UIM-1

USB DAC Optional Board for SRM-T8000

UIM-1 is USB DAC module to be installed in the optional slot (LINE 4) of SRM-T8000.Its originally developed in Japan. On a circuit, one ESS9038Q2M is installed on each side in monaural mode. A circuit after DAC, including a low-pass filter, is completely separated by for the left and the right channel. For analog sections, carefully selected parts are used and for CPU, DAC (digital/analog) and operational amplifier, independent power supplies are installed to reduce the interaction of noises. During native playback of Windows (with driver), UIM-1 supports DSD audio sources up to 22.5MHz.
