The Vintech X73 is a class A, all discrete, transformer balanced microphone preamplifier with equalizer. It is built with the same circuit design and components as the classic Neve 1073 module
Our new “X81 Class A” features the same great microphone preamplifier as our X73, but with a more comprehensive four band equalizer with “Q” adjustments on the two mid range frequencies. We utilize the same class A amplifier designs found in the Neve 1073 module throughout our 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 Universal Audio 2-610 is based on the legendary Universal Audio 610 modular console. Designed by Bill Putnam, the Universal Audio 610 was among the first modular recording consoles. Early Universal Audio consoles were used in all of Putnam’s studios including Universal Recording in Chicago and United/Western in Los Angeles. Many prominent engineers such as Bruce Swedien began their careers in these studios with this classic rotary knob console. The 610 was particularly well noted for its preamplifier, and has left its mark on countless classic recordings from Frank Sinatra to Van Halen, to the seminal Brian Wilson recording, Pet Sounds.

Using the same circuit topology as the original ISA microphone pre-amplifier designs, the Red 1 offers four channels of ultra-high quality Focusrite microphone amplification. Used with high quality ribbon, valve and condensor mics, the Red 1 obtains outstanding results with any sound source, but especially voice, piano and string instruments.
With four mic pre-amps in a single unit, the Red 1 is ideal for those looking for improved audio performance, as a compact ‘way in’ to digital recording systems, or for location multi-mic recordings. Each channel offers custom-wound Focusrite input transformers, switchable phantom power, phase reverse, an easily-read illuminated VU meter, and a handy scribble disc for denoting channels. Mic gain is switched in 6dB steps over a 66dB range, for accurate, precise channel matching and recall.
The output stages of both the Red 1, with its custom transformer, will easily drive very long cable runs – up to several kilometers – without significant loss of quality, making them ideal for remote recordings.
- Hand-made in the UK
Crafted to the highest standards, all the Red Processors are manufactured solely in the UK using machine-tooled, half-inch thick claret red anodised aluminium. - Classic transformer-based pre-amp
The benefits of Focusrite’s classic pre-amp topology include superb common-mode rejection, an excellent overload margin, an extremely low noise floor and super-wide bandwidth. - Phase Reverse and Phantom Power
Available independently on each channel via firm-response illuminated switches - VU output level meter
Four easily-read illuminated porthole window VUs are provided. - Scriblle discs
Four handy scribble discs for denoting each channel - Stepped gain potentiometers
Mic gain is switched in 6dB steps over a 66dB range, for accurate, precise channel matching and recall.
