A versatile studio tool that does it all!

The VT-15 Vacuum Tube Recording Channel combines the mic preamp from the D.W. Fearn VT-2, and the DI input functionality of the new VT-3, plus the acclaimed dynamics control of the VT-7 Compressor, and the most-often used features of the VT-4 Equalizer.

Mic Preamp
The mic preamp section has all the features of the VT-1 (the single-channel version of the VT-2), plus a built in Line Pad (the same as our LP-1), and a front-panel 1/4" jack for an instrument input from an electric or electronic guitar or keyboard.

Compressor
The compression section is identical to a single channel of the VT-7 Stereo Compressor, including a switchable high-pass filter in the sidechain to reduce low frequency compression when necessary.

Equalizer
The equalization section is a scaled-down version of the versatile VT-4 LC Equalizer. It has a single frequency for each of the LF Boost, LF Cut, HF Boost, and HF Cut. These frequencies were determined by analyzing which were the most often used settings on the VT-4. Approximate equalization frequencies: LF Boost 100Hz, shelving; LF Cut 90Hz, shelving; HF Boost 9.8kHz, with adjustable Q; HF Cut 11kHz, shelving. The controls are continuously variable, from -12dB of cut to +12dB of boost. The HF Q is also continuously variable.

Which comes first, compression or equalization?
Sometimes you need the compression before the EQ, and sometimes the EQ should come first. The VT-15 does not lock you into only one configuration; a front panel switch allows you to instantly switch from Comp/EQ to EQ/Comp.

A full-size true VU meter monitors either gain reduction or output level. The mic/line input connector is a XLR female, and the output is a XLR male, both on the back panel. The Instrument input is a quarter-inch jack on the front panel. The VT-15 is in a standard rack-mount package, 5.25" high (3RU). A rear panel switch allows the VT-15 to instantly be converted from 120 to 240VAC operation, 50/60Hz.
