我可以用盡佢 ...
case 1. mojo / dp-x1 -> jotunheim -> Genelec active speakers or balanced headphones
or LKS DAC XLR out -> jotunheim XLR in -> Genelec active speakers or balanced headphones
case 2. pc1 -> jotunheim usb -> Genelec active speakers / IEM / Balanced headphones
case 3. Pc2 -> jotunheim RCA in -> Genelec active speakers / IEM / Balanced headphones
or
case 4. Monitor RCA out -> jotunheim RCA in -> Genelec active speakers / IEM / Balanced headphones
Perfect match with my gears
