I have an older Kenwood Excelon HU. I have the Aux input running a 1/8" plug so I can connect a MP3 player through its headphone jack. Right now I'm using my Blackberry, which has a 8gb mini-sd card in it.

Would I get better sq going from the usb input on the blackberry vs the headphone jack? And if so, any way to get the 1/8" plug adapted to USB?

thx!

 

USB is a digital bus so the signals on it are digital. The data on a USB connection can be many things- music (in MP3, AAC, many other formats) and data (titles of songs).
A 1/8 (mini) jack is analog - can be connected to earphones, headphones, speakers.
The two will not connect without some conversion - and the conversion is not simple.
Just to pick one example, an Ipod (or your Blackberry) converts digital music to analog - you connect earphones (via a 1/8 inch mini-jack).
I know of no "box" that converts from USB to 1/8 mini-jack.

 

interesting. thanks. so there is some coversion from digital to analog to get the sound out of the earphone jack, but there is no converter to do this outside the box?

 

why not buy a usb to headphone adapter from ebay..there like 4 bucks...

thats if this so called 1/8 jack is a 3.5mm in canadian terms.

there is an example...(for bb storms)

 

thanks for the link. The only reason I would want something like that is if it would improve the SQ. Based on some responses, it doesn't seem like that's the case. I remember that for an iPod, there was an arguement that using the iPod connector at the bottom of the iPod would give better SQ than using the headphone jack.

 

Even if it were easy to do it would not improve SQ.
