Expensive fix if your notebook’s audio is not enough for you
M2Tech has just introduced a high-performance multi-channel USB audio digital-digital converter (DDC) on its official website.The small pen drive plugs into any USB 2.0 port, and outputs one coaxial SPDIF digital audio output. The output signal supports a maximum resolution of 24-bit, with a 192 kHz sample-rate.
The device features standard USB Audio Class 2.0 driver interface and thus requires no drivers for MAC and is Linux compatible.
It measures 20 mm by 102 mm by 22 mm, and weighs 33 g. That is 0.78 inch by 4.01 inch by 0.86 inch with a weight of 1.1 ounces in imperial.
The price is almost 298 USD for US buyers or almost 223 EUR for European customers.
