<h1> SE Electronics RNR1 Active Ribbon Microphone</h1>
The sE Rupert Neve RNR1is the World's First HF Active Ribbon Mic. For many decades ribbon mics have been used by engineers for their extremely natural sounding reproduction of source material. The nature of their performance differs greatly from condenser mics, which by comparison sound very 'up front' and lack the harmonic depth of a good ribbon.
<br/><br/>
Even at the high end of the market, the customary roll-off of almost all the top end frequencies has always been a major drawback. The frustration with all ribbons is - depending on the model - little or no performance past 7-10KHz, which is why condenser mics dominate the recording market.<br/><br/>
The traditional appeal of the condenser then has been the assumption of consistent frequency response from 20Hz to 20KHz. The pay-off of course is that these mics require a certain degree of circuit board magic to achieve this, since the taughtness of the diaphragm - compared with relatively slack ribbon membranes - means condensers tend to be more 'coloured' in their sound.<br/><br/>
Traditionally engineers using ribbons, however expensive, have had to accept their significant limitations or have had to augment the recording with a condenser mic to capture the high frequency absent from the ribbon output.<br/><br/>
Such compromises have meant that ribbons have never been very widely accepted or used as a first choice for recording.<br/><br/>
<h3>Custom Transformers</h3>
Nobody knows audio transformers better than Rupert Neve, and ribbon mics require more transformer attention than any other. This is because the transformer that couples the ribbon to the output needs to accomplish a fairly massive impedance conversion.
<br/><br/>
With the RNR1, two custom Rupert Neve-designed transformers form the buffer between the ribbon and the outside world. The circuitry between those transformers helps maintain the ultra-wide frequency response, compensating for the ribbon's natural predisposition to roll it off, and thus high-frequency content is preserved.

<h3>The Ribbon</h3>
During the RNR1's development, a full year was spent working on crafting a ribbon element that would provide the extended response that Mr. Neve demanded.
<br/><br/>
After experimenting with ribbon materials available from all corners of the world, the design team landed on the 2.5µm aluminum ribbon used in the RNR1, striking the perfect balance of flexibility and stiffness needed for this microphone's exceptional performance.<br/><br/>
<h3>Precision Machine Body</h3>
As with many sE microphones, the RNR1 has an unusual and bold design aesthetic, with the form following the function.
<br/><br/>
The precision-machined and scalloped edges don't just look vibrant and dramatic, they have also been custom-designed to provide the ribbon with an acoustically ideal setting for the best possible frequency response.<br/><br/>
<h3>Matte Black Finish</h3>
The matte black finish means the mic remains unobtrusive and doesn't draw any unnecessary attention to itself under harsh stage or studio lighting.
<br/><br/>
<h3>Custom Shock Mount</h3>
The RNR1 includes a custom-designed and easy-to-use shock mount, which is essential in use to reduce the unwanted effects of vibration or knocks to the supporting microphone stand.
