VT-5
Equalizer
From D.W. Fearn:
The VT-5 Vacuum Tube Equalizer will change the way you think of EQ. It is smooth, sweet and very subtle at mild settings, but can also be aggressive when needed. Creative use of the low boost and cut will create a powerful bass that must be heard to be believed. The high boost adds just the right brightness or sparkle to vocals, guitars, keyboards, percussion, strings…you get it. Equally suited for gentle tone contouring as well as extreme sound sculpting, the VT-5 lets your music shine through with no harsh artifacts.
The VT-5 uses passive LC circuitry with class-A triode vacuum tube stages for the input and output. The tube circuitry is largely derived from the designs of the VT series of Microphone Preamplifiers, ensuring that the Equalizer has much the same sonic character as the Preamplifiers. Based on classic designs, the LC-style passive equalization circuitry is still the best-sounding way to achieve high-quality, musical tonal control.
The input is line-level, transformer balanced-bridging and the active vacuum tube input section features adjustable gain to accommodate input signals as low as -10 dBm. The input transformer is custom made to our specifications and is the same model used on the VT-1 and VT-2 Microphone Preamplifiers.
