3 Wire Speaker Connection
TAS2564 supports a 3 wire speaker connection where an additional Voltage sense pin provides feedback
for a center tap speaker coil voltage. This helps detect mechanical offset of the speaker to maximize cone
excursion in both directions. Unless a 3 wire speaker is specifically being used to evaluate device
performance, it is recommended to follow the standard 2 wire configuration.
To enable 3 wire mode on the EVM do the following:
1. Move the shunt on J15 and/or J14 to the 3W position. (Pins 3-4)
2. Connect the center speaker wire to the sense terminal of J8 and.or J5
