Bottle
Pour it on.
Absolute Sound Perfection Congratulations on your purchase of the Blue Bottle, a classic modern vacuum tube microphone made the old-fashioned way, without compromise. In every industry — cameras, automobiles, audio, and more — there are a handful of small companies reputed for a rare blend of scientific precision and artistic passion. You know who these artisans are; their trademarks are synonymous with the ultimate in handcrafted perfection.
The Bottle One of the questions most commonly asked of Blue Bottle microphone owners is, “What’s in that thing?” The Bottle is unquestionably an impressive sight, with its imposing size and nostalgic resemblance to the earliest European tube microphones. Like the mics of yesteryear, the Bottle canister is not just for looks, but also holds a small fortune in precision electronics.
Capsule Exchange When you’re used to dealing with an assortment of tube microphones (each with its own mounting system and power supply, not to mention additional voltage transformers, fragile parts, and other quirks), you’ll really appreciate the simplicity and ease of the Bottle capsule system. Switching capsules is a painless 30-second operation which eliminates downtime and warm-up time, and will never interrupt the flow of a session.
Technical The Bottle vacuum tube amplifier consists of a classic common cathode circuit using a current source for the plate load, rather than the more commonly used simple resistor. The amplified signal is taken from the plate and fed through a high-quality polypropylene capacitor, bypassed by a smaller value polystyrene capacitor (Russian MIL spec), and output to our Blue custom hand-built transformer.
forcefully attracts electrons from the not yet heated cathode, a process known as “cathode stripping”. In practicality, this means that each time the power supply is switched on, the microphone tube changes its electrical properties. To put it simply, the tube begins to wear and gets noisier. To avoid this problem the Power Stream SOFT START feature delivers the tube’s heater voltage first.
