Congratulations to you for being the owner of Questyle Audio Super Hub SHB2.
Super Hub SHB2 together with Questyle Audio Digital Audio Player OP2R or update
Digital Audio Players will build a Super Source System, resulting in Questyle taking a
huge leap towards defining the future. You will enjoy high-quality music in a simple
and easy way by virtue of Questyle’s state-of -the-art technologies.
The more complicated the world is, the more concise we are. Simply plug in the
Super Source System and press the play button, then beautiful music will flow
around you.
Super Hub SHB2 has a full range of input and output interfaces, supporting USB,
Optical, S/PDIF and AES digital signals, as well as RCA analog input, balanced and
unbalanced analog outputs. In addition, it supports professional interfaces of AES
and XLR that are used in recording studios. It is user switchable between Studio and
Standard mode. In the Studio mode, the power level will change from 14dBu up to
20dBu instantly, matching it with studio-level professional equipment.
Super Hub SHB2 is easy to use. It can match with various audio equipment and bring
you an exceptional listening experience. With connecting the SHB2 to your PC via a
USB cable, switch the player to Memory mode and it will download the recording files
automatically and sync to the player, which makes it convenient for you to take the
recordings along and listen to them at any time. When streaming Tidal, QuBuzz or
Spotify, your only need is to connect the SHB2 to your PC or a server via USB,
Optical or S/PDIF, switch it to the DAC mode and it will work as a DAC, then you will
get much better sound quality from your PC or the server
The design style of Super Hub SHB2 originates from Questyle’s iF Design Award
winner, which is impressive for its firm structure, smooth faces and unbroken lines
flowing around the perimeter. Along with Foxconn’s high precision machining
technique (0.02mm), the whole system exudes its charm of Quest and Style.

Mechanical vibration will affect audio signal processing and sound listening. But
Super Hub SHB2 will avoid resonance by its special structure and material. The
player docking of the SHB2 is made of special silicone and pure aluminum, plus the
stable feet, helping to reduce resonance to a lowest level.
Super Hub SHB2 adopts Questyle’s core patented technologies of Current Mode
Amplification and True DSD. As the “engine” of an audio system, the Current Mode
Amplifier is designed with an all discrete circuit and pure Class A operation that
allows the SHB2 to have outstanding performance and provide users with an experi-
ence of being there listening to the original sound. With the True DSD technology and
the DAC chip AK4490, the SHB2 processes DSD signals without any PCM convert-
ing, providing the original DSD signal processing.
The pre-amplifier of Super Hub SHB2 has excellent performance because of the
customized Current Mode Amplification modules CC630 and CA630. The SHB2’s
analog output can be set to Fixed or Adjustable. It’s very easy for you to build a
lossless audio system since the SHB2 has a full range of input and output interfaces,
plus a remote control. It is user-friendly to match with Hi-Fi amplifiers or active speakers.
There are two versions of Super Hub SHB2, the first is SHB2 (standard version), the
other being SHB2 Master. The SHB2 Master has a “MASTER” laser marking, and it
features the ROGERS Ceramic PCB and selected components to ensure the
ultimate performance on sound quality and specifications.

USB/DAC switch: switch it to have the SHB2 work as a DAC and the DAC
mode indicator is on, then the SHB2 will play music files in your PC via USB. When
the DAC mode indicator is off, your PC will connect to the player, recognize the
player as a USB flash disk and import music files from your PC

·Go to page n to see “5G Wireless Pairing”.
Getting System Started
When you power on the Super Hub SHB2, it starts with the Power indicator flashing
quickly and the OLED display showing a startup picture. It completes the startup
and starts to work when the Power indicator stays light on and the OLED display
shows the volume, sample rate and input mode.
How to pair Super Hub SHB2 with 5G wireless receiver
First, power on Super Hub SHB2 and the 5G wireless receiver (CMA Twelve) ,
make sure both of their 5G Wireless mode switches are on, otherwise they can’t be
paired.
Second, press the 5G Wireless Pairing button on the SHB2 and the receiver, then
the 5G Wireless mode indicator will flash quickly to show that the SHB2 is pairing,
and it will stay light on to show that the SHB2 and the receiver are successfully
paired. If the pairing isn’t done within 30 seconds, the SHB2 will exit the pairing and
the 5G Wireless mode indicator will flash slowly.
If the 5G Wireless Pairing fails, please repeat the pairing steps above. If the SHB2
can’t pair with the receiver, you have to contact your dealer or the After-Sales
Support.
5G Wireless Pairing
Before using the 5GHz Wireless Transmission, you need to pair Super Hub SHB2
with the 5G wireless receiver.

1) Operation System
Super Hub SHB2’s driver and hardware support Win XP / Vista / Win7 / Win8 /
Win8.1/ Win10. For Apple Mac OS, later versions than the 10.5.7 are well matched
without installing any driver.
2) Media Player
Super Hub SHB2 is not limited to any special media player. Any PC compatible
player (including video players) is well matched.
3) File Format
File format is up to the media player on your PC. Super Hub SHB2 can decode any
file format that the media player supports.
4) Requirements for PC Configuration
At least one USB port is required. An acceptable USB2.0 high-speed cable of type
A-to-B plug. We suggest using the high-quality USB cable to ensure the stability
andreliability of data transmission and guarantee the best performance of
Super Hub SHB2.
Your Super Hub SHB2 can be recognized by PC after installing the Super Hub
SHB2
Driver on Windows OS. We take Win7 64bit OS for an example to show the
Driver installation.
1) Connect your
Super Hub SHB2 to its power supply and switch it on;
2) Connect your Super Hub SHB2 to PC with a USB cable;
3) Put the provided Super Hub SHB2 Driver disc into your PC and open the folder
labeled “
Super Hub SHB2 Driver/For Windows 7, 8, 8.1 and 10/” and then
double click “Setup.exe”.
PC System Requirements Install Super Hub SHB2 Driver on Windows OS

16 17
Click “Install” (Default install location is C drive) Installation is completed, click “Next”
5) Restart your PC and the CMA Twelve Driver is finished installation;
6) Installation on Win XP, Vista is similar to the above.
Click “Finish” to exit the installation
Installation will take 3 or 5 minutes

Core Audio Stream has formats of ASIO, KS and WASAPI, all of which can be
supported perfectly by CMA Twelve. Besides, Super Hub SHB2 supports DSD
format.
According to general audio processing procedures of PC, all the sound from
applications and systems is processed by SRC, going through the lengthy system
processing and hardware layer transmission, and then output to the external
device. The output data are totally different after all those procedures. To output the
pure, original and “bit-perfect” data, we must open a high-speed and dedicated
channel for audio device, which is the core audio stream technology.
Super Hub SHB2 supports ASIO and KS on Win XP systems, and supports ASIO
and WASAPI on Vista, Win7, Win8, Win10 systems. For example, when you
enable WASAPI + Exclusive Mode between CMA Twelve and player software (like
JRiver), you can't control the volume through system controller, the sound from the
system or any other application will not be heard at the Super Hub SHB2 output,
which is because the system has opened the Core Audio Stream channel for CMA
Twelve and the audio data directly get to the DAC of Super Hub SHB2 with
high-speed.
We recommend using Jriver Media Center 20 for getting the best performance.
JRiver Media Center is a fully functional media management and playback
software. It can manage your music in groups and can stream music from the
Internet. It also can be used for MP3 or DVD burning. JRiver can support kinds of
audio files including MP3, MusicEx, WAV, OGG, RealAudio, RealVideo, AVI, Quick-
Time etc.
Let’s take JRiver Media Center player 20 on Win7 32bit OS for an example to
explain how to setup WASAPI.

Nothing is better than the true. The True DSD technology is one of the core patent-
ed technologies of Questyle Audio. It processes DSD signals without any PCM
converting and provides True DSD, which is fundamentally different from DoP and
Native DSD.
When the system processes DSD signals, hardware mode switches to the True
DSD channel. In this case, options for digital filter and digital volume control fail,
strictly following the process of SACD playback.
