The Neumann TLM 67 switchable multi-directional studio microphone in pearl grey and nickel is a large-diaphragm omnidirectional, cardioid and figure-8 microphone. The TLM 67 is based on the Neumann U 67. Like the U 67, the TLM 67 incorporates the K 67 capsule. Furthermore, the circuit design faithfully reproduces the sonic characteristics of the U 67, without the use of valves. It features three switchable polar patterns, a selectable 10 dB pre-attenuation and a high-pass filter that allows detailed adjustments to suit the specific recording situation.

Thanks to its control functions, the TLM 67 is suitable for a wide range of applications. In addition to its primary role as a vocal microphone for all types of music and spoken voice, in orchestral recordings the TLM 67 can be used as a main microphone and as a spot microphone for individual instruments.

The microphone is side-addressed. A large mesh metal grille surrounds the elastically mounted dual-diaphragm capsule. The polar patterns can be selected via a switch located beneath the grille. The selected setting is indicated by a symbol displayed in a window above the switch.

In the TLM 67, an electronic circuit is used in place of a conventional output transformer. Like a transformer, the circuit provides good common-mode rejection, effectively suppressing interference signals affecting the balanced signal line. The microphone can operate at sound pressure levels of up to 105 dB without distortion, and has a dynamic range of 94 dB (A-weighted), without using the pre-attenuation switch.

The pre-attenuation switch located at the rear of the microphone can be used to reduce transmission levels by approximately 10 dB. It should only be used when there is a risk of overloading downstream equipment due to very high sound pressure levels. Using the switch does not increase the dynamic range of the microphone, but rather shifts it by 10 dB towards higher sound pressure levels. The other switch located at the rear of the microphone can be used to modify the cut-off frequency of the built-in high-pass filter, to suppress the effects of impact noise and wind, or to compensate for the proximity effect. The elastic mounting of the capsule provides protection against structure-borne noise transmission.
