Why Explorer DAC?
Explorer DAC
Explorer consists of two separate chassis
High precision audio decoding core
• pure R-2R+DSD architecture: the true balanced 24 bit R-2R+6-bit DSD (32-stage finite impulse response filter) ensures accurate restoration of audio details.
• dual low-phase noise crystal oscillator (45.1548mhz, 49.152mhz): precise clock synchronization to reduce time base error.
• 0.005% high precision paired low-temperature drift resistance: reduce conversion error, lower the bottom noise to 2 μ V (1/10 of traditional DAC), and the dynamic range exceeds 126dB.
• multiple low noise LDO power supply voltage stabilization: stable power supply, reduce interference.
HD display
3-inch monochrome LED screen
clear display of working status.
Multifunction knob
high performance front-end DAC integrated design, knob can directly adjust the volume, without additional front-end equipment, simplifying the audio system.
Custom interface
customize the data transmission interface, optimize signal transmission, and provide power for explorer-d to reduce external interference.
High-Precision R-2R+ DSD Architecture
The R-2R provides the natural harmonic structure of PCM, and the DSD path retains the original modulation characteristics, avoiding the noise shaping distortion of the traditional delta sigma architecture. Typical examples are the "dual native" processing scheme adopted by some high-end decoders.
Explorer-D(digital signal input unit)
As a key component of the first split decoder scheme, it focuses on digital signal reception and transmission.
• rich input interfaces, compatible with various sound source devices:
• USB (up to dsd1024, pcm1.536m)
• coax (coaxial)
• AES
• opt (optical fiber)
• I ² s
The customized data line can not only transmit high-purity digital signals, but also provide power for explorer-d, making explorer-d structure more concise, and effectively reducing the interference of digital circuits to audio signals.
Customized data cable
All aluminum alloy fuselage
proprietary FPGA algorithm processing, plus adaptive FIFO buffering and clock shaping technology: realize ultra-low delay data transmission, reduce clock jitter, ensure signal integrity, and optimize sound quality.
All aluminum alloy body with integrated shielding design reduces external interference.
Equipped with an exquisite remote control to provide convenient control experience
The first split decoder defines a new standard for high-end hifi audio
As the first hifi audio decoder of napoulern brand, explorer DAC reconstructs the system topology of traditional R-2R DAC through innovative digital analog split architecture. The design uses the isolation cabin shielding technology to physically divide the digital signal processing unit containing high-frequency switching noise and the analog conversion channel with high-precision R-2R resistance network as the core, so as to achieve the performance breakthrough of ultra wide dynamic range and signal-to-noise ratio (≥ 126dB).
• Explorer-d (digital signal unit)
Be responsible for receiving and processing digital signals to ensure stable and accurate signal transmission.
• Explorer Ontology
Carry out digital to analog conversion and provide high-quality analog signal output.
• remotely adjust the volume to easily control the front output.
• input source switching, supporting USB, coaxial AES、 Optical fiber, I ² s and other input modes.
• I ² s interface pin switching to adapt to more devices.
