Neumann TLM 103 D

Digital version of the popular TLM 103, pure Neumann sound in the digital domain, for use with AES/EBU, AES 42 or S/PDIF. The signal is converted directly at the capsule.

Neumann has repeatedly set new standards in the field of analog microphone technology. The first condenser microphone, switchable directional characteristics, the first stereo microphone and 48 V phantom power were all developed by Neumann, introducing new dimensions to the field of microphone and recording technology.

With the digital Solution-D microphone system, Neumann has now succeeded in bringing the dynamic range and signal fidelity of the best analog studio microphones into the digital realm. This means that, for the first time, the whole audio production signal chain is entirely digital.

Optimal A/D conversion, especially developed synchronization technology and the capability of controlling standard microphone parameters and various integrated signal processing functions remotely ensure that Solution-D meets the most demanding professional audio production requirements. The basic technological principle is to permit recording with no "bottlenecks" associated with loss of signal quality.

The comprehensive features provided by Solution-D make it possible to achieve excellent quality with small digital productions - with only a single microphone and a recording device.

About the Neumann TLM 103 D
In the microphone, the Neumann A/D converter which has been extensively proven in the D-01 receives the output signal directly from the capsule. With a dynamic range exceeding that of the capsule, the converter permits optimal utilization of the capsule qualities. This ensures that the capsule signal is made available to the recording system without any coloration, with a hitherto unknown transparency.

If required, the DSP functions integrated into the microphone can be configured and controlled remotely via the DMI-2 digital microphone interface and the RCS remote control software. These functions include gain setting, a compressor/limter with an additional de-esser function, and a peak limiter. The digital concept proves particularly beneficial here. The peak limiter, which receives the output signal almost directly from the capsule, acts as an automatic "safety valve", permitting safe exploitation of the entire available dynamic range even in stressful recording situations.

For the purpose of clear identification, information concerning the name of the manufacturer, model, serial number and installed software version is transmitted by the microphones to the connected receiver.

The microphones are equipped with a 3-pin XLR connector for transmission of a bi-directional signal conforming to the AES 42 standard. This signal includes the balanced digital microphone output signal, the phantom power supply, and a remote control data stream that also contains a signal for synchronizing the microphone with a master clock.

Two versions of the TLM 103 D are available: Classic nickel, and black finish. All standard sampling frequencies are supported, from 44.1 kHz to 192 kHz.
  • Large diaphragm cardioid microphone
  • Pressure gradient transducer with with one-diaphragm capsule
  • Includes swivel mount
  • The legendary Neumann sound in the digital realm.
  • Pure Neumann capsule sound.
  • The satisfaction of recording the uncolored original, with no "bottlenecks" between the capsule and the recording system.
  • The guarantee of having one of the best
  • A/D converters available.
  • Anti-clipping processing ensures handling safety, and reduces stress.
  • Reduced time requirements and personnel costs, particularly due to faster post production processing.
  • Lower investment costs, since separate A/D converters and preamps are no longer needed. This also means space and weight savings (e.g. in the OB van).
