• intros：{"brand_intro":"山灵（Shanling）成立于1988年，是中国老牌Hi-Fi音频厂商，前身为深圳山灵电子厂。创始人李建华从CD播放器代工起步，逐步转型为自主品牌，在解码耳放、便携播放器领域积累深厚。山灵以\"模拟味\"调音著称，核心技术包括FPGA数字滤波和OPA运放架构。品控方面，每台设备经过-20℃至60℃极端环境测试。UP4是山灵在蓝牙收发领域的入门力作，主打便携与音质平衡，深受年轻发烧友喜爱。","product_intro":"山灵UP4是一款蓝牙解码耳放，支持黑胶唱机信号发射功能。核心卖点：双ES9219C DAC芯片、支持aptX HD/LDAC、3.5mm+2.5mm平衡输出。适用于黑胶玩家搭配高阻抗耳机使用，或作为桌面音响的无线中转站。相比飞傲BTA30 Pro，UP4更小巧便携（仅40g），但接口较少（无光纤/同轴）。竞品如艾巴索DC05在推力上更强，山灵在蓝牙编码兼容性上更全面。","key_specs":{"蓝牙版本":"5.0，支持LDAC/aptX HD/aptX LL/AAC/SBC","接口类型":"3.5mm单端+2.5mm平衡输出，RCA输入需转接线","传输距离":"12米（无障碍），连接稳定","供电方式":"内置600mAh锂电池，续航约10小时","音频编码":"LDAC（990kbps）支持，双DAC设计","适用人群":"便携需求用户、黑胶+高阻抗耳机玩家"}}
