ART TubeOpto 8 Reviews

Incredible bargain

For the price, this is an unbelievable product. The tone is clean and smooth, the conversion is great, the ADAT output is simple, the whole thing is rugged and takes up only 1 rack space. The tone won't change your life or solve all your problems but I haven't found another product that gives you 8 channels for anywhere near this price.

Great add on for a budget studio!

After trying out the tubeopto, I was pleasantly surprised at the clarity and transparency of the pre's. I had thought I would end up with a tube warmth that would color my signal too much, but found that the signal is nicely balanced to keep as much color off of each pre as possible. This was also definitely a plug and play piece of equipment, and i was running audio as soon as I had it out of the box and plugged in via ADAT and a word clock (which had no problems at all). I highly suggest the tubeopto8 as a 8 channel extension for any project or home studio.

High end sound for pocket change

I bought two of these to us for importing and exporting 8 stereo stems from my DAW via ADAT Lite Pipe. The tubes are the icing on the cake. These sound sweet and clean, and are a breeze to operate. The interface is so intuitive than the manual is almost unnecessary. Grab one before ART figures out that they're worth far more than list price.

No direct analog out

I thought this preamp was suitable for MOTU 16A in my portable recorder. It is not because the analog out is not direct out from preamplifier. It goes through A/D and D/A. The sampling rate of ADAT goes only to 48 kHz.

Best value for a tube 8 Preamp!

I wanted to add pre's to my saffire pro 40 and I didn't want the same kind of pre's I already had with my interface. So I went with these tube pre's. I really like them on Drums, they really add a kind of presence, more life to the drums, compared with the pre's on the saffire. For stuff like dialogues or voiceovers I think they are a bit too coloured tho, and the noise floor is quite high. But I really like them on loud sources. I am looking to change the tubes for high quality ECC83 soon to reduce noise floor. This is really cheap and a real good value. They add 8 pre's with one adat cable to my saffire pro 40, so I can carry my rack anywhere and record drums or a full band with 16 inputs. Really versatile. There's also 8 analogue balanced output, which is nice.

Much better than it should be!

I've been running a professional recording studio for nearly 25 years, and have always prided myself on using only expensive, snooty, high-end gear and avoiding anything considered 'pro-sumer'. Last year, against my better judgment, I agreed to do a location recording. It went well and has opened up a new market for me, but toting my expensive, snooty, high-end gear all over town was worrisome. So I decided to delve into that 'lower echelon', and since I'd dabbled with their Tube MP in a classroom setting and felt it was 'good for the money, I settled on the ART TuboOpto 8. But 8 preamps and ADAT A/D for less than half the price of some of my other preamps alone? How good can this possibly be? Well, I was very impressed with the build quality and feel of the controls when the unit arrived, and more importantly, even in my informal tests of the unit before using it on location, was surprised at how nice it sounded. Warm and clear, with definite character. My first gig with it, recording a live jazz ensemble, put it to the test, as I ran all the horns through it. I expected serious problems with both headroom and noise, but the preamps responded beautifully, just as I would expect from an expensive, snooty, high-end piece of gear, none of which this is. Getting the tracks back to my studio where I could really compare them with other similar recordings I had done, I was beyond surprisedshocked, actuallyat how well the audio held up, both from a preamp and a converter standpoint. Because of this I've also added an ART VLA tube compressor to my priority purchase list. I don't plan to give up any of my e-s-h-e stuff anytime soon, but ART has a winner here, and has certainly given me reason to reconsider my life-long aversion to 'pro-sumer' gear.

I'm using Cubase as DAW and Fireface UC . Can I connect Art TubeOpto 8 to Fireface and control/record all to Cubase?
Asked by: Petar
Yes you can. I recommend attaching the Art via the ADAT out optical port to the ADAT in port on the FireFace. That will send all 8 channels digitally to the FireFace for recording into Cubase.

Asked by: Anonymous
The TubeOpto8 is an 8 channel mic preamp. This unit features an optical ADAT digital output that carries all 8 channels. Unfortunately the Focusrite saffire Pro 14 does not have an ADAT input and would not be compatible.

Can this be used in place of a mic activator, such as a cloud lifter ?
Asked by: Nathan
Yes, you can use the TubeOpto instead of a Cloudlifer. The TubeOpto can be used with dynamic and condenser microphones while the Cloudlifter is specifically for use with dynamic mics. The Cloudlifer has a passive design that uses phantom power from the mic input you connecting to and can add up to 25 dB of clean gain. The TubeOpto does much more than just add clean gain since it is fully featured tube-based mic preamp. Its eight channels each have their own input and output gain controls which can add up to 70 dB of clean gain as well as additional features to shape the sound.

question

Is the Art TubeOpto configured for 230 V when it's sent to Europe?
Asked by: Anonymous
I had the Art TubeOpto sent to Australia and it was not configured for 240 V so I am using a power transformer to use it.
