Audiofanzine FR's review

Edirol UA-1EX
(Originally written by chguigoz59/translated from Audiofanzine FR)

My main purchase motivations were the 24/96 kHz sample rate and the digital outputs.
Its price tag is very appealing.
I use it with a laptop (Acer Pentium dual-core, 3 GB RAM) running Vista to record vinyl records in 24/96 kHz. I also make music with Logic and FL studio.


It installed itself without a problem and started working right away.
The user's manual is ok. The setting is very easy.


The driver works fine. It's better to disable all other USB devices (if possible) when you use the unit to avoid any problems.
It is also wise to configure Windows so that it gives priority to background tasks and to disable all graphic effects, etc. especially if you are running Vista, otherwise you might have some unpleasant surprises and clicks.

I use it mainly with Cool Edit, Logic, Wavelab, FL.
The lowest latency with Logic is 9 ms, which is barely ok for real-time applications. Once you try to reduce this value you'll start to have serious problems.


I've been using it for 3 months.
I don't like the fact that you have to set the sampling rate before you turn on the computer or plug the audio interface. Therefore you also have to disconnect the unit to change its sample rate.
Furthermore, if you want to work at 24/96 you must choose between either play or rec mode!!
That means that if you record something at 24/96, you cannot play it back immediately. You have to close the software, disconnect the audio interface, switch the jumper to the play position and relaunch the software!!!

The analog RCA input is bridged with the mic input and there is no input selector nor a separate control for each, so if you want to record a high level signal you get tons of noise, even without a mic. Hence it is important to set the level of the source correctly for recording. You have a knob to set the level.

The recording and playback quality is rather good. The RCA outputs deliver a good sound definition, especially at 96 kHz where the soundcard really excels. The sound of the headphone output is very bad, especially at loud volumes, the signal has no dynamics and you can hear distortion in the low-mid range. The output of my Acer laptop sounds much better!! They advertise the soundcard emphasizing its sound quality and proclaiming that it allows you to enhance the poor audio capabilities of the laptop's integrated soundcard... rubbish...

Its ok for the money, but choose another product if you have the means to do so.
I wouldn't buy it again, although it's ok to record high-level sources.
The audio interface is quite comprehensive and it is one of the few models in this price range that provides digital inputs and outputs.

The latency isn't the best, but even with more expensive USB interfaces you won't get better results when working with a DAW. Go with a Firewire for that.

I use it to get in and out of my digital laptop


No pb installation, including windows mdia edition ...
very complete, very simple config manual


The driver works well with cubase and Audacity anyway (ASIO)
latency is less audible but the sound card of the PC


I just bought it for the price frankly, it's very good!
(I'm happy with being able to get in and out 24Bits.)
Regret is the optical minijack the toslink would have been more convenient.

Puzzle100's review (This content has been automatically translated from French)

Edirol UA-1EX
Domestic use on my desktop or my weekend in partable
Setup an old chipset P4M 845 (mobile) and C2C on CM ASROCK (VIA)
Used with Oxygen 8 keyboard, or my old Roland PC200.


Installation without any worries, no conflict detected.


I do not use the ASIO4ALL drivers EDIROL friends rather that give better latency (13 ms)
This latency is not great compared to the results that I read for other sound cards, but me, it does not bother me (the 200 ms of the sound card integrated with the CM bothered me more)


Used for 3 weeks
The only thing a little heavy is the optical output is also a 3.5mm jack is a standard limit and the optical cable connection jack -> Toslink costs half the price of the sound card!
Plastic and assembly are really Camelott, but for 89 EUR ...

I remake the same choice again.

gabzor's review (This content has been automatically translated from French)

Edirol UA-1EX
CHARACTERISTICS The choices that led to my conversion rates n / a deus 24b/96Khz in meaning as well as RCA or optical connectors.
I don 't serve with computer music (Korg + Fruity, Samplitude, etc ...)

My config: Celeron M 1.5 Ghz mobility, 512 MB of RAM.


For the installation, if we know a little computing c 'is very simple.
Simply insrer the CD, install drivers, plug the card and then select the drivers adequate locurence home Edirol UA 1EX: it is like pork salvation that is written on it;)
The manual is in English but of logic and some basics to know enough not to plug in the out and back in but if you plant anything I can for you 0_o
Gnrale configuration could not be simpler panel gnral regoupe while in 2 or 3 options trs simple matriser
Everything is set up directly on the card (chantillonage, etc.)


Impossibility to open and fruity samplitude while at the same time or with the AC'97 drivers
I don 'records no actual instruments for now but I would soon and I' updater
9 ms of latency with the default buffer size less than half


I use it for 12 hours.
What I like least: impossibility to open several software drivers using the card but it must be able to rsoudre.
What I like most: 24b/96khz with 9 ms of latency on an intuitive interface trs.

To use that I 'did (electronic music)' s effective trs. Very practical for monitoring and recording simultaneously correct quality trs.

J register with Harmand kardon amp via the analog numrique as a warrior and I can 'one rsultat I don' t dare call
L even if the purists will say it is better q'il are billions of possibilities that s' open with such a tool in my configuration.
I hsiter remake that choice without a second.
