Book_524137_1007_Sp6.book Seite 3 Freitag, 9. November 2007 2:22 14 MKH 800 TWIN The MKH 800 TWIN is a universal studio condenser microphone of exceptional quality. It includes a dual capsule consisting of two symmetrical push-pull transducers with high linearity. This is a “side fire” microphone with the two cardioid pick-up patterns of the transducer aligned back-to-back across the axis of the microphone. The MKH 800 TWIN is based on the MKH 800.

To attach the windshield: 왘 Slide on the windshield onto the sound inlet basket . To attach the popperstopper: 왘 Attach the gooseneck of the popperstopper to the stand. The popperstopper changes the sound only slightly.

Phase Super-cardioid** 왘 Set the amplification in the rear channel lower than in the front channel. 5 5 0 0 -5 -5 - 10 - 10 - 15 - 30 - 15 - 30 왘 Invert the phase of the rear channel.
Book_524137_1007_Sp6.book Seite 8 Freitag, 9. November 2007 2:22 14 Changing the pick-up pattern There are two different ways of changing the pick-up pattern of the microphone. If the microphone level has to be changed infrequently: 왘 At the mixing console, set the preamplification to the same value in both channels. 왘 Vary the pick-up pattern by using the level control and the phase switch of the rear channel. The level control of the front channel stays in the same position.
