USING MORE THAN ONE MICROPHONE It is often desirable for a group to use a separate microphone for each individual performer. In this case, the following points should be remembered: 1 . It is best if the microphones are individually controlled for volume through a separate microphone mixer such as the Shure PE68M Mixer. I f 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 feedback is minimized. 3. As additional microphones are added the possibility of feedback increases. Turn off, or down, unused microphones to help solve this problem. MODEL PE610 FEEDBACK CONTROLLER Lets you "tune" your sound system to the acoustics of the room. The result is more overall sound power without feedback. Eight linear-motion filter controls are infinitely variable from 0 to 12 dB cut. Below 63 Hz and Above 8 kHz roll-off switches attenuate low and high frequencies. Can be installed between mixer or console and amplifier for total system control, or following each microphone as a single-channel preamplifier with feedback control.
