[. . . ] Please make sure that the piece of equipment your microphone will be connected to fulfills the safety regulations in force in your country and is fitted with a ground lead. Built-in windscreen/pop filter for effective suppression of pop and breath noise. Stubs for floor stands allow you to place the microphone at the optimum position in front of the bass drum or a bass amp. [. . . ] This may cause hum or similar noise when you use a cable that is longer than 16 feet (5 m). Plug the female XLR connector on the microphone cable into the male XLR connector on the microphone. Plug the other connector on the microphone cable into the desired microphone input jack on your mixer or amplifier. The best way to get the "right" sound is to experiment with microphone placement. Please note that moving the microphone closer to the instrument will boost the bass range. In order to capture the entire frequency spectrum of the trombone, direct the microphone toward the lower rim of the bell. On stage, you may have to move as close as 2 inches to the microphone in order to avoid getting feedback or spillover from other instruments. In order to optimally capture all the frequencies emitted by the tuba, aim the microphone at the perimeter of the bell from above. On stage, you may have to move the microphone closer to the instrument (as close as 2 inches) in order to prevent feedback or spillover from other instruments. In this situation, take extra care not to blow right into the microphone. If you get too much blowing noise, use an additional external windscreen, e. Place the microphone about 2 to 6 inches in front of the loudspeaker diaphragm and aim the microphone at the center of the diaphragm. The microphone will capture the entire frequency range and thus the pristine combined sound of the instrument and amplifier. You may mount the microphone on the boom of a floor stand and align it as described above. If you prefer a less visible alternative, we recommend to mount the microphone on the optional ST 305 floor stand or a table stand from AKG: 1. Screw at least one or, if necessary, both of the two supplied StA 550 extension stubs on the stand.
