SVTDI Vacuum Tube Direct Injection

Introducton to the Ampeg SVTDI:

The harmonically rich sound and legendary performance of AMPEG products are redefined in the SVTDI. This Vacuum Tube Direct Injection device delivers unsurpassed quality, reliability and tonal flexibility in a compact, rock-solid package with exceptionally high cosmetic appeal. The SVTDI is easy to operate and is well suited for live performances or for use in the recording studio. Acoustic and electric instruments will benefit from use of the SVTDI.

The SVTDI Vacuum Tube Direct Injection can take an unbalanced line level signal (bass, guitar, keyboard, etc.) and convert it into a balanced signal which can be sent through a long snake to that mixing board so far from the stage - without degradation of the signal! The SVTDI offers direct or tube-buffered 1/4” and XLR output connections, and has a switchable 6dB input attenuator to handle “hot” signals.
