Your Two AC3 inputs are probably "Digital Coax" inputs, They use the same
RCA input connector as analog inputs do.
For AC3 you can use a Digital Coax cable from your DVD player or other
source or fibre optic "Toslink".

Also note that you can't use standard audio patch cables for Digital Coax,
you'll need to get a special cable for that. Radio Shack used to sell
inexpesive digital coax cables, check there.

The things that confused me a

1) There are TWO inputs.

2) The AC3 inputs accept analog.

The cable is now in the post, I'll soon find out....

Technically AC3 is 6 inputs (5.1), but usually one connector.
I don't see anything wrong, really.
Just hook it up and see if it works !

Mine is similar to the silver one shown under SV-2803, but mine is
black, and the LED display is a litttle redesigned.

I see that other models on that page actually mention "AC3" and "dolby
surround" but mine doesn't, I'm getting more confused by the minute!

When I get the TOSLINK cable, I'll be sending it back if it doesn't
work....

The Skytronic page doesn't have it:
http://www.skytronic.co.uk/search/index.php?cp=81

It has 5 speaker outputs makred "centre", "main left", "main right",
"surround left", and "surround right".

I can't see why there would be 5 outputs marked as such if it was just a
stereo amp.

The instructions are very cheaply printed and contradict themselves and
the back of the amp in several places.

The outputs for example are either 6 ohms, 4-8 ohms, or 8-16 ohms,
depending on what you read.

But that doesn't concern me, what's annoying is the instructions refer
to SIX AC3 inputs suggesting to connect them to a DVD player.

There are TWO on the back, not six.

And I thought AC3 was ONE input, digital all channels on one phono
socket or TOSLINK connector?

I've got an adaptor to take the toslink from my sky box, and the output
of that adaptor is ONE phono socket.

Looks like either my amp is not dolby at all, or the AC3 input doubles
s analog aswell?

Would this be possible?

I still don't managed to get hold of a TOSLINK cable, so I can't try it
yet.

Perhaps you have a brand and type of the amp ?

I've bought a cheap amp that said "AC3 input" in the manual.

On the back are 4 sets of inputs. 3 of them are standard dual phonos,
marked tape, cd, and tuner (left and right of each). The other is
marked AC3, and also has two phono sockets (marked left and right). I
was under the impression that AC3 was the bitstream format of dolby
surround sound and required only ONE phono connector (or an optical
toslink connector). Why do I have two phonos? I don't have the ability
to give it a dolby bitstream yet to test it (waiting on a part), but I
did try connecting a standard stereo analog input to the AC3 phono
connectors, and it worked. Should it have? Could it be an
analog/digital input?
