Neumann TLM 170 R-MT-STEREO (MATT BLACK) / TLM 170 R-STEREO (NICKEL) Factory-matched

Neumann TLM 170 R-MT-STEREO (MATT BLACK) / TLM 170 R-STEREO (NICKEL) Factory-matched stereo set of two TLM 170 R mt / two TLM 170 R with EA 170 mt in Mic Briefcase

The Neumann TLM 170 R-MT-STEREO comes in matt black while the TLM 170 R-STEREO is in nickel color. This is a Multi-Pattern Large-Diaphragm Studio Condenser Microphone from Neumann, that is a stereo set of two large-diaphragm, multi-pattern condenser microphones that comes featuring FET 100 technology, a balanced, transformerless output stage, low self-noise, and an impressive dynamic range.

Five directional characteristics are made selectable through the use of a rotary switch. In the sixth position, marked "R," the directional patterns is capable to be controlled remotely using the included N 248 power supply. This purpose is not requiring any special cable. The microphone comes at its rear a 10 dB attenuation switch for extremely high sound-pressure levels, and a high-pass filter for suppressing structure-borne noise. A second switch at the rear is made for enabling the mic for attenuate the frequency response below 100 Hz for suppressing undesired structure-borne noise.

The TLM 170 R is capable to be used for many diverse applications in professional recording studios, in broadcasting, film and television, and for semi-professional productions.

The large-diaphragm capsule inside the head grille comes with 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.

The microphone is designed for maintaining an great impulse response reproducing transient music and speech without any coloration. The capsule is elastically mounted for avoiding any structure-borne noise that could interfere with its operation.

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. The N 248 controls the polar pattern remotely by varying the phantom voltage. The range is ± 3V of the nominal 48V value. The rotary switch on the microphone must be in the position R, remote control. In this switch position the TLM 170 R microphone analyzes the absolute value of the phantom power and selects the corresponding polar pattern. A standard 3-pin microphone cable is used, similar to the microphone's conventional operation. Cable lengths may be up to 1000'.

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.

A tilting side bracket is intended for attaching the microphone to booms or stands is included. The bracket is equipped with rubber elements that effectively protect the microphone from mechanical shock. If necessary, it can be mounted on the other side of the microphone as well. When using the IC 4 cable, the bracket and its holder need to be removed. The microphone can then be connected to the swivel-mount connector of the cable.

All exposed surfaces of the capsule, including the diaphragms, are at ground potential. This technology makes them highly immune to electrical and atmospheric interference and contamination through dust particles.
