Multiple POLAR PATTERNS IN ADDITION TO PRE-ATTENUATION AND LOW-CUT FILTER SWITCHES.

NEW Mic Capsule! Replaced capsule by Sennheiser & bought up to spec in 2022 for $875. Not ever used since then. When I was Kenny G's engineer this was his exclusive mic model to record his saxes. I fell in love with this model! This is not the exact mic tho, but I bought it after when I was equipping my studio & HAD to have this Neumann!

FEATURES

- Versatile studio workhorse for vocals and instruments

- High dynamic range: 130 dB

- Very low self-noise 

- Even frequency response for all 5 polar patterns

Applications

The TLM 170 R condenser microphone is a large diaphragm microphone with multiple polar patterns. Its sound has a very transparent characteristic, in contrast to some of our other microphones that have a distinct personality. Therefore, this microphone is used for many diverse applications in professional recording studios, in broadcasting, film and television, and for semiprofessional productions.

Pressure-gradient transducer with double membrane capsule

Five directional characteristics: omni, wide angle cardioid, cardioid, hypercardioid, figure-8

Patented circuitry for remote and local switching of directional characteristics

Switchable low frequency roll-off and 10 dB preattenuation

Tiltable, elastically suspended bracket mount

The Neumann 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 48 R-2 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. Originally built 1985 S/N #1419 . Capsule replaced 2022 then stored away.

Applications

The TLM 170 R condenser microphone is a large diaphragm microphone with multiple polar patterns. Its sound has a very transparent characteristic, in contrast to some of our other microphones that have a distinct personality. Therefore, this microphone is used for many diverse applications in professional recording studios, in broadcasting, film and television, and for semiprofessional productions. The polar patterns can be selected either at the microphone itself, or controlled remotely through the special N 48 R-2 power supply.

Acoustic features

The microphone is addressed from the front, marked with the Neumann logo. The large diaphragm capsule inside the headgrille has a very smooth frequency response for all polar patterns over a wide acceptance angle. The curves are flat and parallel to the 0° frequency curve up to 10 kHz within an angle of ± 100°. As a result the TLM 170 R has a very even diffuse-field response for all polar patterns. This is important in a reverberant environment, as more reflections arrive at the microphone from different directions. The acoustic information is not affected in its tonal quality. when recorded by the microphone. This characteristic is achieved without resorting to corrective resonance effects. Therefore, the microphone maintains an excellent impulse response reproducing all transient phenomena of music and speech without any coloration. The capsule is elastically mounted to avoid any structure borne noise that could interfere with its operation.

Polar patterns

In addition to the usual directional polar patterns: omnidirectional, cardioid, and figure-8, we have added a hypercardioid and wide-angle cardioid characteristic. When compared to the standard cardioid pattern, the hypercardioid characteristic suppresses sound from the side more efficiently. The wide-angle polar pattern is especially useful to record large sound sources.

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.
