ASUS Xonar Essence ST with ASUS Xonar H6 (Extension Card) + Logitech Z-5500 Digital 5.1 Speaker...

post #1 of 14

Hi all. As most of you are familiar with the ASUS Xonar Essence STX sound card, the ST model is pretty much the same card, but can also be attached to the ASUS Xonar H6 extension card, which gives it full 5.1 channel support via RCA analogue cables.

 

The problem I have is that my Logitech Z-5500 Digital 5.1 Speaker System uses 3 inputs for the analogue surround sound, but the card uses 6. On my Z-5500, I have inputs for the Black, Green, and Orange RCA cables. This is how everything is set out:

 

Logitech Z-5500:

 

Black cable: Takes care of Centre channel and Subwoofer.
Green cable: Takes care of Left and Right channels.

Orange cable: Takes care of the Rear Left, and Rear Right channels.

 

ASUS Xonar H6 (Extension Card):

 

Output 1: Right.

Output 2: Left.

Output 3: Centre.

Output 4: Subwoofer.

Output 5: Rear Right.

Output 6: Rear Left.

 

I don't know how to connect my speaker system via analogue cables to the card. The sound card itself also has Coax and Optical inputs, but the whole point of buying the extension card was so I could use the DAC of the sound card instead of the DAC of my speaker system (which isn't that great).

 

Please help me guys, I don't know what to do!

Hello, I think I might be able to help. The bad news is that the solution will cost you a little. On the actual soundcard, there should be two phono outputs (I think thats what they are called). They will be red and white I think. Those are for the front left and right. You will need a cable like this one 11994341_grob_071.jpg. As you can imagine, the phono ends go into the soundcard, the 3.5 mm jack goes into the logitech control pod. You will need another one of these cables to connect the back L/R speakers via the H6 card. Finally you will find, on the back of the H6, a channel for centre/sub. This can be connected using one of these HQCAA019.jpg. I have not tryed this, so I can't guarantee it will work. But the logic behind it seems valid. Good luck.

Didn't the TRS/RCA adapter cables come with your sound cards?

Not with the Essence ST unfortunately cladisch. I don't know what comes with the H6 expansion board, but I'm guessing that didn't include the aforementioned cables either.

The only thing that came with the extension board was the internal cable that is used to connect the actual sound card with the extension board. That adapter you were saying, is it an RCA to 3.5mm Y cable? It says on the box that one is provided, but only one!

Yes, RCA to 3.5mm Y cable sounds right. The one that came with the card is female 3.5mm I think. 3.5mm jacks combine left and right channels into one connector. With RCA connectors, as seen on the Xonar H6, there is a separate cable for left and right. The Y cable should allow you to combine the left and right from the card into one 3.5mm connector.

Make sure it is two RCA's to one 3.5mm though. Not  two 3.5mm's to one RCA.

Actually it looks like the Centre and sub channels require a Y cable too. Sorry.

I'm a bit tired, so don't take my word for it, but I think it should look something like this. That should give you an idea anyways.

I understand exactly what you mean, thank you. However, I'm a little confused about the Centre/Subwoofer channels. How will I know which is the Red and which is the White? I understand how it works for the Left and Right channels but what about these?

I understand your dilemma. After searching all over the place, I still have no answer. I think the sub may be the red connector. Will it do damage if you get it wrong? I doubt it. The sub will get the frequencies intended for the center, and the center will get the frequencies intended for the sub. I am afraid I have no definitive answer  I'll keep searching.

Well, I appriciate all your help. If you can find me an answer, I would be forever greatful to you. Thank you for taking the time to do the diagram, it really helped!

@LiquidExtreme12, have you tried to plug this center/sub cable in anyway and test with a well known surround sample? You can get here (or mirror here). It's supposed to play in this order: front left, front right, center, back left, back right and subwoofer. I think that with this you'll know if you're using the RCA plugs in the right position. :)
