6 Multi-Channel Setup
Use the following for multi-channel setup:
1. Install PurePath Console 3 with the TAS2770EVM plug-in.
2. Connect up to 8 TAS2770 EVMs together using connectors J5 and J7.
3. Attach a power supply to each board.
4. The leftmost board should have jumpers set to match the mono configuration. On all other boards,
insert a jumper on J2 and J6. PPC3 will recognize 1, 2, 4, or 8 channel setups. See Figure 4 for
details.
5. Set Jumper J13 on each board to a unique address.
6. Verify that the EVM is the default playback device by opening the sound dialog from the Windows
Control Panel as shown in Figure 2 .
7. Set the sampling rate using the Windows setting by opening Properties > Advanced. The
TAS2770EVM supports 44.1-kHz and 48-kHz sampling rates.
8. Set the bit depth as desired using the Texas Instruments USB Audio Control Panel accessible from the
system tray shown in Figure 3 .
9. Configure the device using PPC3.
10. Connect the leftmost EVM to a Windows 7+ PC with a micro-USB cable (J16).
