THD+N step-up on
The graph below report the THD+N vs. Pout of a TDA7572 board with step-up on and 50Hz
input sine wave. Condition and step to made the board working are:
1. connect a voltage supplier to the connector J1: Positive terminal (max 14V) connected
to L14V, ground terminal connected to -Vs.
2. connect the differential input signal on INP and INM BNC input or connect the single
ended input on the INP BNC and short cut the INM BNC.
3. connect the load of 4Ohm to the connector J2.
4. turn-on the device by means of MODE0 switch.
5. put in play the device by operating on MUTE switch
