Sontronics OMEGA cardioid valve condenser microphone

SONTRONICS OMEGA cardioid valve microphone
Not currently in production but still available on the second-hand market, Sontronics OMEGA is a valve/tube condenser microphone with a fixed cardioid polar pattern, designed to give stunning results on vocals and instruments.

Sontronics OMEGA has a carefully hand-finished, gold-sputtered capsule suspended in its lollipop-style grille head, and this along with its unqiue Sontronics-designed circuitry allow it to combine rich, warm low frequencies with natural highs.

The resulting sound is extremely satisfying and, we're told, utterly addictive, and OMEGA is a must-have for many producers and studios.

"I work with a lot of vocalists and honestly nothing works as well with everyone as the OMEGA. It has a true, honest sound with crispy, in-your-face boosts at the top.
It's beautiful… I use it every single day. OMEGA is the best all-round microphone that everyone can afford!"

MATIAS LEHTOLA, Producer/Artist/Lecturer

Sontronics OMEGA (like our HELIOS with its continuously variable polar pattern) houses a hand-selected 12AX7/ECC83 vacuum tube. The microphone comes with its own dedicated power supply unit, the SPS-2, which features a 75Hz low-cut filter and a -10dB attenuation pad.

The SPS-2 also gives you the option to switch between 115V and 230V, depending on where in the world you are using your microphone.

"OMEGA has such a warm, rich sound… it could
become a real workhorse in any studio"

HAYDN BENDALL, Reviewer/Producer (Pro Sound News Europe)

Our Sontronics OMEGA microphone comes in a velvet-lined wooden box and this is packaged together with its spider-style shcokmount, spare shockmount elastics, the SPS-2 power supply unit and all required cables in a rugged aluminium flightcase.

Although OMEGA is not currently in production, if you do find one on the second-hand market, grab it quickly as these are extremely desirable microphones! If you want to take an even higher step up the valve microphone ladder, try our multi-award-winning ARIA valve condenser microphone, which does everything the OMEGA could do but even more amazingly!


PLEASE NOTE: Sontronics OMEGA is not currently in production. If you have any queries about your own OMEGA or you are looking to purchase a second-hand OMEGA, please contact us.
