Review: Edirol UA-25 24-bit 96kHz 2in 2out USB soundcard

I’ve become quite a fan of this sound device since I got it about a year ago.

For its price, the sound quality is excellent. It’s fairly packed with features, has a good range of options for input and output connectivity, plus MIDI. And it works flawlessly, out of the box, with Linux — no special setup or drivers required, ALSA knows what it is and how to deal with it in any mode.

The same is true of Mac OS, but only in the basic mode which restricts you to 16-bit 44.1kHz I/O – a driver is required for Advance mode to get up to 24-bit 96kHz support (either in, or out – we’ll come to this under Limitations). This driver can be downloaded free from the Edirol website, and seems to work fine on my new unibody Macbook Pro with OSX 10.6 Snow Leopard, though I haven’t used it extensively on there yet.

I guess it probably works in Windows too, but I wouldn’t know anything about that 🙂

The sound quality (for what I’ve used it for anyway) is very good. It’s stacked with features, and quite versatile… within certain limits.

First we’ll take a quick look at the features packed into this gadget, which is information you could probably find elsewhere but I include for ease of reference, and after that we’ll get to discussing those limitations in more detail.
