The E27 was created for the need of a high quality modular equalizer. High performance, versatility, ease of use, and simplicity is the initial core of the E27’s design. Some of the best analog gear from the past was the inspiration for its character in sound. Outstanding quality and most suitable parts are used throughout – gold-plated switches, high performance capacitors, high-quality transformers, and custom machined aluminum knobs. Today’s engineers deal with many different types of recording equipment from older high-end analog gear to the newest digitally controlled recording equipment. With this in mind, the E27 can interface easily with many types of gear including balanced or unbalanced sources, high or low impedance loads, even unbalanced loads. The level knob controls up to 16 db’s of cut and boost but for those who only need a few db’s, the travel of the pot starts slow and speeds up at the extremes giving the user more fine control at levels of 6 db’s or less. Knob positions are not only easy to see from a distance but are also felt – the level pot knob has a small point so you know where you are without looking at the eq. The outer frequency control knob has a knurl texture for ease of grip. FEATURES Standard 500 series modular size 1.5″ x 5.25″ 3-bands with 9 selectable frequencies per band ±16 dB of boost and cut using continuous variable potentiometer Push button shelving option for low and high frequencies All discrete design; NO IC chips High headroom Low noise Jensen transformer input & output Custom machined aluminum knobs Gold plated rotary switches and 15-way connector for long life Utilizes 1122 discrete opamps Available as software plug-in by PSP Audioware

The KeyPre® was designed for professional keyboard, synthesizer, and drum machine users who want to use something better than a mixer input channel or a DI (direct injection). Electronic instruments often have a wide range of different output levels and impedances, and with much wider bandwidth than traditional passive instruments such as electric guitars. This presents a challenge for any outboard device following it. A high performance preamplifier, specifically designed for electronic instruments, is needed to ensure nothing is being compromised or bottlenecked as your sound is being processed. Over two years have been dedicated to research, test, and develop the KeyPre® and we are confident it will preserve the integrity of your electronic instrument for both recording and live applications. Features: Six independent channels TRS balanced inputs and output with additional inputs in the front for up to 12 inputs Uses the high performance Ingenius® input stage Direct coupled discrete preamplifier Jensen transformer balanced output Up to 32dB’s of Gain Can be used with either balanced or unbalanced keyboards Supports all variety of electronic keyboard or synthesizer output impedances Very wide frequency response to capture the full bandwidth of your electronic instrument 5 bargraph LED meter which can be custom adjusted internally Internal international power supply Patented Xsolate® Ground Lift System to safely isolate output stage ground connection Designed and manufactured in the U.S. 3 Year Warranty
