OVERVIEW

High-input, single-channel DI-preamp for professionals.

Avalon' U5 is a high-voltage DI-preamp that combines a unique, passive tone selector with a variable gain preamp and filter. The high input impedance accepts a wide variety of signal levels and instruments from acoustic guitars to high-output active bass guitars and keyboards. The U5 direct box is loaded with sonic character and the features that professional users demand.

Sonic Excellence
Designed to optimize absolute signal integrity and musical performance, the U5 includes many professional features including state-of-the-art, high input impedance input stage for zero load effect on sensitive pickups and keyboards, 100% discrete, Pure Class A signal amplifiers, practical user features and rugged hardware that' designed to deliver high performance audio for many years. The U5 is ideally suited for bass guitar, acoustic instruments, electric guitars, keyboards, synthesizers and low output pickups.

Designed For Deep and Controlled Bass
Avalon U5 DI-preamps have been in use around the world since 1995. They have found their way into the world's leading musicians rigs and recording sessions and been featured on thousands of top selling (and sounding) albums and live performances.

Minimum Signal Path Design
The U5 includes a variable gain Class A preamplifier to boost low level pickup signals and a high level speaker input for capturing the live sound of the instruments amplifier. Six passive tone-EQ curves are also included to enhance a variety of acoustic and electric instruments. A high-cut switch eliminates unwanted acoustic pickup and high frequency noise, while a headphone monitor amp has been included for personal listening. Twin DC coupled Class A output amplifiers drive both low level microphone preamp inputs and high level +4dB inputs for direct to tape recording or processing. The active-to-thru switch selects either the instrument input directly or sends the boosted-equalized signal to the amplifier via the front panel jack. A ground isolation switch eliminates any possible earth loop or AC buzz problems with complete safety.
