Post subject:  Colour coding for Onkyo decoder component surround sound
I've just bought an Onkyo ED-901 decoder (still waiting on delivery) and managed to find some documentation on line, but there's one thing that isn't clear. The one I'm buying has a D-connector leading to six audio phono plugs which are presumably the audio channels for an amp with component surround sound input (which I have).

Image

Unfortunately the documentation doesn't mention this lead or say which plug is for which channel. I'm reasonably sure I can figure it out, but if anyone does have this equipment and can tell me it might save some time. I've asked Onkyo, but haven't heard back yet.

Black can also be left....

The cable on the photo doesn't look the original.... so the colors will tell nothing...
Maybe the pinout of the d-connector is somewhere on internet? Than it's easy to measure wich color is for wich channel.

Black might also be Audio Right because they don't want you to confuse the red cable of the split color cables from the component video connection with the red cable for audio.

it could be up to the user, like for sacd inputs.

DB25 (THX)Pin outAssignment

The following is the pin out assignment for the DB25 connector used on manycomponents such as those from Onkyo, Rotel and others. Thesecomponents consist ofReceivers, decoders, Preamps and amplifiers. You can use these pin outsto construct your own DB25 to 6 RCA, 6 RCA to DB25 and DB25-DB25 inter-connects.

Pin 1 left
Pin 14 left ground
Pin 2 center
Pin 15 center ground
Pin 3 right
Pin 16 rightground
Pin 4 Low frequency signal (subwoofer)
Pin 17 Low frequencysignal (subwoofer)ground
Pin 5 left surround
Pin 18 left surround ground
Pin 6 right surround
Pin 19 rightsurround ground

Excellent - that and a multimeter should sort this out.

Most test disc like video essentials include test signal for audio. Video essentials dvd and ld have test signal for each individual channel. You can figure out which is which using one of these.
For example select center speaker test signal, the only active rca connector will be the center channel. Then switch to front left, the only active rca connector will front left. Within 5 mins without any tools you can figure out each of these

Unfortunately I don't have a test disk for audio - I've got a couple of disks with video test patterns at the end, but nothing for audio.

It arrived today and I followed those pinouts to get

Black - rt. front
Red -lft. front
Blue -lft. surround
Green - rt. surround
Yellow - centre
White - sub

I don't think it's a professionally-made lead, partly because of the odd colour choice and partly because whoever made it swapped the earth and live for each connector, but it seems to work so I'm not too worried; tried it with a crime movie with lots of echoey gunfights and everything seems ok. Not 100% sure I have the delay right; the surrounding speakers are about 10ft to my left and right, does 7 milliseconds sound ok?

Later - forgot to ask, can anyone recommend some good titles that show the capabilities of AC-3 sound? I don't have an actual sound test disk, unfortunately.

Is this a rf demod as well?

Yes, AC-3 RF to component sound. Also has digital and analogue inputs for other sound sources, but my amp is already pretty good in that respect so I may never use them.

An odd PS to this - I heard back from Onkyo UK last night, they had no information on this at all, and were waiting to hear back from Germany. So I sent them the list of pinouts and plug colours, with acknowledgement of the source as this board, and they ended up thank me for the information...

As you can see from the guide in my signature, the CEA-863-A standard defines the following colour code :
White — left
Red — right
Green — center
Blue — left surround
Gray — right surround

And the Sony MST-2000 has rear-panel jacks coloured as follows :
White — Left
Red — Right
Gray — Center
Lavender — Left Surround
Black — Right Surround

Unfortunately the lead I got didn't follow that standard.

Hey all, just thought I'd add to the confision regarding the DB25 connection on the Onkyo ED901.

Here is what I have:

I purchased my unit through eBay and the seller included the dongle above and the diagram below.

YMMV

Apologies - must have missed this when you originally posted it. I think the confusion is because your lead is for audio input, mine is for audio output.

A belated PS to this - I picked this up in a car boot sale (swap meet) today

Image

Suspect it's a cable for either this amp or the decoder, or something similar. There are ten female phonos, they're mostly labelled but some are barely legible. What I think they say is:

Out 1 (L)
Out 2 (R)
Out 3 (L)
Out 4 (R)
Out 5 (L)
Out 6 (R)
Out 7 (L)
Out 8 (R)
in 1 (L)
in 2 (R)

What I can't figure out is why there are no centre or subwoofer sockets.

Anyone got any ideas?

Unfortunately I no longer own the Onkyo decoder so can't test it.

Could also be a cable for a soundcard or a multitrack audio recorder (I have a few of them)

That's plausible. Thanks for the suggestion, I never thought of it.
