Congratulations on the purchase of a new Shure PG Alta series microphone. The PG Alta series

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.

General Rules for Use


Do not cover any part of the microphone grille with your hand, as this will adversely
affect microphone performance.

Aim the microphone toward the desired sound source (such as the talker, singer, or
instrument) and away from unwanted sources.

Place the microphone as close as practical to the desired sound source.

Work close to the microphone for extra bass response.

Use only one microphone to pick up a single sound source.

For better gain before feedback, use fewer microphones.

Keep the distance between microphones at least three times the distance from each
microphone to its source ("three to one rule").

Place microphones as far as possible from reflective surfaces.

Add a windscreen when using the microphone outdoors.

Avoid excessive handling to minimize pickup of mechanical noise and vibration.

Proximity Effect

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.

Avoiding Pickup of Unwanted Sound Sources

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.
