Weak current College】 【professional effects how-to manual.

Effects of the basic effect type audio pitches, special harmony source effect three categories. Digital effects are stockpiling have dozens or hundreds of results, some effects and parameters balanced, noise gate, actuator and compression/limiting the capability. Users can choose according to their own need to select the appropriate effect type.
1. the composition of the indoor sound effects: l direct sound: Direction audience directly from the sound source to broadcast get sound. Sound pressure level of the dissemination is inversely proportional to the square of the distance. The distance the doubling of the sound pressure level decreases 6dB. And sound absorption characteristics of the room.
Near-time reflections EaryRefections peripheral interface once or twice. After reaching the audience at the reflection of sound. Near-time reflections and direct access to the sound of the time delay between to 30ms, but put them together, overlaid on the near time reflections on increasing pressure level and the sharpness is good and sound absorption characteristics of reflection interface.
Sound mix: sound than the direct-to-late-than 30ms of reflection claimed to (mixed sound), the mixed sound to help people identify room volume size. The music program is to increase the richness of the music, it provides sweetly components at the same time and near-time reflection sound effects with masking, voice clarity and intelligibility of language. Therefore, this component is not, and should not be too large.

L the reverberation time ReverberationTime is reached steady state sound source, stop talking, indoor sound pressure level attenuation 60dB.

1: adjustment of the reverberation time. Length of reverberation time, give to the room to hear the sound effects. Effects of reverberation time length can be determined based on the following factors: the larger the volume l, sound-absorbing enough room (no sound device's room), the effects of artificial reverberation time to short.

L male singing the reverberation time should be shorter; girl singing the reverberation time may be longer.

2: professional singer reverberation time should be shorter, otherwise it will damage the original characteristics of timbre; amateur singers available long reverberation time, to cover up the sound. Environmental noise big occasions the reverberation time can be extended. L sound volume is large, the reverberation time adjustable have shorter!

3: pre delay adjustment: pre delay is to control the effects of time interval. ECHO is the same sound has reached the time difference is more than 50Ms. Mainly used to improve the performance of the vibrato effect.

4: echo effect of feedback: this parameter controls the number of ECHO is available from 0% ~ 99% adjustment. Rate the most hours, feedback effects actually is a delay, maximum is formed of endless echoes, the General increase in about 30%.
