uation pad prevents the micro-
phone's output level, particularly at
low frequencies, from overloading the
miniature transformers used in many
mixer input stages, etc.
•
Bass cut filter:
Selector 3 on the
microphone rear (refer to fig. 2 on
page 3) further reduces low-end dis-
tortion caused by footfall or wind
noise, etc. The filter also minimizes
the proximity effect that close-in mik-
ing from less than 4 inches causes in
any unidirectional microphone.The
filter rolls off at 12 dB/octave from
300 Hz downward.

3 Interfacing
3.1 General
The microphone uses a true
condenser transducer designed for 48-
volt phantom powering to DIN 45 596/
IEC 268-15. Neither the diaphragm nor
the backplate are permanently polarized,
so the microphone needs an external
power supply.
The microphone provides a balanced
output on a 3-pin male XLR connector:
Pin 1: ground
Pin 2: hot
Pin 3: return
