belt around the microphone.
The CM50 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 with the microphone. It is clearly
marked and should be quite obvious by connector type and size
how to connect the microphone to the power unit with the supplied
CM50 microphone cable. The audio signal may be taken from the
transformer-balanced power unit by a conventional audio cable with
standard XLR-type connector.
After connection of the microphone, the power supply, and AC line,
the main switch may be switched on. Operating condition will be
indicated by the power lamp.
The warm-up time of the CM50 is approximately one minute. When
your CM50 is new, a 24-hour burn-in period is recommended.
The CM50’s tube will “break in” over a period of time enabling the
mic to sound subtly better over a period of time.
2. The CM50 Power Supply
This PSU supplies the microphone with the 4V filament voltage and
115V plate voltage for the vacuum tube.
Prior to connecting the CM50 to AC power, check the AC voltage of
the power line you are going to connect to the CM50.
The CM50 PSU has an internal AC voltage selector switch.
To check the CM50 PAU AC voltage selector switch, first unplug the
AC cable (power plug) from the PSU.
