Introduction
Thank you for selecting Questyle Audio T2 Transmitter of 5GHz Hi-end Wireless Audio
System.
The worldwide first Hi-end 5G wireless audio system was born in Questyle Audio. It provides
Hi-end sound performance with easiest wireless operation. The system is made up of wireless
Transmitter and Wireless Receiver (built-in DAC and Amplifier).
The current 2.4GHz wireless HiFi system set people free from the hateful cable decoration ,
brings an innovation on audio field. But the shortage is that it’s always be interferenced,
interrupted or delayed. Questyle 5GHz Wireless Series transmit signal in 5.8GHz frequency,
totally get rid of the 2.4GHz frequency interference, achieve more stable transmission.
T2 Transmitter support digital input with USB, Coaxial and optical. It can also receive analogue
signal through RCA input, with built-in ADC to convert to digital signal for transmission. It’s
easy operate, can work automatically after power on. It can wireless transmit signal in
24bit/48KHz, with the FIFO and digital PLL technology, reduce Jitter to undetectable level.

Quick setup
1. Power on T2 Transmitter and R100/R200 Wireless Amplifier
1) T2: Use its adapter to link its DC port with AV power supply.
2) R100/R200: Plug its power cord, and turn on the switch.
3) Pair T2 with R100 or R200.
2. Pairing T2 Transmitter with R100/R200 Wireless Amplifier
1) T2: Long press the “INPUT” button (on front panel) for over 3 seconds, until 4 LED
indicators starts flashing (flash lasts for 60 seconds). It means T2 is ready for pairing.
Then release the “INPUT” button.
2) R100/R200: There is a “PAIRING” button at R100/R200 bottom chassis. When T2 is
ready for pairing, pin the “PARING” button until its front panel LED indicator stop flashing.
If it keeps flashing, it means not successfully paired, please pin the button again.
3) When T2 is in “Paring” status, user can continuously pair it with more Receivers.
4) AT2 Transmitter max pair 8pcs Receivers (R100 /R200 can be mixed, total 8pcs).
5) After pairing, T2 is ready to be linked to audio source.
3. T2 setup
1) T2 can be linked to PC by USB input, CD/DVD player by SPDIF or TOSLINK, Analog
signal by Analog input.
2) Press the front panel “INPUT” button, to select “USB”, “TOSLINK”, “SPDIF”, “ANALOG”
according to the real input mode.
3) Then the whole system is successfully setup.

CAS system
(If you don't use the USB input function of T2, you won’t need the following settings)
1) Operation System
T2 Driver and hardware system support Win XP, Vista, Win 7 of 32Bit/64Bit, Win 8 of
32Bit/64Bit operating systems. For Apple Mac OS, later versions than the 10.5.7 are well
matched, doesn’t need to install driver.
2) Player
T2 is not limited to any special media player, any PC compatible player is well matched. In
Windows system, we recommend JRiver Media Center for good sound performance.
3) Music Format
Music format is up to the media player. T2 doesn’t require any special music format, it can
decode any music format as long as the media player support it. For example, JRiver Media
Player can wonderfully play formats likeAPE, FLAC, WAV, AIFF and MP3, etc.
4) The dedicated driver of T2
T2 can support Microsoft operating systems of Win XP, Vista, Win7 32bit/64bit, Win8
32bit/64bit. At present, all the operating systems of Microsoft neither support the audio driver
of 480Mbps USB2.0, nor support the output of 24Bit/192K USB audio data. The commonly
used Microsoft driver of USB audio device is sort of USB 2.0 full-speed, whose maximum
transmission rate is 12Mbps, it supports at most 24Bit/96K audio data. Some USB audio DAC
can support playing the music of 192K sample rate, but it processes 192K audio data just
under the condition of installing a universal driver called "Thesycon" and with many complex
settings, which is unavoidable to meet problems of compatibility and stability, and can’t ensure
the best performance of the whole system. However, with the different hardware system, the
dedicated driver of T2 can avoid those problems fundamentally.
5) PC Configuration Requirements
Operating system of Win XP (SP2 or SP3), Vista, Win7 32bit/ 64bit, Win 8 32bit/64bit or later
versions of the 10.5.7 Mac operating system. At least one USB port is required.
An acceptable USB2.0 high-speed cable of type A plug to type B plug. User is suggested to
take high-quality USB cable for stable data transmission and guarantee the best performance,.
6) Other Requirement
Communication between T2 and PC is real-time and it has some requirements for PC
hardware and software platforms. If the platform is bad or the PC is very busy, it will cause T2
to work unstably as well as some other abnormal statuses. In such cases, try to run the dpclat.
exe(http://www.thesycon.de/deu/latency_check.shtml) to check whether the Ethernet,
Wireless LAN or other equipments have affected the working of T2.

Install the Dedicated Driver on PC
After being installed the driver, PC will recognize T2 . Here we take Win7 32 bit operation
system as an example to tell the installation procedure.
1）Power on T2
2）Plug the USB cable to connect PC with T2.
3）Open the folder in the included CD and click” “ to access to installation
interface
4）Here are tips on the installation:
Click “Next”

7
Click “Install”

5) Click "Finish" and restart the PC. By now, the T2 finishes installation.
6) Installation on Win XP or Vista OS is the same.
Note: T2 will automatically remember the connected USB port, in next time onward
please connect the same USB port.

Core Audio Stream Introduction
Core Audio Stream is generally used by the HiFi audio workstations. It has formats of ASIO,
KS and WASAPI, which all can be supported perfectly by T2.
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, that is the core audio stream technology.
T2 supports ASIO and KS on Win 7, Win8, Vista, Win XP systems, supports WASAPI audio
output on Win7 32Bit/64Bit, Win8 32Bit/64Bit operating system. For example, when you
enable WASAPI + Exclusive Mode between T2 and player software (like JRiver), you can't
control the volume through system controller, the sound from the system and other
applications will not be heard at the T2 output, which is because the system has opened the
core audio stream channel for T2 and the audio data directly get to the DAC of T2 with
high-speed.
If you don't set the output to be the core audio stream, you will find the sample rate shown on
T2 is different from that of playing the original music, and it is locked at 48K or 44.1K. When
you finish the following settings, you will find that the shown sample rate is the same as that of
playing the original music, which is telling that PC can output the "bit-perfect" data now.

JRiver setup
Let’s take Win 7 32bit operating system as example, to see how to setup JRiver Media
Center.
1. Download and install
1) Click the website http://www.jriver.com/download.html , click “Windows Download” to
download the JRiver Media Center 19.
2) Install JRiver Media Center 19.
2. Import music
1) Open JRiver Media Center, find the “import...” item from “Tool” option, click it, choose
“Configure Auto-Import”. Then click “Next” .

11
2) Click “Add...”, then next screen click “Browse”, find the file where the music stays, then
click “OK” to complete it.

3. JRiver output setup
1) In “Tool” option there is a “Option” menu, click it to entry sub menu.
2) In “Audio” menu, find the “Audio output”, choose “SPDIF Out (Questyle High-end USB
Audio Device) [WASAPI] “, then click “OK”.
3）With above setting, now CAS192D can play the music files from your Windows PC
(exclude DSD files);

Setting On MAC OS
For Apple MAC OS, later versions of the 10.5.7 contain the USB2.0 High-speed audio driver,
so it doesn’t need to install another one any more. On MAC OS, all of the features including
the standard asynchronous transfer mode of T2 won’t change.
After connecting T2 to PC with USB cable, you need to manually set the output device to be
“SPDIF Output”, and then the whole system can work.As shown below:
