Burbank, CA… Royer Labs, a leading manufacturer of high quality ribbon microphones, is pleased to announce the SF-24V Vacuum Tube Stereo Ribbon Microphone is now shipping. Designed as a premium instrument for stereo and distance miking applications, the new SF-24V employs a dual vacuum tube design, and is the world’s first commercially produced vacuum tube stereo ribbon microphone. Like its sibling, the SF-24 Stereo Active Ribbon™ Microphone—but with greater headroom and faster transient response— the new SF-24V’s panoramic stereo pickup is particularly well suited to miking large ensembles such as an orchestra or the various sections within. It is also ideal as a single-point stereo overhead drum and percussion mic, and provides lush recordings of virtually all acoustic instruments.

The new SF-24V delivers high quality audio performance with outstanding stereo separation and imaging. The SF-24V is a single point stereo ribbon microphone, with the two coincident ribbon elements fixed at 45 degrees left and right of center for Blumlein X-Y and M-S recording, providing a familiarity of sonic performance associated with the original SF-24 microphone. The microphone’s ribbon elements are unaffected by varying mic preamplifier loads, heat or humidity, and are compatible with virtually all mic preamps. The SF-24V has extremely low residual noise, an absence of high frequency phase distortion, and exhibits equal sensitivity from either the front or back of the ribbon elements.

The new SF-24V’s active electronics utilize NOS (new old stock) U.S. military spec 5840W vacuum tubes that are conservatively operated and configured as cathode followers. The microphone’s high-voltage cathode follower circuit offers incredible headroom and dynamic range that is ideally suited for capturing a wide range of sound sources. Further, the microphone’s oversized, bi-filar wound toroid ribbon-matching transformers assure fast transient response.

The SF-24V’s tubes are conservatively rated to last 20 years or more. The tube heaters incorporate independent D.C. power supplies with a slow ramp-up feature. Jensen® 1:1 ratio output transformers provide an electrically isolated, fully-balanced output signal. The end result is a microphone that can drive virtually any preamplifier and long cable runs (from power supply to preamp) with ease. The SF-24V receives an extensive burn-in procedure to assure proper settling of the vacuum tubes.

Each of the SF-24V’s two ribbon transducers are housed in an ingot iron case that forms part of the magnetic return circuit. The magnet/polepiece structure of the transducers allows a wide, uniform frequency range with no substantial peaks or dips, and the two 1.8-micron pure aluminum ribbons produce superb transient response. Frequency response is excellent regardless of the angle of sound striking the ribbons, with negligible off-axis coloration.

The SF-24V's 7-conductor cable plugs directly into the power supply, which has two 3-pin male XLR output connectors labeled “Output 1� and “Output 2� for the microphone’s upper and lower capsules. The SF-24V’s compact dual channel power supply operates on 100, 120, 240-250 volts AC, 50-60 HZ. The SF-24V ships with a shock mount, a mic sock, and an elegant handcrafted presentation case carved from a solid block of Padauk wood. Royer Labs’ unconditional lifetime warranty is included.

“The new SF-24V represents an entirely new level of ribbon microphone performance,� says John Jennings, Royer’s VP of Sales and Marketing. “With even greater headroom and faster transient response than the original SF-24, its ability to accurately capture the most subtle performance nuances from a distance is positively breathtaking. The SF-24V is perfectly suited for orchestral and small ensemble recording where capturing the subtleties, nuance, and depth of performances is critical.�

The new SF-24V Vacuum Tube Stereo Ribbon Microphone’s suggested retail price is $5,895.00. The microphone is now available.
