Key Features
- Vacuum Tube Electronics:
- The SF-24V integrates twin head amplifiers featuring low-noise, triode-connected military-grade 5840 vacuum tubes. This design provides increased midrange reach, unmatched clarity, and exceptional detail.
- Coincident Pair in Blumlein Configuration:
- Similar to the SF-12, the SF-24V consists of two matched ribbon microphones arranged in a Blumlein configuration. Each ribbon is positioned 45 degrees from center, offering outstanding stereo imaging.
- 1.8-Micron Ribbons:
- The SF-24V incorporates two 1.8-micron ribbons, each weighing approximately 1/3 milligram. These ribbons contribute to superb transient response and a wide, uniform frequency response.
- Magnet/Pole Piece Structures:
- The ribbon transducers utilize magnet/pole piece structures, ensuring a consistent frequency response without substantial peaks or dips.
- Dedicated Power Supply:
- The SF-24V includes a dedicated power supply that provides ample current to the vacuum tube electronics, enhancing the microphone's performance.
- Fully Balanced Outputs:
- The microphone's fully balanced outputs, electrically isolated with special-purpose Jensen output transformers, virtually eliminate induced noise.
- Large Toroidal Transformers:
- Specially wound toroidal transformers provide increased sensitivity, allowing the SF-24V to deliver a -38 dB output suitable for use with any professional preamplifier.
- Low Self-Noise:
- With self-noise lower than 18 dB, the SF-24V ensures ultra-quiet operation, making it suitable for demanding classical and acoustic recording applications.
- Vacuum tube circuitry provides high output and impedance matching
- True stereophonic (Blumlein and M-S) recording from one coincident microphone
- High SPL capabilities
- No distortion up to maximum SPL rating
- Extremely low residual noise
- Ribbon elements are not affected by heat or humidity
- Absence of high frequency phase distortion
- Equal sensitivity from front or back of elements
- Consistent frequency response regardless of distance
- High efficiency, matching toroidal transformers
- Very low magnetic leakage
Recording Applications
- Full Orchestra, Choir, and Ensembles:
- The SF-24V excels in capturing the nuances of large musical ensembles, offering exceptional stereo imaging and detail.
- Classical Piano:
- Ideal for recording classical piano with richness and natural sound reproduction.
- Drum Overheads:
- Well-suited for drum overhead applications, providing realistic stereo imaging and powerful drum tracks.
- Acoustic Instruments:
- Versatile for recording a wide variety of acoustic instruments with clarity and fidelity.
- Vocal Groups:
- Suitable for capturing small vocal groups or choirs with a natural and immersive sound.
- Room Mic:
- Functions effectively as a room microphone, capturing the ambiance of the recording environment.
Recording in Mono
- Phase Compatibility:
- The SF-24V exhibits excellent phase compatibility between its two sides, allowing seamless combination of the two channels for mono recording without phase artifacts.
- Independent Mono Use:
- Each side of the SF-24V can be used independently as a mono microphone, providing flexibility in recording applications.
