USER GUIDE

PGA181

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

Cables

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.

Computer

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.

Mixer

When connecting to a mixer, use only balanced, microphone-level inputs with phantom power. Most mixers have a switch

for phantom power, so make sure phantom power is on for that channel.

Phantom Power

All condenser microphones require phantom power to operate. This microphone performs best with a 48 V DC supply (IEC-

61938), but it can operate with lower voltages.

Phantom power is provided by the mixer or audio interface that the microphone is connected to, and requires the use of a

balanced microphone cable: XLR-to-XLR or XLR-to-TRS. In most cases, there is a switch or button to activate the phantom

power. See the user guide for the mixer or interface for additional information.

Positioning the Microphone

The front of the microphone is marked by several indicators:

four screws around the grille, the cardioid logo, and the

PGA181 model number. Position this side toward the sound

source.

Applications

The following table provides a basic starting point for several instruments. Shure offers additional educational publications on

microphone placement and recording techniques. Visit www.shure.com for more information.

Application Distance from source Tips

Voice 1-3 inches (2-8 cm) Use a pop filter (Shure PS-6) to prevent

plosives.

Acoustic guitar 6-12 inches (15-30 cm) Place near the sound hole for a full sound,

or near the 12th fret for a balanced, natural

sound.

Drums 3-6 feet (1-2 m) Place in front of the drum kit to capture more

of the kick drum, or as an overhead (above

the kit, facing down) to capture more cymbals.

Consider using additional Shure microphones

placed on individual drums for more mixing

flexibility and a thicker sound.

Amplifiers 1-6 inches (2-15 cm) Aim towards the center of the speaker for a

clear, aggressive sound, or towards the edge

of the speaker for a mellow sound.

Strings or horns 1-6 feet (30 cm - 2 m) For a single instrument, place the microphone

close to the source. For a horn or string

section, arrange players at an equal distance

from the microphone.

Full band 3-10 feet (1-3 m) Face the microphone towards the group,

centered between instruments.

Tip: Close microphone placement results in a full sound due to the proximity effect. Placing the microphone farther from the

source results in more room ambience.
