-Evaluation Module Preparations

6)To force the EVM into a BTL output mode, set jumper J1 to OFF. To force the EVM into a SE output mode, set jumper J1 to ON.

7)To force the EVM into using the LINE inputs, set jumper J2 to OFF. To force the EVM into using HP inputs, set jumper J2 to ON.

-Control Inputs

8)To allow the amplifier IC to switch from the LINE inputs to the HP inputs when the output switches from BTL output mode to SE output mode and vice versa, set jumper J3 to ON. To allow the inputs and output modes to switch independently, set jumper J3 to OFF. Connect control lines to the various module control input pins as needed.

9)SE/BTL: A high voltage applied to this pin selects the SE output mode; a low voltage or float on this pin selects the BTL output mode. Refer to the TPA6030A4 data sheet for trip level information.

10)SHUTDOWN: A low voltage applied to this pin shuts down the amplifier IC on the module; a high voltage or float on this pin allows normal operation. Refer to the TPA6030A4 data sheet for trip level information.

-Power-Up

11)Verify correct voltage and input polarity and set the external power supply to ON.

The EVM should begin operation.

-Volume Control

12)Potentiometer R1 (VOLUME) sets the BTL volume, which can range from –40 dB to +36 dB using 2.53 dB steps. Turning the potentiometer clockwise increases the volume; turning counterclockwise decreases the volume. To mute the volume (–80 dB), turn the potentiometer, R1, as far as it will go in a counterclockwise direction. Refer to Table 3–2 in the Reference chapter for a list of the volume levels.

13)The SE volume may be set independently using potentiometers R2 (SEDIFF) and R3 (SEMAX). SEDIFF set the difference between the BTL volume and the SE volume, while SEMAX sets the maximum volume in SE mode.

14)Turning potentiometer R2 (SEDIFF) clockwise decreases the difference between the volumes; counterclockwise increases the difference.

15)Turning potentiometer R3 (SEMAX) clockwise increases the maximum SE volume; counterclockwise decreases the maximum SE volume.

For more information on volume control operation, see the TPA6030A4 data sheet.
