TubeOpto 8, an excellent addition to the O1v

by Robert Cross from Virginia Beach, VA

Music Background: Live Sound Engineer
Great sound quality, ease of use, light-pipe connectivity, front controls and metering and the clients like the fact it has tubes for warmth.

In addition to opening up channels 17-24 ... read more [+]on the input side, I now have 8 outs I can send to 4 stereo or 8 mono headphones or wedges.

The O1v is a great tool, the TubeOpto 8 expands the users options.

When I get the cash, I plan to add another, expanding my live rig to 32 channels. After extensive research, I cannot imagine a better quality sound, ease of use and more bang for your buck than the TubeOpto/O1v combination. close [-]

Great Sound, only these knobs....

by Dominic Dot Okune from Mississauga, Ontario, Canada

Great piece of equipment, sounds really nice, when tubes are not pushed hard. Needs a bit fiddling in and out to get desired sound and levels. I use it with Focusrite Saffire 56, i wanted to get octop... read more [+]re but went with art, no regrets at all. Sound quality very close (if not better) to Saffire 56. All that great BUT... these knobs, horrible choice for knobs, they feel cheap, they dont move smooth, but simple solution.. ebay and order yourself a set of new knobs. SSL style knobs work perfectly, way better than stock ones. No friction at all. RUNS HOT keep it in mind. Soon i'll try changing tubes in mine. close [-]

Nice Features, Runs Hotter Than Expected

by Daniel "Danny" Maland from Salt Lake City, UT, USA

Music Background: Live Sound Engineer, Recording Engineer
I definitely like all the features included on the front panel, like the mini-meters, PAD switches, and high pass filters. I do find myself wishing for click stops on the knobs (but then again, what h... read more [+]as that other than multi-thousand-dollar units that say "Mastering" on the marketing literature), and I was also surprised by how much thermal radiation the tubes emit. (To be fair, I'm not really a follower of tube-based equipment, so I have no reference point.) close [-]

Great for Drum Tracking

by Marty from Fort Worth, Texas, USA
August 9, 2010
Music Background: Recording Engineer
Bought one of the first ones. Hooked up the ADAT out to a RME RayDAT and tracked some rock drums on Nuendo. Result: punchy, low noise, handles transients well, slight bit of upper harmonic warmth (tub... read more [+]e saturation). Then I took the ADAT out and plugged into the ADAT in and used the analog outs into my hot-rodded Soundcraft Ghost (Burr-Brown op amps, low ESR caps) and then to a Lynx Aurora and Nuendo. Result: more analog sounding, better midrange, even better soft clipping in the upper harmonics. Bottom line--with the right digital interface, a good alternative to an op-amp based preamp box. The tubes are Chinese 12AX7s (total of 4 stereo), but definitely not bottom of the barrel. Some amount of hand-picking obviously goes into the tube selection at assembly time. close [-]

I love the personalized service from Sweetwater! I buy almost all of my musical equipment from you. That way, my rep knows exactly what I'm working with and can therefore anticipate my needs in many ways.
