Royer Ribbon Microphones: The Lineup and What Each Mic Is For (2026)
Royer Labs ribbon microphones are new at Blackout Audio. The range starts at $849 CAD for the passive R-10, and Royer's flagship R-121 is $2,059 CAD. These are mics for engineers and players who record electric guitar cabinets, brass, drum overheads and acoustic instruments and want the warm, natural sound of a ribbon on those sources.
Every Royer on our store uses a figure-8 ribbon element. The models differ in what sits behind the ribbon. The R-10 and R-121 are passive, with nothing inside that needs power. The R-122 MKII, SF-2 and SF-24 have phantom-powered electronics, and the R-122V and SF-24V run on a vacuum tube with their own power supply. That choice decides how much preamp gain you need, so this guide covers it first.
The Royer Microphones We Carry
Seven microphones make up the range on our store: four mono R-Series mics, the mono SF-2, and two stereo SF models.
Passive or Active: Which Ribbon Suits Your Setup
A passive ribbon sends its signal through a transformer and straight down the mic cable. It needs no phantom power, and the R-121 has no electronics to distort below its maximum SPL of more than 160 dB. The trade-off is output. The R-121's sensitivity is -47 dBV and the R-10's is -54 dBV, so a quiet source asks your preamp for a lot of clean gain.
An active ribbon adds a small amplifier inside the body, powered by 48 V phantom. The R-122 MKII puts out -36 dBV, and the SF-2 and SF-24 put out -38 dB, on par with a phantom-powered condenser. Almost any preamp or interface has enough gain for that. The electronics also give the ribbon the same load whatever preamp follows, so the mic keeps its low end on any input, and they drive long cable runs with little loss.
The tube models, the R-122V and SF-24V, do the same job with a vacuum tube. Each comes with a dedicated power supply that feeds the tube, and the supply connects to your preamp.
Pick a passive ribbon if most of what you record is loud. Guitar amps, brass and drum rooms give a passive mic plenty of signal. Pick an active or tube ribbon if you record quiet sources such as acoustic guitar, strings or voice-over, or if your interface gets noisy near the top of its gain range. A third route is a passive mic plus Royer's dBooster2, which adds 12 dB or 20 dB of clean gain per channel before your preamp.
R-10: The Entry Point, $849 CAD
The R-10 is the least expensive Royer microphone on our store, a passive ribbon hand-built in Burbank, California for the studio and the stage. It uses the same aluminum ribbon as the R-121 and handles more than 160 dB SPL, so you can put it close to a loud guitar cabinet or a trumpet. A three-layer windscreen and an internally shock-mounted ribbon soften plosives and protect the element when you mic up close.
Royer's offset-ribbon design gives the R-10 two voices. The front (logo) side takes loud sources. The back side sounds brighter and suits quieter ones such as acoustic guitar, ukulele and close vocals, with the polarity reversed. Royer lists electric and acoustic guitar, brass and horn sections, drum overheads and rooms, percussion, strings, piano and vocals.
At -54 dBV the R-10 has the lowest output in the range, and Royer bundles it with a booster for quiet sources. The R-10 with dBooster is $1,049 CAD and adds 12 dB or 20 dB of clean gain between the mic and your preamp. A matched pair of R-10s for stereo is $1,749 CAD, and the R-10 matched pair with dBooster2 is $2,099 CAD.
R-121: The Guitar Cabinet Ribbon, $2,059 CAD
The R-121 is Royer's flagship passive ribbon. It came out in the 1990s and is still a first choice for electric guitar cabinets in studios and on live stages. With no active electronics inside, a wide-open amp or a trumpet played full out will not push it into distortion below its maximum SPL.
Its output of -47 dBV is higher than the R-10's, and it has the same offset ribbon with a brighter back side for acoustic instruments and vocals. Flip the polarity at the preamp or in your DAW when you record on the back. Royer also lists brass and horn sections, drum rooms, kick drum, woodwinds, acoustic piano, strings and choirs.
The R-121 with Royer's RSM-SS1 Sling-Shock mount is $2,259 CAD. The Sling-Shock hangs the mic on nylon cord and damped steel springs, so it adds none of the self-resonance a conventional shock mount can produce on a close-miked cabinet. The R-121 matched pair is $4,239 CAD, and the pair with two Sling-Shocks is $4,649 CAD.
Engineers have paired the R-121 with a 57-style dynamic on guitar cabinets for years. The AxeMount, $79.99 CAD, holds both mics on one stand, with an arrow that marks the in-phase position for the dynamic. Royer developed it with SLR of Windsor, Ontario, and SLR builds it in Canada. As a starting point, Royer aims the dynamic where the speaker's dome meets the cone, sets the R-121 more over the dome, and blends the two to taste.
R-122 MKII: The Active R-121, $2,599 CAD
The R-122 MKII puts a phantom-powered head amplifier behind the same offset-ribbon transducer as the R-121. Its -36 dBV output works with almost any preamp, so quiet sources such as acoustic guitar, strings and voice-over get enough level.
Two recessed switches on the back let one mic cover loud and quiet work. A -15 dB pad sits ahead of the electronics, so a wide-open guitar amp cannot drive them into distortion. A bass cut at 100 Hz reduces the low-end buildup you get on close vocals, acoustic instruments and close-miked guitars.
Royer says the MKII's faster transient response gives more open highs and a tighter low end than the R-121, and suggests it for drum overheads, piano, strings, acoustic instruments and vocals. With a Sling-Shock mount it is $2,879 CAD. The R-122 MKII matched pair with two Sling-Shocks is $5,899 CAD.
R-122V: The Tube Ribbon, $4,519 CAD
The R-122V is the top model in Royer's R-Series. It runs the same offset ribbon through a low-noise 5840 vacuum tube and a Jensen output transformer, which gives it high output, plenty of headroom and a rich, detailed midrange. Royer designed the circuit to avoid the usual tube coloration.
Its power supply, a 25 ft 7-pin cable and a shock mount come in the box. Royer recommends letting the mic warm up for at least 15 minutes before you record. It suits orchestral and string recording, piano and harp, vocals and voice-over, and Royer also lists electric guitar, brass and drum overheads.
SF-2: Active Ribbon for Classical and Acoustic Work, $2,749 CAD
The SF-2 is a phantom-powered mono ribbon designed for classical recording and acoustic instruments: choir, strings, woodwinds, piano, harp and acoustic guitar. Its 1.8-micron ribbon is thinner than the R-Series element and gives fast transient response. At -38 dB its output is on par with a phantom-powered condenser.
Keep the SF-2 for acoustic sources. Its maximum SPL is 130 dB at 70 Hz, below the R-Series mics, so use the R-121 or R-10 on a cranked guitar amp. The matte black finish cuts reflected light on stage and on camera, and prototype SF-2s spent years in major studios and on scoring stages before release.
The SF-2 matched pair is $5,599 CAD, for stereo work on choirs, orchestras, string sections, piano and drum overheads.
SF-24 and SF-24V: Stereo From One Mic
Both stereo models hold two matched ribbons, one above the other, each aimed 45 degrees from center as a Blumlein pair. One mic on one stand records true stereo in Blumlein or mid-side. The two sides stay in phase when summed to mono, and either side works on its own as a mono figure-8.
The SF-24 is $5,699 CAD and active. It needs 48 V phantom on both channels and comes with a 25 ft 5-pin extension cable and a splitter cable with two XLR leads marked Upper and Lower. Royer suggests it for classical piano, drum overheads, orchestras and ensembles, percussion, acoustic instruments and choirs.
At $7,199 CAD, the SF-24V uses the same tube electronics as the R-122V, one 5840 tube per channel. Royer says the tubes add midrange reach, clarity, detail and air. Its power supply delivers the two channels on standard XLR outputs, and Royer recommends it for full orchestra, choirs and ensembles, classical piano, drum overheads and acoustic instruments.
A matched pair of mono mics covers the same Blumlein and mid-side setups and also lets you space the two mics apart. Royer's manuals suggest a spaced pair over the bass and treble strings of a piano, or a pair 4 to 6 feet above a drum kit. The FlexBar, $369 CAD, holds two mics on one stand with independent arms and an engraved centimeter scale, so you can write down a setup that works and rebuild it exactly. It also mics the top and bottom of a snare from a single stand.
dBooster2: More Gain for Passive Ribbons, $479 CAD
The dBooster2 sits between a passive ribbon and your preamp and adds 12 dB or 20 dB of clean gain on each of its two channels. It runs on 48 V phantom from your preamp or interface and blocks that phantom from reaching the mic.
Each channel also works as a DI for guitar or bass. Because the channels are independent, one box handles a stereo ribbon pair, two DIs, or one mic and one DI at the same time. Royer pairs it with the R-121 and R-10, and it also brings up dynamic mics such as the Shure SM7B and Electro-Voice RE20. Phantom-powered condensers will not work through it.

Which Royer for Which Job
- Guitar cabinets. Start with the R-121. The R-10 does the same job for less, and the AxeMount adds a 57-style dynamic on the same stand.
- Brass and horns. The R-121 and R-10 both take more than 160 dB SPL, so you can mic a trumpet up close.
- Drum overheads. The SF-24 gives you stereo from one mic on one stand. A matched pair of R-122 MKIIs or R-10s lets you space the mics.
- Vocals and voice-over. Go active with the R-122 MKII, or the R-122V if you want tube electronics.
- Choir, strings and classical piano. The SF-2 is built for this work in mono, and the SF-24 and SF-24V cover it in stereo.
Looking After a Ribbon Mic
Wind is one of the common ways a ribbon gets damaged. Royer warns against using a ribbon outdoors without a wind filter and against placing one near vents or doors. Royer says its mics travel well when they stay in their cases between gigs. Heat and humidity do not affect the ribbon element.
Royer says phantom power will not damage its ribbons under normal working conditions. The risk comes from miswired cables and from cross-patching mics at a patch bay with 48 V on, which can send a voltage spike that stretches the ribbon. Turn phantom off or unplug the mic before you repatch.

Frequently Asked Questions
Do Royer ribbon microphones need phantom power?
The passive R-10 and R-121 need no phantom power. The active R-122 MKII, SF-2 and SF-24 need 48 V phantom to run. The tube R-122V and SF-24V run on their own included power supplies.
Will phantom power damage a passive Royer like the R-121?
Royer says phantom power will not damage its ribbons under normal working conditions. Miswired cables and cross-patching at a patch bay with 48 V on can send a spike that stretches the ribbon, so turn phantom off before you repatch.
Which Royer is best for electric guitar amps?
The R-121. It is still a first choice for guitar cabinets in studios and on stage, and it takes more than 160 dB SPL. The R-10 uses the same ribbon at $849 CAD.
Can I use a passive ribbon with a basic audio interface?
On loud sources such as guitar amps and brass, a passive ribbon gives plenty of signal. On quiet sources such as acoustic guitar or vocals, an interface can run short of clean gain. The dBooster2 adds 12 dB or 20 dB before the preamp, and the R-10 is also sold with a dBooster for quiet sources.
What is the difference between the R-121 and the R-122 MKII?
Both use the same offset-ribbon transducer. The R-122 MKII adds phantom-powered electronics for -36 dBV output, a -15 dB pad and a 100 Hz bass cut. Royer says it has more open highs and a tighter low end, and suggests it for drum overheads, piano, strings, acoustic instruments and vocals.
