GUSTARD R26 Discrete R2R DAC (Used-Like new)

【Discrete R2R DAC】R-2R ladder DAC converts the digital signal to analog signal by switching resistor's array.

【1Bit DAC Native】1 Bit DAC, supports DSD 512 ( via USB ) and DSD 1024( via IIS ) .The DSD stream is decoded by the independent 1 Bit DAC without DSD to PCM converting.

【Clock Synthesis】DAC-R26 adopts ultra-low noise clock synthesizer K2 clock . Provide an accurate clock from the local oscillator or external clock input. The interference from the input source clock is avoided.

【LPF Of DAC-R26】The discrete circuits of the DAC-R26 control every detail of sound and performance. LPF is specifically designed for the D/A converter using discrete devices.

【XMOS XU216】DAC-R26 using 2nd XMOS XU216, supports up to PCM768 & DSD512.

Features:

Discrete R2R DAC: R-2R ladder DAC converts the digital signal to analog signal by switching resistors' array, it provides a more natural sound. However, this architecture needs precision resistors and deep development to archieve fine performance.

Native 1Bit DAC:support DSD 512 (via USB) and DSD 1024 (via IIS). The DSD streamdecoded by the independent 1 bit convertor without DSD to PCM converting.*Volume is fixed under this mode.

CPLD: Complex Programmable Logic Device:Signal routing; Clock management; 2nd order PLL; DOP decoding; Depop for PCM&DSD.

Clock synthesization: Replace the input signal' s clock with precision oscillators (local or external). Interference from the input source' s clock is avoided. Function off: IIs, AES, COAX, OPT, BT; PCM NOS, 1 Bit Function on: USB & LAN K2, ultra-low noise clock synthesizer: provides precision clock from local oscillators or external clock in.

LPF is specifically designed for the D/A converter using discrete devices. Final parameters of the circuit are adjusted with subjective listening. Different from IC s, discrete circuits provide the possibilities to control every detail in sound and performance. But the parasitic effects introduced huge challenges to development experience and device' s quality.
