Blue's newest professional mic, Spark, is a cardioid, solid-state condenser microphone designed to help you achieve professional quality recordings in any creative environment. Spark features a custom-designed condenser capsule with Class-A discrete electronics resulting in superbly detailed and uncolored output, making it the ideal microphone for recording vocals, drums, guitars, pianos, brass, woodwinds, and just about anything else you can light a fire under.
A new feature found only on the Spark microphone is the unique Focus Control, providing two different usage modes at the push of a button: the Normal mode (out position) providing increased low frequency sensitivity for recordings with great impact and definition, along with the Focus mode, (in position) for even greater clarity and detail.
The Spark microphone ships with a custom-designed pop-filter and shockmount as well as a convenient and stylish wood case for transport. With Spark, you've got everything you need to make professional recordings, all in one package.Technology
The Focus Control functions differently than a standard high-pass or low-pass filter– it changes the input driver of the capsule rather than the signal output of the microphone circuit. This avoids coloring or degrading the signal quality coming out of the Spark microphone like low or high pass filters can. Specifically, the Focus Control alters the voltage loading of the capsule, which alters the capsule's dynamic frequency response, changing the capsule's behavior in a way that's more nuanced than a standard filter acting on a microphone's output. The result is a change to Spark's frequency response curve as well as the dynamic properties of the capsule (response to transients), providing two different mic characteristics.
