Setup the TAS5010−5112F2EVM With the S/PDIF Input
3-3 EVM Board Operation
3.2 Setup the TAS5010−5112F2EVM With the S/PDIF Input
Connect the EVM board as shown in Figure 3−2. Select between coaxial or
optical input signal at the input selector switch (S100).
Press the lever at S320 in the direction of U360 if the TAS3002 DAP is wanted
in the signal path (recommended during normal listening tests). There is no
attenuation if DAP is bypassed. If the DAP is in the signal path, the start-up
volume level depends on what is programmed in the serial EEPROM on the
EVM board. The default startup volume level is initially programmed to 12 dB
below full scale, which on some speakers still might be loud. The default
volume level can be changed with the DCT software on the PC.
The following are the conditions for standard setup:
1) All jumpers are in default position.
2) Speakers, power supply, and if required a cable for PC communication are
initially connected to the EVM board.
3) The TAS5010−5112F2EVM can be powered with either one or two power
supplies (see the Power Supply section). Power supplies are initially
switched OFF.
4) Music player is initially switched OFF.
5) PC connection is optional.
