Trying to identify sound card connectors

[ShadowTek]

I just bought an old Sound Blaster Live! 5.1 PCI CT4780. There are a
number of connectors on the board, and I would like to identify them and
know why some of them came with jumpers on various pins.
J1 - 1 row of 10 pins
J12 - 1 row of 4 pins (TAD)
J9 - 1 row of 4 pins (CD_IN)
J4 - 1 row of 3 pins
J11 - 1 row of 4 pins (AUX_IN)
JP1 - 1 row of 2 pins
J3 - 1 row of 2 pins (CD_SPDIF)
JP3 - 1 row of 3 pins
J13-2 - 2 rows of 5 pins = 10 pins
J13-1 - 2 rows of 14 pins = 28 pins (AUD_EXT)

I'm guessing that TAD stands for "telephone answering device", and the
two "CD_" connectors are obviously for connecting an optical drive. But
what are the rest of the connectors for? Are they all inputs? What can be
connected to them?

Also, JP4 and JP3 each have jumpers connecting their pins 1 and 2. J13-1
has two jumpers on it: one connecting pins 21 and 23, and another
connecting pins 24 and 26.

What purpose do these jumpers server? If I can't figure it out, should I
remove them?

That has some good info. Thanks.

I didn't see anything on those jumper pins though.

Disclaimer... I might be wrong as I'm going from memory.

Back in the day when the SoundBlaster Live! card was the daddy it came in
three different versions. Each version shared a common main sound card. The
basic version was just the sound card. The next version up had a faux-pcie
card that provided some pro-level outputs (and possibly a game controller
port) on its backplate. The top of the range model had a panel that fitted
into a disc drive bay to provide front panel controls.

I believe that the extra pins etc that you mention are used to connect these
peripherals.

Hope this helps

In article <gj4ea2$pob$1...@news.motzarella.org>, ShadowTek says...

They're to connect up the 5 1/4" Liveddrive bay thingy Creative do
which has a load of controls and inputs/outputs on.

Yes, the previously linked manual indicates that the J13-1 and J13-2 are
connected to a single plug that leads to an optional drive-bay/front-
panel accessory, in which case I imagine that thier jumpers would have to
be removed.

But there are still the 3-pin JP3 and JP4 which each have jumpers
connecting pins 1 and 2.

It would be nice to know what those are for.

OK, I'm not 100% certain on some of these, but I'll do my best. This
information is based on my Creative Sound Blaster Live CT4830, and on
some general knowledge I have as a nerd, quite a bit of which was gained
recently when researching pinouts for internal computer plugs, including
those on sound cards.

J1 - 1 row of 10 pins

This can be used to connect the front audio jacks on your tower case to
the sound card, you may well need an adapter.

J12 - 1 row of 4 pins (TAD)

You have the correct answer (telephone answering device). I'm unsure if
this is bi-directional, and I don't know all that much about it,
although a Google search should yield some answers.

J9 - 1 row of 4 pins (CD_IN)

Connect a CD drive to transfer ANALOG audio.

J4 and JP3 - each 1 row of 3 pins
Is there a jumper on either of these? Usually, a row of three pins with
a 2-pin jumper changes a setting, such as C/LFE assignment: In one
position, C will be on the tip and LFE will be on the band (and they
will ground through the sleeve), in the other position, LFE will be on
the tip and C will be on the band (and they will ground through the
sleeve). C/LFE in case you don't know is the center / sub-woofer (low
frequency emitter). if they both have jumpers, then I don't know what
the other is for, it might be the case that neither is C/LFE assignment.
If neither has a jumper, then again, I don't know.

J11 - 1 row of 4 pins (AUX_IN)

Basically another CD_IN by a different name.

JP1 - 1 row of 2 pins

Possibly for connecting the speaker or buzzer inside the tower, although
mine calls this J7 PC_SPK.

J3 - 1 row of 2 pins (CD_SPDIF)

This transfers DIGITAL audio from a CD drive using the Sony/Phillips
Digital Interface.

J13-1 - 2 rows of 14 pins = 28 pins (AUD_EXT) and J13-2 - 2 rows of 5
pins = 10 pins
This is actually 1 jumper, the reason for the separation is to allow for
two key pins to correctly orientate the plug. This jumper is used to
connect devices such as the front 5.25" bay accessory (Live Drive). I
believe there is also a version of that which fits into the PCI slot in
the case (not the one in the motherboard).

Hopefully that helps.
