1、MODELS 588SA AND 588SB UNIDIRECTIONAL DYNAMIC MICROPHONES GENERAL The UNlSPHERE B Models 588SA and 588SB are unidirectional dynamic microphones with a very effec- tive filter for excellent protection from breath popping and wind noise. The microphones are available either as high impedance (588SA) o

2、r low impedance (58888); they provide natural, lifelike reproduction of vocal and in- strumental music; they are ideal for sound reinforce- ment and tape recording. These microphones are particularly suitable when unidirectional sound pickup is required because of feedback problems. Because they are

3、 unidirectional and pick up sound from the front while suppressing sound from the rear, the 588 Series can be used closer than usual to loudspeakers without the annoying squeal caused by feedback. They also permit higher amplifier gain before feedback. They are very ap- propriate in locations such a

14、OVERALL DIMENSIONS FIGURE 3 Net Weight (less cable) 340 grams (12 oz) PHASING To test two microphones andlor their cables for pro- per 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 t

15、alking into either microphone or directly between them if they are in phase with each other. If the sound drops drastically, or if a dead spot is found when talking between the two microphones, either the microphones or their cables (low impedance only) are out of phase. All cables and microphones s

16、hould be tested in this manner to insure that they are in phase with each other. To change the phase of a low-impedance microphone cable, either use a Shure A15PRS Phase Reverser or in- terchange the wires connected to pins 2 and 3 of the connector. To change the phase of a microphone, the microphon

17、e cartridge leads must be interchanged (see Figure 4). This should be performed by your dealer, the Shure Factory Service Department, or other qualified service personnel.
