sE Electronics RNT Multi-Pattern Tube Condenser Mic on Vocals

In this video, Sound Pure pro audio specialist Chuck Giardino runs us through the sE Electronics RNT Multi-Pattern Tube Condenser Microphone with a little help from our very own Michael Buckley on vocals. In this demo, Michael sings "Confession," a song he wrote and recorded with his band Ekiim Ariara, for their 2015 debut album, "Dead Man's Song" (available now on iTunes, Spotify and Bandcamp).

Manufacturer's Description from sE

The RNT is the third microphone in the collaboration between sE Electronics and Rupert Neve Designs, founded by the legendary audio designer Mr. Rupert Neve. Much like the RNR1 Active Ribbon and RN17 Small-Diaphragm Condenser, the RNT is something truly special, developed over several years of careful listening and measurement by Mr. Rupert Neve, Mr. Siwei Zou, and the engineering teams from both Rupert Neve Designs and sE Electronics. All in all, this new flagship tube microphone brings the larger-than-life sounds of classic studio microphones into the modern age with greater depth and clarity than ever before.

The RNT utilizes fully discrete, Class-A electronics throughout both of its active stages. The first stage is tube-based, with a hand-selected, low-noise ECC82 tube within the microphone chassis, and implementing a custom-built Rupert Neve Designs output transformer. The second stage is within the floor box – which also controls polar pattern, filter and gain switching – and is built around the same custom op-amps used in Rupert Neve Designs’ flagship 5088 recording console, known worldwide for its unrivaled transparency and headroom. This second stage is also coupled with a second custom-made Rupert Neve Designs output transformer.

The custom handcrafted large-diaphragm true condenser capsule is sE’s finest capsule yet, born from years of rigorous testing and listening, and developed and constructed by hand in sE’s own factory. The Class-A electronics and switchable gain ensure a massive dynamic range, with high sound pressure level (SPL) handling capability and extremely low-noise components, and the switchable low-cut filters eliminate rumble or footfall noise, and can also compensate for an excess of bass frequencies caused by the proximity effect. This enables the RNT to close-mic many instruments including electric guitar speaker cabinets, brass instruments, and drums. Lastly, the 9-position polar pattern switch allows for omnidirectional, cardioid, and figure-eight pickup patterns - and several positions in between each – for precise tailoring of the balance between direct and ambient sound when recording with the RNT. Reliable operation is ensured by the sturdy all-metal design, robust construction, and high- quality manufacturing standards. A high-quality metal case is also included.

About Manufacturer

The sE Electronics story begins withMr Siwei Zou, a hugely talented classical musician from Shanghai who won a top place at the Shanghai Conservatory and went on to become a highly successful player, conductor and composer. He worked closely with the Shanghai Opera and the Shanghai Philharmonic Orchestra as both conductor and recording artist,with several hugely successful classical hit recordings to his name. In 1987 he was invited by California Sonoma State University as a visiting Scholar to serve on the faculty. He continued to teach counterpoint and orchestration as a faculty member in the Music Department at the University. He also studied recording technology under Grammy Awards nominee Professor Warren Dennis Kahn. The sE commitment to exceptional quality can be directly attributed to the company founder Mr. Zou, who in his distinguished career has developed an ingrained instinct and desire for perfection. Wishing to bring this drive for artistic and creative perfection to bear in a tangible way, Siwei started his own microphone manufacturing company. Working with a team of his own top engineers, and experts in the field of electrical engineering at Shanghai University, Siwei designed, built and tested a whole range of new and innovative products. Shunning the common practise of western manufacturers re-branding cheap Chinese microphones, Siwei designed and built his own range of microphones which are now manufactured in his state-of-the-art facility in Shanghai., the ultra-modern face of new China. sE Electronics make only their own products, which means dedication to detail in every aspect of performance and styling without compromise. All sE mic capsules are entirely built by hand. Even the chassis and flight cases are built in-house. In fact when you own an sE microphone you can be confident that every aspect of both the mic and its accessories has had the same unrivalled level of care and passion right throughout its design and manufacture. Even to the level that every single microphone that leaves the facility has undergone a personal listening test rather than simply being put through a machine - and it shows. Launched in Europe in 2003, sE Electronics condenser mics are now the number one brand in the UK and the fastest growing microphone brand in Europe. The brand, in its short history, has already won almost every major European award possible for excellence including the Future Publishing Readers Poll ýMic of the Yearý Award. Although sE is a new line to the USA in 2004, both the sE Gemini and Icis have already won the coveted ýMix Certified Hitý Award and the range is fast finding the same unanimous acclaim and passionate following that it has in Europe. sE is so confident youýll be able to really hear the difference, that they offer a completely free loan service for all of their products! The range includes three superbly tailored ýpencilý instrument mics, two large diaphragm solid-state condensers, two incredible performance tube mics, and the worldýs first dual tube, transformerless, studio mic in the form of the award-winning Gemini.
