OmnidirectionalCardioidBidirectionalBlue Microphones Stage Two

Detachable-Capsule Tube Condenser Microphone

Blue’s Bottle Rocket Stage Two was formerly known as the Red Mic Type A. It is a tube condenser microphone with a bayonet mount that accepts a variety of detachable capsules.

The tube is an ECC88, a dual-triode tube. The output circuit is transformerless; three transistors are used for impedance conversion.

Blue’s B0-B8 capsules were formerly branded as Red’s R1-R8 but are believed to be identical. Violet Design’s VIN series of capsules, and Neumann bayonet-mount capsules are also compatible.

The mic’s self-noise level varies from 9dbA to 14dBA, depending on the capsule used.

For more information and reviews, see the Red Type A profile.

Electronic Musician, 2009
This kit has a decidedly upscale presentation, with a lavish ATA flight case sporting heavy-duty metal hardware. When opened, the case practically glows with regal-looking blue velvet. Cutouts are provided for the mic body, three capsules and the tube electronics’ power supply. A blue-velvet door lifts to reveal a five-conductor mic cable, shockmount and power cable.

With its glossy finish, the Stage Two is particularly prone to slipping down in the mount until it comes to rest on the raised logo or one of the end caps. Although there’s no danger of the mic body falling out or getting damaged, this is a design flaw that goes against Blue’s reputation for aesthetics and precision.

Neither the Stage One nor the Stage Two compromise on the sound quality and excellent specs for which Blue is known.

The Blue Microphones Stage Two is also known as: Stage-2.

The mic was released in 2008.
