Demeter VTDB-2 Single Channel Tube Direct Box

The VTDB-2B is an AC-powered direct box with a single 12AX7 tube and a Jensen JT-DB-E transformer in the audio circuit. In addition to typical direct-inject functions, the unit can be used for warming up synthesizers and alleviating digital harshness on any recorded signal.

Operating at a higher-than-normal level of impedance, the VTDB-2B delivers a strong low-impedance signal. This extra headroom means that a performer can play with a wide dynamic range without overloading the system or creating distortion. The high-impedance output signal also gets an extra boost from the 12AX7 tube. It acts like a pre-preamplifier, adding noticeable clarity to the sound. The boost switch increases the low-impedance output by 15dB, which is useful when the input signal is a little weak or when that extra punch is required.

A buffered loop through output can be used as a line driver (at unity gain) for long cable runs or multiple stomp box layouts. A boost switch selects -20 dB or -4 dB at the XLR output, and a ground lift switch unearths pin 1. It comes with a 1/4" phone input and balanced XLR output along with a loop-through 1/4" phone output. The VTDB-2B must be plugged into an AC outlet rather than using battery or phantom power from a mixing board.
