The Electronic Tube Direct Injection is a high voltage tube driven DI with an optional mono output, also driven by the tube at unity gain. The ETDI uses a NOS Sylvannia 5963, which is a ruggedized version of a 12AU7. The tube can handle signal strengths all the way up to line level, which allows it to be placed in the effects loop of an amp...perfect for warming up a solid state amplifier and simultaneously providing the signal to a mixing board via a transformer coupled balanced output. Additionally, the Thru jack provides an unaffected signal that is in parallel to your input in case you want to send your clean signal to the input of an amplifier.
The internal power supply has been designed such that any noise present is minimized due to a push-pull topology. As a result, the output signal has extremely low noise.
The ground lift switch connects Pin 1 of the XLR to the chassis when pressed in, and disconnects when the switch is depressed.
A 12VDC power supply is included with the ETDI. The ETDI requires 12VDC (do not use any other voltage), and at least 300mA.
To ensure maximum tube life, remove power from the ETDI when not in use.
