Congratulations on the purchase of a new Shure PG Alta series microphone. The PG Alta series delivers professional quality audio at an affordable price, with solutions for capturing nearly any source, including voice, acoustic instruments, drums, and amplified electric instruments. Suitable for live and studio applications, PG Alta microphones are built to last, and meet the same rigorous quality testing standards that make all Shure products trustworthy and reliable.
The following table lists the most common applications and placement techniques. Keep in mind that microphone technique is largely a matter of personal taste; there is no one "correct" microphone position.
Application | Suggested Microphone Placement | Tone Quality |
---|---|---|
Guitar & Bass Amplifiers | 2.5 cm (1 in.) from speaker, on-axis with center of speaker cone. | Sharp attack; emphasized bass. |
2.5 cm (1 in.) from speaker, at edge of speaker cone. | Sharp attack; higher frequency sound. | |
60 to 90 cm (2 to 3 ft.) back from speaker, on-axis with speaker cone. | Softer attack; reduced bass. | |
Snare Drum | 2.5 to 7.5 cm (1 to 3 in.) above rim of top head of drum. Aim mic at drum head. | Most "snap" from drumstick. |
Before each use, make sure the grille is tightly secured on the microphone, as vibration and accidental hits with drumsticks may loosen it, resulting in signal loss.
Directional microphones progressively boost bass frequencies as the microphone is placed in closer proximity to the source. This phenomenon, known as proximity effect, can be used to create a warmer, more powerful sound.
Place the microphone so that unwanted sound sources, such as monitors and loudspeakers, are directly behind it. To minimize feedback and ensure optimum rejection of unwanted sound, always test microphone placement before a performance.
