Using the EVM Software
3.1
Connect the GUI to the EVM
Once the properties window selections have been made, go to the menu Target
→
Connect.
This sends the initialization commands to the device. Master volume is in mute. Select the master volume
function. Type the required volume in the properties window. For TAS5707/09, type 0 dB. The difference
is due the power stage gain in both devices. At this time, audio, if connected properly, plays through the
device. Check All channel shutdown button. It must be un-checked. When the Connect command is
issued, if an error appears indicating a USB problem, check the connections, and press the USB RESET
button on the controller board. Then disconnect and re-connect from the Target menu.
