rich and Immersive High-Resolution Audio

High-Resolution Audio is high-quality sound that exceeds CD standard. High-resolution audio captures and beautifully expresses all the details of your favorite music. Through ultra-high and low frequencies, immerse yourself in a rich and high-quality sonic experience.

High Performance Parts

Special capacitors and inductors have been carefully selected for the digital amplifier’s LC filter, which is essential for achieving high-resolution audio. These high-performance parts reduce noise and distortion and ensure excellent sound quality.

Deep Bass Sound

By using a down-firing subwoofer and superior technologies, the audio system generates high-quality sound and powerful bass, while still being compact.

Enhanced Signal to Noise Ratio

The feedback value of the current XR Amplifier has been optimized to improve the S/N ratio. As a result, the noise level has been reduced by up to 40%.

Specialized Noise Circuit

The noise reduction system employs a special layout that separates the analog circuit, digital amplifier circuit and power supply circuit. This keeps interference between the circuits to a minimum, decreasing noise and thereby achieving high performance and sound quality.

Wired Remote Control

The wired remote control allows you to adjust the volume of a subwoofer when connected to the head unit.
