Dual Power Supplies Design
ln order to eliminate interference and noise between the system circuit and the audio circuit, and to enhance sound purity, separate designs are employed for the power supply of the system and the audio circuit. The linear power supply is composed of a multi-winding toroidal transformer, specifically designed to match the characteristics of analogue audio circuits. The high-quality switching power supply is tailored for the system circuit. It significantly reduces ripple and magnetic leakage interference, providing strong support for high-quality audio processing. Furthermore, it incorporates a patented smart switching technology for the linear power supply voltage input, enabling compatibility with voltages worldwide without flipping switches.
3rd Generation XMOS 316 Audio Interface
With 3rd generation XMOS 316 audio processor, DMP-A8 has faster speed and higher USB bandwidth ensuring the lossless transmission of high-definition audio data. USB ports supports up to DSD512 Native and PCM768@32bit. The optical and Coaxial ports support DSD 64 (DoP), PCM192@24Bit.
AK4499EX / AK4191 EQ Digital-analogue Separation DAC Solution
VELVET SOUND is the brand that imparts "sonic philosophy" to the new generation of AKM audio products. The pinnacle flagship series, VELVET SOUND | VERITA, offers forward-thinking products with world-class performance. Rooted in the concept of “perfect re-creation of the original sound," it is dedicated to providing continuous enhancement of audio technology, presenting the most authentic sound, and offering listeners an immersive acoustic experience.
Dual High-precision Clocks
There are 2 ultra-low phase noise femtosecond high-precision clocks for audio decoding circuit (45.1584MHz and 49.152MHz), which correspond to the decoding of 44.1KHz and 48KHz multiplied sampling rates respectively. This effectively suppresses Jitter, ensuring highly accurate conversion and decoding of digital-to-analogue audio signals, providing ultra-high dynamic range and resolution for analogue audio output and reproduces the real sound details from music studio.
Fully Balanced Analogue Preamplifier Circuit
The DMP-A8 is equipped with a high-performance fully balanced preamplifier function, supporting XLR/RCA analogue inputs. It also features a +10dB analogue gain and, when combined with the R2R analogue volume control network, ensures ultra-low noise and distortion for the output.
R2R Volume Control Circuit
A fully balanced analogue volume adjustment network composed of precision resistors and relays achieves accurate volume control, effectively suppressing distortion and noise in the analogue signal. It also features volume protection, automatically reducing excessive volume to the designated safe level during startup or input interface switching. The incorporation of R2R analogue volume control ensures that the DAC can operate at its optimal state continuously.
HDMI-IIS Output
DMP-A8 outfits IIS output, which can connect to DACs with IIS input. The mute levels of different DACs’ IIS signals vary, MUTE PIN can be switched by settings. Supporting PCM 768K, DSD512 with the highest sampling rate.
HDMI ARC
The DMP-A8, equipped with HDMI ARC (Audio Return Channel) input, can be connected to display devices such as TVs and projectors that have HDMI ARC capability. This allows the separation and transfer of audio signals from the HDMI signal to the DMP-A8, providing the TV with a higher quality sound.
Handpicked Audio Components
Sound quality of DMP-A8 analogue output is monitor-level. The primary elements of the audio circuit are excellent, including WIMA capacitors from Germany, NICHCON dedicated audio capacitors, Murata chip capacitor and Omron relays from Japan, TI Audio Operational Amplifiers from the USA etc. The goal is to provide more authentic and pure sound performance.
Professional Tuning and Outstanding Analogue Audio Performance
In order to faithfully reproduce a rich and critical audio quality, we are constantly advancing our technology. Extremely low distortion and noise create a quieter background, making everything clearer.
- -120dB THD+N
- 128dB SNR
- 128dB Dynamic range
*Note: The DSP module supports up to PCM 192kHz. PCM and DSD formats with a sampling rate higher than this will be Bypass output.
DSP is only for internal player, network streaming, optical input, coaxial input, USB input, Bluetooth input, and ARC input, and takes effect when producing analogue outputs.
Flexible and Powerful DSP functionality
DMP-A8 incorporates a robust DSP processor that supports DSP volume control, PEQ, FIR Filter, HPF/LPF, Loudness enhancement, Compressor, and Delay.
