Product Code:
TLM103
|
The TLM 103* is the ideal large diaphragm microphone
for all professional and semi-professional applications requiring the utmost in
sound quality on a limited budget.
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.
Applications
Due to the universal cardioid pattern, straightforward handling, extremely low
self-noise level, and finally, the price, the TLM 103 is predestined for all
demanding applications from home recording to professional broadcasting and
commercial recording studios.
Polar pattern
The TLM 103 is equipped with a large diaphragm capsule with cardioid pattern. By
focusing on this pattern � used in most recording situations � the attenuation
of unwanted rear sound has been optimized. Off-axis sounds are rendered
naturally while isolation is increased. This also leads to a high feedback
suppression when the microphone is used in live situations or where loudspeaker
playback is a factor.
Acoustic features
The TLM 103 is addressed from the front, marked with the red Neumann logo on
the microphone body. The K 103 large diaphragm capsule is based on the K 87,
well known from the U 67 / U 87 microphones.The capsule has a flat frequency
response up to about 5 kHz, and above that, a wide flat 4 dB presence boost.
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.
Electrical features
With just 7 dB-A / 17.5 dB CCIR the self-noise level of the TLM 103 is so
reduced that even the smallest signals are reproduced basically noise-free. As
it is capable of handling sound pressure levels up to 138 dB without distortion,
the TLM 103 provides a dynamic range of 131 dB (A-weighted).
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.
Operational safety
The entire internal construction is elastically mounted to attenuate any
structure borne noise that could interfere with the TLM 103's operation.
Furthermore the capsule is set on an elastic mount. The frequency range reaches
below 20 Hz and thus even very low bass signals are reproduced without
coloration.
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. |
