Prelude 7.1 and Z-5500s Connected By Optical Cable

post #1 of 5
Thread Starter 
So I have my Z-5500s attached to my Prelude via an optical cable and when I have the Control Panel Sound Manager set to "Speaker" I do not get any sound. Also the display shows "Optical - No Digital Input". But I do get sound when I switch Speakers to SPDIF-Out. My only problem is that under SPDIF-Out, everything shows as a 2.1 speaker configuration.

How can I fix this?

Thanks.

What are the other settings as far as the "Speaker" goes. Like is there anything else to choose from.

My two options are "Speakers" and "SPDIF Out". Speakers is the only device I can configure to 5.1 sound. SPIDIF Out doesn't give me those options.

So I've ditched the optical cable all together and just have it plugged in as 6Ch Direct (3.5mm jacks). Everything works fine.

But I really want to use my optical cable for the improved sound quality. Under SPDIF Out, it's only 2 channel audio. Under Speakers, I don't get any sound at all.

You will actually get better sound with the analog outputs than the digital, as funny as that might sound. No pun intended.

Okay for you to hear any sound one of the devices, the soundcard or speakers has to convert the digital signal to an analog signal. This device is referred to as a DAC or digital to analog converter. In your case the DAC's on the Prelude are actually better than the DAC's in the speakers amp. They are both 24 bit, but the prelude has a slightly better sampling rate.

Now that you know this let me explain the wiring. When you connect the speakers via the soundcards optical(digital) connection you are bypassing the DAC on the soundcard and forcing the speakers to do the converting. When you connect the speakers using the 3.5mm(analog) connection you are using the Preludes DAC and bypassing the speakers. The result better sound.

So long story short use the 3.5mm plugs.
