Can you set up an 8.2 speaker system with a Turtle Beach SC?

What do you mean 8.2?

The santa cruz has 6 channels.
Center, Left Main, Right Main, Left Surround, Right Surround, LFE.
It can also operate minus Center/LFE, and minus Center/LFE and Surrounds.

You can hook up 10 speakers to each channel if you want....

Or you could get 2 sets of speakers with 4 inputs each, split the main and surround outputs, and just double up....

How do you want to arrange these 8.2 speakers?
There are not 10 channels coming out of the card, nor is there any current use for 10 channels...so you have to double up somewhere...you can double up all you want. Though I fail to see the value of doing so...

I know that Insane3D has a Klipsch PM v2 8.2 setup. His neighbors just LOVE him! Don't know what soundcard he runs though. PM him.

Why would you want 2 sets of klipsch promedia's? Why not just get like digitheater dts?

What is the point? There is only 6 channels and even if there was more there is no media to support it, DVD's in 7.1 DTS-ES or DD EX. The SC will still be 5.1 no matter how many speakers you put with it.

Save your money.

It's possible, and if you setup you speaker placement correctly, it is very effective. Like MichaelD says, I run two sets of PM's for a 8.2 setup. You can't hook up each pair to it's own channel, you need to share the connection, but if you are careful about the placement, it works very well. I had them setup on a Philips AE, and now I am using the Herc GTXP. You really must plan the placement because two pairs share the front channel and two pairs share the rear channel, so if you mount one of the front pairs in the rear of the room, sound placement can get funky. If you need some help, you can PM me and I will try to help you out. What speakers were you going to use?

"Why would you want 2 sets of klipsch promedia's? Why not just get like digitheater dts? "

I went through this before when everyone told me I was wasting my money on the PM's. I bought a set of PM's, and I was then given another set as a gift. It was kind of a hassle to return them, so I figured out how to use them together. Also, my neighbors do hate me...;)

Rock on!! I use 8.2 ProMedia's and the same GTXP (Insane3D...nice to see you got your card and everything hooked up).

But, we are not getting anything better than 5.1 sound as PowerDVD and all other software DVD players havea not been updated to support the DolbyDigital EX surroundsound mode. BUT, the GTXP is ready for it and it's just a matter of time before PowerDVD releases 8 speaker support (hopefully 7.1 will be released very soon).

I'm confused there are only a maximum of 6 outputs therefore isn't 6 discrete channels the maximimum, 5 full range and 1 LFE. Even if the software could decode the new ES/EX formats there is no card with enough outputs.

My personnal opinion is more speakers will only confuse the sound. People even argue (if in the sweet spot) a center channel is not needed.

More than 2 speakers up front is going to destroy your soundstage and imaging as speakers are sharing the same information.

When you see a figure like 5.1, 7.1 it means 6/8 discrete (has its own signal) channels. 5/7 being full range and the LFE limited to low frequencies only. 10 speakers and a sub is not 10.1

Actually, if you pay attention to placement, it works fine. I have argued with people about this endlessly who think my postioning is all wacked and sounds terrible, but it is accurate and pleasing. I have the four speakers sharing the front channel in front of me, and the four sharing the rear channels behind me. They are located as such that postional audio is very accurate. For instance, both my rear right speakers are behind me and to the right, and both my rear left speakers are behind me and to the left and so and so on... As for the new 7.1 standard, this is what MasterHoss is talking about...

From the Hardcoreware.com review of the GTXP...

&quot;The GTXP uses Cirrus Logics latest consumer audio chip, the Crystal CS4630. The CS4630 is a pretty impressive DSP, providing the compatibility for DirectSound 3d, EAX 2.0, A3D 1.0, and Sensaura's MacroFX, MultiDrive, ZoomFX, and EnvironmentFX. It also handles all of the audio tasks you can throw at it, when testing using ZiffDavis' Audio WinBench CPU utilization was next to nothing, so you can rest assured that while playing mp3s or fragging someone in quake3 it won't be the audio that is slowing you down. The 4630 also has a dual codec interface. What does that mean? Well each codec can handle 4 channels for a total of 8; most 6 channel sound cards have one 4-channel codec and one 2-channel codec. The GTXP currently uses the 2 extra channels for the independent headphone and microphone jacks on the front but it could be adapted to the new 7.1 AC-3 standard that is being tested.&quot;

does it degrade the quality to split up the signal like that? It seems like you'd have to turn up the volume a little higher since the internal amp in the sound card would have to output to more speakers than its made for. And from what I know about audio (very little) if you reduce the amount of amplified power you get a higher signal/noise ratio.

The resistance will change, for example if you have a 2ch setup with a combined total of 8ohms if you doubled the speakers you would be at 4ohms which would be a much harder load on the amplification resulting in more chance of distortion.

Only 2 speakers are needed up front to create the best soundstage and imaging, adding speakers will make it more difficult to achieve the same effect and likely confuse the sound. Home Cinema setups have center speakers to counter the fact that not all veiwers will be in the 'sweet spot'
