A matched stereo condenser pair with vintage vibe.

With the SP-1 standard pencil microphone pair and included Hemisphere mic modeling software (free upon registration), you can record acoustic instruments, drums and percussion, and live performances in stereo, with pristine fidelity for instant album-quality sound.

The Perfect Pair for Stereo Recording

As a matched stereo pair, the SP-1 adds clarity, width and dimension to your recordings. Whether it’s tight X/Y patterns or spaced pairs, combine them how you want and hear the detail in your instrument like never before.

Get the Sounds of Classic Small-Diaphragm Condensers With Hemisphere

Using the same award-winning tech as Universal Audio's Sphere modeling microphones, the free Hemisphere mic modeling plug-in gives you the authentic sound of iconic mics from AKG and Neumann—in real time with Apollo or natively in your DAW.* You can also shape the sound of your recordings using filter, proximity effect, and axis controls—even after tracking.

Capture Your Best Sounds Anywhere

The SP-1’s classic cardioid design, high SPL tolerance and smooth, clear top end deliver consistently clean capture of acoustic guitars, drum overheads, percussion, horns, and more—at any volume, in any environment.

More Than Your Average Pencil Mics

Universal Audio engineered the SP-1 pair to be your workhorse, everyday choice for stereo recording. With a retro finish and road-worthy build, these stylish condensers are a serious studio upgrade, with vintage elegance for days.
