The Sontronics OMNI-S is a dedicated, interchangeable omnidirectional capsule designed specifically to expand the capabilities of the highly regarded Sontronics STC-1 and STC-1S small-diaphragm condenser microphones. This clever accessory allows audio engineers to instantly transform their standard cardioid pencil microphone into a completely different recording tool. Featuring a simple and highly secure screw-on mechanism, users can effortlessly unthread the original capsule and replace it with the OMNI-S mid-session, radically altering the mic's acoustic pickup pattern to suit different recording environments.
By switching to an omnidirectional polar pattern, the Sontronics OMNI-S completely opens up the microphone's field of hearing, capturing sound equally from all 360 degrees. This provides an incredibly natural, open, and immersive audio experience, making it the perfect choice for capturing the organic ambiance and reverberation of a live recording space. Because omnidirectional capsules lack the proximity effect inherent in directional mics, it allows for highly flexible positioning—you can place the microphone much higher up or further away from the sound source. It is an invaluable asset when tracking expansive sources like choirs, symphony orchestras, brass ensembles, and grand pianos.
When fitted to a matched pair of STC-1 microphones, the OMNI-S capsules create a stunning stereo room or overhead pair for drum kits, granting recordings a true "in-the-room" sense of depth, space, and reality that cardioid patterns cannot achieve. Built to the exacting quality standards expected of Sontronics’ British engineering, the capsule ensures pristine, transparent audio capture across the entire frequency spectrum. The 'S' model features a classic silver finish, designed to seamlessly color-match the silver editions of the STC-1 microphone line.
