Electrical features
The letters “TLM” stand for “transformerless microphone”.
In the TLM 67, an electronic circuit is used rather than a
conventional output transformer. Like a transformer, the
circuit ensures good common mode rejection, eff ectively
suppressing interference signals that aff ect the balanced
modulation line. The microphone can operate at sound
pressure levels of up to 105 dB without distortion, and has
a dynamic range of 94 dB (A-weighted), without the use of
the pre-attenuation switch.
Filter and pre-attenuation
The pre-attenuation switch on the back of the microphone
can be used to reduce transmission levels by approx. 10 dB.
It should be used only when there is a risk of overloading
following devices due to very high sound pressure levels.
Use of the switch does not increase the dynamic range of
the microphone, but rather shifts it by 10 dB, to higher
sound pressure levels. The other switch on the back of the
microphone can be used to change the cutoff frequency of
the built-in high-pass fi lter, so as to suppress the eff ects
of impact sound and wind noise, or to compensate for the
proximity eff ect.
Operational reliability
Elastic mounting of the capsule supplies protection from
the transmission of structure-borne noise. If required, the
EA 87 elastic suspension and WS 87 windscreen are availa-
ble as accessories, for further suppression of structure-bor-
ne and wind noise. The PS 15 or PS 20 a popscreen can be
used if the microphone is to be addressed at close range.
* These are just some of the most common applications. We recommend additional experimentation to gain maximum use from this microphone.
