The VT-5 equalizer utilizes passive LC circuitry with class-A triode vacuum tube stages for the input and output. The tube circuitry is largely derived from the VT-1/VT-2 mic preamp design, so the equalizer has much the same sonic character as the preamps. The LC-style passive equalization circuitry is based on the classic designs that are still the best-sounding way to achieve high-quality tonal control.

Input Transformer

The input is line-level, transformer balanced-bridging. An active vacuum tube input section has adjustable gain to accommodate input signals as low as -10 dBm. The input transformer is made by Jensen. The output stage utilizes the same custom Jensen transformer used on the VT-1/VT-2 mic preamps.

High-Quality Rotary Switches

All controls are stepped for precise repeatability and uniform matching between units. High-quality rotary switches are used with 1% metal-film resistors. All of the audio capacitors are polystyrene or polypropylene. The inductors are custom-made for us by Jensen Transformers Inc.

Road and Studio Ready

The equalizer is constructed of heavy-gauge aluminum, with a 3RU (5.25 inch), 1/4-inch thick front panel, finished in D.W. Fearn red. It matches the VT-1/VT-2 series of mic preamps in appearance and construction. Like the VT-1/VT-2 preamps, the Equalizer has been designed to provide an exceptional tool for audio professionals. The design frequencies and curves were determined by ear, after extensive listening to a variety of program material, both individual tracks and overall mixes. The result is a highly-musical equalizer with plenty of range for enhancing any track or mix.
