Blue Spark Studio Condenser Microphone
We designed the Blue Spark to bring professional studio performance to your home recording space. At the heart of this large-diaphragm condenser microphone sits our handcrafted 20mm custom capsule, tuned to capture the warmth and detail that made our microphones legendary in world-class studios.
Whether you're recording vocals, acoustic guitar, or hosting your podcast, the Spark delivers clarity and presence that elevates every take. Our proprietary Focus Control switch lets you shape the mic's response to match your room acoustics and source material—cutting through problem frequencies or opening up the high end when you need extra air and detail.
The Spark arrives ready to record with a custom shockmount that isolates the capsule from vibration and handling noise, plus a rugged wooden storage box that protects your investment between sessions. We built this microphone to become the centerpiece of your creative workflow for years to come.
What makes the Spark studio-ready
Capsule Design & Acoustic Performance
We hand-tune every 20mm capsule in the Spark to deliver the balanced frequency response and smooth transient response that professional engineers expect from a studio condenser. The large-diaphragm design captures low-frequency warmth and body while maintaining exceptional detail in the vocal presence range.
Our cardioid polar pattern focuses on sound sources directly in front of the microphone while naturally rejecting off-axis noise—essential when you’re recording in untreated home studio spaces. The capsule’s pressure-gradient design provides consistent tone even when you move slightly during a take, giving you forgiving performance that still sounds polished.
Focus Control Technology
Two Voicings in One Microphone
The Focus Control switch on the Spark’s body gives you two distinct sonic characters without reaching for EQ plugins. In the normal position, you get our signature Blue voicing—present midrange with extended highs that help vocals cut through dense mixes.
Flip the switch to engage the -20 dB pad and high-pass filter simultaneously. This setting tames harsh room reflections, controls proximity effect on close-miked sources, and protects the capsule when recording loud instruments like guitar cabinets or brass. We designed this feature after years of watching engineers reach for the same corrective moves in post-production—now you can make those decisions at the source.
What's Included with Your Spark
Every Blue Spark ships with our custom shockmount designed specifically for this microphone’s weight and dimensions. The elastic suspension isolates the capsule from vibrations transmitted through your mic stand—footsteps on the floor, desk bumps, even building rumble disappear from your recordings.
We include a beautiful wooden storage box that protects the Spark between sessions and looks elegant on your studio shelf. The fitted interior keeps the microphone secure during transport to sessions or when you need to pack your studio temporarily.

Common Questions About the Blue Spark Microphone
Yes, the Spark connects to any audio interface with an XLR input and +48V phantom power. This is the industry-standard voltage that all modern interfaces provide through a dedicated button or switch.
Simply connect the Spark to your interface with a standard XLR cable, activate phantom power, and the blue LED on the microphone will illuminate to confirm it's receiving power and ready to record. The Spark does not connect via USB—it requires an XLR interface.
The Spark features our warm, present voicing that's optimized for vocals and general studio use, with a cardioid-only pickup pattern. The Spark SL offers a more transparent, neutral response with switchable cardioid and figure-8 patterns for advanced stereo recording techniques.
Both microphones use premium hand-tuned capsules, but we designed the original Spark to be the more versatile choice for singer-songwriters, podcasters, and home studio owners who want professional results with minimal tweaking.
Absolutely—engage the Focus Control switch to activate the -20 dB pad, and the Spark can handle maximum sound pressure levels up to 138 dB without distortion. This makes it suitable for close-miking guitar cabinets, brass instruments, and even drum overheads.
The pad reduces the microphone's output by 20 decibels before it reaches your preamp, preventing overload on extremely loud sources. The high-pass filter that engages simultaneously helps control low-frequency buildup in close-miking situations.
We recommend starting 6-8 inches away for most vocal applications. This distance provides a balanced tone with natural proximity effect warmth while giving you room to move slightly without drastic tonal changes.
If you prefer a more intimate, bass-heavy sound, move closer to 4-6 inches and consider engaging the Focus Control to manage proximity effect. For brighter, more open vocals with less proximity warmth, increase distance to 10-12 inches. Always use a pop filter when working closer than 6 inches to eliminate plosive sounds.
The Spark excels for podcast and broadcast applications thanks to its vocal-forward frequency response and excellent off-axis rejection. The cardioid pattern naturally reduces room noise and rejects sound from behind the microphone, which is essential for untreated recording spaces.
Many podcasters and streamers choose the Spark over USB microphones because it provides upgrade flexibility—as your content grows, you can enhance your signal chain with better preamps and processors while keeping the same microphone. The Focus Control helps you achieve broadcast-ready sound even in challenging acoustic environments.
The Spark is built for years of reliable performance with minimal maintenance. Store it in the included wooden case when not in use to protect the capsule from dust and physical damage. Avoid exposing the microphone to moisture, extreme temperatures, or tobacco smoke, which can degrade the capsule over time.
Never blow into the microphone or expose it to wind without a windscreen—sudden pressure changes can damage the sensitive diaphragm. If the microphone becomes dusty, gently brush the grille with a soft, dry brush. Never apply liquids or attempt to clean inside the grille, as this can permanently damage the 20mm capsule.
The included shockmount fits any standard microphone stand with 5/8-inch threading (the universal studio standard). We recommend a sturdy desktop boom stand or floor stand that won't sag under the Spark's weight—the microphone and shockmount together weigh approximately 1.2 pounds.
For desktop recording, consider our Compass broadcast boom arm, which provides smooth positioning and hidden cable management. Avoid lightweight stands that may tip over or allow the microphone to droop during long recording sessions.
