The TLM 103 is a cardioid microphone with a large-diaphragm condenser capsule derived from the classic K67/87 capsule of the legendary Neumann U 87. However, the TLM 103 has a slightly more modern voicing with a wide presence boost for frequencies above 5 kHz.

Its very direct yet refined sound is perfect for vocals and solo instruments that pop out of the mix without effort. Of course, the TLM 103 also has the famous authoritative midrange that has become the hallmark of Neumann microphones and made them a top choice in studios around the world. A special feature of the TLM 103 is its impressively deep yet controlled low end, perfect for sonorous voices and powerful bass instruments.

With an incredibly low self-noise of only 7 dBA, the TLM 103 is among the quietest microphones available. And its high sensitivity of -32.5 dBV ensures ultralow noise, even with budget preamps and audio interfaces or vintage tube equipment. At the same time, the TLM 103 can handle enormous sound pressure levels of up to 138 dB without the need for pre attenuation. Its vast dynamic range of 131 dB makes the TLM 103 a very easy-to-use studio microphone as it will capture anything from a soft whisper to a thunderous bass drum without adding noise or distortion.

As a member of Neumann's TLM series, the TLM 103 works with a transformerless output stage, which minimizes transmission losses and ensures a very immediate, uncolored sound, true to the original as well as a clear, powerful bass response, even at highest signal levels.

The TLM 103 was primarily designed for project studios and broadcast use, but due to its outstanding performance was soon embraced by renowned studios as a more modern sounding alternative to the U 87 for speech, vocals, drums, guitar amps, and piano. The TLM 103 is also often used as a spot mic in classical recordings for cello and double bass.
