User manual CAD AUDIO VX2

[. . . ] This new capsule is extremely large with an actual diaphragm diameter of 1 1/4". The high tension diaphragms are aged, gold sputtered, and made from the newest 3 micron thick high strength polymer film. The other capsule components are precision machined brass and stainless steel. Each capsule is hand dampened and assembled in a state of the art clean room facility. [. . . ] Never open the microphone housing when it is connected to the power supply. The power supply should only be opened by a qualified service technician. Tube Replacement Flat Response Pad Off (0 dB) Omnidirectional Cardioid Figure 8 The tubes that are used in the VX2 have been hand selected for low noise, and burned in to provide years of service. A 12AX7 (V1) is used for the head-amp and a 12AU7 (V2) for the output section. The actual number that appears on the tubes in your microphone may be different. These tubes are a very popular type that are used in many guitar amplifiers and music equipment. However, to insure continued operation within factory specs, it is recommended that you purchase replacement tubes from CAD. To gain access to the tubes, first disconnect the microphone from its power supply. Remove the microphone from the shock mount by unscrewing the two knurled knobs on either side of the microphone head. Then unscrew the single knurled knob on the back of the mic near the XLR connector. To make it easier to remove the housing, place the small toggle switches in the high-pass, and -8 dB pad position. Remove the switch bezel by removing the screws on the sides of the bezel. Remove the mic housing by unscrewing the two screws on the end of the mic near the XLR connector. Carefully slide the housing off, making sure the housing clears the small toggle switches. The tube positions are marked on the printed circuit board near each tube socket. Replace the body by sliding it over the chassis, being careful to clear the small toggle switches. Note: If the screws in the switch bezel do not align properly, the body may not be fully seated. Loosen the screws on the body and realign it first. ZM-2 Shock Mount The ZM-2 shock mount is an integral part of the VX2 microphone and only needs to be removed to service the microphone or to exchange the capsule/screen assembly with a different type. To remove the shock mount, unscrew the two knurled knobs on either side of the microphone head first, then unscrew the knurled knob in the back of the microphone. To replace the shock mount, install the knurled knob in the back of the microphone FIRST. Then install the knurled knobs on the sides of the microphone head. Power Supply The VX2PS power supply is set for 117VAC operation at the factory. For 220VAC operation, change the switch on the rear panel of the supply to 220V.
