NEUMANN TLM 127 Dual Diaphragm Condenser Microphone

This 127 mic is fully functional and in very good condition.

The TLM 127 is a large-diaphragm studio microphone with omnidirectional and cardioid directional characteristics. In addition, via a special power supply it is possible to use remote control to switch between the five directional characteristics: omnidirectional, wide-angle cardioid, cardioid, hypercardioid, and figure-8.  The TLM 127 is addressed from the front, marked with the Neumann logo. On the front of the microphone is also the switch for selecting the directional characteristic.  There are 3 settings: omnidirectional, cardioid, and remote control (”R“).  On the back of the microphone is a 14 dB attenuation switch, as well as a high-pass filter switch with 2 settings: –3 dB cut-off frequency 15 Hz (”LIN“), and 100 Hz.

Applications

The comprehensive control features, which permit optimal adjustment to particular requirements, make the TLM 127 well-suited to a wide range of applications. It is an extremely flexible tool, appropriate for advanced operators of home recording studios as well as for experienced audio professionals who place the highest demands on the sound and technical capabilities of a microphone.

Acoustic Features

When the cardioid setting is used the capsule has a flat frequency response up to 3 kHz and an increased presence of 3 dB at higher frequencies.  The wire mesh headgrille houses the large-diaphragm K 127 capsule. This capsule is derived from the K 103 (of the TLM 103), which accounts for its outstanding impulse response. The TLM 127 is thus capable of reproducing all transient phenomena of music and speech without any coloration. The sound character of the microphone is determined exclusively by the capsule; no electronic equalization is used.
