Lewitt PURE TUBE Studio Set

Lewitt PURE TUBE Studio Set

The Lewitt PURE TUBE is a premium studio tube microphone engineered to deliver modern, warm and exceptionally clean vocal recordings. Its 1-inch true condenser capsule with cardioid polar pattern is paired with a revolutionary tube circuit fully free from semiconductors and capacitors, providing maximum clarity and a smooth, musical high end.

Revolutionary tube circuit

PURE TUBE features a 3 μm gold-sputtered Mylar membrane housed in an externally polarized 1" capsule. A hand-selected 12AU7/ECC82 tube drives a puristic signal path that adds gentle warmth, subtle harmonic character and a naturally rounded top end. The circuit is engineered entirely by Lewitt’s innovation lab.

Optimized for vocals

The microphone is designed to help vocalists perform at their best. It handles intimate recordings, layered vocal stacks and heavy compression without unwanted noise — offering a full, present and inspiring vocal sound.

Ultra-low noise floor

Thanks to its puristic circuit design, PURE TUBE achieves a remarkably low self-noise of only 7 dB(A), making it ideal for critical vocal work, whisper-quiet passages, voice-over, and detailed acoustic recordings.

Studio-ready construction

The Studio Set includes a magnetic pop filter, integrated shock mount and a compact worldwide power supply (110–230 V). The microphone body is made of durable zinc die-cast for long-term reliability.
