HOW TO CONTROL FEEDBACK

A performer's number one enemy in using a microphone is -'feedback." This is a harsh hum, howl or squeal which occurs when the microphone picks up sound from the loudspeakers, re-amplifies and rebroadcasts it over and over again.

The key factors in feedback prevention are loudspeaker position in relation to the microphone, and working distance from the microphone. Feedback occurs if the microphone picks up sound from the loudspeakers. Keep the loudspeakers as far to the sides as possible-so they do not point toward the microphone. Always keep the microphone pointed toward and close to the performer and away from the loudspeakers. When stage monitor loudspeakers are used, make sure they are positioned in front of the performers and face the rear of the microphone.

In a room with hard walls, floor, and ceiling, loudspeaker sound may bounce back into the microphone and create feedback. Solve this ~ r o b l e mby turning down the amplifier volume control.

(Important Note: If you cannot solve the feedback problem with your close-talking microphone, a Shure Feedback Controller is suggested.)

BASIC POINTS FOR PROFESSIONAL MICROPHONE TECHNIQUE

Proper microphone technique will add to the overall effectiveness with which you project yourself to your audience. Keep the following points in mind when using this microphone:

1.Maintain the proper distance of l/z to 2% cm ('/4to 1 in.) from the microphone. This close working distance allows the microphone to cancel distant sounds and provide superior output under noisy conditions. This microphone has a strong proximity effect, that is, maximum bass output is obtained when it is used close-talking (see Figure 1 ) . For reduced bass response, hold the microphone a little farther away. For optimum noise rejection, do not work the microphone at distances greater than 5 cm ( 2 in.).

2.Don't needlessly change your distance from the micro-

phone as this will affect both the level and bass output.

3. Remember that this is a close-talking, voice-range microphone. It should not be used for musical instrument miking or general microphone use.

4.Consider the microphone as an instrument and practice your technique to enhance your performance.

YOUR SHURE MICROPHONE IS BUILT TO LAST!

Your Shure Microphone is ruggedly built and should give you years of uninterrupted service: however, remember that it is a sensitive electronic instrument. Avoid dropping the unit, or subjecting it to unnecessarily rough treatment. Normal usage, of course, will not impair performance of the unit. Use the protective carrying case to prevent damage not only when traveling, but also when storing the microphone.

WINDSCREEN

The external foam windscreen of your microphone should be cleaned occasionally. Slide it up and over the grille, rinse it in clean water, squeeze the water out, and allow it to dry completely before replacing. Be sure to replace with tapered

MICROPHONE CHECK-LIST
I .	Check microphone	impedance-is it correct for the am-
	plifier input being	used?

2. Check microphone cable connectors to microphone, mixer, and amplifier-are they tightly plugged in?

3.Check microphone, amplifier and/or mixer.

a.Are they turned on?

b.Are volume controls turned up?

IF THE MICROPHONE DOES NOT WORK

Check the above list. If the microphone still does not appear to be operating, check it on a spare cable. If microphone still does not appear to be operating, have the microphone and cable checked by your Shure Professional Entertainer Products Dealer, or write Service Department, Shure Brothers, Inc.
