ifi pro idsd旗舰dac上市

说是dac，实际上是个集数播网播解码耳放于一体的玩意，延续了ifi家一贯的暴力多功能特点，左侧大旋钮可以按，可以调输入，屏幕亮度，以及音轨极性（一般没啥用，个别时候会很有用）。左边第二个小旋钮也可以按，用来调5种不同的filter，升频（可到dsd1024，768kPCM），还有连接路由器无线接入网络。小旋钮下的开关是和pro ican一样的胆/石模式选择，右侧大音量旋钮没啥可说的，3个推力档，遥控器的红外接收，6.3单端口，3.5单端口，还有2.5平衡口。机器背面，厉害了！双3pinxlr平衡输出，rca输出，网线口，usb-a、b口（可以直接插u盘或外部硬盘），spdif同轴光纤口，sd卡槽，xlr数字输入，bnc时钟入（用来接外部时钟，又是个大坑），bnc时钟出（用自己的时钟输出）。这个玩意里的时钟据说用的是自家母公司amr dp-777上的技术。因为主要是用作解码，耳放没那么厉害，最高输出16欧下4w每通道。棒棒，就是有点贵，2500美元
