May be E-MU want to position this card a lower end product than 1212m?

It's Lan

Yes they cut some features out like 192khz, ADAT, and balanced I/O. It's a "cheaper" product afterall. I don't really see lack of 192khz being that much of a loss.

Let me rephrase, it's the same testing conditions.

Lan = my bad :lol: The specifications of the AK4395 is pretty good as well - gets me worked up this card! Please someone lend lan a stock EMU1212 so that he can tell everyone how it sounds like against the EMU0404!

balanced I/O is a good idea, but I don't think I can ever afford an amp that has balanced inputs ...

I think ADAT is also reserved for professional needs? If that's the case, then this would make a great consumer card!

BTW, what's with the rolloff in the analog outputs of the EMU1212/1820, as seen in the RMAA charts at digit-life.com?

They measured with another more professional device not RMAA and there wasn't as much rolloff.

ADAT sounds better to me from my RME to emu 1820m compared to configuring the optical as SPDIF. But that's a limited case scenario.

I wouldn't call this a great consumer card. The driver/interface has a steep learning curve and is still more like for the prosumer.

Does anyone know of a place to get the 0404 for less than $100 shipped?

It looks like Guitar Center has it, you can probably get it from them for $75 since they have it listed at $149.99 and will usually go to half of their list. It's hard to say, though, you might be able to get them down into the $60 range.

would you mind stripping off those E-MU E-DSP stickers? I wonder what's that smaller chip on top, my guess is some Xilinx.. also wonder why so many opamps related to the DAC, there are at least two dual opamps there, might be balanced up to that point and summed on the opamp near the analog connector or might be filter + buffer for each channel.. is that opamp near the D-SUB related to output or input? also try bridging those elyt caps in the signal way if those are what I think they are

 

[alexm]

ehm, it's just me or the clock circuit is different from that in 1212m/1820m ?

great scan lan, thx

 

[Glassman]

you're right, there's just one oscillator, this card *could* be 48/96kHz only

or there's kind of PLL generating whatever freq needed (I hope)..

The DSP stickers are kind of sticky

I'm leaving the card in for a while to burnin. I really don't know if that opamp near the Dsub is for input or outpt. iit is closer to ouput stuff though.

The clock stuff is different but it doesn't affect quality that much.

It's a digital photo not a scan

that was my impression, still I think it's safe to assume it doesn't resample, taking into consideration listening results by Lan and the words of an Emu rep. who denied any resampling in a 1212/1820 unofficial forum.

I will test this later with DTS WAV file.

Oh so the rolloff is still there? How bad is it when measured with "not-RMAA"? Thanks for showing/telling because I'm also considering the ESI Juli@ which doesn't have the rolloff problem.

My my EMU sticker on top of the EMU10k2? That's gonna get warm and peel off some day eh?

Yeah I'd also like to know how much Guitar Centre can get an EMU0404 for - perhaps I'd get Zemo to ship one to me ...

Edit: What would the Xilinx chip be used for huh?

Rolloff that small is not even noticible. Did you read the rest of the digit-life article?

"We also have results for 1820M, they are published in the RMAA forum. There is the opinion that self-made measurements are absolutely useless and that professional equipment is necessary for tests. To refute this, we're giving tou RMMA test results of a serial E-MU 1820M that were received using Audio Precision 2, a professional measuring station (+4dBu, balance cables):

Test 1820M Line 1/2 AD/DA Loopback RMAA
Frequency response (from 40 Hz to 15 kHz), dB: +0.03, -0.21
Noise level, dB (A): -118.7
Dynamic range, dB (A): 118.5
THD, %: 0.0007
IMD, %: 0.0011
Stereo crosstalk, dB: -118.4

Test 1820M Line 1/2 AD Audio Precision 2
Frequency response (from 20 Hz to 20 kHz), dB: +0.01, -0.05
Noise level, dB (A): -120
Dynamic range, dB (A): 120
THD, %: 0.0003
Stereo crosstalk, dB: -119

As we can see, the results in Noise level and Dynamic range have just a 1.3-1.5dB difference (1 percent). We deem our precision quite appropriate considering that the use of professional equipment costs tens of thousands of US dollars while our expenses have been minimal (in the case of RMMA). Certainly, you won't receive passport data the same way, but one can be quite able to check the announced figures."

Dammit... looks like I need to put my AP2496 on eBay before the resale value drops considerably...
