3) CLASS D is a totally different amplifier, which is called a "switching amplifier". Carvin CLASS D amplifiers incorporate both a "switching power supply" and a "switching amplifier", which saves a considerable amount of weight and power. The CLASS D output features a high frequency switching signal, which is a 500,000Hz square wave. This is modulated with an input audio signal and then rolled off to produce a linear high power audio output. The advantage of CLASS D is its 94% efficiency eliminating heat and substantially reducing the AC line power requirement. BASS AMPS: BX500, BX1500 DCM MODELS: DCM1000L, DCM2000L (Feb 2010 model), DCM2004 MIXERS: XP800L, XP1000L, RX1200L, C1648P CLASS SUMMARY: While Class A/B has been the standard for years, Class D has the advantage of being more efficient. Both classes sound great and the RMS equivalent is the same for either Class. However, the THD (distortion) output of a Class D amp will change according to its output impedance. Example: 8 ohms: .08%, 4 ohms .1%, and 2 ohms .25%. Typically, you would not hear any difference between 2 or 4 ohms especially for subwoofers so the operation efficiency of Class D can become more important than the THD difference. CONCLUSION: Carvin's Class A/B and Class D power amps and mixers are engineered to the highest standards to provide years of quality performance. Continuous full power is assured from high-grade 6063-T5-aluminum heat sinks and high-current components. Heavyduty connectors provide a positive connection to your cables, ensuring every watt gets to your speakers. Carvin's "SMT" Surface Mount Technology utilizes surface mounted components to prevent parts from shaking or vibrating loose, and precision 1% tolerances guarantee your settings will be accurate every time. Fire retardant FR-4 military spec circuit cards feature double-sided copper to guard against noise and radio frequencies (RF) interference. Carvin's power amps and mixers are made in the USA, and will provide excellent sound and performance for years. High current components & FR4 fire retardant circuit card
