Vintech X81 Microphone Preamp & Equalizer

The Vintech X81 Microphone Preamp & Equalizer is a dream come true for many an engineer! It features the same celebrated microphone preamplifier as the X73, but with a more comprehensive four band equalizer.

Many engineers love the Class A sound of the Neve 1073, but they always craved the equalizer section of the 1081 which featured TWO mid-frequency bands instead of just the one in most all other Neves. However, the 1081 utilized class AB amplifiers - which is typically a more "even" sounding amp where the eccentricities of the Class A Neve circuits are what most consider to be magical.

The Vintech X81 Microphone Preamp features a class A, all discrete mic preamplifier, but with a more comprehensive four band equalizer with "Q" adjustments on the two mid range frequencies. The Vintech utilizes the same class A amplifier designs found in the Neve 1073 module throughout the Vintech X81 Class A. The equalizer section features ten low mid frequency points, 10 hi mid frequencies, 5 frequecy choices on both the low and high shelving adjustments. There is also a high pass filter, a D.I. and an ouput strength meter.

The Vintech X81 Class A requires the Vintech X73 Power Supply Unit in order to operate. However, one of these power supplies will power up to FOUR Vintech units. By using a separate remote power supply, Vintech units maintain an extremely low noise specification.

What We Think

"Having started out using the 31105 modules in the 8078 consoles, I have personally always favored the Neve 4-band equalizers. I love being able to address the upper-mid frequencies separately from the lower-mid band. They often have very different needs - especially when tracking! The X73 always did it for me sonically, but I always wanted another band when it came to the equalizer. With the Vintech Audio X81 Class A, I have exactly what I want!
