Are you using the TC as a DAC? - The problem is certainly within the TC or more likely whatever the TC is connected to. S/PDIF cannot distort or overload in the conventional sense, because there is nothing higher than 0dB so if the distortion goes away when you lower the volume it must be

Yes I’m using the TC as a DAC for my SB3. The TC is a professional device that has very high headroom. Distortion is maybe not the correct wording. It is difficult to describe; maybe saturation is a better word. Vocals are usually the material where this ‘saturation’ is easiest to hear when it

Yes, all DSP functions in the TC are off. There is nothing in the TC that is further amplifying the SPDIF signal. The TC’s output is fed into a Cambridge Audio 840E preamp which should be able to handle it. -- Pascal Hibon 2 x SB3, 1 x SB Boom and 1 x SB Radio - all wireless ReadyNAS NVX

I’ll do some measuring to find out. I’ll report back with the results. -- Pascal Hibon 2 x SB3, 1 x SB Boom and 1 x SB Radio - all wireless ReadyNAS NVX running SBS iPeng on iPod Touch. Vote for Tone Controls on SB Radio: http://bugs.slimdevices.com/show_bug.cgi?id=15436

Well, well, don’t I feel stupid now... Can’t believe I missed that one! I did my measurements by running a WAV file with a 0 dB / 1 kHz sine wave signal through the SB3. The output of the TC is indeed way too high at 0 dB digital in. I lowered the TC’s output stage so that it outputs 2 volts RMS

My SB3 is connected to my TC Electronic Konnekt live http://www.tcelectronic.com/KonnektLive.asp by means of the coaxial SPDIF. I had my volume control set to fixed (100%). I’ve notice on several occasions that with certain songs there is a kind of distortion audible. Today I decided to have a
