压限器介绍（Introduction of pressure limiter） Pressure limiter introduces.Txt49 rocks because of conviction, it aroused the beautiful waves; youth because of the pursuit of lofty, only exceptionally bright and colorful. 50 because young, so self-confidence; because of self-confidence, so young. The singers voice as a sound source, although the pressure is limited, but there is a signal level change is a very important factor which makes the microphone picked up is very strong, this factor is the microphone with singer mouth distance, the closer the signal is strong. This change can sometimes appear far beyond the limit of the amplifier, amplifier is easy to appear in clipping, of course, that in addition to a terrible voice, but also easy to burn the tweeter! In general, if the limiter is used to protect the device, the compression ratio is set at 6:1 to 10:1 or even infinity, and this becomes a limiter. With the microphone, singing like preventing the fractured when setting up between 2:1 to 4:1, the dynamic system is set to 5:1. Start time (ATTACK TIME) this function is determined when the compressor detects that the input signal is higher than the starting level, to the compressor to start the work needed time, this time is shorter, the compression of the signal more quickly but the influence on dynamic signal is also larger. Performance as: set to relatively fast start, when the compressor began to work, the general bass sound head will soon be pressed off, bass feel scattered. The starting time is slow, the compressor response to the signal is relatively slow, but the dynamic damage to the signal is relatively small. So, if you feel high frequency endurance, no problem, the appropriate slow start time, you can get a clear and powerful bass effect. If the ear is more effective, you can tune in, dont listen, put a bass plump, clear CD push big signal, let the compressor start, The recovery time (RELEASE TIME) input signal is greater than the threshold level, the compre
