Technology
 Class D
Class D is the most advanced technology, is suitable for high power amplifier, accurate sampling signal through Class D power module, amplifying the output signal, compared with other standard power amplifier products, D series to achieve higher efficiency, better sound, Class D power amplifier with low distortion and high power amplifier
 R-SMPS Switch type appliances
Because of the design of the distribution network is not in place and unstable generator, resulting in some sound reinforcement applications, the power supply voltage fluctuation is not stable, D series power amplifier with voltage switching power supply voltage, regardless of type, it can guarantee the stability of the output signal level of the power supply, even in the poor state of the situation R-SMPS, is the best guarantee to provide sound
 HS CMRP Balanced Input
Only the best quality of the input signal, the output signal of the amplifier in order to get the best, in between have the independent power supply system equipment when the analog signal transmission cable will produce additional "hum" sound on the signal line, "buzz" sound, radio frequency interference, D realizes the CMRR design of high sensitivity, stop even the slightest signal interference, bring the ultimate sound to the audience
 SPPT
As of CS Audio two channel SMPS flagship series power amplifier D series installed only in the market is considered the most durable quality audio audio special electronic element, electronic accessories any sound D series amplifiers either including operational amplifier, power capacitor, power module or bipolar crystal, are used for electronic audio the best of the best components, making audio requirements
