Continuously variable pattern control allows the operator to "dial in" precise coverage according to desired miking techniques as well "dial down" feedback potential according to mic placement and reflected sound waves. Vintage capsule voicing features a slight rising audio response at 6KHz and 12KHz (cardioid) makes the CTM-1500VP the choice for vocal, choral and acoustic instruments in fidelity sound reinforcement as well as recording and broadcast applications. Features • Ideal for miking choirs, vocals and acoustic instruments • Continuously variable polar pattern selector • Hi pass filter (6dB/oct @ 100Hz) • 20dB pad • Premium 1.1" diaphragm • Transformerless output for high SPL and high sensitivity • Operational amplifiers instead of Field Effect Transistors assure optimum performance and very high gain • New discrete high efficiency power supply circuit allows greater dynamic range and lower self-noise • Included stand adapter, shockmount and vinyl pouch The implementation of high speed, low noise, low distortion electronics combined with a vintage capsule design and continuously variable pattern control make the CTM-1500VP a new benchmark of flexibility when selecting a large diaphragm condenser mic for performance sound reinforcement. ASTATIC Quality All CTM-1500VP microphones are audio tested and inspected prior to shipment. Our absolute commitment to quality insures that ASTATIC microphones remain the Best Value in today's competitive industry. cardioid fig. 8 omni cardioid fig. 8 omni 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 turning the knob clockwise from the center, the pattern varies continuously from cardioid, to subcardioid, through omnidirectional. 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.
