TLM 103
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 cor-
rective resonance effects. Therefore, the microphone main-
tains an excellent impulse response and reproduces the
finest details of music and speech without coloration.
Electrical features
With just 7dB-A / 17.5dB CCIR the self-noise
level of the TLM103 is so reduced that even the
smallest signals
are reproduced
basically noise-
free. As it is ca-
pable of handling
sound pressure lev-
els up to 138dB
without distortion, the
TLM 103 provides a dy-
namic 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 en-
sures good common mode rejection, and
prevents RF interference that may influ-
ence the balanced audio signal.
Operational safety
The entire internal construction is elasti-
cally mounted to attenuate any structure
borne noise that could interfere
with the TLM103’s operation. Further-
more the capsule is set on an elastic
mount.
The frequency range reaches below
20 Hz and ths even very low bass sig-
nals are reproduced without coloration.
Due to this low frequency extension, the
TLM103 is more sensitive to structure
borne interference and wind noise. For such cases, the elas-
tic suspension EA1 and the windscreen WS 87 are availa-
ble as accessories. For close vocal use, the PS 15 or PS 20 a
pop screens are recommended.
The design of the microphone
is a registered design of
the Georg Neumann GmbH
in certain countries.
