The pattern control knob on the CTM-1500VP has a center
detented cardioid position. This allows the user to quickly
and consistently lock the mic in a cardioid pattern. By turn-
ing the knob clockwise from the center, the pattern varies
continuously from cardioid, to subcardioid, through omni-
directional. By turning the knob counterclockwise from the
center, the pattern varies continuously from cardioid, to
hypercardioid through bidirectional (Fig.8). This allows the
user to adjust to the optimal pattern needed for almost any
recording or live situation.
Getting Started
The high gain and wide bandwidth of the CTM-1500VP microphone will easily overload
the inputs of many professional mixing consoles if adequate precautions are not taken.
This is especially true if the microphone is going to be used on percussion or amplified
electronic instruments. If you have never used this microphone before, we strongly
recommend that you initially reduce the system gain by doing one or more of the following:
• Enable the pad switch on the input of your mixing console.
• Start with the input trim control on your mixing console turned down to a low level.
• Enable the -20 dB pad switch on the CTM-1500VP microphone.
• The CTM-1500VP requires a 24-52V phantom power supply, delivering at
least 8mA for proper operation.
* Due to our continuous efforts to improve our products and promote the development
of standards, specifications are subject to change without notice.
