User manual AKG CK 92

[. . . ] B 18 battery power supply for all Installation Modules except GN 30 OC. Note that both the maximum working distance and the area covered by the microphone depend on the pickup angle. The smaller the pickup angle (hypercardioid), the longer the maximum distance between the talker and the microphone and the smaller the area covered by the microphone. Whether an omnidirectional, cardioid, or hypercardioid capsule will give the best results therefore depends on the specific application situation (see Table 1). [. . . ] To lock the capsule, use commercial minimum-tack screw locking adhesive that allows you to unscrew the capsule later if need be. â· Before replacing a Capsule Module, be sure to switch your sound system OFF in order to prevent unwanted noise. Prior to using the GN 15/30/50 ESP, you may choose to program the functions of the ON/OFF key, LED ring, and bass cut filter as detailed in Tables 2/2a on pages 28/29. Touch a bare, grounded metal part to discharge any static charge that may have built up on your body. Position 1 7 Jumper in place Flat frequency response Mic on/off -> LED on/off No jumper Bass rolloff: -6 dB below 200 Hz LED off Positions 2 through 6 set the following functions: ON/OFF Key Functions Table 2a: ON/OFF Key Positions, 2, 3, 4: Be sure to place a jumper at one (but no more than one) of these three positions. If you place no jumper at any of these positions, pushing the ON/OFF button will have no effect. Positions 5, 6: Make sure there is a jumper placed at one of these positions at all times. With jumpers at both or none of these positions, the microphone status on power-up will be undefined. Never place two jumpers at positions 6 and 2 or 5 and 4 at the same time. Do not use any jumper configurations other than those given in Table 2a. To make the circuit board slide more easily into the shell, turn the circuit board two or three times completely about its longitudinal axis as you push the circuit board in. If the phantom power on your mixing console is switchable, switch the phantom power on. You may also connect the GN 15, GN 30, and GN 50 installation modules to a PT 40, PT 400, or PT 4000 bodypack transmitter from AKG. The LED rings on the GN 30/50 Minijack Installation Modules will be powered from the phantom supply. ) To obtain an open channel indication, the installation technician may connect the LED ring to an external power source. In this mode, the LED ring will light much more brightly to draw the required attention to the open microphone. Unsolder the black wire (LED +) and the outer shield (LED -) from the HSC mounting flange and insulate the bare ends of the two wires. Solder to the two contacts on the HSC that are now unused a two-conductor cable for powering the LED ring. Use the supplied pipe clip to fix the phantom power adapter to the underside of the table. Use a shielded cable to connect the DPA phantom power adapter to a microphone input with phantom power. If the phantom power on your mixing console is switchable, switch the phantom power on. Insert the jack plug on the gooseneck into the mini jack on the mounting flange and screw the gooseneck down. [. . . ] Pass the cable through the hook or over the line so that it will hang at the desired height. â· Do not tie a knot into the cable to hang it on the hook. Hold the cable with one hand and turn the microphone carefully into the desired position. Stretch a suitable length of fishing line horizontally across the room, passing the fishing line through the eye on the HM 1000. [. . . ]
