PRO MMD is a dedicated DI box for passive multimedia, without the need to install battery or provide phantom power.
PRO MMD has a pair of built-in UNiKA-PROTM EI30A10E 1+1:1+1 isolation transformers which has a special copper foil layer and a dedicated ground layer, which allows this device to restore high signal/noise ratio and dynamic sound, and can avoid unnecessary leakage caused by radio frequency interference, ground interference and potential difference.
PRO MMD is particularly suitable for play deck, computer, and video equipment. It converts high-impedance signals into low-impedance balance signals which is convenient for extending the wiring distance and blocking interference.
The input end of PRO MMD adopts two TRS sockets, a pair of RAC sockets and a mini TRS socket, any one socket can be used as input or through out. In addition, it is equipped with a 0/-20dB attenuation switch, which is suitable for various types of audio signals with high and low impedance. The output terminal is also equipped with a ground/floating button, in order to quickly eliminate ground noise.
