How to mount the microphone
A special shock mount/stand adapter is provided and should always 
be used to mount the microphone on floor stands or booms. The 
clamp of the shock-mount should be guided from the lower end of 
the microphone upwards until it is placed near the gravitational 
centre (slightly below the badge or centered over the badge). The 
shock-mount 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.
Powering of the microphone:
The required PSU is included in the delivery. It is clearly marked and 
quite obvious by connector type and size, how to connect the 
microphone to the power unit with the supplied CM67 microphone 
cable. The audio frequency may be taken from the power unit 
transformer balanced by a conventional audio cable with standard 
XLR-type connector.
2. The CM67 Power Supply
This PSU supplies the microphone with the –6.3 volt filament and 
210V plate voltage for the vacuum tube.
The CM67 PSU has internal AC voltage sensing and the user 
does not need to change any internal settings on the PSU to 
use with different AC voltages worldwide
Power Connector
Especially on tour, you may need to connect the unit to a power 
outlet that does not match the power connector on the supplied 
power cable. Purchase a matching power cable locally that complies 
with IEC and local safety standards and has a power connector with 
a chassis ground pin. While in the same area, use this “local“ power 
cable only.
