Message from the Founder
Dear Fellow Music Lover:
Thank you for your purchase of a HIFIMAN product. We take great pride in
offering audio products that provide best-in-class performance and value.
Though it seems like only yesterday when I started HIFIMAN as a passionate
audiophile, we are in our second decade in business and eagerly look forward
to an exciting future. The company is rapidly growing, and the HIFIMAN brand
has become one of the most respected in the industry.
Even with our success, the one thing that has not changed is my passion for
music and creating products that help recreate that live experience. Now, I am
joined by many others in the company who share my passion and in turn, we
humbly share that with you.
Thank you again for your purchase. I hope you will find this guide useful in
learning about your product which will help you enjoy countless hours of
listening pleasure.
Happy listening,
Fang
Dr. Fang Bian, Founder and CEO
HIFIMAN DAC Development History
For over 20 years, HIFIMAN is famous for its audiophile headphones and digital
audio players. (DAP) HIFIMAN players traditionally feature the R2R DAC archi-
tecture, which is composed of an array of resistors. Like magic, it transforms
a series of l’s and 0’s into spellbinding music.
The resolution of this architecture is superb, but the accuracy of the
resistance matrix calibration creates difficulties that lead to high costs and
excessive energy consumption. Thus, the market typically employs the less
expensive Sigma-Delta DAC, which measures well but due to the many
intermediate links, the overall listening experience is not on the same level
as R2R.
As a company that is committed to satisfying the demands of discerning listen-
ers through advanced, yet cost-effective designs, HIFIMAN is proud to present
its latest achievement: the HYMALAYA DAC. The result of five years of focused
product development, the HYMALAYA DAC retains the R2R architecture, but with a
unique algorithm on an FPGA Chip that reduces electrical between the chip and
peripheral components. Signal-to-noise ratio, total harmonic distortion and
energy consumption are at their most efficient and cost-effective.
Whether paired with the HIFIMAN RE2000 Pro or other earphones, DAPs with the
HYMALAYA DAC architecture makes it easy to enjoy hi-res audio via the USB-C
output of an ordinary mobile phone, making it a high-fidelity source that can
compete with nearly any standalone DAP.
The Soul of HM800 – HYMALAYA DAC
HIFIMAN Independent Research and Development, R2R Architecture DAC
HYMALAYA is a discrete R2R DAC (digital-to-analog) module that is based on the
FPGA algorithm.
The combinations of its low audio frequency range, out-of-band noise, and low
energy consumption make it a perfect match for high-perfor-mance audio
equipment. The HYMALAYA DAC module supports the standard PCM music signal
transmitted by the most common IIS (Integrated Interface of Sound) audio
interface, with a maximum resolu-tion of 24Bit.
Ultra Low Energy Consumption
The HYMALAYA R2R DAC in the HM800 is famotis for its low power consumption.
At the same time due to the characteristidt of its voltage output, it only
needs a simple amplifying circuit to achieve its excellent sonic output. Low
energy consumptiptv ensures that the thermal, or Johnson noise is extremely
low.
Concept-based NOS (None Over-Sampling) Filter Design
The oversarnpling titter is Widely usedm audio DACs to alleviate weak signal
aliasing and to push the quantization noise to the ultrasonic frequency band
so that it can be cut off by the analog filter. However, it sometimes pushes
the weak signals to the ultrasonic frequency band, cutting them out
altogether.
The HM800’s HYMALAYA DAC is designed to draw on the benefits while eliminating
the negative effects. With the HYMALAYA DAC, the best possible performance is
achieved while preserving the most minute details of every recording.
Lightweight and convenient
The body of the HM800, which supports plug-and-play devices, is barely larger than a coin.
Pure Output
Maximum output is 40mW, making it easy to match the sonic output of more
expensive R2R devices.
The Cable
The HM800 is packaged with several well-constructed high-end cables so that
customers can use the DAC/Amp with their favorite earphones.
Included in the package:
- • Compatibility depends upon the specific design of your earphone.
- IMPORTANT: Always pay attention to the direction of the pin connector when connecting the HM800 to earphones. The connector will either face up or down, depending upon the input.
