Hiby RS6 - R2R high-end DAP

Full of musicality, vibrant and natural, the R2R-based amplifier stage brings the music to life and the performers on stage to an immersive experience.

Switchable oversampling / NOS

NOS mode bypasses oversampling and antialiasing, reacts instantly to transients and stairsteps, and converts the signal to analog as raw and direct as possible.Oversampling mode removes aliasing artifacts, enables all features of the Darwin architecture, and allows customization of the sound signature for different headphones;

DSD bypass function



With separate LPFs for PCM and DSD, native DSD decoding is on an R2R system no longer a contradiction The DSD-specific LPF effectively reduces the RF noise caused by the delta-sigma modulation process, thus optimizing DSD audio reproduction.

Headphone-Specific Tuning



We have already cooperated with 10 professional HiFi brands in and outside of China, and the sound tuning Experts from each brand are brought to match the various hardware parameters of the Darwin architecture to the characteristics of their earbuds to create bespoke tunings for each brand, all available with a touch of the screen; more will follow...

MQA 16x Unfolding



The high processing power of the SoC enables an unprecedented 16x unfolding of MQA data and thus the reproduction of the Original master bands from ever smaller source files!

MQA is an award-winning technology that captures and reproduces the sound of the original studio master in a file small enough to be streamed and downloaded. HiBy works with MQA to bring the true original sound quality to the listeners.

Mature and powerful SoC



Using the mature and powerful Snapdragon 660, coupled with fast LPDDR4 RAM and eMMC storage, resulting in demanding multithreaded calculations (audio or other) can be performed in record time.

14nm LPP process, 8-core Kryo-260 architecture, 2.2GHz, Adreno 512 GPU, 4GB LPDDR4 RAM, 64GB storage and Micro SD slot


Great gain scheme



To the whole To top it off, a 1x OPA1642 and 2x OPA1612 discrete current amplification scheme has been implemented, providing ample current to the output stage to achieve excellent dynamic and transient response. This is then coupled to 4 top-of-the-line OPA1622 op amps to give 8 independent headphone amplification channels connected 2x2 in parallel; each channel is a combination of voltage and current gain stages. This is all controlled by a professional NJW1195A digital volume controller, ensuring optimal control and ideal circuit dynamics at all times.

HiBy OS, the eternal god of audio!



The HiBy OS is the system architecture developed by HiBy for HiFi audio , optimized from the ground up for audio processing. Now adapted for Android 9 OS, it opens the system for free installation of any Android app and also supports advanced audio features like USB audio input and output, wireless audio input and output, and system-wide audio effects.

System-wide Direct Transport Architecture now also with USB



The Direct Transport Architecture has always been known for the originally mandatory sample rate conversion of Android for the integrated headphone output.Now DTA can also bypass sample rate conversion for third-party applications even if they use USB audio, achieving bit-perfect output from almost any application to anywhere

HiByLink support



With the practical HiByLink function, you can control your RS6 via the HiByMusic app on your smartphone and thus playback , volume control, playlist management, etc. remotely!

A wireless world



Supports both Bluetooth audio reception (to wired headphones or USB output) and Bluetooth -Audio transmission (to Bluetooth headphones) according to the Bluetooth 5 standard and a variety of Bluetooth codecs such as UAT, LDAC, aptX, aptX HD, AAC, SBC, etc. Ultra stable 2.4 GHz and 5 GHz WiFi for reliable, ubiquitous online music access. Support DLNA / AirPlay / WiFi audio transmission.

Playtime



With its 4500mAh high-capacity battery, the RS6 is capable of up to 8.5 hours of continuous playtime and 25 days standby time. Supports Quick Charge QC3.0 for a charging power of up to 18 W.
