TLM 170R
This microphone gets its phenomenal, transparent sound and superior transient
VARIABLE PATTERN MICROPHONE
response through the application of the most modern electronic and mechanical
technology. The low self-noise and high SPL tolerance yield a dynamic range of
126dB. The transformerless TLM 170 has 5 precision remote-controllable
directional patterns, a 10dB pad, and a LF roll-off switch.
The TLM 170R is the first microphone to achieve remote
control of polar patterns via standard, two conductor
shielded microphone cable and 3-pin XLRtype connectors.
This superior, multi-purpose studio microphone
is ideal for use on large orchestras and small groups,
vocals, and individual instruments.
The TLM 170R comes with a tiltable, elastically
suspended bracket to isolate mechanical noise.
For remote control of the polar pattern, the “R”
position is selected and the N 48R-2 is required.
The N 48 R-2 will provide phantom power and
independent polar pattern control for two
microphones.
