Description
Overview
The Royer Labs SF-24 is a professional stereo active ribbon microphone designed to deliver exceptional audio performance, precise stereo imaging, and outstanding separation. Built as a phantom-powered evolution of the SF-12, the SF-24 integrates an exclusive active electronics system that significantly boosts sensitivity and output, making it a powerful tool for capturing complex acoustic environments with the natural warmth and transparency characteristic of high-end ribbon transducers.
Key Details
- Active Electronics: Features phantom-powered circuitry that provides an output of -38 dB, offering 14 dB more sensitivity than passive counterparts and matching the output levels of condenser microphones.
- Blumlein Configuration: Consists of two matched ribbon microphones placed in a coincident pair, each angled 45 degrees from center to capture a true stereophonic image.
- Ultra-Quiet Operation: Utilizes custom-designed FETs to ensure extremely low self-noise (below 18 dB), allowing for clean recordings of quiet sources.
- Precision Transducers: Equipped with 1.8-micron ribbons and a specialized magnet/pole piece structure for a wide, uniform frequency response and superb transient response.
- High-Efficiency Components: Integrated toroidal transformers ensure high efficiency and very low magnetic leakage.
- Environmental Stability: Ribbon elements are engineered to remain unaffected by changes in heat or humidity.
Use Cases
- Stereo Field Recording: Ideal for capturing the natural ambiance of concert halls, churches, or outdoor environments using the Blumlein technique.
- Ensemble Recording: Perfect for piano, harp, or small acoustic ensembles where a cohesive and accurate stereo image is required from a single microphone position.
- Overheads and Room Mics: Excellent for drum overheads or room microphones, providing high SPL handling without distortion.
- M-S Recording: Capable of Mid-Side (M-S) recording configurations for flexible control over stereo width during the mixing process.
Installation
The SF-24 is designed for straightforward integration into professional signal chains. It requires +48V phantom power to operate its active circuitry. The microphone includes an extension cable equipped with a Y-adapter, which splits the signal into two separate 3-pin male XLR connectors. These are clearly labeled as Upper and Lower, corresponding to the capsules when the microphone is held vertically, allowing for direct connection into two channels of a preamp or audio interface.
Compatibility
- Power Requirement: Requires a preamp or audio interface capable of providing standard +48V phantom power.
- Connectivity: Standard 3-pin XLR outputs (via included Y-adapter).
- Mounting: Compatible with standard microphone stands and shock mounts.
