With its advanced design tailored for professional audio capture, the Electro-Voice RE90B Half-Cardioid Condenser Boundary Microphone stands out in the RE Series Architectural Microphone Group. This high-performance microphone is meticulously engineered with Electro-Voice's exclusive RF Shield technology, ensuring exceptional shielding from radio frequency interference (RFI) and GSM signals, which is crucial for maintaining audio clarity in today's digitally connected world.
The RE90B is a versatile full-range condenser microphone, ideal for a variety of surface-mounted applications, including distance learning centers, video conferencing systems, teleconferencing setups, and sound reinforcement tasks. Its half-cardioid (half-space cardioid) polar pattern is specifically designed to provide excellent gain-before-feedback and to effectively suppress unwanted ambient noise, making it a reliable choice for environments where audio quality cannot be compromised.
One of the unique features of the RE90B is its ability to counteract the baffle effect, which typically results in increased microphone sensitivity at higher frequencies when operated on a flat surface. This is achieved through carefully crafted internal equalization, which ensures a flat sensitivity response across the frequency spectrum for consistently clear and balanced audio reproduction.
The microphone is thoughtfully designed to be powered by an external 9-52 VDC phantom power supply, conforming to DIN 45 596 standards, which provides flexibility and compatibility with a wide range of audio systems.
Durability is also a key aspect of the RE90B, with its robust zinc die-cast body and a protective perforated steel screen designed to withstand the rigors of frequent use. The microphone's housing serves dual purposes: it is electronically isolated from the mounting surface to prevent interference, and it offers discreet cable management options. The miniature cable can be routed from the rear or through the bottom of the microphone for a clean, professional installation.
For added security, the RE90B features a pilfer-resistant internal terminal block, ensuring that the microphone remains securely connected at all times. A drilling template is included for precise and hassle-free permanent installations.
The low-profile design of the RE90B's body is not only aesthetically pleasing but also functional, with shock-mounting achieved through a combination of a heavy diecast case, a rubber non-slip bottom pad, and internal padding for both the microphone and the printed circuit board. This multi-layered isolation approach effectively minimizes the transmission of surface vibrations to the microphone, ensuring that only the intended audio is captured.
The RE90B is equipped with a 3.0-meter (10ft.) white miniature shielded two-conductor cable, terminating in a male XLR-type connector, providing both reach and high-quality signal transmission for professional audio setups. Whether used in educational, corporate, or entertainment settings, the Electro-Voice RE90B microphone delivers exceptional audio performance with an elegant and discreet presence.
