Blue Bluebird SL Large-Diaphragm Cardioid Condenser Microphone
Key Features
  • Clear Tone for Vocals and Instruments
  • Cardioid Pattern Lessens Room Ambience
  • -20 dB Pad Eliminates Distortion
  • Low-Cut Filter Reduces Bass Buildup
Featuring a proprietary, hand-crafted capsule, the Blue Bluebird SL is a studio condenser microphone which builds upon its predecessor to provide a precise and clear sound as well as switchable filter and pad settings, ensuring great versatility for varied studio recording applications. It utilizes a large, gold-sputtered Mylar diaphragm, replete with a sculpted rear backplate to emphasize resonances at higher frequencies; this creates the clarity of treble, smoothness of midrange, and richness of lows, characteristic of Bluebird microphones, all while allowing sound sources to cut through a mix. Further elevating its professional nature is the shockmount, which absorbs vibrations to inhibit handling and stand noise.

Featuring a proprietary, hand-crafted capsule, the Blue Bluebird SL is a studio condenser microphone which builds upon its predecessor to provide a precise and clear sound as well as switchable filter and pad settings, ensuring great versatility for varied studio recording applications. It utilizes a large, gold-sputtered Mylar diaphragm, replete with a sculpted rear backplate to emphasize resonances at higher frequencies; this creates the clarity of treble, smoothness of midrange, and richness of lows, characteristic of Bluebird microphones, all while allowing sound sources to cut through a mix. Further elevating its professional nature is the shockmount, which absorbs vibrations to inhibit handling and stand noise.

Use the 100 Hz low-cut filter to attenuate bass buildup and increase intelligibility, which is especially important when the mic is close to the source. When miking drum kits or guitar amps, the -20 dB pad is perfect for keeping the sound clear and free of distortion. The mic's cardioid polar pattern rejects a good deal of sound behind the mic, allowing it to pick up less room ambience and background noise than many other polar responses. The Bluebird SL can be connected to any XLR mic input that is capable of sending 48V phantom power.

Behind the Mic
With the original Bluebird microphone, Blue set a new standard for modern recording mics. Bluebird SL advances that legacy with refined sonics and versatile switches to capture exceptionally clear and powerful sound that makes ears perk up and listen. Add in an updated design to inspire your best performances, and what you get is a best-selling Essential Series condenser mic.
Inside the Sound
Every component of Bluebird SL is specially designed to deliver crystal-clear tone. The hand-built capsule utilizes a fine, gold-sputtered Mylar diaphragm that delivers superior resonance at higher frequencies to help vocals cut through the mix. The sculpted rear backplate ensures balanced sound across the entire frequency spectrum. Plus, discreet Class-A circuitry maximizes the accuracy of your sound.
Make the Switch
Bluebird SL is a special mic for every kind of performance. The onboard switchable 100 Hz high-pass filter and -20 dB pad give you the flexibility to track a wide variety of sound sources with nuance and power. Use Bluebird SL to capture a singer's unique vocal character in stunning detail, achieve full-frequency guitar recordings, and more.
