f20 line out

[a19als]

who know about f20 line out connecter( not dock)? where can i get it? Thanks!

I would make a cable that has a dock connector on one end and a stereo plug or RCA plugs on the other end.  If you're after the pin assignment in the dock connector, you can find it in our wiki: http://www.rockbox.org/twiki/bin/view/Main/ToshibaGigabeatFXPortPins#Dock_connector

This is the only way to access line out on the Gigabeat F20.

A better question at this juncture is actually whether coupling capacitors are required.

I've purchased some e405 cables (cheaper than buying the connector alone) - the ones i got are simpler than the one pictured in the wiki because it doesn't have a pc board - just wires soldered to the pins sticking out the back of the connector.

This means that there's room in the handle for a small kobiconn 3.5mm jack and potentially a pair of high quality 10uf caps, if they're needed.

I realize that i could test this out for myself, but i'm curious if anyone has ever actually built one of these. That and I've pretty much exhausted my free hacking time for the weekend.

Also interesting that the F and S series apparently have at least the line-out pins in the same place.

And I'm curious whether the line-out is enabled all the time or not. Apparently on the Zune 30 (a direct descendant of the gigabeat S) the line-out is disabled by default, much to the consternation of people who've tried to build diy line-out docks for them. But that could be a software issue.

EDIT - because i can't reply

Alright, I built a simple LOD connecting pins 5, 6, and 7 on the dock connector to a mini jack, 5 and 6 through 10uf caps just in case.

This DOES NOT WORK. I hear mostly silence, a little bit of noise if i turn my headphone amp way up. nothing like music.

Assuming the pinout is correct, this leads me back to my question of whether some features the dock connector has to be turned on, perhaps by pulling pin 17 ("option detect") high or low. Or possibly 27 ("main detect"). Or maybe something else entirely.

I'm mostly in the dark here. Surely someone else has investigated the factory F series dock in some detail?

Well there is that switch on the dock that comes with the gigabeat that selects between USB and lineout.  Maybe that needs to be in the circuit, but I think the switch was mostly to disconnect the USB as the player wouldn't run while connected to the PC (that way you didn't have to disconnect cables from the dock to use it for both purposes).

iirc the switch on my F series dock doesn't affect the line-out.

I'm starting to think maybe i need to connect pin 36 (ground from dock) to ground.

Is there any gigabeat line-out dock available here?
I want to get one.

You're probably better off looking for an auction at a place like eBay, or similar.  I just got a new remote for my Gigabeat recently.  I have seen docks for sale in the past.

I built a Line Out cable using the Toshiba E400 / E800 cable from Ebay, as described.   Soldering to those small pitch pins was tough on my old eyes.  You do not need coupling capacitors.

Hi there,

I just got the connector from Chris ( THANKS CHRIS!!!) and I DIY today.  The DIY cable works. You only need to connect pin 5,6&7 only.

good job!!

Guh, I see what my problem is.

The diagram in the wiki is the other gender.

Anybody know where they hid the line-out output caps in the F and S series, out of curiosity?

[ej0rge]

Alright, found more time to tinker with this today and i have a working line-out dongle - now that i understand that the diagram in the wiki is the connector on the gigabeat, not the connector on the cable.

The connector I'm using is salvaged from an E405 cable, and a bit longer in the body than most from the look of things. It turns out that with some of the plastic trimmed off, a nice little Kobiconn mini jack fits right in the thing. I know most people would prefer a cable, to a jack, but, I wanted to see if this would work at all, so i tried it. Works well, though it will need some glue to keep everything from being horribly damaged if the plug is yanked on hard.

Oh, by the way, this doesn't work on the S, so either there's some software configuration of the codec that isn't happening, or the partial pinout of the S series dock connector in the wiki is wrong, or something else is missing.
