The first Neumann mic with transformerless technology, featuring 5 directional characteristics, selectable at the mic or remotely, in addition to pre-attenuation and low-cut filter switches. The excellent sound pressure handling capability makes this mic ideal for recording wind instruments, for example.
The TLM 170 R was the first microphone to use the successful fet 100 technology. Along with a balanced, transformerless output stage it features extremely low self-noise and an impressive dynamic range.
Five directional characteristics are selectable by means of a rotary switch. In the sixth position, marked "R", the directional patterns can be controlled remotely with the N 248 power supply. There is no special cable necessary for this purpose.
The microphone has at its rear a 10 dB attenuation switch for extremely high sound pressure levels, and a high-pass filter to suppress structure born noise.
