The Electro-Voice TM15 is a versatile and high-performance transmission line microphone that delivers exceptional sound quality for live sound applications. At its heart is a 15-inch dynamic speaker element, which features a 25 ohm voice coil and a 70.7 volt transformer coil.
The transformer coil plays a crucial role in the microphone's operation, as it steps up the voltage from the low-level output of the dynamic element to a level suitable for transmission through long cables to the mixing console. The TM15's 70.7 volt transformer coil is designed to provide optimal performance and reliability, ensuring that the microphone delivers clear and accurate sound even over long distances.
The voice coil, with its 25 ohm impedance, is optimized for use with modern mixing consoles and power amplifiers. This impedance level is standard for many modern sound systems, making the TM15 a seamless addition to any setup. The use of a high-quality voice coil ensures that the microphone delivers consistent and powerful sound, even when pushed to its limits.
The Electro-Voice TM15 transmission line microphone is a professional-grade tool for live sound applications, offering exceptional sound quality, reliability, and versatility. Its 15-inch dynamic element, combined with the high-performance transformer and voice coil, delivers clear and accurate sound, making it an ideal choice for use in a wide range of live sound environments, from small clubs to large arenas. With its rugged construction, the TM15 is built to withstand the rigors of live performance, ensuring that it continues to deliver superior sound quality night after night.
