Discrete Volume Control
R-2R DAC circuit is very demanding on incoming data integrity,digital volume
of mobile phone will damage sound quality badly.
When off - the - shelf volume options cannot meet high precision, low noise,
low power consumption requirements of RU6, we developed our own
discrete resistor array volume control.
0-99 steps volume control through 9 segments of resistors and switching relays*,
meet all the RU6 requirements and transparant to maintain the natural sound
signature of R-2R DAC.
