VT-7

From D.W. Fearn:

Ideal for tracking, mixing and mastering, the VT-7 features an all Class-A vacuum tube audio path, like all D.W. Fearn products. The gain reduction elements utilize circuitry that duplicates the sound and characteristics of the finest classic vacuum tube compressors, without depending on esoteric tubes that are no longer manufactured, while the Pulse Width Modulation (PWM) control circuitry is modern solid-state analog.

Designed to deliver a highly transparent sound, the VT-7 can be used more aggressively if desired, with artifacts of the compression process substantially diminished when compared to most other compressors.

In use, the two channels may be used independently or linked for stereo, while a third position on the Link switch inserts a high-pass filter (HPF) in the side-chain to reduce the gain-reduction sensitivity of the VT-7 to low frequencies. This is a gentle roll-off, nominally at 100Hz, allowing a bass-heavy mix to have a better frequency balance and avoids heavy low-frequency audio from modulating the audio level.
