D-TuBe 8 Channel Valve Mic Input Card

The D-TuBe provides eight channels of tube pre amp. It has been designed to fit neatly into existing DiGiCo systems by simply replacing the last input module on a stage rack and moving the output module along by one slot. This keeps the full complement of 56 inputs to the stage rack, with the last eight inputs now being TuBes.

Operation of the D-TuBe is exactly the same as a standard Mic Input card.

When a D-TuBe input is selected as a source for an input channel, analogue gain and digital trim controls will be shown at the top of the input channels.

The analogue gain control is pre valve and can therefore be used to "drive" the valve. The digital trim control is post valve and can therefore be used to adjust the resulting output level from the valve.
