Spark SL
Studio Condenser Microphone

Detailed, Transparent Sound
Behind the Mic
Based on the original Spark, the world's best-selling studio condenser microphone, Spark SL excels at delivering detailed and transparent sound to your recordings with a new level of versatility and sound quality. Featuring a new streamlined build, refined sonics and versatile switches, Spark SL will transform your creative space into a professional studio.
Inside the Sound
At the heart of Spark SL's sound is Blue's custom JFET design, which ensures the capsule's backplate is evenly charged, delivering consistent, transparent sound at all times. Spark SL also features discreet Class-A circuitry to maintain a pure signal. All you have to do is add music—Spark SL will make sure every detail comes through with precision and finesse.
Switch to Versatility
Spark SL features a new 100Hz high-pass filter and -20dB pad to bring professional versatility to your recording sessions. Tracking a strong, dynamic singer or blisteringly loud amp? No problem. Want to capture the nuanced frequencies of strings, drum overheads or horns? Done. Spark SL's incredible flexibility makes it easy to capture the detail of any voice or instrument.
