RU7 Dongle DAC
Fully Balanced Resistor Networks Discrete 1-Bit DAC for DSD Format
A new benchmark for ultra-portable An Irresistible Upgrade 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 Parallel 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 @3252 4.4mm BAL, 400mW @3252
Shared Line Out Conviently 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 SE, 160mW @3282 4.4mm BAL, 400mW @322 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
Discrete Volume Control
Discrete Resistor Network DAC circuit is very demanding on incoming data integrity, we recommend users to keep the digital volume of mobile phone at full output to safeguard the quality of audio digital signal. When off-the-shelf analog volume options cannot meet high precision, low noise, low power consumption requirement of RU7, we developed our 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
IM users:
Segment 1: 1-49
Segment 2: 50-79
Segment 3: 80-100
Dual PCB to Minimise Interference To minimize interference, RU6 circuitry
is splited into TWO 6-layers PCB, with digital and analog circuit installed in seperate boards. Safeguard signal integrity, make sure the noise from reference clock and DSP will not bleed into amplification circuit.
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 format and go through high precision signal enhancement. All digital audio signal will convert to designated DSD format (DSD64/DSD128/DSD256) before feeding to the discrete 1-bit DAC circuit.
Low Power Consumption Compatible with Common Platforms
Discrete resisotr network is a low-power DAC circuit when compare to other highly integrated DAC chipset, minimise power drain from mobile source. Redesigned amplification circuit increase output power dramatically while maintains the overall power drain at 100-110mA 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
Bundled Protective Case, A Compact and Nimble Powerhouse
Soft and tender handmade magnetic leather case Custom make for RU7, precise cutout offers tight-fit protection and elegant presentation Two circular metal plate with adhesive tape pad are included.
