Why Explorer DAC?
Explorer consists of two separate chassis
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)
I²s
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
Explorer DAC
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)
High precision audio decoding core
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
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
EXPLORER - D
Remotely adjust the volume to easily control the front output.
Input source switching , supporting USB , coaxial AES、 Optical fiber, I²s and other input modes.
I² s interface pin switching to adapt to more devices.
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
