The R 1 TUBE ACTIVE is like a missing link of true old-school vintage recording in that it combines three vintage elements:
- A classic ribbon transducer.
- Two transformers.
- A tube buffer amplifier.
You might think that a ribbon, transformers and a tube amplifying stage will make the signal too smooth?
It´s true that the sound of the R1 Tube Active is truly warm and fat, but the combination of the tube stage and the transformers will generate overtones that makes the signal come alive.
If you are into mics, if instant no-need-to-mix good-sounding recording is your thing, if you are looking for a unique yet versatile mic, this is it! |

| Behringer C-1 Studio Condenser Microphone
Behringer C-1 Studio Condenser Microphone
The C-1 Studio Condenser Microphone from Behringer offers a cardioid pickup pattern for maximum sound source separation and feedback rejection. This low noise microphone is suitable for a wide range of recording scenarios, including project, professional, and home studio applications. There is a pressure gradient transducer and a shock-mounted large diaphragm capsule for open, transparent sound with high-quality transient response. It is constructed of a die-cast metal body for durability and features an LED light to indicate when the microphone is receiving phantom power. The C-1 includes a swivel mount and custom case.
- Professional large-diaphragm condenser microphone for unsurpassed audio quality
- Ideal as main and support microphone for studio and live applications
- Exceptionally flat frequency response and ultra-high sound resolution
- Cardioid pickup pattern for outstanding sound source separation and feedback rejection
- Ultra low-noise transformerless FET input circuitry
- LED indicates phantom power operation
- Gold-plated 3-pin XLR output connector for perfect signal transmission
- Ultra-rugged construction with die-cast body
- Swivel stand mount and carrying case included

| The C 414 B/XLS has been carefully designed to maintain the legendary sonic character of the C 414 family while integrating new features and performance enhancements made possible by new technology. The C 414B/XLS is designed to deliver accurate pickup of all acoustic instruments and voices.
The microphone's 5 pickup patterns are easily selectable via an electronic switch with LED indication and offer the selection of omnidirectional, cardioid, wide cardioid, hypercardioid and figure-eight patterns.
The pickup pattern selector switch utilizes a dual-color LED indicator that provides visual indication of the pattern selected and also changes from green to red to indicate if the microphone's output electronics are being overloaded. The pattern selector can also be used to "lock" the microphone's switch settings by pressing and holding it for 3 seconds.
On the rear of the microphone, an electronic switch allows the selection of -6 dB, -12 dB and -18 dB pre-attenuation levels which are accomplished by changing the polarization voltage to the capsule. The C 414 B/XLS has switchable bass cut filters of 12 dB-per-octave at 40 Hz and 80 Hz, and a 6-dB-per-octave filter at 160 Hz for control of proximity effect. On-axis sensitivity for all patterns is 23 mV/Pa and its self-noise is an extremely low 6 dB-A.
The C 414 B/XLS has a transformerless output and all-metal chassis, making it immune to electrical interference and RF from digital equipment, video monitors and wireless systems. It comes complete in an all-metal road case with the AKG H-85 shock mount, a PF80 external two-stage pop filter, a W414X external windscreen and an individually-measured chart showing the response curve of the microphone. It is also available in factory-matched stereo pairs packaged with a H50 stereo bar instead of the external pop filter.
The C 414B/XLS is built in Vienna, Austria and comes with a three-year limited parts and labor warranty.
