OH... which AUDIO INTERFACE to buy? lemme see, lemme see..

we have the...

1. the m audio firewire audiophile

2. the m audio firewire 410

3. the edirol ua5 usb

4. the emagic 2|6 usb

5. the emagic 6|2 usb


i need (1) digital inputs (optical preferred, coaxial fine though), (2) 1/4 analog inputs, (3) 24 bit/96hz a/d conversion, (4) xlr inputs would be nice but are not necessary, (5) usb or firewire interface, (6) the highest sound quality i can get for this price range (around $300).


at the moment, i am really trying to decide between the edirol ua5 and the m audio audiophile. it looks like the latter may give me more sound quality, but enough to outweigh getting xlr inputs for $20 less?


any suggestions/insight?


thanks a bunch!
 
Insight:

Are you set on an interface versus a soundcard? Are you using a computer that lacks an available card slot? I mention this only because the most popular option around here seems to be a soundcard--something like the M-Audio audiophile.

Have you done any research into the difference between USB and Firewire in terms of speed, performance, quality, etc.? Firewire traditionally enjoyed a stronger reputation in the past, although USB has come along way.

Are you sure you want to skip XLR inputs? It seems to me that they are crucial if you will be micing vocals, acoustic guitar, etc. I would also make sure that the interface had phantom power to run condenser mics.
 
I'm not familiar with all the specs, but I was sent a 410 to test and review... It was quite nice - Nice sounding converters, etc. Just an all-around handy box. Wish I could've kept it.

And for the most part, if you can keep your converters out of your box, go for it. MUCH quieter when it counts.

in response to the questions that dwillis45 asked:

1. i don't have the option of using a soundcard, unfortunately.

2. in terms of speed, firewire devices are clearly better. speed is not an issue for me, however. in terms of performance and quality, i have not been able to uncover information that indicates whether either port type, alone, affects performance or quality. this is, in part, what i was hoping to learn as a result of my post ...in addition to benefitting from the experience that others may have had with any of the devices i listed.

3. i am honestly not sure if i would like to skip xlr inputs. perhaps you cen lend some insight to this. i have two devices (one analog, one digital) that, themselves, have xlr inputs and which output via 1/4 inch analog and digital (coaxial and optical), respectively. so i had assumed that i could run my mics through either of those without a loss in quality. this assumption may be entirely wrong, however, and i would appreciate any insight into this, as well. (in response to the phantom power comment, i have a separate phantom power box for my condenser mic.)

thanks!
 
massive master, what did you mean by the following statement?

"And for the most part, if you can keep your converters out of your box, go for it. MUCH quieter when it counts."

wouldn't i rather my audio interface perform the d/a conversion for me? i understand that most computers do not perform very well at this.

additionally, at times, i will be running digital inputs into the interface, so d/a conversion would not be an issue in this case. is this a correct assumption?

thanks for your input...

It sounds like you have a preamp with XLR inputs, phantom power, and digital out. This should cover you micing needs and you can run the unit into your new interface, provided the digital connections match (optical>optical or coaxial>coaxial). If your interface also has a mic preamp, however, you will have an additional choice that may give you better or perhaps different sonic results. In addition, having a preamp in the interface will allow you to use a second set of A/D converters. If you rely on your outboard preamp and digital out, the signal will be converted to digital when it reaches the interface. In other words, it should bypass the interface's A/D conversion and be routed to your computer. If you get a preamp/interface combo, the A/D conversion will take place in the interface using a different set of converters. The two sets of converters may be the same or different in terms of quality, but you will at least have some choices. The other issue to consider is clocking. If you link multiple digital devices (preamp w/digital out>interface) you may introduce digital artifacts. I'm not sure if this will happen in your case. Alot depends on how the digital devices relate to one another. Normally, you would have to "slave" one device to the other by setting the interface's software control panel. This normally means that you tell the interface to accept digital signals from the digital preamp or to use the interface's internal clock. At any rate, an interface with a built-in preamp would avoid potential clocking issues.

he meant stand alone AD and DA's i think like these

Or as another example, the Aardvark Q10 incorporates the A/d d/A converter on the soundcard in a shielded case. It's not the best, but quieter and supposedly more efficient than an outboard incorporated converter. Although I'm sure the best would be a solution similiar to that mentioned above.
 
a soundcard is, unfortunately, not an option for me. my understanding is that a usb/firewire interface can provide decent a/d conversion (not concerned with d/a). is this true?

...don't get me wrong. i would love a stand-alone. i just don't have that kind of cash.


so... given my limitations (lack of money, lack of card-slot), what might be my best option?
 
YMMV, but I would go with the M-Audio Firewire 410. If you have a preamp with digital out, try running it through the M-audio and compare. If you want to uprgade your A/D converters at some point down the road, you can upgrade using the M-audio's optical/coaxial connections. For the time being, the built-in converters should qualify as "decent" for the price range. The 410 will also handle D/A conversion which is important since your ability to monitor and mix can be affected by the quality of the D/A conversion process.

I actually meant that almost any audio interface will benefit from the conversion taking place outside of the actual CPU box. There is less chance for interference and electrical noise.

It doesn't need to be a "stand-alone" conversion unit, but if you can convert in a box on your desk and have the digital signal itself just pass to the CPU, the signal will be cleaner than if the conversion took place inside the CPU. 410=external=good.
 
dwillis45, you mentioned that clocking may be an issue.

...i am unfamiliar with this concept, but it seems that you are implying that samples may be 'dropped' in the transfer, which would lead to a degradation in sound quality. is this true? if you don't mind, please expand on this concept and why it's solutions are, uh... solutions.

thanks for all your help!
 
notstuff: Here is a liitle blurb about clocking and wordclocks. I pulled it from the recording glossary at recording.org:

Wordclock - The precise and accurate timing of digital audio samples is critical to the correct operation of interconnected digital audio equipment. The 'metronome' that governs sample timing is called the Word Clock (sometimes conjoined to 'Wordclock', or abbreviated to 'Wclk'). However, word clock does more than merely beat time; it also identifies the start and end of each digital word or sample, and which samples belong to the left or right channels. Digital interfaces such as the AES-EBU and S/PDIF embody clock signals within the data stream, but it is often necessary to convey a discrete word clock between equipment as a square wave signal running at the sampling rate. Dedicated word clock inputs and outputs on digital equipment generally use BNC connectors (the kind of terminals commonly used for video).

You probably won't experience clocking issues unless your studio has multiple digital devices linked together. If you link a preamp with digital out to a hardware interface, you would need to "slave" one to the other by telling the interface to rely on the clock signal coming from the preamp's digital out. This is typically done through a software control panel on your computer. The control panel is normally loaded with the software drivers that come with the interface.

If you have many digital devices, you can get an external wordclock that coordinates all your equipment with a standard, high quality wordclock signal.
