The pattern control knob on the CTM-1500VPhas 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-1500VPmicrophone 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-1500VPmicrophone.

•The CTM-1500VPrequires a 24-52V phantom power supply, delivering at least 8mA for proper operation.
