Using The Microphone; Introduction; Bass Cut Filters - AKG Acoustics C 414 LTD Mode D'emploi

When adding phantom power to a grounded or transformerless
input, be sure to insert either capacitors or a transformer into the
audio line to prevent current leakage into the input circuitry.
Besides offering high headroom, minimum distortion, as well as
temperature and humidity resistant construction, the microphone
is suited for a uniquely wide range of applications.
The C 414 LTD LImited Edition features a very smooth frequency
response and the typical sound of AKG large-diaphragm micro-
phones. This sound has hardly changed over the many years the
C 414 has been in production, and the C 414 has become an "in-
dustry standard" against which most competitive or new prod-
ucts are compared.
You can use the C 414 LTD for most musical instruments (see
also section 3.5). Selector 1 lets you optimally adjust the micro-
phone's polar pattern to the instrument to be recorded and the
recording environment.
The selectable bass cut filters at 40 Hz and 80 Hz will effectively
cancel out any unwanted noise such as blower noise from air
conditioning systems, etc., or low-frequency noise due to floor vi-
brations, handling noise, etc. without affecting the sound of the
recorded voice or instrument on tape.
