When it comes to capturing the nuances of sound with precision, ribbon microphones are one of the best options out there. Among the variety of ribbon microphones available, the Sontronics SIGMA 2 and DELTA 2 microphones are often celebrated by professionals and enthusiasts alike. While both models share a common lineage, they each serve distinct purposes, catering to different needs within the realm of audio recording. In this blog, we’ll explore the key differences between the Sontronics SIGMA 2 and DELTA 2, helping you determine which microphone is best suited for your specific application.
Sontronics’ Ribbon Microphones
Sontronics SIGMA 2: A Symphony of Sensitivity and Detail
The Sontronics SIGMA 2 is an elegant, phantom-powered ribbon microphone that exudes vintage charm in both appearance and sound. This microphone has carved out a niche for itself in studios and live venues around the world, renowned for its high sensitivity and low self-noise. The SIGMA 2 delivers a level of intimacy in its recordings that is perfect for capturing the subtleties of vocals, solo woodwind and string instruments.
Key Features:
-
Ribbon Microphone with Phantom Power:
Unlike traditional ribbon microphones that don’t require phantom power, the SIGMA 2 uses it to deliver enhanced performance, making it more versatile and compatible with modern audio interfaces, preamps and mixers.
-
High Sensitivity, Low Noise:
The SIGMA 2’s 18mV/Pa sensitivity and low self-noise of 10dB (A-weighted) mean it captures even the quietest of details with precision, providing a clear and natural sound without unwanted background noise.
-
Wide Application:
Whether you’re recording vocals, solo instruments, or amplifiers, the SIGMA 2’s figure-of-eight polar pattern and frequency response of 20Hz to 15kHz ensures a balanced and true-to-life sound.
-
Vintage Aesthetics with Modern Capability:
The SIGMA 2 is as much a visual delight as it is an auditory one, with a design that harks back to the golden age of ribbon microphones while offering modern-day functionality and reliability.
Sontronics DELTA 2: Rugged Precision for Powerful Performances
The Sontronics DELTA 2 is engineered for a different kind of performance—one that requires the microphone to handle high sound pressure levels (SPL) without compromising on the ribbon microphone’s characteristic warmth and detail. This rugged ribbon microphone is a favourite among guitarists, brass players and live sound engineers for its ability to capture the full intensity of loud sound sources like guitar amps, brass instruments and saxophones, all while maintaining clarity and reducing the chances of distortion.
Key Features:
-
Designed for High-SPL Environments:
The DELTA 2’s ability to handle SPLs up to 140dB makes it ideal for use with loud instruments that would overwhelm other ribbon microphones due to its internal pop-filtering and increased head-room from the transformer. This feature is crucial for capturing the dynamic range of powerful sources like guitar amplifiers and brass sections.
-
Durability Meets Detail:
Constructed to withstand the rigours of live performances, the DELTA 2 combines rugged build quality with the delicate tonality typical of ribbon microphones, making it a versatile tool for both the stage and studio.
-
Phantom-Powered for Enhanced Performance:
Similar to the SIGMA 2, the DELTA 2 also requires phantom power, which enhances its performance capabilities, making it more adaptable across different recording environments.
-
Favoured by Professionals:
The DELTA 2’s reliability and precision have made it a go-to choice for artists and engineers who need a microphone that can deliver consistent results in demanding settings. The microphone’s rugged design ensures it can handle the wear and tear of frequent use while still delivering the high-fidelity sound that professionals demand.
Comparing the SIGMA 2 and DELTA 2: Which Ribbon Microphone Right for You?
While both the SIGMA 2 and DELTA 2 offer the signature warmth and intimate tone associated with ribbon microphones, their design and application set them apart.
Sensitivity vs. Strength:
The SIGMA 2 is all about capturing delicate, nuanced performances with incredible sensitivity and low noise, making it ideal for quieter, more detailed sources like vocals and solo instruments. On the other hand, the DELTA 2 is built to handle the intensity of loud sound sources without distortion, making it perfect for electric guitars, brass instruments and live performances.
Aesthetic vs. Application:
The SIGMA 2’s vintage aesthetic and versatile application in studio environments make it a favourite for those looking to capture the essence of classic ribbon microphone sound. Meanwhile, the DELTA 2’s rugged build and ability to withstand high SPLs make it indispensable for musicians and engineers who need a microphone that can deliver under pressure, whether on stage or in the studio.
Versatility vs. Specialisation:
If your work primarily involves recording a wide range of instruments, especially in quieter and professional settings the SIGMA 2’s versatility and high sensitivity make it an excellent choice. However, if your focus is on capturing powerful performances from electric guitars, brass and similar instruments, the DELTA 2’s specialised design will serve you better.
Both the Sontronics SIGMA 2 and DELTA 2 represent the pinnacle of ribbon microphone technology, each excelling in their respective fields. The choice between the two ultimately comes down to your specific needs as a musician, producer or engineer. If you need a microphone that offers vintage charm with modern versatility, the SIGMA 2 is the way to go. But if your work demands a microphone that can handle high SPLs without sacrificing detail, the DELTA 2 is your best bet.
Whichever you choose, you can be assured of Sontronics’ commitment to quality and precision. Both microphones offer a unique blend of performance, durability and sonic excellence, ensuring that your recordings will stand out in any context.
