The Sontronics DELTA 2 is a revolutionary phantom-powered ribbon microphone, expertly designed and hand-built in the UK. As the highly anticipated successor to the original Delta—the world’s first ribbon microphone designed specifically to handle extremely loud sources—the DELTA 2 has become the industry standard for miking guitar amplifiers and brass instruments. It delivers all the intimate tone, warmth, and subtlety characteristic of classic ribbon designs, while boasting the ruggedness to capture powerful signals up to 140dB SPL without ever overloading or clipping.
Unlike fragile vintage ribbon microphones, the Sontronics DELTA 2 features an active preamp circuit powered by standard 48V phantom power. Combined with custom-wound UK transformers, this setup guarantees a remarkably high output signal with an incredibly low self-noise floor of just 10dB. A massive innovation in the DELTA 2 is the inclusion of built-in RFI (Radio Frequency Interference) filters that actively reject unwanted buzz and interference from stage electronics, making it a flawlessly reliable choice for both high-end studio recording and demanding live tours.
Utilizing a true figure-of-eight polar pattern, the microphone captures the direct punch of your amp from the front while recording natural room ambiance from the rear. Its perfectly tailored frequency response accurately reproduces every detail of your instrument's tone, ensuring tracks sit perfectly in a dense mix without requiring excessive EQ tweaks. Supplied in a rugged, foam-padded ABS flightcase, the DELTA 2 also includes a uniquely designed custom shockmount to actively isolate the microphone from floor vibrations and handling noise.
