DIY Line Out Cable - Works!

Line out is clearly specified as a 700 mv RMS P-P signal.

 

When you connect to the dock,  it should drive this level and you adjust the volume on your stereo.  When you remove the device from the dock,  the headphone setting is restored.

 

This is the way it works with the other Sansa Devices,  and docks,  including View… 

 

There are two different outputs one for Line out and one for Headphone,  but they share the same DAC.  VOlume adjustment is done in the analog domain,  and digital attenuation at lower levels.

 

So generally speaking,  fixed line out will offer the best SNR signal for your stereo.

 

Using the Sansa Base station,  you can adjust the gain of the preamp using the remote,  but the line level should be unchanged.

 

If you want to use a variable output,  you can connect the headphone output directly to your stereo.

Hi sansafix

I don’t understand how the volume is adjusted. 

In my Fuze, at 100%, the volume out of the headphone jack = the volume out of the line out dock.

Where is the analog amplification applied and where is the digital attenuation applied?
