XR1001-1Class D Mono Power Amplifier RMS 500W x1 (4Ω) RMS 1000W x1 (2Ω) Variable Low-pass Filter Infrasonic Filter Bass Boost: 0dB to +18dB (40Hz) Speaker Level Input Signal Sensing Turn-on Wired Remote Level Control Included Dimension: (W)12-5/8” x (H)2” x (D)6-5/8” Weight: 7.1lbs (3.1kg) Max Power : 2000W Low Pass Filter : 50 - 200 Hz (-12/-24 dB / oct.) Bass Boost : 40 Hz (0 - +18 dB) Infrasonic Filter 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.
