Product Description

Discover a world of sonic possibilities with the 86B-2, an American-style stereo tube preamp meticulously designed for engineers and producers seeking exceptional versatility in their recordings. From luscious vocals to vibrant acoustics, punchy drums to richly saturated tube warmth, this preamplifier offers an expansive sonic palette that will elevate your music to new heights.

Drawing inspiration from the golden age of 1950s American-style tube circuitry, the 86B-2 leaves a colossal harmonic footprint on your audio, injecting life and character into every note. Say goodbye to sterile, lifeless signals and welcome the vibrant warmth and organic sound that only genuine tubes can provide.

Longing for more color options without the hassle of switching between preamps? Perhaps you're tight on rack space or just beginning your journey with outboard gear and crave the utmost versatility. Look no further, as the 86B-2 offers precisely the flexibility you seek. Record with mics, then utilize the 'Line' mode to send audio back through tubes and transformers, infusing your sound with captivating coloration.

Prepare for sonic excellence with the 86B-2's premium MuMetal shielded inputs and nickel & steel outputs. These exceptional transformers lay the foundation for pristine audio transmission, ensuring remarkable fidelity and clarity. With an EF86 input tube and a 12AY7 output tube, the 86B-2 amplifies your signal with up to 75 dB of maximum gain, providing ample headroom for any recording scenario.

Keep a close eye on your levels with the built-in output level LED indicator. The three-color LED (green, yellow, and red) offers instant visual feedback, allowing you to maintain optimal signal levels throughout your recording process.

Experience worry-free recording with dedicated XLR input connectors designed for seamless audio transmission without the risk of phantom power interference. Simply connect and record with confidence, knowing that your signal is protected.
