对乐器附加的拾音器以及传声器捡拾到的电信号,进行放大和频率校正,包括具有颤音效果的前置放大器,会更广泛地应用在各种类型的音乐演出中。该放大器有六路输入和二路输出。鉴于国内一些集成电路性能价格比的不断提高,所以在电路中选用了这类产品。
Amplifiers and frequency corrections to the instrument’s attached pickups and microphone picked up electrical signals, including the tremolo preamplifier, are more widely used in various types of musical performances. The amplifier has six inputs and two outputs. In view of the continuous improvement of the cost performance of some integrated circuits in China, the products are selected in the circuit.
