Installation
Connect the MC-57xx and the TAS5706EVM2 boards by locating pin 1 on each board, indicated by a
small white triangle. The MC-57xx plugs down onto the TAS5706EVM2 board (i.e., the TAS5706EVM2
board fits underneath the MC57xxPSIA board). Pin 1 on each board must be connected to each other.
Install the EVM software on the PC before powering up the board. After connecting the loudspeakers or
other loads, power supplies, and the data line, power up the 5-V power supply first; then power up the
PVCC power supply. It is recommended initially to set the PVCC level to 10 V, then ramp it up to 20 V to
verify cable connections.

the GUI. Check versions for any updates to the GUI on the

THE GUI come ups as shown in Figure 7 .
Select the appropriate tab; in this case, select the TAS5705/TAS5706 tab.
It has two subwindows. One shows the Process Flow window. From the Process Flow window, each of
the signal processing function tools can be selected by clicking on it. The Biquad GUI and the DRC GUI
can be opened by using the right button of the mouse. This window also shows input select, Mode select,
Channel, and Master Volume. All functions are shown in the order that they are in the device.
The other subwindow, Properties window, has the properties where a user can update by selecting from
the available options. The properties that are available depends on the device selected. From the main
window, the user must set three properties before connecting to the EVM.
Select the device, Enable/Disable auto bank switch function and set the sample rate. The TAS5706A
automatically detects sample rates. The setting here is simply to synchronize the GUI and the device.
