Avalon DI preamplifiers have been in use worldwide since 1985. They’ve found their way into the rigs and recording sessions of the world’s leading musicians and can be heard on thousands of the best-selling (and best-sounding) albums, downloads and live performances. The V55 incorporates the best of the Avalon U5 DI features with a studio-quality preamp and a new sonic addition.” Two alternative solid-state topologies are cascaded to produce rich low-midrange harmonic content not found in other Avalon preamplifiers. This function gives the V55 a new scale of sound characters.

SONIC EXCELLENCE

The Avalon V55 DI-RE-MIC preamplifier is a professional preamplifier, DI and RE amp. Designed for maximum versatility, the V55 combines its sonic signature – “deep and controlled bass, musical mids, and enhanced vocal projection” – 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 LEDs, multiple outputs, including a transformer isolated instrument level re-amp. Designed to optimize absolute signal integrity and musical performance, the V55 is ideal for ribbon, dynamic and condenser microphones, bass guitars, acoustic instruments, electric guitars, keyboards, synthesizers and very low output passive pickups.

The state-of-the-art DI input stage offers very high impedance, “zero-load” effect on sensitive pickups and keyboards, while maintaining a huge input headroom of up to +36 dB from overload.

Technical specifications:

  • Audio Circuit Topology: 100% discrete, high voltage and Class A circuit.
  • Gain: Switchable 2 dB steps, -/+ 0.15 dB precision.
  • Input modes (4):
    – Line: Balanced, 6,000 Ω, XLR~TRS, Gain -3 dB to +36 dB, max. Input level 47 dB.
    – Instrument ~ DI: Unbalanced, 10,000,000 Ω, TRS, Gain +2 dB to +42 dB, max. Input level 36 dB.
    – Microphone HiZ: Balanced, 6,700 Ω, XLR, gain +20 dB to +60 dB, max. Input level 23 dB.
    – Microphone LoZ: Balanced, 1,760 Ω, XLR, gain +26 dB to +66 dB, max. Input level 19 dB.
    – PAD (passive input attenuator): Line -13 dB, Instrument -10 dB and Microphone -15 dB.
  • Phantom Power: 48V, regulated, 10mA, blue = current on, red = phantom power on.
  • Thru Output: Unbalanced, TRS with impedance buffering.
  • Max. Line output level: +30 dB, DC-coupled, balanced, 600 Ω, XLR~TRS.
  • Max isolated output level: +12 dB, transformer isolated, unbalanced.
  • Headphone output: 0.5W, 600 Ω, TRS.
  • Noise (20 kHz, unweighted): -100 dBu typical, minimum gain position.
  • Noise (ON, 22 Hz to 22 kHz): -128 dB at 40 dB gain (microphone output with low Z).
  • Distortion (THD, IMD): 0.05% at +10 dB output level.
  • Frequency response, -/+0.5 dB: 5 Hz to 50 kHz.
  • Frequency response, -3 dB: 2 Hz to 500 kHz (internally band-limited).
  • VU meter: Professional moving coil voltmeter, wide range -33 dB to 18 dB.
  • Signal LEDs: LED peak indicator, blue = 0 dB, red = 20 dB.
  • High Cut Filter: -3 dB at 4 kHz, design with minimal phase shift.
  • Phase reversal (polarity reversal): All outputs switched with relay, including isolated output.
  • Tone Shape: Ten “passive” voices to improve clarity, problem solving and musical enhancement.
  • AC power supply: Internal toroidal AC power supply, selectable between 115V and 230V, 50/60Hz, maximum power 35W per channel.
