1、MODEL PESOSP Slips out of swivel stand adapter easily and quickly for hand-held use Your selection of a Shure SUPER-PRO Cardioid Microphone will contribute significantly to the professional quality of your performance. This ball-type microphone has a super rugged steel mesh screen with a special fil

2、ter which pro- vides protection from wind, blast and pop (explosive breath sounds). This feature allows you to work as close to the microphone as you wish, to reduce the pickup of unwanted sounds either indoors or out-of-doors. Your microphone helps control feedback because it is uni- directional. S

3、ince it picks up sound only from the front of the microphone, audience noise and other unwanted sounds occurring at the rear or sides of the microphone are sup- pressed. This permits a greater working distance from the microphone with minimal background sound pickup. The PESOSP also features instant

4、 usage with low- or high- impedance microphone inputs using the line matching transformer supplied. (See inside for information on how to use your Shure Microphone more effectively.) RadioFans.CN 收音机爱 好者资料库 HOW TO CONTROL FEEDBACK A performers number one enemy in using a microphone is feedback. This

5、 is a harsh hum, howl or squeal which oc- curs when the microphone picks up sound from the loudspeakers, re-amplifies and rebroadcasts it over and over again. The key factor in the prevention of feedback is the posi- tion of the loudspeakers in relation to the microphone. Feedback occurs if the micr

6、ophone picks up sound coming from the loudspeakers. Keep the loudspeakers as far to the sides as possible-so they do not point toward the micro- phone. Always keep the microphone pointed toward the performer and away from the loudspeakers. When stage monitor loudspeakers are used, make sure they are

7、 posi- tioned in front of the performers and face the rear of the microphone. If you are in a room with hard walls, floor, and ceiling, the sopnd from the loudspeakers may bounce back into the microphone and create feedback. Solve this problem by turning down the amplifier volume control and working

8、 closer to the microphone. (Important Note: If you cannot solve the feedback prob- lem with your SUPER-PROTM microphone, a Shure Feed- back Controller is suggested.) BASIC POINTS FOR PROFESSIONAL MICROPHONE TECHNIQUE Proper microphone technique will add to the overall ef- fectiveness with which you

9、project yourself to your audience. Keep the following points in mind when using the microphone: 1. Maintain the proper distance from the microphone. When you wish to achieve an intimate tonal quality, get closer to the microphone and lower your voice. For wide-open driving effects, raise your voice

10、and back away from the microphone so that you do not over- drive your amplifier to distortion. 2. Dont change your distance from the microphone needlessly, as this will affect the level of sound coming from the loudspeakers. 3. Consider the microphone as an instrument and prac- tice your technique t

Your Shure Microphone is ruggedly built and should give you years of uninterrupted service; however, remember that it is a sensitive instrument. Avoid dropping the micro- phone, or subjecting it to unnecessar

12、ily rough treatment. Normal usage, of course, will not impair performance of the unit. Use the protective carrying case to prevent dam- age not only when traveling, but also when storing the microphone. MICROPHONE CHECK-LIST 1. Check microphone impedance-is it correct for the amplifier input being u

13、sed? 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 appea

14、r to be operating, check it on a spare cable. If the 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.

15、es and/or their cables for proper phasing, connect them to an amplifier and talk or sing into them while holding them three or four inches apart. The sound from the speakers should be the same when talking into either microphone or directly between them if they are in phase with each other. If the s

16、ound drops drastically, or if a dead spot is found when talking between the two microphones, one of them or its cable (low impedance only) is out of phase. All cables and microphones should be tested in this manner to insure that they are in phase with each other. To change the phase of a low-impeda

17、nce microphone cable, either use a Shure AlSPR Phase Reverser or inter- change the wires connected to pins 2 and 3 of the connec- tor. To change the phase of a microphone, the microphone cartridge leads must be interchanged (see Figure 2). This should be performed by your dealer, the Shure Factory S

18、ervice Department, or other qualified service personnel. IMPEDANCE Your microphone is supplied wired for low impedance for connection to low-impedance microphone inputs (rated at 19 to 300 ohms). For instant change for connection to high-impedance (?4 in. phone jack) microphone inputs, connect the s

19、upplied cable (or any number of additional CS 1 CNs) to the low-impedance side of the furnished A95FP Line Matching Transformer and plug the high- impedance side (% in. phone plug) into the input. For internal impedance change, remove male plug insert by turning slotted setscrew inward (counterclock

20、wise). Disconnect two-terminal impedance selection socket from rear of male insert, and reconnect socket in reverse posi- tion so that pin 3 of male insert is inserted in socket terminal H. NOTE: After following the above direc- tions, the PESOSP with the supplied two-conductor CSlCN cable will be s

In this case, the following points should be remembered: 1. It is best if the microphones are individually controlled for volume throug

23、h a separate Shure microphone mixer. If this is not possible, it is desirable that each performer use the same type and model of microphone so that the group as a whole will be balanced. 2. Check the placement of the microphones with relation to loudspeakers (as previously mentioned) so that feedbac

24、k is minimized. 3. As additional microphones are added the possibility of feedback increases. Turn off, or down, unused micro- phones to help solve this problem.
