Forum : Producing Help : new audio interface

hi all!
i'm upgrading my system and will be working on mac soon. i don't know shit about audio interfaces, so i'd like some help...
my eye fell on the Apogee ONE interface (http://www.apogeedigital.com/products/one-features.php), as it has a slick design and superb quality (according to the reviews...). i know it's supposed to be a portable solution, but it has all that i need (i think). BUT it only has one 1/8" stereo output for unbalanced speakers.
--> 2 questions here:
*is it okay to connect 1/4" monitors through a splitting device connected to the 1/8" output on the audio interface? will that lead to quality loss?
*why unbalanced cables? quality loss?
Then i saw the Apogee Duet, which is more expensive, but has a breakout cable that provides 2 1/4" monitor-outputs, also unbalanced.
So, as far as I knew it's always better to make balanced connections or through XLR, so i don't really understand why they used unbalanced outputs on the Apogees... Is that standard for monitors or something?
Anyway, if you have the answer to my questions, please reply :)
Suggestions for other audio devices are also welcome (my budget is around 3-400 euro, but preferably less as i only need a mic-, guitar-, monitor- input/output
Also another question: do i need to plug my (usb-)midikeyboard into the device or directly into the computer?
greets from a hardware-noob

i've got the Edirol UA-25Ex :) http://www.rolandus.com/products/productdetails.php?ProductId=970
It's affordable (€195 in keymusic) and i'm very pleased with it :)

interesting do you use mac or pc, and if pc do you use the 64bit or the 32bit os?

same as antares :)
 
 
 
hi 
we use the apogee duet & must say the quality is outstanding ; top gear!
the only difference between this & pro gear is indeed the balanced/unbalanced outputs
(the inputs r balanced)
in fact, when u send them directly to powered speakers, this is not a problem at all & intended
u will c that the inputs on yr speakers (can) match the output voltage of this apogee (-10dBv)..
remember : dBu=dBv 
grtz,
jay
ps. don't understand yr first question : will u split the 2 outputs into 4 (speakerz) ? or will u convert the 1/4" jack 2 1/8" (mini)jack  ??

hmm.. not quite... dBu is for professional
use, with 1volt as reference, while dBv is for consumer use, with 0,775
volt as reference.
  
Quote:
that's why on many powered speakers, you'll have the choise between -10dBv and +4dBu as input reference
 
as for the apogee, off copurse you can split from one stereo 1/8" to 2 mono 1/4", but you should use good shielded cables, since unbalanced connections pick up much noise.

Doin the same lately ;)
saw that Apogee aswell and wuz intrigued by it, but i think i fell in love with this good lookin:

lookin forwart to yer revieuw
 
 
 
tiens,
1 dBu = the voltage level wich delivers 1mW of power in a 600 ohm resistor
it is a reference of an RMS measurement (of voltage)
the reference = 0.775 V (RMS)
= 1dBv
u = unloaded
v= volt 
1dBV = the voltage relative to 1 volt , regardless of impedance
look 4 t difference...

Hi everybody !
This topic is perfect because it s my birthday tomorrow so i hope i ll get the money that miss me to get an audio interface. And actually i was lookin for the cheapest one ( but still with good performances ). The edirol ua-25ex seems nice but i aked myself if somebody knew something else in the same prices and competent too...
je continue les recherches :D
thank you

srry, mixed up between 1V and 0.775, but i did mean dBV; on consumer it is -10dBV (not dBv)
