AVALON – V55 Stereo Preamp

Descrizione

“The Avalon V55 is a dual channel, Pure Class A Microphone Preamplifier, DI Instrument preamp and features transformer isolated outputs for RE-AMPING. The V55 will capture every magical performance and continues Avalon’s passion and commitment to SONIC EXCELLENCE while delivering deep and controlled bass, musical midrange for enhanced vocal projection and ultra high impedence “transparent” instrument inputs.“

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 V5 includes the best of the Avalon U5 DI functions with a studio quality preamplifier 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 V5 with a new scale of sonic character.

AVALON V55 FEATURES:

• 2 V5 preamplifier/direct box/re-amping units in a single chassis rack kit
• Amazing all-in-one microphone preamplifier, DI, and re-amping box
• Top-shelf parts using all-discrete, high-voltage, Class A components for pristine sound
• Dual hi-Z and lo-Z microphone inputs accommodate anything from low-output ribbons to high-output condenser mics
• 10-Megaohms direct instrument input with zero impedance loading accommodates any instrument with active or passive pickups
• Transformer-isolated re-amping output lets you send signal back to an external guitar amp for re-amping
• Passive Tone Shaper provides 10 tone presets (including 2 Air-Lift vocal settings)
• 6 Tone Shaper settings adopted from the Avalon U5
• Built-in lowpass filter and buzz/hum filter ensure the cleanest possible sound
• Large VU meter provides easy and accurate monitoring

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.
