User manual AKG C 12 VR

[. . . ] Drops from even moderate heights may cause the filament to break and would result in immediate failure of the microphone. It would be advisable for the users to keep a spare tube ­ specially selected by an AKG Service Departement ­ always ready for replacement. Turn the three grub screws at the lower end of the microphone into the body in clockwise direction until the outer housing can be pulled off in downwards direction. [. . . ] The clamp of the shockmount should be guided from the lower end of the microphone upwards until it is placed near the gravitational centre (slightly below the engraving). The shockmount can now be placed with the microphone on stands or booms with thread sizes of 3/8 or 5/8 inch. It may also be swivelled against the stand axis to suit the recording angle. powering of the microphone: The required power unit N 12 VR is included in the delivery. It is clearly marked and quite obvious by connector type and size, how to connect the microphone to the power unit with the 10 m (30 ft. The audio frequency may be taken from the power unit transformer balanced by a conventional audio cable with standard XLR-type connector. Prior to connecting the N 12 VR to AC power, check the AC voltage of the power line you are going to connect the N 12 VR to. Check that the N 12 VR AC voitage selector to the right of the power switch on the front panel is set to the same AC voltage. If it is not, use a flat-blade screwdriver to set the AC voltage selector to the correct voltage. Warning: Connecting the N 12 VR to the wrong AC voltage may destroy the unit and cause fire and/or electric shock. The fuse protecting the primary circuit is located in the marked fuse compartment below the power connector. use a flat-blade screwdriver to open the fuse compartment lid. Replace the fuse with a new fuse of the same type (T 100 mA) and close the fuse compartment lid. the 50-mA , fast-blow fuse protecting the anode circuit is located on the circuit board inside the unit. Disconnect the unit from AC power by unplugging the power cable. Replace the fuse with a new 50-mA, fast-blow fuse.

The book is published by "Arsis Baedeker und Land Verlags GmbH" and available at your local music shop. Both studio and "onstage" applications are discussed in detail. [. . . ]
