The ART TubeOpto 8 is the ideal Eight Channel input / output expander for any ADAT lightpipe equipped audio interface, direct-to-disc recorder or DAW. Eight high quality second generation discrete Class-A vacuum tube microphone preamps are packaged in a single rack space unit with eight channel 24-bit digital I/O.

Every input on the TubeOpto8 offers full control of the signal path with pad, phase and low frequency roll-off switches. Input gain and variable output level control of each channel allows up to 70dB of clean gain with incredible sonic transparency or for the tube stage to be dialed in for warming effects and soft clipping. Each channel has wide range LED meters monitor the preamp output levels while clip indicators monitor mic-preamp peak levels.

Got this for tracking drums too. Some of my mics were running really hot, so the pads and the output level are really good features. Sounds clean and doesn't add a load of color. Happy I got it. Would recommend to anyone looking for an affordable preamp with good build quality.

Got this for tracking drums and limited rack space... absolutely great piece of gear. Loads of options. Very clean sounding. No real colour, but for the price, can't complain. Well worth the money!

Great unit, very well built, the only "cheap" part of it are knobs. They feel horrible and not smooth at all, however there's a fix for it. Ordering new knobs f.e. SSL style will fix it. Other than that everything else is great.
