Active fret, frets waterproof active, outdoor wall-active frets, Hui Chi Pu Technology

Roughly speaking, if you like the frets with a modern look, as long as with subwoofers, do not have to worry about its quality performance due to design reasons, not as good as the traditional style of the speaker (only on the principle of analysis, without regard to subjective feelings of judgment the sound quality is good or bad). It frets that 360 sound field system, the sound field generated from the theoretical analysis must be better than conventional speakers, which sound more suitable for watching movies and music. Hi-fi amplifier with all-aluminum outdoor waterproof frets, (1) set the stage and visual effects consistent with those requirements; hi-fi amplifier with all-aluminum outdoor waterproof frets, (2) by the building's size limit should not be scattered arrangement. When centralized arrangement, enabling the audience area of ??direct sound more evenly and minimize acoustic feedback. Installing a centralized system with a single speaker or a set of speakers. For example, the stage-shaped hall, the speaker system is close to natural sound source, usually placed at the top of both sides of the proscenium frame or a table. The advantage of this arrangement is that the sound from the stage direction, viewed from the audiovisual consistent sense of direction, more natural hearing. The disadvantage is complex shape (such as Vision Taiwan too deep) or large halls, the sound field is not easy even, even in the back seat of the sound level may be low. In addition, the centralized arrangement because the speaker microphone near the stage, prone to feedback whistle. Project design should pay attention, you should choose a single strong directional speakers or sound columns, which help to overcome the acoustic feedback. When the speaker is disposed above the proscenium, from overcoming the effects of acoustic feedback than look good on both sides of the proscenium arrangement. For space height, the higher the occasion, the more obvious problem is the front row of the audience will feel the sound comes from the head, in order to overcome this drawback, the addition of auxiliary speaker can proscenium (the speaker power to assign smaller), so front sound field uniformity, so that the sound down. When the speaker is arranged on both sides of the table, the sound of feedback is quite conspicuous because, as speaker and sound column, they point to the relatively poor level of direction, simply with the power of two speakers hung on both sides of the proscenium in on Hall Central seat audience will produce double the sound source ** listeners uncomfortable, solution to the problem is the speaker as hung higher, due to increase auxiliary speaker. Another example are the other four halls of the audience, such as the Coliseum, the speaker is disposed over the central hall of the game. Place microphone performance area, it should pay attention to the speaker's directivity control. Due to the complex shape of the hall and diverse, centralized system may take many speakers fit together, according to the configuration of the curve shapes.
