About Art Pro Audio TubeOpto 8

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. ADAT lightpipe I/O handles eight channels of 24-bit audio input and output at either 44.1 or 48 kHz sample rates. Wordclock in and thru-puts allow multiple Tubeopto8's to be synced in complex system configurations.
