Protect your investment with aPlatinum Coverage warranty plan:
There are no products for the condition you selected. Please make another selection.
This instrument or product has been carefully played/used and returned to us in
virtually new condition, however its packaging may not meet the standards set by
the factory. Also, it no longer carries the manufacturer's warranty. If you're looking
for a virtually new instrument in possibly less-than-perfect packaging, this is
a great value. We feel so strongly you'll like what you see, we're including our
60-Day Satisfaction Guarantee on instruments and 30 days on accessories, to this used product making it a no-risk purchase.
Very Good: This instrument or product has been carefully played/used and shows few,
minor signs of use. In most respects it looks and performs like new and may be considered
equivalent to display units found in retail stores. Its packaging may not meet the
standards set by the factory and it no longer carries the manufacturer's warranty.
Condition 2 products are a terrific value and you can buy with confidence knowing
our 60-Day Satisfaction Guarantee on instruments and 30 days on accessories applies to this used product.
This instrument or product is in good working condition but has one or more cosmetic
flaws beyond those of a Condition 2 product. These flaws are typical of an instrument
or product that's seen normal wear and tear, including incidental scratches, chips,
dings, dents or other imperfections. It performs just as well as a Condition 1 or
Condition 2 instrument/product. Its packaging may not meet the standards set by
the factory and it no longer carries the manufacturer's warranty. Condition 3 is
a great choice if you're looking for performance and value and not as concerned
with cosmetics. You can buy with confidence knowing our 60-Day Satisfaction Guarantee on instruments and 30 days on accessories
applies to this used product.
This instrument or product is not in working condition and needs repair, but can
be brought back to full functionality with replacement of parts or some skilled
repair work. If you are a do-it-yourselfer or know a skilled repair person this
is a terrific value. Condition 4 products are sold AS-IS: they do not come with
a manufacturer's warranty and are not returnable.
This instrument or product has been damaged beyond what we judge is reasonably repairable.
It's best used for spare parts or to practice repairs on, and at this price Condition
5 products are sold AS-IS: they do not come with a manufacturer's warranty and are
Accidental damage, normal wear and power surges are no longer an issue with these comprehensive and affordable plans. We even pay to ship your gear for repairs. More details.
Covers much more than the original manufacturer's warranty:
Limit of Liability: The least of the cost of (1) authorized repairs, (2) replacement with a product of similar features, (3) reimbursement for authorized repairs or replacement or (4) the price that you paid for the product.

Royer SF-24 Active Stereo Ribbon MicThe Royer SF-24 stereo ribbon microphone is a phantom powered version of Royer's popular SF-12 (#581146) stereo ribbon microphone. It combines the SF-12's high quality audio performance, outstanding stereo separation and imaging with Royer exclusive active electronics system for ribbon microphones. The SF-24's output of -38dB is a full 14dB more sensitive than Royer's non-powered SF-12, putting its sensitivity on par with that of phantom powered condenser microphones. The unique electronics and custom designed FET's used in the SF-24 mic allow for ultra-quiet operation, with self-noise of lower than 18 dB.The SF-24 is actually two matched ribbon microphones placed one above the other in a coincident pair, each aimed 45 degrees from center in the classic Blumlein configuration. The magnet/pole piece structure of each ribbon transducer delivers a wide, uniform frequency response with no substantial peaks or dips, and the 1.8-micron ribbons produce superb transient response. Frequency response is excellent regardless of the angle of sound striking the ribbons and off-axis coloration is negligible.The Royer SF-24's extension cable comes with a Y adapter that splits into separate 3-pin male XLR connectors labeled "Upper" and "Lower" for the upper and lower capsules of the microphone (when held vertically).GainRoyer active ribbon mics are as sensitive as phantom powered condenser microphones, allowing you to use virtually any mic preamplifier or board pre. Conventional ribbon microphones are 15 to 30dB less sensitive than condenser mics, necessitating the use of high-quality, high-gain microphone preamplifiers when recording softer sound sources like acoustic instruments, vocals and room ambiance. The SF-24 contains two fully balanced, discrete head amplifier systems utilizing specially wound toroidal transformers and ultra-low noise FET's, each delivering a sensitivity of —38dB. This lets you mate an SF-24 microphone to any preamplifier with average gain characteristics. Even with quiet sound sources, you'll have enough level to drive any recording medium.It is important to note that the SF-24's higher sensitivity does not create additional self-noise. All of the SF-24's increased level comes from its large, specially wound toroidal transformers - that wonderful thing called "free gain." The level at the each of the transformers is actually hotter than what comes out of the microphone. The phantom powered system operates at less than unity, adding no noise of its own. This system took years to develop and is in patent pending status.Impedance MatchingThe electronics in the Royer SF-24 provide a perfect load to the ribbon elements at all times, allowing the microphone to deliver 100% of its full sonic potential regardless of the input characteristics of the following mic pre. Due to its low-impedance output, SF-24's can also be used on extremely long cable runs with minimal signal loss.A good impedance match is critical to ribbon microphones. Impedance mis-matching loads a ribbon improperly, resulting in loss of low end, diminished body, lowered sensitivity and an overall compromised performance. With Royer Active Series ribbon mics, the ribbon element sees a perfect impedance at all times, regardless of the preamp you use, so its performance will never be compromised by the effects of improper loading. In addition, the ribbon element cannot be damaged by phantom power, electrical glitches or mis-wired cables.Recording with the SF-24Like the SF-12, the SF-24 ribbon mic is uncanny for creating 'you-are-there' stereo recordings that capture not only the instrument(s) being recorded, but, depending on how the microphone is positioned, varying degrees of the acoustical space. In addition, the increased sensitivity and impedance matching circuitry allows for more consistent results in a variety of recording situations and with a wider selection of mic preamps.For mono recording, phase compatibility between the two sides of the SF-24 is excellent. This allows you to combine the two channels perfectly in mono without creating undesirable phase artifacts. This is particularly useful when capturing a wide sound field in mono; for instance, a singer who tends to move off the 'sweet spot' of a mono microphone. Either side of the SF-24 can also be used individually as a mono microphone.The Royer SF-24 Ribbon Microphone excels on classical piano, drum overheads, ensemble and orchestral recordings, a wide variety of percussion instruments, virtually all acoustic instruments, small vocal ensembles, large choirs, etc.
