Avalon V55

Classe A pura, preamplificatore microfonico, DI e RE-AMP

Avalon DI-preamplifiers have been in use around the world since 1985. They have found their way into the world's leading musicians rigs and recording sessions and have been featured on thousands of the best selling (and sounding) albums, downloads and live performances. The V55 includes the best of the Avalon U5 DI functions with two studio quality preamplifiers and "a new sonic addition". Two alternate solid-state topologies are cascaded to provide a rich, low midrange harmonic content not offered in other Avalon preamplifiers. This feature empowers the V55 with a new scale of sonic character.

SONIC EXCELLENCE

The Avalon V55 DI-RE-MIC Preamplifer is an ultra-high performance professional dual channel preamplifier, DI and RE-amper. Created for maximum versatility, the V55's sonic signature - "Deep and Controlled Bass, Musical Mid-range and enhanced Vocal Projection" combine with a unique set of user features including, 100% discrete Pure Class A amplification, Avalon's unique "passive" TONE-BANK™, professional VU meter with dual peak LED's, multiple outputs including an instrument level transformer isolated Re-amp. Designed to optimize absolute signal integrity and musical performance, the V55 is ideal for ribbon, dynamic and condenser microphones, bass guitar, acoustic instruments, electric guitars, keyboards, synthesizers, and very low output passive pickups. The state-of-the-art DI input stage provides a very-high inpedance, "zero-load" effect on sensitive pickups and keyboards, while maintaining massive input headroom to +36dB before overload.

MINIMUM SIGNAL PATH DESIGN

The V55 includes a very high quality input transformer (same as the Avalon VT-737sp) with dual microphone input impedance loading for perfect mic/cable matching, high-cut switch for eliminating unwanted acoustic pickup and high frequency noise, headphone monitor amp and DC coupled, 100% Class A output amplifiers for defined bass control. A buffered "thru" output for zero-instrument-load tuners or power amp inputs, internal toroid power transformer with discrete high-voltage power supplies for low noise and sealed silver relays for transparent signal routing.
