看到Metrum官方对于Adagio和PAVANE区别的说明:
• As volume is controlled by changing the reference voltage of the dacs, max ref voltage is increased 3 times. This approach created a noise floor of - 155 dB ,extreme linearity and very low distortion!
• Instead of using our DAC ONE module as used in our Pavane, for the Adagio we used our DAC TWO. DAC TWO is using two R2R ladders on the inside which means that the Adagio is using 16 ladder dacs instead of 8 ladder dacs as used in the Pavane.
• The Adagio is running on double voltages compared to the Pavane.
• The Pavane is using 15 VA transformers for each channel, the Adagio is using 30VA for each channel.
• By using DAC TWO modules ( in fact every module contains a FPGA + two R2R ladders) there is no need to use the external FPGA anymore as used in the Pavane. This location on the digital input board can be used for future options
关键点:Adagio是 16 ladder dacs Pavane是8 ladder dacs
PAVANE供电是15VA的牛每信道,Adagio是30VA |
