V-LINK192 Asynchronous 24bit 192KHz USB to SPDIF Converter  
Instructions  
Introduction  
Thank you for purchasing the V-LINKI92 asynchronous 24 bit  
192kHZ USB to SPDIF converter. This unit is host  
computer-powered and features galvanic isolation of the  
digital outputs for optimum noise free digital signal transfer.  
It is designed for all sample frequencies up to and including  
192kHz. This enables high sample rate source material to  
be reproduced with stunning detail and clarity. We sincerely  
hope that it will bring you many years of outstanding  
listening pleasure.  
This Hi-fi product has been tested to ensure that its  
operation is not adversely affected by normal background  
levels of Radio Frequency Interference (R.F.I.), and that it  
does not itself generate excessive amounts of interference.  
However, if a problem persists, please contact your Musical  
Fidelity agent.  
Never open the case of the V-LINKI92 yourself, as this will  
invalidate the guarantee.  
Place all connecting cables where they are not likely to be  
walked on or trapped by items placed on them.  
Installation Precautions  
Your new V-LINKI92 is designed and built to provide  
trouble-free performance, but as with all electronic devices,  
it is necessary to observe a few precautions:  
Do not use the V-LINKI92 near water. The unit must not be  
exposed to dripping or splashing and no objects filled with  
liquids, such as vases, must be placed on the unit.  
Keep the V-LINKI92 away from heat such as radiators. No  
naked flame sources, such as lighted candles, should be  
placed on the unit.  
The  
V-LINKI92 will operate in accordance with its  
specifications within the following environmental range:  
Temperature 5 to 45 degrees Celsius  
Humidity 10 to 90% non condensing  
There are no user adjustments inside. Please refer all  
service work to an authorised Musical Fidelity agent.  
Power Supply Note:  
The V-LINKI92 does not require a power supply; instead it  
automatically draws  
a
small amount of operating power  
from the computer USB port it connects to.

For the other supported (non-Windows) operating systems, the  
computer drivers for the USB input of the V-LINK192 should install  
automatically. To check correct installation follow these steps:  
PC Windows users  
Check the computer has picked up the device and is currently using it  
by clicking: (most Windows versions)  
a
driver for this unit before  
connecting the input. Insert the disk into the computer to be used and  
follow the onscreen guides to setup the driver software. The software  
will advise when to connect the device.  
Apple OSX or later has the necessary functionality built-in; and does  
not require driver disk.  
A good quality USB 2.0 A to B cable is required to connect the unit to  
the computer.  
Further advanced information not included here is available on the disk  
in the form of a PDF document. To read it, Adobe PDF reader must be  
installed on the machine.

digital media system. It is advisable to have any subsequently  
connected amplifier turned down or off at this point. Coaxial (RCA) or  
balanced (XLR) may be used. Files sampled up to and including  
192kHz, are supported and the unit has the added advantage of  
inherent galvanic isolation between computer and hi-fi equipment. This  
helps avoid ground loops.

Use  
Check that “Musical Fidelity VLINK 192” is selected under the OUTPUT  
tab.  
Turn the volume on amplifier to normal listening levels, sit back and  
enjoy the music. This product has been designed so it may be left on  
indefinitely.  
If the computer’s warning sounds/chimes are to played through the  
DAC, make sure it is selected under the SOUND EFFECTS tab too.  
This device is a high speed serial data processor, and by its nature,  
requires a very high volume of USB bandwidth. It will benefit greatly  
from being the only device connected on its USB ‘port’. Sharing the  
same port with other devices may cause unwanted artefacts such as  
dropouts or temporary loss of signal. This especially includes the use of  
the DAC on a USB hub/splitter alongside other USB components.  
Digital Coaxial output RCA  
Please note, no sample rate conversion takes place in this unit, lower  
sample rate files, e.g. CD-originated music are simply passed through  
at their original sample rate. Other file types such as MP3, WAV, FLAC,  
AAC, etc are passed through with the same sample rated as stored on  
the computer.
