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.
- Mono tube direct box
- Acoustic Guitar
- The extremely high impedance of the Tube Direct insures a perfect match with every pickup to provide a warmer, more natural sound-both live and in the studio
- Electric Guitar
- Provides a clear, warm sound that retains all of the guitar's natural brilliance and harmonics for creating a viable direct sound with or without additional signal processing
- Warms up the sound of the synthesizer and provides an ideal interface for the variety of synthesizer output levels and impedances
- The clarity and sheen of digital and hard disk recording can sometimes seem a little harsh or more brittle than desired. Use of the Tube Direct can often mitigate this problem at several points in the recording chain, including mixdown
- Ground lift switch eliminates typical ground loop problems
- XLR balanced output
