As part of the recent advancements to its Engineered Sound® line, Audio-Technica has updated the ES945 Omnidirectional Condenser and ES947 Cardioid Condenser “button” Boundary Microphones. Developed in direct response to requests from leading contractors and acoustical consultants, the ES945 and ES947 boundary microphones offer outstanding speech intelligibility and transparent sound quality for surface mount applications such as conference tables, residential monitoring, in houses of worship, in theater applications and other demanding sound pickup applications.
Employing Audio-Technica’s proprietary UniGuard® technology, both models offer complete immunity to radio frequency interference (RFI), making them perfectly suitable for operation in environments congested with portable communications devices. Featuring a low-profile design with robust construction, the ES945 and ES947 boundary microphones are available in a low-reflectance black or white (ES945W/ES947W) finish, plus can be painted allowing contractors to offer customers a high-quality, low-profile audio solution that blends into any décor. With superior off-axis rejection and maximum gain-before-feedback, these professional microphones set audio-quality standards in the most challenging acoustic environments. In addition, the ES945 and ES947 microphones are also fully RoHS-compliant — free from all substances specified in the EU directive on the reduction of hazardous substances.
The ES945 is a wide-range condenser microphone with an omnidirectional polar pattern, has a frequency response of 40 Hz to 18,000 Hz, accepts a maximum input sound level of 142 dB SPL and measures a mere 1.10" in diameter. The ES947 is a wide-range condenser microphone with a unidirectional polar patter, a frequency response of 40 Hz to 12,000 Hz, can accept a maximum input sound level of 142 dB SPL and measures a maximum diameter of 1.18". Both models feature a heavy-duty die-cast case while a two-layer steel mesh grill adds additional protection.
The ES945 and ES947 are part of Audio-Technica’s Engineered Sound line that is available only to the professional installed sound market via a network of specialized sound contractors and system integrators as opposed to retail outlets. Ideal for installation in churches, boardrooms and government meeting rooms, courtrooms, distance-learning facilities and other corporate installations, the Engineered Sound line exemplifies A-T’s commitment to offering the fixed installation/sound contracting market the highest performance products, offering RoHS compliance, full UniGuard RFI immunity, and the ability to meet international specifications.
The updated ES945 Omnidirectional Condenser Boundary Microphone and ES947 Cardioid Condenser Boundary Microphone are available in June 2007 with suggested list pricing as follows:
ES945 & ES945W $210.00
ES947 & ES947W $225.00
