Connecting to a subwoofer.

[nuraman00]

I have a ROG CROSSHAIR VII HERO (WI-FI).

How do I connect it to a SVS SB-2000 Pro subwoofer?

I tried connecting a RCA cable from the orange port on the on-board sound card, to the LFE port on the woofer.

Two problems.

One is that the cable doesn't stay firmly into the orange port.

The other is that the subwoofer makes a loud hum.

I also currently have a 3.5mm to red/white RCA cable going from the green port on the sound card, to my powered speakers.

Here is the manual for the motherboard:

The orange port is a 2 channel output just like the green port. It is the sub + center channel. So you should be connecting another one of those 3.5mm to 2xRCA breakout cables and only connecting one to the sub. I don't remember off hand whether sub is the "right" or "left" channel but you'll know when you have the correct one.

However, I don't know if there is a 2.1 mode in your audio control panel. If you set it to 5.1 you will get output from the sub channel but you won't hear any audio intended for the other surround channels. Often dialog is sent to Center so you might get really weird sound. In such a case you'd be better off using stereo output to your sub and then connecting your speakers to the sub.

You are right there isn't a 2.1 mode.

I set it to 5.1, then on the next screen, unselected center channel, and rear speakers.

Then it asks which speakers are full range. At first I unselected both front and subwoofer.

However it still didn't sound like it was using the sub.

So I went through the configuration again, and selected them both as full range.

It still didn't sound like it was using the sub.

Also, I tried connecting both RCA to the LFE inputs on my sub, as well as connecting only the red one.

It still didn't sound like it was using the sub.

I can hear the dialog and music, it just doesn't seem to be using the sub.

BTW, I am now on a PB-2000 Pro.

Ok, I opened up SupremeFX and selected "enable bass management".

When I do the audio test, everything sounds right. Left Channel, right channel, subwoofer.

But when I play something, it doesn't sound right.

I even tried the setting to "swap center / subwoofer output" that's in the SupremeFX.
