PRO TWO is a passive dual-channel DI box. No need to install battery or provide phantom power to make it work.
 
PRO TWO has a pair of built-in UNiKA-PROTM EI9AE3R3 1.25:1 isolation transformers, which have 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 TWO is particularly suitable for electronic musical instruments, recording studios and fixed installation projects that do not use mixers. It converts high-impedance signals into low-impedance balanced signals, which facilitates extending the wiring distance and blocking interference.
 
The PRO TWO uses a pair of TRS socket on the input, and a pair of TRS through out are convenient for musician to pass the direct signal to the instrument amplifier. 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 GND/LIFT button to quickly eliminate ground noise.
