Operation

 

The CM49 is equipped with a 8-pin Tuchel connector that plugs into 
the base of the microphone and screws tight. Always make sure that 
the PSU is switched off when plugging the microphone connector 
into the microphone and PSU.

How to change the polar pattern.

Locate the white pattern switch on the PSU. Use this switch to 
change the directional characteristics: omni-, cardioid-, figure-eight, 
and eight intermediate positions. The center position with the 
Wunder Audio logo is the cardioid setting. 

As you turn from position to position it will take a few seconds for the  
polarization voltage to settle and achieve the desired polar pattern. 

How to mount the microphone

A special Yoke mount/stand adapter is provided and should always 
be used to mount the microphone on floor stands or booms. 

To mount the microphone, fully unscrew the knurled knob on the 
side of the metal belt. Place the microphone into the metal belt 
making sure that the red jewel on the front of the microphone is 
centered into the center hole on the yoke belt. Make sure that the 
there is no black rubber grommet in the center hole on the belt, if it 
is present, remove it.

Close the metal belt carefully around the microphone making sure 
that the leading edge of the metal belt does not scratch the body of 
the microphone. Screw the knurled knob clockwise to tighten the 
belt around the microphone.

The CM49 can now be placed with the microphone on stands or 
booms with standard thread sizes. It may also be swiveled against 
the stand axis to suit the recording angle.
