DESIGNED FOR DEEP & 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 the best 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.
