Applications
Its capsule design and pickup pattern make the C 2000 B a perfect choice
for many applications both in the studio and on stage. Although the list
below is far from complete, it is a good starting point for making excellent
recordings. Please note that each instrument has its own distinct projection
pattern and the quality of the recorded sound ultimately depends on how
you place the microphone. You will therefore need to experiment to find the
optimum microphone placement for each instrument.

Powering
The C 2000 B operates on any phantom power source to DIN 45 596 /
IEC 268-15. This standard specifies a positive voltage of 12, 24, or 48 VDC
on the two audio lines referenced to the cable shield. Alternatively, you can
operate the microphone on any DC voltage between 9 and 52 V fed to the
microphone via standard phantom power wiring.

12 V ±2 V
24 V ±4 V
48 V ±4 V
In order to preserve symmetry, use 2 x Rv resistors with a maximum toler-
ance of 0.5% only.
If the amplifier inputs are single-ended (grounded) or have no input trans-
formers, wire either capacitors or optional transformers into the audio lines
to prevent any current leakage into the input stage.
