Description
The Neumann TLM 103 cardioid condenser microphone brings the coveted Neumann sound into the home and project studio. It combines a capsule based on the famed K 87 with a transformerless design, providing ultra-low self-noise and high SPL tolerance up to 138 dB. The result is platinum sound at a bronze price.

Neumann TLM 103 Condenser Microphone Main Features
- Large-diaphragm cardioid condenser mic for studio and broadcasting applications
- Transformerless circuit delivers incredibly low self-noise
- Capsule based on the K 87, known from the U 67 and U 87 mics
- 138 maximum SPL, 20Hz–20kHz frequency response

Cardioid Pattern for Better Isolation and Clarity
- Like many of the most coveted studio mics, the Neumann TLM 103 contains a large-diaphragm capsule in a cardioid polar pattern. The TLM 103 is addressed from the front, marked with the red Neumann logo on the microphone body. The cardioid pattern avoids picking up any noise from the back, isolates the main source and renders slightly off-axis sounds naturally. It also helps prevent feedback in the studio and (most crucially) on stage.

High-Performance Capsule Delivers True Neumann Sound
- The K 103 large-diaphragm capsule is based on the K 87, well known from the U 67 and U 87 microphones that sell for multiple times higher. The capsule has a flat frequency response up to about 5kHz, and above that, a wide, flat 4 dB presence boost. The large wire mesh cover protects the capsule from plosive sounds and prevents pop noises. These characteristics are achieved with the hardware, without resorting to corrective resonance effects. Therefore, the microphone maintains an excellent impulse response and reproduces the finest details of music and speech without coloration.

Transformerless Technology Reduces Self-Noise
- The letters TLM stand for "transformerless microphone.” Using TLM technology, Neumann replaced the usual output transformer with an electronic circuit. Like a traditional transformer, this circuit ensures good common mode rejection and prevents RF interference. With just 7 dB-A and 17.5 dB CCIR, the self-noise level of the TLM 103 is so reduced that even the smallest signals are reproduced basically noise-free. Since the mic is capable of handling sound pressure levels up to 138 dB without distortion, the TLM 103 provides a dynamic range of 131 dB (A-weighted). The result is genuine Neumann sound at a significantly reduced cost.
