Suround sound

Hi I am long overdue for a new motherboard. Currently mine is an Asus
2005 make. I was looking at this

GA-MA785GPM-UD2H/

It states 7.1 suround sound. That I beleive is an 8 Speaker system. I
only have 3 connections.

Center/Subwoofer Speaker Out Jack (Orange)
Rear Speaker Out Jack (Black)
Side Speaker Out Jack (Gray)

How does this work? Is there a website for showing diagrams?

What if I just wanted plain sterio with 2 speakers.

Could do with some input on this one.


TIA

Desmond.

If you look on p.88 of the manual, there's a diagram of how to hook the speakers for different configurations:

This is strange. I am used to a left and a right channel for sterio.

Front speaker out is just one speaker or two speakers wired together.
Not seen this concept before.

Front Speaker Out is a stereo jack; left and right channels incorporated into a single jack with (L+) and (R+) out and a
common ground. If you have stereo speakers with a single jack on each one, you can get an adapter to plug the speakers
in to, then plug the adapter into the Front Speaker Out jack.

Ok the PDF said front speaker not speakers. If I have to make the
leads up ist there a proper wiring for the sterio jack. ie tip = right
middle left?

On my headphones, the tip is left, middle right, and the large part is common. Whether or not that's a code standard, I
don't know. Wire yours temporarily and see it's the same for you. If not, just swap the tip and middle wires.

I think that's what I always find, is tip is left, ring contact is right,
sleeve contact is ground.

The fact Des is asking this question, suggests the usage of non-amplified
speakers.

Computer outputs today, expect the usage of a stereo (receiver/amplifier) or
"computer speakers" which have the amplifier inside. The computer output is
typically too weak, to drive passive speakers.

Anything amplified, is likely to have stereo 1/8" cabling (or on professional
gear, they use a larger connector of some sort).

The RCA/Cinch connector, is used on raw speakers. And would need an
adapter, from two RCA/Cinch to a stereo 1/8" plug.

For example, this adapter converts 1/8" to two RCA/Cinch connectors. But
if you think you need one of these, there is a chance you're missing
the "amplifier" part of the solution. I own a couple of these, because
my old amplifier/mixer had Cinch only on the back, and to make
a computer connection, I needed this to get from the computer,
to something the amp/mixer could use.

This is the male version of RCA/Cinch, and I have these on some speakers.
Since the passive speakers in that case, are a heavy electrical load,
I need an amplifier to drive the speakers, and not the computer directly.

The output on the computer, is strong enough to drive headphones. It'll
drive around 1 volt rms into a 32 ohm load, as an example. And if a passive
speaker is connected to that, it won't be very loud at all.

The right drivers and headphones are enough. You don't need a spiffy
keyboard.

Just for testing.

Use them for roughing in a couple amps to reference monitors at their
respective strengths

Polish the mix expansion over compression limitations into a Xenyx 802
mixer

Where a keyboard then can start for a minimum at IR, as it'll take a
modified swivel and roller office chair for spinning around in between
all the controls. Everything's Logitec these days, anyway.

Basically sourced out for stereo without a ton of downmixes, no need
for any higher emphasis past the same OPAMPs on a laser modulated
signal feed to the Ultracurve Pro.
