Discrete 24-Bit R-2R Ladder Resistor
Network Explained
The basic idea of R-2R ladder is a matched pair of two resistors, the first is “ R ”
and the other is “ 2R ” which has twice the value of R.
To achieve 24bit R-2R decoding, we need 48 pieces of resistors ( 23xR and 25x2R )
for one channel, or 96 pieces of high precision resistors for stereo.
R-2R is famous for its natural and realistic sound signature, it’ll offer a very different
experience to music lovers.
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 transparent to maintain the natural sound
signature of R-2R DAC.
Intuitive and Versatile
Hardware volume buttons for convenient control, doubled as menu selection
when enter Mode settings.
1” OLED screen displays playback information with good visibility.
3.5mm and 4.4mm phone out to fit your earphone collection.
Ultimate Dual Main Boards Layout
To minimize interference, RU6 circuitry is spited into TWO 6-layers PCB, with digital
and analog circuit installed in separate boards.
Safeguard signal integrity, make sure the noise from reference clock and DSP will
not bleed intro amplification circuit.
Low Power Consumption Highly Compatible
Discrete R-2R is a low-power DAC circuit when compare to other highly integrated DAC
shipset, minimized power drain from mobile source.
USB Audio with shielded interconnect USB-C interconnect, compatible with wide range of
mobile, consumer electronics and computers.
High Resolution and High Fidelity
High-end digital audio capability.
• PCM: supports up to 384kHz
• DSD: supports DSD64/128/256
Choice of High/Low gain to enhance performance with different IEM or portable
friendly headphones.
