[. . . ] Negative acoustic effects caused by the housing and the sound inlet basket are minimised. The small, slim design and the optionally dark housing design (Nextel) make it visually unobtrusive. 3 Delivery includes 1 MKH 800 TWIN studio condenser microphone 1 MZS 80 shock mount 1 AC 20 adaptor cable (1 x XLR-5 socket to 2 x XLR-3 connector) 1 MZQ 80 microphone clamp 1 Aluminium transport case 2 supplementary sheets with the front and rear frequency response curves Instructions for use: ­ MKH 800 TWIN ­ MZS 80 shock mount ³ » · ¿ ´ ³ Sound inlet basket · LED Front (blue) » LED Rear (red) ¿ XLR-5 connector of the microphone ´ AC 20 adaptor cable 4 Putting the microphone into operation Connecting the microphone The MKH 800 TWIN has been designed for a 48 ± 4 V phantom powering according to IEC 61938. To power the microphone: Connect the XLR-5 socket of the adaptor cable ´ to the XLR-5 connector ¿ of the microphone. Connect the two XLR-3 connectors of the adaptor cable ´ to the corresponding sockets of your mixing console. Switch on the phantom powering on your mixing console. The LEDs · and » on the microphone light up. Aligning the microphone The front of the microphone is marked by the word "Front" and a blue LED · whereas the rear is marked by a red LED ». The LEDs can be used for aligning the microphone. On-axis alignment is indicated by maximum brightness. Function monitoring The two LEDs Front · and Rear » indicate operational readiness separately for both channels. The LEDs go off if the supply voltage drops below 42 V. Mounting the microphone to a stand The supplied MZS 80 shock mount allows the MKH 800 TWIN to be mounted to a stand and effectively protects against structure-borne noise. To mount the microphone to a stand: Select the suitable mounting thread: ­ Without thread insert: 5/8" thread ­ With thread insert: 3/8" thread Screw the shock mount ² to a stand. Pass the cable through the cable grip as shown. Place the microphone into the shock mount ² as shown. ² 5 Attaching the windshield Pop noises resulting from close miking can be suppressed effectively using the optional MZW 80-ANT windshield or the optional MZP 40 popperstopper (see "Accessories and spare parts" on page 9). To attach the windshield: Slide on the windshield onto the sound inlet basket ³. To attach the popperstopper: Attach the gooseneck of the popperstopper to the stand. The popperstopper changes the sound only slightly. Remote adjustment of the pick-up patterns The two signals of the MKH 800 TWIN allow the remote adjustment of the pick-up patterns at the mixing console. The two microphone signals (front and rear) are routed to separate channels and summed together. The sum signal is then distributed over the stereo channels as usual using the pan control. The pan control of both channels has to be aligned identically for correct operation. Pick-up pattern Omni-directional Setting Set the amplification to the same value in both channels. 5 0 -5 5 0 -5 Wide cardioid* Set the amplification in the rear channel lower than in the front channel. 5 0 -5 - 10 - 15 - 30 5 0 -5 - 10 - 15 - 30 Cardioid Activate the front channel only. 5 0 -5 - 10 - 15 - 30 - 40 5 0 -5 - 10 - 15 - 30 - 40 - 6 Pick-up pattern Figure-8 Setting Set the amplification to the same value in both channels. 5 0 -5 5 0 -5 Invert the phase of the rear channel. Phase Super-cardioid** Set the amplification in the rear channel lower than in the front channel. 5 0 -5 - 10 - 15 - 30 5 0 -5 - 10 - 15 - 30 Invert the phase of the rear channel. Phase *Wide cardioid: Pattern between omni-directional and cardioid The wide cardioid pattern of the MKH 800 is, for example, the result if the rear channel has 10 dB less amplification than the front channel. The pick-up pattern becomes more omni-directional at higher amplification and more cardioid at lower amplification. At the same time, the rear attenuation (180° attenuation) of the microphone changes. It is the direct result of the amplification ratio between the front and the rear channel, i. e. [. . . ] If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 1. Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. [. . . ]
