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 differentiated 4-ch DAC architecture The 1-Bit DAC circuit is a resistor network composed of 128 pcs (4 x 32) high-precision Thin Film Resistors, this closely resembles to the discrete DAC of N7 DAP The output of the resistor network will go through a 3-level active LPF and then be converted to a single-ended signal for volume adjustment. High Power Parallel Phone Amplifier 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 is carefully selected to retain as much detail and dynamic of the 1-Bit DAC with minimum noise and distortion. Enable you to connect the RU7 to a portable/desktop amplifier or home audio system and used it as a miniature 1-Bit DAC Discrete Volume Control Discrete Resistor Network DAC circuit is very demanding on incoming data integrity, Cayin recommends users to keep the digital volume of their mobile phone at full output to safeguard the quality of the audio digital signal. When off-the-shelf analogue volume options could not meet the high-precision, low noise, low power consumption requirement of RU7, Cayin developed their own discrete resistor network volume control 100 steps volume control through 3 segments of resistors and switching relays, offer precise control over a wide volume range, satisfy even the need of most sensitive IEM users Outstanding Digital Audio Capability with User Selectable All-to-DSD RU7 supports PCM up to 384kHz and native DSD from DSD64 to DSD256 Its Audio Bridge will receive different audio formats and go through high-precision signal enhancement All digital audio signals will convert to the designated DSD format (DSD64/DSD128/DSD256) before feeding to the discrete 1-BIT DAC circuit. Dual PCB to Minimise Interference To minimize interference, RU7 circuitry is split into TWO 6-layerrs PCB, with digital and analogue circuit installed in separate boards. Safeguard signal integrity makes sure the noise from the reference clock and DSP will not bleed into the amplification circuit. Low Power Consumption, Compatible with Common Platforms The discrete resistor network is a low-power DAC circuit when compared to other highly integrated DAC chipsets, with minimised power drain from a mobile source. Redesigned amplification circuit increase output power dramatically while maintaining the overall power drain at 100-110 mA Low power consumption allows RU7 compatibles with the following digital audio sources: Android-based mobile devices iOS and iPad OS mobile devices macOS computers Window 7/8/8.1/10 computers Digital Audio Players with USB Audio output
