AmarokCZ: Thanks. I added the two resistors, and it does lower the volume. It makes the Zero usable with my Shure SRH840, although just barely. If I'd like to lower the volume even further, could I do the same thing with different resistors?

Quote: Hey, that's interesting. Is this something you've already done yourself? And do you know how much the volume is lowered in dB, by adding these two resistors?   I'm actually also considering to just send the unit back and get a refund. What good is a headphone dac/amp that can't...

Chetlanin: I built what you suggested and it works. I did it externally with male and female 6.5mm plugs and some resistors. At least I can use my Shure SRH840 now. The sound quality isn't very good though. It sounds very grainy in louder parts of the music. I can't tell it this also happens...

  Quote:   Quote: Thanks for the advice. The reason I assume it's a linear pot is because it's labeled "B100K", and from the info I found the 'B' means linear. I also found that logarithmic pots (or audio pots) are usually used for audio amplifiers, like you said. (Strange that...

Hi Olaf, Thanks for the explanation. I've tried to draw a little schematic to see if I understand you correctly: [signal]----[50K resistor]---+---[5K resistor]---+                              |                   |                              |                   |                        ...

Hi everyone,   I just received my Zero dac/amp and I found it to be very loud. With my 250 ohm Beyedynamic DT880 I can't turn the volume up to 25%. If I want to use my Shure SRH840, 44 ohm, I have to lower the volume of my audio player application (foobar2000) to 15%. But I really want to...
