Musical Fidelity M6 SDAC, Instruction Manual

8 

For PCs running older Windows operating systems, 
a driver download is required . This is available from 
the M6s DAC product page on the Musical Fidelity 

website. You can also find additional details about 

driver setup on the Musical Fidelity website .

Any device that is compliant to the USB Audio Class 
2 .0 standard should also operate with the M6s 
DAC .  However Musical Fidelity are unable to provide 
support for operation with anything other than the 
system listed above .

Additionally, the use of third party software such as 
“ASIO” or similar is not supported by Musical Fidelity . 

In case of difficulty with any of these software types, 

please consult the relevant software documentation 
and/or its support services . 

CD, MP3, WAV, AAC/+, OGG, FLAC, and any other 

audio file types played on suitable playback software 

will now play through the unit . 

Outputs

On the rear of the unit are 2 sets of outputs . RCA 
(single ended) and XLR (balanced) . 

You can connect the M6s DAC to your amplifier using 

whichever is more convenient . 

The outputs can operate as either fixed or variable  

mode . Fixed mode is suitable for connection to other 
equipment which offers a volume control . Variable 

mode allows connection directly to power amplifiers 

or active speakers where the M6s DAC provides the 
volume control .

Choosing between these settings is done by using 
the small switch 

13

 on the back panel . 

When in variable, mode the output level can be 
controled by either the volume knob on the front 
panel 

7

 or the remote control .

Headphones

The M6sDAC also includes a high quality headphone 

amplifier. 

Connecting headphones to socket 

6

 will automatically 

mute the main outputs . The volume control on the 
front panel 

7

 or the remote control now adjust the 

volume sent to the headphones . 

Whilst headphones are connected the MUTE 
indicator on the front panel will be lit to indicate the 
main outputs are muted .

Note: This USB input has 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 
‘bus’ . Sharing the same bus with other devices 
could cause unwanted artifacts such as dropouts 
or temporary loss of signal . This especially 
includes the use of the unit on a USB hub/splitter 
whether alongside other USB components or 
not . A direct connection to the host computer 
by shortest USB 2 .0 lead possible is very much 
recommended .

Note: When headphones are connected to 
socket 

6

 and the back panel Fixed/Variable 

output 

13

 is set to variable mode, the volume will 

remain at the volume set by the volume control 
if the headphones are removed .
