Sphere Debuts Fab 500 Series Mic Pre

Sphere Recording Consoles, the manufacturer who came to prominence in the 1970s with studio consoles that were used on iconic recordings by the Rolling Stones, Boston, and many others, has had a rebirth with new owner Duncan Rowe at the helm. At the 2017 Summer NAMM Show, Sphere showed the Fab 500, a 500 Series-format microphone preamplifier. The Fab 500 will be available directly from Sphere at the end of August.

“We were blown away by the attention the Fab 500 received at Summer NAMM,” says Rowe. “People are aware of the Sphere console sound from albums like Some Girls and tons of classic ‘70s R&B. The first and most important aspect of that sound is the mic preamp, and the Fab 500’s design is completely true to the original circuitry of the Sphere consoles. We’re proud to now offer it in a 500 Series format as well as a four-channel rackmount version with the Fab Four.”

The Fab 500 is a single channel microphone preamplifier compatible with the 500 Series format. It offers 56.6dB of total gain, with a frequency response of 12Hz to 56kHz. It features two attenuation pads at -15dB and -30dB, making it useful for even high SPL sources. The Fab 500 also includes switchable +48V phantom power and a phase switch.

Originally formed in the early 1970s, Sphere was founded by the owner and chief engineer of Electrodyne consoles. Best known for their incredible sounding mic pres and their musical EQ’s, Sphere manufactured a full line of semi- and fully-custom audio consoles for both recording studios and performance venues continuously for many years. The Fab Four and Fab 500 Series are exact replicas of the original Sphere mic pres (including the same input and output transformers, and proprietary op amp). Featuring a big, open sound with tons of headroom, these preamplifiers can be a go-to choice for drums, bass, vocals, amplifier cabinets, and much more.
