Neumann TLM 170 R MT

The TLM 170 R is a truly universal microphone for even the most demanding recording situations. It combines technical excellence with the smoothness and flexibility of a large diaphragm capsule. The TLM 170 R offers an exceptionally even response in five directional patterns. The latter may be remote controlled via the optional N248 PSU.

A MILESTONE IN MODERN RECORDING The TLM 170 R may be our most universal microphone. Over an enormous dynamic range it offers a remarkably linear frequency response, both on- and off-axis, in each of its five polar patterns. Thus, the TLM 170 R is able to capture the natural sound of any source, including its room ambience, without imparting a sonic imprint of its own. Additionally, the microphone's directionality may be remote controlled via the optional N248 PSU.

AHEAD OF ITS TIME The TLM 170 R was conceived with high resolution in mind. As early as 1983 it achieved an enormous dynamic range of 130 dB. It was the first microphone to use Neumann's fet 100 technology with a transformerless output stage ensuring sonic transparency and powerful bass transmission, even at highest signal levels.

Its sonic transducer is no less impressive. The K89 dual diaphragm capsule offers high linearity in every sense: smooth frequency response, fast transient response, and frequency independent polar patterns. Even the diffuse field response remains uncolored for all polar patterns, which is crucial in reverberant environments.

Electrical features The letters TLM stand for transformerless microphone. With TLM technology the usual output transformer is replaced by an electronic circuit. As with traditional transformers, it ensures good common mode rejection, and prevents RF interference, that may influence the balanced audio signal.
