BD34704KS2
MUS-IC™ Series, 具备μ-step音量 7.1ch高音质声音处理器
为提升音质，对所使用的运算放大器的特性和元器件的配置配线进行了修改，实现了输入输出间无音质恶化的8ch独立音量。具备罗姆的μ-step音量技术，可尽量降低播放音乐的过程中切换了音量时的爆破音，适用于高品质的整机。内置最多可支持Zone3的单端12路输入选择器、双系统多路输入选择器，可连接大多数信号源。

特点：
- 12ch input selectors (It is extendable to up to 18 in case of no use other functions such as Multi input, REC output and SUB output)
- Micro-step volume can reduce the switching pop noise during volume attenuation
- Zone 3 is supported
- 2ch sub-volume for zone output that is available for independent control with a micro step function
- 2-wire serial bus control, corresponding to 3.3/5V
