Fully Balanced Resistor Networks Discrete 1-Bit DAC for DSD Format
Purposively designed micro-miniaturized 1-bit DAC circuit from discrete components convert digital signal to analogue signal through a fully differentiate 4-ch DAC architecture
The 1-Bit DAC circuit is a resistor network composed of 128 pcs (4 x32) high precision thin Film Resistors, this is closely resemble to the discrete DAC of our N7 DAP
The output of the resistor network will go through a 3-level active LPF and then converted to single-ended signal for volume adjustment.
High Power Paraller Phone Amplifiers
Dual amplifiers in parallel, providing 4-CH high power balanced Driven output
The second phone amplifier is a parallel unity gain inverting phase amplifier
An impressive upgrade in
phone output power :
3.5mm SE, 160mW @32Ω
4.4mm BAL, 400mW @32Ω
Shared Line Out Conveniently Connected
The shared line out function will configure the 3.5mm or 4.4mm phone output into fixed voltage output (bypassing volume control): 3.5mm Single-ended, 1.2Vrms 4.4mm Balanced, 2.4Vrms
The line out voltage are carefully selected to retain as much details and dynamic of the 1-Bit DAC with minimum noise and distortion.
Enable you to connect the RU7 to portable/desktop amplifier or home audio system and used it as an miniature 1-Bit DAC.
