SONTRONICS Helios (Valve) Condenser Mic

The Sontronics Helios is a warm dual-diaphragm valve mic with dedicated low-noise power-supply. Beautifully-crafted including flight-case.

The Sontronics Helios is a smooth and warm valve mic cast in zinc alloy for ultra-low resonance. The 35mm dual-diaphragm capsule is floated within a large-grill spherical basket to improve high-end frequency capture. Twinned with the valve circuitry, this results in crisp high-frequency capture, whilst maintaining an accurate low-end response.

The Sontronics Orpheus comes supplied in a wooden box and flight-case, dedicated low-noise power-supply and dedicated mic clip. It also benefits from Sontronics Lifetime Warranty covering component or manufacturing defects.

Also available as a solid-state version.
