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. Difficult questions concerning the optimal preamp and A/D converter for a Neumann mic are thus a thing of the past.
For many years the analog version of the TLM 103 D has played an important role for ambitious home recording and project studios. This microphone has made the Neumann sound available to a broad spectrum of demanding audio engineers and musicians. The TLM 103 D provides all of the sound features of its analog counterpart, in addition to the advantages of digital circuit technology described above.
TLM 103 Microphone
By utilizing the tried and true transformerless circuit found in numerous Neumann microphones, the TLM 103 features yet unattained low self-noise and the highest sound pressure level transmission. The capsule, derived from that used in the U 87, has a cardioid pattern, is acoustically well-balanced and provides extraordinary attenuation of signals from the rear.
The TLM 103 is available in satin nickel and matte black. Delivery includes an SG 1 metal swivel mount and a wooden jeweler's box.
The large wire mesh headgrille protects the capsule from plosive sounds and effectively prevents pop noises. These characteristics are achieved without resorting to corrective resonance effects.
Therefore, the microphone maintains an excellent impulse response and reproduces the finest details of music and speech without coloration.
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.
Due to this low frequency extension, the TLM 103 is more sensitive to structure borne interference and wind noise. For such cases, the elastic suspension EA 1 and the windscreen WS 87 are available as accessories. For close vocal use, the PS 15 or PS 20 a pop screens are recommended.
- 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).
