1. The position of the speakers: the main amplifier speakers of the stage are placed on both sides of the front of the stage, the subwoofer is at the bottom of the split speakers, the midrange speaker is in the middle, and the tweeter is placed at the top, because the low speakers have a small sound direction. The human body, tables, chairs and other objects absorb less. The tweeter has strong directionality and is easily absorbed by objects. The radiation areas of the two sets of speakers should overlap each other as much as possible to increase the stereo listening area. The openings of the auxiliary sound reinforcement boxes on both sides of the song and dance hall are biased toward the back area of the hall to meet the listening needs of the audience in the back area and make the sound field distribution in the hall more even. It is not advisable to place speakers on the wall at the back of the hall, to ensure that the sound and image are unified, and to avoid feedback.
2. Speaker wiring: speaker wiring must be used for speaker wiring, each of which should be more than 200 strands. The two speaker cables are of different colors. The connection to the speaker and the output terminal of the power amplifier should be strictly distinguished. The two channels are completely the same and must not be connected incorrectly.
3. The connection of audio equipment: audio equipment must be connected with audio cables, and the cable shielding wire and core wire should be firmly welded to avoid virtual welding. Pay attention to the wiring rules of the plugs and cannot be reversed arbitrarily, especially the balanced connection of the XLR plug. The balanced and unbalanced conversion connection between the XLR plug and the second-pin plug should be carried out according to the specifications. The first two devices after the mixer are connected in a balanced manner as much as possible to reduce system noise and improve anti-interference ability. In the common connection, the 2 pins of the XLR plug are connected to the high-quality core of the second- or third-pin plug.
4. Professional audio debugging, according to the connection diagram of various dance hall audio equipment, connect the mixer, audio source and peripheral equipment.
5. The input channel parameter equalization and attenuation of the mixer is in the 0dB state, and the input fader and master fader are both in a lower position.
