Shure PGA27 Manuel D’Utilisation

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.

Connecting to a Mixer or Computer

Use only balanced (three-conductor) cables. Otherwise, 

the cable will not carry phantom power to the microphone. 

If using an adapter for 6.5mm (1/4") inputs, it must have 

tip-ring-sleeve (TRS) contacts.

To deliver audio directly to a computer, use a USB audio 

interface with an XLR microphone input that provides 

+48V phantom power, such as the Shure MVi.
