Description
NEVATON ORTF– Large Dual-Diaphragm microphone for recordings with the ORTF stereo-system – CURRENTLY UNDER DEVELOPMENT
The Nevaton ORTF is a Stereo Condenser Microphone designed for highly professional ORTF stereo-recordings.
The Nevaton ORTF features large dual-diaphragm capsules and transformerless ‘Class A’ electronics.
The Nevaton ORTF can be used as a main microphone for recording orchestras, chamber ensembles, jazz-concerts, etc. and is also well suited for applications in radio and television broadcasting.
The microphone has an excellent transient response, very low self-noise of only 4 dBA (in cardioid mode) and can transmit sound pressure levels up to 138dB without distortion.
The two large 33mm ultra-thin gold coated diaphragms are made of 3-micron polyethylene-terephtalate film and give the Nevaton ORTF a beautiful and transparent sound. All capsule components have passed a special artificial ageing process to guarantee long-term stability.
The internal construction is elastically mounted to attenuate vibrations and reduce handling noise. Additionally, the capsules are fixed on special dampers to further reduce mechanical noise.
A small LED on the microphone body indicates the presence of 48V phantom power. All input transistors pass a special selection process to guarantee minimal self-noise. The microphone body is made of brass with a dark grey non-reflective paint finish on an epoxy base. A 3-layer metallic grille effectively protects the transducers from electrical and atmospheric interference and contamination from microscopic dust particles. A gold-plated 5-pin XLR-connector in the base mates with the breakout cable (dual 3-pin XLR connectors). The Nevaton ORTF comes with an output cable in a fine hardwood box.
