Description
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 differentiated 4-ch DAC architecture.
The 1-bit DAC circuit is a resistor network composed of 128 pcs (4 x32) high 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 be converted to a 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 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 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 the portable desktop amplifier or home audio system and use it as a miniature 1-bit DAC.
Discrete Volume Control
Discrete Resistor Network DAC circuit is very demanding on incoming data integrity, we recommend users keep the digital volume of mobile phones at full output to safeguard the quality of the audio digital signal. When off-the-shelf analogue volume options cannot meet the high precision, low noise, low power consumption requirement of RU7, we developed our 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
Outstanding Digital Audio Capability with User Selectable All-to-DSD & Low Power Consumption
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.
Discrete resistor network is a low-power DAC circuit when compared to other highly integrated DAC chipsets, minimises power drain from mobile sources. The redesigned amplification circuit increases output power dramatically while maintaining 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
Dual PCB to Minimise Interference To minimize interference, RU6 circuitry
RU7 is split into TWO 6-layer PCBs, with digital and analogue circuits installed in separate boards. Safeguard signal integrity and make sure the noise from the reference clock and DSP will not bleed into the amplification circuit.
Soft and tender handmade magnetic leather case Custom made for RU7, precise cutout offers tight-fit protection and elegant presentation Two circular metal plates with adhesive tape pad are included.
