Digital effects to problems and trouble

Digital effects: digital effects is processing, the manufacture of various sound field effects, reverb effect audio peripheral equipment, the following talk when using effects need to be aware of the problem and effects of potential failures: 1, in construction, to artistic and professional, many technicians like the effect is installed inside the Cabinet, this seemingly normal and reasonable, but due to the effect that the most vulnerable to outside interference, the Cabinet of equipment, plus a mixer from the Cabinet to the longer between signal lines, these are serious interference effects, causing effects to the sound mixer in the signal has a lot of noise, serious may all be noise can't use. So when the device is installed, it is best to put the effects on the side of the mixer, but don't and wireless devices such as microphones, drive stacked together. This is convenient, flexible transform what we need; then one of the most important thing is to reduce the interference. I believe there are many audio engineers are not aware of this, we can do the following experiment. 2, there are some effects when we select a good program, you also need to press the "lock" key, otherwise the program numbers have been flashing, indicating that this program has not been activated, then unless we know the original common program, do not blindly to lock another our unknown effects program, because some of the effects programs sound more "terrorist and weird", some programs of the signal output level is also very high, if you accidentally select a program, that may lead to MIC severe transfusion or serious deterioration of the human voice. 3, now most effects transform from one program to another program, the Center is to have a conversion time of the effects have no effect in the output, although only a few seconds, but if you show them transform effect or be aware of, we should try to avoid this phenomenon. 4. effects if action is not at that time, also produces acoustic feedback, this kind of feedback is sustained sound General, unlike the microphone acoustic feedback is short and strong, for example in a mixer, if we send a signal to AUX6 effects, after effects processing to output a 2-channel signal to a mixer of 23-24-channel, then at 23-24 in the two channels will stop AUX6 knob is turned on, otherwise just after effects processed signal will then flow back into the effects. Thus, AUX and effect between will also form a loop, when the loop level gain exceeds a certain range, it will result in acoustic feedback. Of course, a sound system that you want to have a good voice effects alone is not enough to handle, you also need to be issued in the system is very good and direct access to the sound, and then combined with the appropriate sound effects, it is only possible to achieve perfect vocal effects.
