OVERVIEW 1

Drive

The DigiTUBE is provided with a DRIVE potentiometer for controlling the amount of signal routed through the 12AX7 vacuum tube. This feature lets you control how much saturation of the signal occurs. Greater levels of tube saturation give the signal greater warmth and a richer sound. This feature works equally well on mics and instruments and is just what is needed to tame that ‘brittle’ sound encountered with different types of digital media.

Internal Clock

An internal clock is provided for 44.1 kHz or 48 kHz operation selectable by way of the switch on the back panel. An INTERNAL/EXTRERNAL selector and a BNC connector for external clock input can be found on the back panel as well as the S/PDIF connector for the DigiTUBE’s digital output.
