In order to familiarize yourself with the Bluebird SL’s
specialized and unique features, please read this
manual thoroughly and try the suggested recording
tips. With proper care and use, the Bluebird SL will
reward you with many years of recording enjoyment.
Unlike other Bluebirds you may know of, this one
requires no feeding and there’s no mess to clean up!

The Bluebird SL is a pressure gradient large­diaphragm condenser mic that employs an
edge-terminated 6μ pure gold-sputtered mylar
capsule membrane. Bluebird SL employs a
transformerless Class A amplifier circuit to insure the
most accurate and noise-free signal possible, with
minimal distortion and coloration. What you hear at
the input is what you get at the output. The Bluebird
SL’s tonal character makes it an ideal microphone for
recording vocals, drums, electric guitar, piano, and

most acoustic instruments including difficult sources
like saxophones, flutes, and strings.

The Bluebird SL includes a custom shockmount
designed to isolate the microphone body from low
frequency resonance (rumble).
