Product Description

The UA-25 is a powerful USB Audio/MIDI interface designed to offer premium sound quality, rugged durability, and complete portability for computer-based audio engineers. The UA-25 is compact enough to travel anywhere you can take your computer. The UA-25 is constructed of high-grade aluminum for the chassis; it can withstand hard impacts that are normally associated with traveling or working in the field, and the aluminum is an excellent shield against high-frequency interference from other electrical components. The UA-25 is USB powered, so you never have to plug it into a wall socket, but it can still power condenser microphones with its 48V phantom power. The seasoned audio professional will love the UA-25 for its ability to output audio at +4dBu from the balanced 1/4" outputs, making it the best portable audio interface to shuttle between the field and the studio.
Premium Audio Quality
The UA-25 uses powerful analog electronics coupled with well-matched A/D & D/A converters for superior audio fidelity.
Feature List
- Solid Metal Construction
The UA-25 hosts Edirol's latest audio technology in a small, durable body for incredibly portable USB audio recording. - Variety of Input & Output options
The UA-25 includes a pair of Neutrik XLR/TRS combo inputs with Phantom power, Hi-Z (Guitar) connection, S/P DIF optical I/O, analog outputs, 1/4" headphone output, and MIDI I/O. - Balanced Input & Output
With an integrated low-noise, wide-range power supply, the UA-25 can be bus-powered with balanced audio inputs & outputs for professional quality. - Two Professional Grade Mic Preamps
The UA-25 is a completely portable recording center with very clean, high-gain microphone preamps & premium analog components perfect for home studio & field recording. - Built-in Analog Limiter
Reduce sudden overloaded sounds or popping noises in your recordings. You can often get overloaded levels while recording on the fly. With this switch set, you can still achieve a high-quality sound while retaining a wide dynamic range. The side diagram shows the Limiter characteristics. - Zero-Latency, Direct Monitoring
The UA-25 provides ultra low latency with maximum performance from popular music software such as Sonar, Logic, and Cubase. You can control Direct Monitoring from the front panel, not only for ASIO 2.0-compatible applications but also for others. Ideal for soft synths controlled from MIDI devices. - Powerful Low-Latency Driver Performance with WDM, ASIO2.0, & CoreAudio Support
The UA-25 comes with WDM, ASIO2.0, & CoreAudio drivers for low latency with most audio applications. The UA-25 can also use the OS-standard driver, using the ADV switch. Sound Manager for audio and OMS/FreeMIDI compatible on Mac OS 9 and Windows98 and Me as well. - USB Bus-Powered
No AC adaptor required! Just connect one USB cable to your laptop to create a Pro-quality field recorder. Reduce your cables, record anywhere with the UA-25.

good entry-level unit,

This review is from: Edirol UA-25 USB Audio Interface (Electronics)
I recently got into digital/software recording, and was looking for an audio capture interface to perform tracking using PC software. Edirol UA-25 was an impulse buy for me, but for the most part, it paid off.
There are many features provided on with the interface. While the 24bit/96kHz I/O advertisement is misleading, tracking in 24-bit at 44.1kHz presents relatively few problems and the sound quality is acceptable. In addition, the digital I/O allows uncompressed PCM stereo to be sent directly to recording software, allowing zero-latency recording (meaning, you will only have latency from your software, not from the unit). However, direct monitoring will be disabled if you plug in digital input (so you'll be forced to use software echo to monitor from your PC). There are several (relatively) minor drawbacks. First, only one of the analog inputs provides a Hi-Z switch, meaning that you either have to use a direct box or two Lo-Z inputs to record a stereo signal or two audio sources. Not a big deal for me (I record digital signal from my floor processor), but annoying enough if you want to get into more sophisticated functions. The hardware limiter, which applies light compression to the analog signal, is less than it's made out to be. An instrument-level guitar signal will be too soft playing single notes, but playing full chords will cause clipping even when the limiter is enabled. Because you can't define the parameters of the compression, you still have to reset the input trim for different parts of the song. Again, not a major issue, but leaves more to be desired. Finally, the unit operates in 24-bit exclusively. On one hand, that seems like a positive feature. However, you must remember that having a 16-bit soundcard in addition to the UA-25 may prevent your software from operating in 24-bit due to compatibility issues. Using an old SoundBlaster Live Value, I ran into numerous bitrate conversion and dithering issues that cause nasty "digital noise" which sounds like clicks of a CD skipping. Make sure your other hardware is capable of 24-bit processing, before adding a UA-25 to your system - otherwise you may have to disable it. The unit is USB-1, not a later version. This is more than enough to process two analog inputs and two-way MIDI in real-time, but again I ran into compatibility issues. The unit uses USB power exclusively, so having other USB-powered devices might cause less-than-perfect operating conditions. I bought a USB 2.0 4-port self-powered hub to deal with this issue, but unfortunately UA-25 produced loud, distorted, noisy signal when plugged into it. I'm guessing that happens due to legacy USB configuration, as none of my other USB devices had comparable problems. Overall, I don't regret getting the UA-25. It allows me to do what I need to do - record a stereo guitar signal, either analog or digital. It'll also allow vocal recording when I get around to it, plus I can record direct instrument straight into my software. However, I highly recommend examining the market for alternatives to deal with the problems I presented above.

New Software Issue,

This review is from: Edirol UA-25 USB Audio Interface (Electronics)
Just was told by their great toll free customer service that the problem I'm having is not something they intend to fix via driver update since they can't (!) and it's a Microsoft problem, namely the device started to no longer allow full volume turn down when I updated to the official Win XP SP3 version from my old SP2 version. Google searches of forums are proving useless, especially since SP3 was only released a month ago, in Sept. of '08. Roland/Edirol claims this is an "known issue" with SP3, and also claims most of their customers "steer away from Windows" and build their own computers from parts and in a friendly tone arrogantly told me they were not much concerned with the problem. It's just frustrating. Lots of utilities exist as third party software volume controls, which I will have to try a few of, but I prefer the physical knob on this otherwise wonderful little box that indeed runs power hungry microphones quite well, though I haven't checked those under SP3 yet either.

Saved Me Thousands...,
By the.EXaMinEd.LivInG.Pr0jeCT. "Coming Soon" (S0meWhere) - See all my reviews
This review is from: Edirol UA-25 USB Audio Interface (Electronics)
I have Windows XP Media Center on my HP Pavilion dv6130us. As I was looking to buy a Digital Audio Interface, I discovered that many of them were unable to work with Windows Media Center. I searched the web forever, and finally settled on a Mackie Firewire product. After getting it, I discovered that the Firewire port on my computer was no longer functional, and I spent another day searching the web. Finally after finding one person (out of about 10,000 searches) that said they were able to get Edirol to function with Windows Media Center, I decided to risk it, and buy the product. IT WORKS BRILLIANTLY. Less bulky than the Mackie. I hadn't been able to get Asio 4all to work with my existing audio software (Mixcraft 4), and the Asio drivers with the Edirol work perfectly, and I always have low latency. High quality 24/96 audio input and output that provides clear, crisp high definition sound. I have yet to connect it with my MPD16, and I'm excited to do so. This is exponentially better than my already capable Conexant High Definition Audio on a 945gm Intel chipset, and that records up to 24/192....If you have Windows Media Center, I can't guarantee it will work, because I don't know the technical details behind the Windows Media Center problems, but, hey, I'm at least the second persons who's got it work, and it works brilliantly.
