XR601-1Class D Mono Power Amplifier RMS 400W (4Ω) RMS 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)8-11/16” x (H)1-3/8” x (D)6-5/8” Weight: 3.5lbs (1.6kg) Operating Voltage: 14.4V (11 - 16 V allowable) Current Consumption: 46 A Dimensions (W x H x D): 220 x 35 x 169 mm (8-11/16 x 1-3/8 x 6-5/8) Warranty: 2-Year HIGH PERFORMANCE PARTSSpecial 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 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.
