Page 4: Introduction
D/A converters that drive eight balanced 1/4” outputs. Every input on the Tubeopto 8™ 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 and the tube stage can be dialed in for warming effects and soft clipping. -
Page 5: Controls And Jacks
CONTROLS and JACKS FRONT PANEL Instrument Input The 1/4” TS jack on the front panel provides a high impedance unbalanced input, and when used, automatically switches off the mic pre-amp section. (The rear combo jack’s 1/4” TRS balanced input is lower impedance and is part of the mic pre-amp. -
Page 6: V Switches
These switches provide phantom power to each set of four XLR inputs. Use phantom power only when the microphone you are using requires it. Doing so will extend the life of the Tubeopto 8™ as well as reduce the possibility of a shock hazard. -
Page 7: Sample Rate Leds
The ADAT LED will flash if there is no incoming ADAT data, or a data error. This is true for every sample rate mode (not just ADAT). Selecting Wordclock will light the red Wordclock LED and this LED will flash if the Tubeopto 8™ cannot use this input as a sync source. This LED will only flash if Wordclock mode is selected. -
Page 8: Wordclock Input And Thru Jacks
The Wordclock input is used to externally sync the Tubeopto 8™ to a master clock source. The BNC Wordclock Input jack is connected directly to the BNC Wordclock Thru jack, providing the ability to loop through the Tubeopto 8™ and connect other devices to the wordclock sync source, saving the use of a BNC T–adapter. -

Tubeopto 8™ and external gear. One way to determine how this switch should be set is to send audio to the Tubeopto 8™ from an ADAT digital interface and run the audio outputs into a line input on a mixer or signal processor. Check the meters on the mixer or signal processor to see if the level appears to be too high (clipping) or too low (barely showing any indication on the meters). -
Page 10: Using The Wordclock Input
Multiple Tubeopto 8™ units can be daisy-chained by looping the wordclock signal from unit to unit using the Wordclock Input and Thru jacks of each Tubeopto 8™. A single 75 Ohm BNC terminator is placed on the Wordclock Thru jack of the last device in the chain (furthest away from the wordclock generator). -

Alternatively, set the Tubeopto 8™ as master and set it’s sample rate to 44.1KHz or 48KHz and connect the ADAT Output on the Tubeopto 8™ to the Optical In on the Digi unit. In this case you will need to set the ADAT Optical In to be the “clock”... -

ADAT if Wordclock is not available. 7) When using the Tubeopto 8™ as a Preamp-to-ADAT only, if the red Wordclock LED is on solid or either of the green (44.1KHz or 48KHz) LED’s are on then the Preamp, A/D, and ADAT Output sections will be functioning normally. -
