BTW, FWIW, the company both of us worked for went bankrupt, FORTAN, COBOL & interpretive Business BASIC exectuting on multi-user interactive Unix O/S hardware platforms have gone the way of the dinosaur; its all MS Windows, GUI and class based OOP.

At my heyday (as previously mentioned), C++, VB, and Java came out (aloing with SQL) and countless other multi-medai technology.



I've been picking it up over the last 12 months at the local junior college. SO, by this time next year, perhaps I may actually know enough to comprehend that the "microcode" isn't ASSEMBLER (which is what it looks like to me right now).

The main thing is that I have crappy rear speakers; I need to tighten up their input significantly so as to work within their rules.

FWIW, I had my 44w PC system sounding absolutely incredible (it was cooking so well that I HAD to make adjustments to my Sony STR-1070x - meaning I had to figure out sound pressure levels). SO I figured out my rear delay was 2x the room depth, but the rear dB was 2x what it should be when considering the reflection off the back walls from the front speakers.

Wow.

It is hard to say, as AFAIK the CT4780 is not a 5.1 model, so the 3rd SPDIF would probably only be available on the header. In any case, with kX it doesn't really matter since AC3 passthru is not supported on 10K1 models.

Duno what to tell you in that regard.

AFAIK, the CT4780 implements on the 4-pole 3.5mm mini-jack on rear bracket:

Center & Sub-woofer

Front, Rear, Center & Sub-woofer SPDIF outputs

The CT4760 4-pole 3.5 mm mini-jack on the other hand garners:

Center & Sub-woofer

I did some in-depth research into this question and I ascertained that the CT4760 surround-speaker systems (whether 4.1 or 4.0), have front/rear analog & digital-surround input-jacks (requiriing the analog F/R oututs).

The CT4780 is different in that if the card configured to DOO, ALL output can be obtained on the 4 pole 3.5mm mini-jack - without use of the analog F/R 3-pole mini-jacks whatsoever.

My problem in that I have a 2.1+2 surround speaker system (the rear speakers being LCS-150). So my interest was in cut-off frequency for the rear channel. I think I have that figured fairly well: speaker test works good.

Can you recommend some speaker that may be ancient, but worth $10/ea. (plus shipping) on eBay?

I understand that a sow's ear can NOT be made into a silk-purse, but still, man. There has GOT to be a whole hell of a lot of crap out there that's better than what I'm using.

Hmm, I do not know where you got your info (unfortunately, detailed, model specific info is hard to come by these days for some of these older cards), but it does not *seem* accurate (but I could be wrong, of course).

Again, Live! models are 4.0 cards, and as such would not have analog Center/Subwoofer outputs.

What you describe here is a typical Live! 5.1 card. AFAIK, the CT4780 is not like this. It does not have analog Center/Sub... As for the digital outputs (via the digital out jack), I suppose it is possible, but it seems unlikely. The only reliable info (specific to the CT4780) that I could find is from the Dell website, but it does not give detailed info about the digital out jack: https://support.dell.com/support/edo...En/connect.htm

4.0 speaker systems are (uhm ) 4.0, and as such the analog F/R is all that is needed, so I am not sure what you mean. Also, most early 4.1 speaker systems did not have a discreet subwoofer channel (sub was derived from the other channels via a built in crossover), so again, analog F/R would be all that is needed for 4.1, when using such speaker systems.

However, provided that you have some external DAC, the digital output could be used for whatever you choose, so it could be possible to gain extra channels that way (depending on whether the card allows the use of both the analog and digital outputs at the same time).

Also, when using AC3 compression, you can get 6 channels (compressed) from a single SPDIF connection, so that is another way you could get more channels than the card technically supports (but only with AC3 content, and only when connected to an external decoder).

I cannot recommend anything off-hand, but your best bet is probably to just get another 2.1 system (with built in crossover) for the rears, or just get a 4.1 system (again, with built in crossover, so that the speaker system does it's own bass management (maybe something like the old Cambridge Soundworks FPS systems)).

The thing is, I have a "yellow" jack, so your link is probably less pertainant to:

Sound Blaster Live! Sound Card (SB0200, after Oct. 15, 2002)


than the Sound Blaster Live! Sound Card (CT4780, before Oct. 15, 2002)

I stand by my statement.

To Russ:

W'e're still friends, eh?

eBay listing to my card

The link you posted is for the SB0200 (which is a 5.1 model), not a CT4780.

Hehe, it's all good

OK, so the jack is yellow instead of white, but I am not sure that should make any difference. The SB Live! Value used a yellow jack for digital out (or maybe digital I/O) too. Also, note what the jack looks like on your card, as it does not look like a 4-Pole jack. Take a look at the following picture (SB0200): http://upload.wikimedia.org/wikipedi...ivedelloem.jpg

Look at the yellow jack, note how it differs from the jack in your picture. This is what a 4-Pole jack typically looks like on these cards, whereas the one on your card looks like a typical stereo jack.

BTW: The SB0200 (Sound Blaster Live! 5.1 Digital (Dell) OEM)) is an oddball model, this page has some pictures of more typical Live! 5.1 models (as well as some others).
