discontinued Multi-Pattern Condenser Tube Microphone

Soundelux U99B

Description

The U99 features a hand-made European 1'' diameter dual backplate, dual membrane capsule. Each hand-tuned capsule uses 6 micron Mylar specially selected for consistent thickness and is sputtered with a unique blend of gold and aluminum for excellent transient response and long life. The backplate design is from the K67 family.

The electronics feature an EF86 tube run as a triode. Soundelux rigorously selects each EF86 for the best distortion, signal handling and noise specifications. The electronics package uses only 12 components, each of the finest quality and tightest tolerances.

For the utmost in reliability and sonic purity, the U99 has no
internal connectors (direct soldering only), switches or screws on the massive body of nickel, chrome and brass alloy.

The electronics have been configured in a zero-feedback arrangement for maximum transient response and absolute phase coherency. This is the most direct and true manner in which to translate sounds from the acoustic to the electronic medium.

The high headroom, low noise, and wide bandwidth required by today’s engineers are assured by the circuit design. The unique beefy regulated power supply can deliver up to four times the current required by the mic, to assure years of stable and reliable service.

The U99 is essentially a redesign and upgrade of Soundelux’ original multipattern tube mic, the U95, which was based on a tube that became too scarce (the 6072). The U99 also introduced a continuously variable polar pattern mechanism, as opposed to the stepped design of the U95.

The Soundelux U99B is also known as: U99.

The mic was released in 2000.
