Royer SF-2 Active Ribbon Microphones - Matched Pair
Additional Photos:
The SF-2's magnet/pole piece transducer structure gives a wide, uniform frequency response with no substantial peaks or dips, and the 1.8-micron ribbon element delivers superb transient response. Frequency response is excellent regardless of the angle of sound striking the ribbon and off-axis coloration is negligible.
Gain
Active Series 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 30 dB less sensitive than condenser mics, necessitating the use of high-quality, high-gain microphone preamplifiers when recording quieter sound sources like acoustic instruments, vocals, room ambiance, etc. The SF-2 contains a fully balanced, discrete head amplifier system which utilizes a specially wound toroidal transformer and ultra-low noise FET's to deliver a sensitivity of -38 dB. Even with extremely quiet sound sources, you'll have enough level to drive any recording medium.
The SF-2's electronics create no additional self-noise. All of the SF-2's higher output comes from its large, specially wound toroidal transformer which provides an additional 14 dB of 'free gain'. The phantom powered system operates at less than unity, adding no noise of its own.
Impedance Matching
The electronics in the SF-2 provide a perfect load to the ribbon element 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-2s can be used on extremely long cable runs with minimal signal loss.
Features

Protect your investment with the Long & McQuade Performance Warranty
A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.
Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.
How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
- Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
- Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
- No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
- Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
- Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
- Loaners Available: A loaner product may be given while the product is being repaired.
- Power Surge Protection: Your product is covered even if damaged from a power surge.
- Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
- Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.
Purchasing additional years of coverage
Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.
If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:
- NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
- USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
- GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
- BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
