PG Alta™ Studio Starter Kit

PG Alta Microphones

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. 

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.

Microphone Techniques for Stereo 

Recording

Stereo recording using two microphones adds realism by 

capturing sound similar to the way that humans hear. Panning 

(directing the signals left and right) adds width and directionality 

when listening on stereo systems or headphones.
Tip: Panning the signals farther apart increases stereo separation 

and width. Be careful of panning too far, as it may result in a 

hollow sound in the middle of the stereo field.

① X-Y Coincident Pair

The X-Y technique 

provides excellent phase 

coherency because sound 

arrives simultaneously at 

both microphones. 
Placement: Set up the 

microphones with the 

capsules close together, 

but not touching. 

Experiment with angles 

between 90 and 120 

degrees to capture the full 

width of the source.

② ORTF 

Developed as a French 

broadcasting standard, 

ORTF technique 

replicates the spacing 

and angle of human 

ears. It provides a 

natural, wide sound.
Placement: Angle the 

microphones at 110°, 

with the capsules 17 cm 

apart.

③ A/B Spaced Pair

Spaced pair recording 

can deliver a dramatic 

stereo effect because 

sound arrives at each 

microphone at a slightly 

different time, providing 

the listener with timing 

cues that localize 

sounds. 

1-3 m

(3-10 ft)

Note: 
For drum overheads, the snare drum should be equidistant 

from each microphone to achieve a tight, focused sound. Use 

a measuring tape or piece of string to verify this distance.
