MHPTV TX User Manual 4.7 VOLTAGE ADJUSTMENTS (Available in CTL-M) When the transmitter is not running at its rated power, it may have headroom in power level. So that reducing the output DC voltage of PSUs will help improve the system efficiency. Optitune is only available in the model of CTL-M controller. We provide a One-Button feature reducing all PSUs voltage to 46V for those users who need it. Also, a One-Button feature bringing PSUs voltage back to the regular 50V. Local Control: 1.
