The VT-series microphone preamplifiers will change the way you think of audio quality. The transparency is astounding. Vocals sound smoother, warmer, more intimate, with a compelling presence. Any microphone and any sound will benefit from the improved clarity, definition, and lack of solid-state artifacts.

The VT-1 recreates the sound of classic tube preamps of the 1960s. Modern components and computer-optimized circuitry, unavailable during the vacuum tube era, elevate this design to a new level of performance.

Design Philosophy In designing the VT-1, no compromise in sonic quality, reliability, or ruggedness were permitted. Like the best tube equipment of the 1950s and '60s, the VT-1 is built on a heavy-gauge aluminum chassis, utilizing point-to-point wiring. Each vacuum tube is selected for minimum noise and microphonics, and maximum sonic clarity. The front panel switches control sealed, gold-contact precision relays for all audio switching, eliminating the possibility of dirty contacts degrading the sound and minimizing the internal audio path. Four class-A triode amplifier sections (in two tubes) comprise the entire active circuit. This surprisingly simple circuit, along with top-quality components and careful design optimization, results in the sonic superiority that the VT-1 has become known for.

All over the globe, VT-1 preamps are in daily use in the world's best studios, as well as in home project studios, helping many top recording artists achieve the best possible sound.
