UTA UTEQ500 3-band Parametric EQ + Shape Control
The most powerful and musical equalizers ever stuffed into the 500 series format. The UTEQ500 packs a huge amount of power into a single 500 series module. Whether you are tracking or mixing.

The EQ incorporates features that have never before been available in a hardware EQ unit. The ability to blend between peak and shelf shape EQs, as well as being able to reverse the phase of a portion of the frequency spectrum, are features that just simply have not been available before.

The UTEQ500 "Shape Control" can literally emulate the shape or slope of any shelf EQ ever created, and it can do an endless number moves that no other EQ has ever been able to do.

we are confident you will find the UTEQ500 to be an indispensable tool in the music making process.

UnderTone Audio MPEQ-1 the amalgamation of the UTA EQ and the custom mic pre of the MPDI-4. It features the same flexible and musical Class A discrete circuitry, the uniquely powerful HP/LP filters, and an exciting new approach to a Class A mic pre.

You can use the equalizer and the mic pre separately or as a complete channel strip. The mic pre has a custom input transformer and a carefully chosen output transformer. Both are optimized to accentuate the most flattering sonic qualities inherent in audio transformers.

The unique mic pre design makes both of these transformers bypass-able. This offers users a choice between the detailed clarity of a Class-A transformer-less design or the vintage musicality of a dual transformer mic preamp.

Undertone Audio Pyra-Sum is a passive summing mixer that has what other summing mixers don't: multiple cascading busses. This bussing architecture allows you to truly have the sound and workflow of a large format console but with even more sonic flexibility and in a much smaller format. We've left out any active circuitry, which means that you have total control of the coloration that's added in the makeup gain stages—it also means you'll need to use this with eight of your own 19" or 500 Series preamps. Want a different sound? Swap the preamps. You could use dedicated preamps for that 70s sound. Tube preamps for that 50s sound.  UTA preamps for a size and musicality that has never existed before.  Or, since the preamps are inserted after each stage of summing, you can mix and match— dedicated preamps on the drums, UTA preamps on the music, and nother type of mic pres on the vocals ... etc. The sonic possibilities are endless.

• Four discrete stereo summing busses
• Recreate the bussing architecture of a large format console
• Incorporate the sound and color of any mic preamps you choose
• All passive circuitry
• Make better use of all your favorite outboard gear
• Make Pyra-Sum the heart of your ultimate hybrid mixing setup

UTA GB Tracker & Satellite are an integrated system that allows you to capture and re-amplify guitar and bass signals with DAW recording setup.

The circuity is designed to maintain absolute sonic transparency as well as unity gain at a variety of detented recording level settings.

The system, with addition of Satellite units, is expandable so you can send a DI signal to as many amps as you want. You can add Satellite units to feed additional amps while maintaining ground isolation between all elements of the system.

The GB Tracker/Satellite system creates a seamless and flexible workflow while recording guitar and bass so you can focus on performances when in the heat of the moment and focus on sounds at any point down the road.

UTA Satellite is the reamping half of the Tracker in its own case, allowing engineers to send the line level signal to an amp in another room, or to daisy chain to multiple amps. The Satellite can also work as a standalone reamping box without the GB Tracker.

Undertone Audio Vari-Cap Instrument Cable
Eric Valentine and Larry Jasper devised a revolutionary solution which allows guitarists to vary the amount of capacitance imparted by the cable, resulting in a MASSIVE influence on the overall tone. It simply allows you to recreate a multitude of sounds from different instrument cables with a single cable.

The VARI-CAP tm essentially liberates a guitarist from just one tone per cable -- aguitarist can now scan through 16 different tones with just one cable. Thought you’d heard every tone your guitar could play? The VARI-CAP offers an adjustment range from 150 pF to 1650 pF and breathes new life between guitars and amps and opens up a whole new spectrum of tonal possibilities.

For passive instruments ONLY. Must be plugged into the instrument.

Undertone Audio MPDI-4 Rack Unit
The MPDI-4 is as musical as it is powerful and flexible. It features 4 individual Mic Preamp/DI circuits housed in a single 1RU chassis.  With by-passable transformers, switchable output headroom, and adjustable THD characteristics, the sound of the MPDI-4 can range from astonishingly pristine to warm, thick, and harmonically colorful. It may well be the only preamp that is truly perfect for every situation!

Undertone Audio UnFairchild 670M II
The Fairchild circuit could be one of the most coveted and time tested compressors of all time. It has proven its extraordinary universal musicality for over 5 decades on countless genres of music. The beauty of its design is in its simplicity. The audio path, primarily consisting of only 2 transformers and 4 paralleled vari-mu tubes, can provide a gentle smoothing of levels or an explosive, energizing compression that will make any recording leap out of the speakers. The UTA UnFairchild is a painstaking recreation of the classic sound of this circuit.
