XR901-5Class D 5 Channel Power Amplifier RMS 60W x4 + 400W (4Ω) RMS 75W x4 + 600W (2Ω) Variable Low-pass Filter Bass Boost: 0dB to +18dB (40Hz) Speaker Level Input Signal Sensing Turn-on Wired Remote Level Control Included Dimension: (W)10-1/4” x (H)2” x (D)6-5/8” Weight: 5.2lbs (2.4kg) Operating Voltage: 14.4V (11 - 16 V allowable) Current Consumption: 80 A Rich and ImmersiveHigh-Resolution AudioHigh-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 PARTSSpecial capacitors and inductors have been carefully selected for the digital amplifier’s LC filter, which is essential for achieving highresolution audio. These high-performance parts reduce noise and distortion and ensure excellent sound quality DEEP BASS SOUNDBy 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 RATIOThe 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 CIRCUIT DESIGNThe 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 CONTROLThe wired remote control allows you to adjust the volume of a subwoofer when connected to the head unit.
