Quick Start

Configure the AC-MB for the USB audio (TDM) and the TAA3020EVB for the onboard microphone inputs.

The GUI comes with preset files to that can be used for easy initial setup. Select the Load preset option in the top corner of the GUI and load the On Board Microphone setting, as shown in Figure 8-1 and Figure 8-2. Be sure to populate the jumpers described in the settings as described in Table 4-1.

The default state for the TAA3020 is standby mode and, with the exception of the channel digital volume, all device configurations must be done in standby mode. The TAA3020 does not provide a digital audio output in standby mode. Figure 8-4 shows how to change the mode from standby to active.

When active mode is enabled, any controls not configurable in active mode are grayed out. These controls can be changed again when the device is brought out of active mode. Figure 8-5 shows which controls are disabled.
