To Doug Schneider,
I have one issue here, and I would like to get an answer. I am using a Squeezebox Touch as a music streamer and connect it by optical cable to the digital input of my Peachtree Audio Decco2, which is a DAC and integrated amp.
What surprises me is that the Squeezebox Touch onscreen volume control is still active while it is only transferring the digital signal. I e-mailed Logitech support for an answer and they replied that “Usually the volume should not effect the output when using the coaxial or optical digital outputs on the Squeezebox Touch. The best thing to do would be to put the Squeezebox Touch to full volume and then just adjust the volume on the amp from there.”
I still don't understand how the volume control is still active when only outputting a digital signal. I hope you can give me some answers here.
Thanks,
Jim Xing
It’s been a long time since I’ve used a Squeezebox product, so I asked fellow writer Jason Thorpe about it. Jason regularly uses various Squeezebox products and constantly extols their virtues. He confirmed what I suspected -- the Touch has a digital volume control, so it can attenuate the volume when using it as a DAC or, as you’re using it, a digital “bridge” to another DAC.
Volume controls that operate in the digital domain attenuate the volume by truncating bits. Every time you lose a bit, though, you lose resolution. Jason said that you can disable the volume control using a menu option or, as Logitech suggested, putting it to full volume to pass the digital stream unaltered. . . . Doug Schneider
