产品介绍DESCRIPTION产品说明The ZL2313 is a volume, tone (bass and treble) balance (Left/Right) and fader (front/rear) processor for quality audio applications in car radio and Hi-Fi systems. Selectable input gain and external loudness function are provided. Control is accomplished by serial I2C bus microprocessor interface. The AC signal setting is obtain –ed by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Tecnology, Low Distortion, Low Noise and Low DC stepping are obtained. 产品属性FEATURES产品特点 Input Multiplexer: 3 Stereo Inputs Select Table Input Gain for Optimal Adaption to Diferent SourcesLOUDNESS Funtion Volume Control in 1.25dB Steps Trebleand bass control Four Speaker Attenuators: 4 Independent Speakers control in 1.25dB Steps for Balance and fader facilities independent Mute FunctionsAll Functions Programmable via serial I2C bus 其他说明Other description please see the product specification.此产品图片仅供参考，以实物为准。交易说明Please directly contact us, thank you!
