Ipod classic 6th generation output level too high

(1/4) > >>

Hello,

so far I am new here. I am glad that there are people developing this software and also helping each other. Last week my HD broke at my Ipod classic 6th generation.
I replaced it with an 256GB SD card and I had to find out that not the hole amount of memory is supported by Apple. Thanks to RockBox I am now able to have about 240GB of memory at my Ipod. Unfortunate my external DAC don't get any signal over the cable. But I have to live with that.
So I have to use the headphone jack, but even with -60db it is way to loud to listen. I have not done anything at the EQ mode. But I found out that in the EQ mode I am able to have an preamp setting of -24db. It is better now and I can listen music, but sometimes even this is too loud. The Ipod shows me the speaker signal with an cross.
May one of you have an idea what is wrong. Buy the way I am using the "ClassicRockBox" from this homepage:

At the RockBox.org homepage I couldn't find my Ipod classic 6th generation model.
Thank you for your help ...

What headphones are you using ?  -60dB is an extremely low signal level.  Its hard to believe you'd want to go lower than that?

Hello,


thank you for your answer. I cant believe that the -60db are true. I am using the Audio-Technica ATH-CM700Ti. It is so loud that if I have both headphones on, that after a couple of minutes I have to put them off. So I believe that it cant be -60dB. I will try to organize original Apple headphones. I will let you know if I have tried them. But I guess there will be not much difference.

Something has to be very wrong here.

I can't exactly say what, but, something is very wrong.

You did state that you had modified the device internally, so it is possible that you have damaged the hardware in some fashion.

Not only should -60dB not be intolerably loud, it shouldn't be perceptible, at all. -60dB is functionally equivalent to "mute", inaudible.

The monitors you're using are of no consequence here, I have a range of monitors of varying degrees of precision and response (my usual "daily driver" monitors being UE18 Pro full costom in ear monitors, and not a one of them behaves in such a fashion. I too, for what it is worth, use a modified iPod 6G (several in fact), ranging from 128GB compact flash to 512GB mSATA, and I do not see such an issue.

Those are about 118 dB/Vrms, and the iPod puts out almost 1 Vrms at 0dB, so you would be listening at a maximum volume of 58dBA, or roughly normal human speech volume.

Are you sure the volume is actually working?  If you change it, does the loudness change?
