Tribute to the King of Microphones

The U47 is widely regarded as one of the most iconic microphones ever made, celebrated for its detailed and balanced tone. The Heiserman H47Tube is a meticulously crafted tribute to this legendary mic, capturing the essence of the original while offering modern performance.

Through extensive side-by-side comparisons with vintage U47 models, Heiserman has fine-tuned the H47Tube’s components to perfectly replicate the original’s tone. The result is so close to the vintage mic that Grammy-winning engineers have noted its remarkable accuracy.

Authentic Design, Premium Components

Heiserman’s H47Tube doesn’t just sound like the original—it looks and feels the part as well. From the integrated polar pattern switch to the headbasket’s exact mesh dimensions, every detail is designed to evoke the classic U47 aesthetic. Crafted by hand, this premium microphone is built for engineers and producers seeking the finest in pro audio equipment.

Two Capsule Options for Tailored Sound

The H47Tube is available with a choice of two capsules: the HK47 and the HM7. The HK47 offers a balanced tone suited for both vintage and modern productions, making it the ideal choice for most users. For those seeking a more vintage sound with a slightly rolled-off high-frequency response, the HM7 capsule—an accurate reproduction of the original M7—is available.

True-to-Original Circuit Design

The Heiserman H47Tube features a circuit that remains true to the original, utilizing 100% through-hole components. Each element has been meticulously tested to ensure it delivers the renowned U47 sound. The microphone includes:

• Custom-made BV08 transformer
• NOS EF8XX Series Tube
• Sommer tube cable with custom connector
• NOS Mial Polystyrene Capacitor
• NOS Soviet Paper-in-Oil Capacitors
• Premium Ohmite Thick Film and KOA Speer Resistors

Each of these components contributes to the exceptional performance and tonal clarity of the H47Tube.

Durability Meets Elegance

While the H47Tube draws inspiration from vintage microphone designs, Heiserman has updated the packaging to meet modern standards. Instead of a traditional wooden box, the H47Tube ships in a durable Pelican case with custom-molded foam. The laser-cut, cross-linked polyethylene foam provides superior shockproof and waterproof protection, ensuring the microphone is safe during transport and storage.
