Product Description

Focusrite ISA One

 is a single channel, transformer-based microphone preamp, based on the original ISA 110 preamp that formed the cornerstone of each channel of the legendary Forte console. It features classic vintage topology and includes the Lundahl L1538 transformer and a custom Zobel network.

The unit contains a line input on XLR and 1/4" TRS phone jacks with the exception of switchable input impedance settings for the microphone preamp. An independent DI channel features a dedicated gain control, active or passive impedance switch, a 1/4" TRS output for routing to an amplifier, and an independent XLR output on the rear.

The ISA One features an insert point should the need arise to place extra signal processing between the preamp or DI, and the optional analog-to-digital converter. Phantom power, phase reverse and a 75Hz, 18dB/octave high-pass filter are also available from the angled front fascia.

Blue BlueBird is a large–diaphragm cardioid condenser, with Blue's renowned microphone technology and Class A discrete circuit. Blue BlueBird's detailed midrange makes most vocals stand out in the mix, and brings out the warmer qualities in brass and higher stringed instruments, while Blue BlueBird's rich low end and clear presence is excellent for acoustic guitars, close-miked percussion, and amplifiers. And at Blue BlueBird's affordable price, you can easily pick up a pair of Bluebirds to capture drum overheads and acoustic pianos in their full splendor.

In addition to the microphone itself, the Bluebird bundle also includes a specially designed shockmount -the BirdCage, and a metal mesh pop filter -the BirdNest. So no matter what your sound, the complete Bluebird package offers today's musician a top-notch recording experience at an outstanding price -all in one nest!
