Using The TPA0103 EVM With the Plug-N-Play Evaluation Platform

3.3.4.2Mute/Mode Select (JP6)

A 3-pin jumper header (JP6) on the platform, functioning as an SPDT switch, routes the control signal from the headphone jack to either the mute control input pin or the mode control input pin of the evaluation module.

JTo switch the TPA0103 amplifier module between center channel speaker and stereo headphone modes using the control signal from the platform headphone jack, jumper JP6 to MODE

JFor center channel only or 3-channel output modes (as selected by EVM jumper S2) leave JP6 open.

3.3.4.3Mute/Mode Polarity Select (JP8)

A second 3-pin jumper header (JP8) on the platform selects the control signal polarity by connecting either the active-high or the active-low line from the headphone jack to jumper JP6.

JWhen JP6 is set to Mode, set JP8 to Hi.

JWhen JP6 is open, JP8 settings are ignored.
