Quality identification of customized outdoor column speaker

1. In response to many people's belief that the customized outdoor column speaker power amplifier is "the sinker the better", inferior power amplifiers all use toroidal transformers, and many of them use feverish Shuanghuan cattle. However, the quality of the silicon steel sheet of this type of ring cow is very poor, and the winding process is not enough. This results in low efficiency and low actual power, especially when it is quiet, it is easy to hear the "humming" of the ring cow.

2. The customized outdoor column speaker is a domestically-made capacitor with a large head and a small capacity to charge imported brand-name capacitors. Some manufacturers even used the backlog of early capacitors to repack and recharge new capacitors. The actual withstand voltage and capacity of these capacitors do not reach the nominal value at all. This type of capacitor is generally lighter than the genuine product.

3. Customized outdoor column speakers are inferior power amplifiers that often have 5-channel or even 7-channel output. But in fact, the surround and center channels of many power amplifiers come from the series resistance of the left and right main channels. Although some power amplifiers are equipped with independent amplifier circuits, they only undergo simple delay processing, and there is no dedicated decoding circuit and sound field processing circuit at all. When identifying this type of power amplifier, if it is found that the surround and center channels cannot be adjusted individually, it must be a false surround from the main channel with a resistor in series. If it has Dolby Pro Logic Decoding function and no noise test. Or the surround speakers also sound when only a mono signal is input, the power amplifier is a pseudo surround sound power amplifier.
